Understand that insects fill various roles in their environments. Explain how insects populations adapt over time to survive changing environments. Describe ways that insects have positive and negative impacts on human populations. Generate excitement about insects, and identify careers that are connected to insects. Lesson Plan Topics Hello, Insects What is an insect? Why do we study insects? What are the economic and health impacts of insects? How do we collect and study insects? What are some common insect groups? Insect Taxonomy What are the parts an insect? How do we classify insects? Activities: Classify insects and photographs of insects by grouping them into seven major orders Insect Life Cycles What are the stages of insect development for complete, gradual, and incomplete metamorphosis? Activities: Sort and arrange the life cycle stages of butterflies, lady bugs, grasshoppers, crickets, and other insects. Identify connections between body forms and roles in the environment for each life cycle stage. Build models of insects. Insect Roles Identify the jobs that insects do in their environments and ways that they interact with other species. Activities: Simulate interactions between predators and prey and observe the effects on population sizes. Make a diagram of a food web that includes insects. Insect Feeding and Movement Explain how the mouths, legs, and wings of insect species help them survive in their environments. Activities: Model the structures and functions of insect mouths. Compare and contrast the functions of insect legs and wings. Design an insect to fit a certain environment. Insect Adaptations Explain how insect populations change over time (natural selection/evolution) as the environment changes. Identify ways that insects are adapted for survival. Activities: Model changes in a moth population that result from predation. Look at photographs of insects and identify their adaptations. Insect Habitats Select insect habitats and analyze species diversity, give examples of ways that insects create habitats, and identify connections between insects and people. Activities: Use hula hoops to sample and analyze the insect species found in outdoor habitats. Search for evidence of insects in outdoor environments. Explore ways that insects create their own habitats. Identify evidence of positive and negative connections between insects and people. For more information, please contact us.

AMAZING INSECTS! “Intro To Insects: Why Study Bugs?” (DRAFT) Grade Level: Subjects: Duration: Program Type: Setting: Key Terms: Activity Adapted From: Maryland State Standards: 3-5 Insects 10 minutes Teacher/Instructor Classroom Elizabeth Hill, Basic Entomology Programs Grade 3- 5: Standard 3.0: Life Science Of all organisms that students can study, why are insects a great choice to consider for studying the many aspects of Life Science required in the Science Standards? 1. Insects represent the majority of species on the planet Earth. Depending on the source, the percentage can vary from approximately 50 – 60% of all living species are insects. The University of Michigan puts the total number of species currently identified at 1.4 million1. It is well known there are lots of species of all types of organisms still to be discovered, but this is good estimate for the time being. 2. Everyone is familiar with and comes in contact with insects in their lives. Most students may not realize how often they interact with insects, but it occurs almost daily. From the stink bug in our house, the fly on our food, fleas on our pets or the butterfly and bees on flowers, insects are everywhere. 3. Insects have a profound effect on human life and human history. From the food we eat to the diseases we contract, insects play a crucial role in human existence. According to the US Department of Agriculture, about 1/3 of food crops are pollinated by insects. Insects can also be major pests of human food – plant and animal. Human populations are greatly influenced by insect vectored diseases. Not only do these diseases affect human life, medical expenses and related prevention and control costs have a large economic impact. 4. Insects illicit an emotional response. It may be “I hate wasps because they sting” or “I love butterflies, they are so beautiful”; most people have strong feelings about insects. Studying them is a great way to connect with emotional responses and learn more about the role insects play in our lives. 1 The University of Michigan: “Threats to Global Biodiversity” http://www.globalchange.umich.edu/globalchange2/current/lectures/biodiversity/biodiversity.html Developed by Elizabeth Hill, Faculty Extension Asst., University of Maryland Extension, Kent County 2/2014 AMAZING INSECTS! “Insect Habitats” (DRAFT) Grade Level: Subjects: Duration: Program Type: Setting: Key Terms: Activity Adapted From: Maryland State Standards: 3-5 Insects, Habitats, Biological Diversity, Survival 60 – 75 minutes Student Centered, Teacher Led Classroom and Outdoors Habitats, Diversity, Observation, Survival, Data Grade 3- 5: Standard 3.0: Life Science Grade 3 – 3.0 Grade 4 – 3.0 A 1a, D 1 a, F 1 a-b Grade 5 - 3.0 A 1 b, d Goal: Students will learn that organisms live in various habitats and that those habitats provide the resources needed for survival. Specifically, children will learn about insect habitats and investigate local environments and the insects that live there. Materials - Per Class (20-30 students): 4-6 hoola hoops of equal size, pencils, magnifying glass (recommended), 1 thermometer per group, insect reference guides (book, internet or handout), Insect Habitat Observation Sheet Extension Activity: Insect nets and plastic containers for collecting Background: Insects are one of the most diverse groups of animals on the planet. They comprise over 50% of all species on Earth. Insects live in diverse habitats from oceans to the arctic as well local environments. The more diverse the habitat, the greater the number of species that live there. Data collection is a key component of scientific study. Introduction: 1. Ask students to explain what a habitat is and what a habitat consists of. a. Habitat: The place or type of site where a plant or animal naturally or normally lives or grows (Websters) b. Habitat consists of food, water, shelter, resources, resting place, etc. 2. Have students name some habitats they know and what habitats are around them. Procedure: 1. Divide the group/class into 4-6 smaller groups, depending on the number of hoola hoops available. 2. Give each student an Insect Observation Sheet, pencil and magnifying glass (if available). 3. Determine length of activity and number of observations 4. Give a brief overview of common insect groups. Can use handout or insect reference guides. Activity: 1. Each group of students selects a different habitat with at least one being a very diverse habitat. Selection will depend on locations available. Suggestions include lawn area, flower beds, shrubs and small trees, wooded area, weedy area, farm field, etc. 2. Students record the habitat characteristics on the Insect Habitat Observation Sheet including weather conditions, plants etc. 3. Each student develops a hypothesis on the number of organisms they expect to observe based on the characteristics of their chosen habitat. 4. Allow observation of organisms in hoola hoop area for specified time, 15 – 30 minutes 5. Students should record numbers of insects and organisms and name them if they can. 6. Repeat observations as time permits. a. Variations: observe multiple times in 1 day, observe at same time for several days in a row b. Graph number of insects observed over several data collections Optional – Students can draw 1 or more insects observed in their test area. 7. Using reference guides or the internet, have the students identify 1 or more the insects they observed. Debrief: 1. Ask the students what type of habitat they chose. 2. Have the students share their results with the other groups. 3. Did more diverse habitats (with more types of plants, water, etc.) contain more organisms or a greater variety of organisms? Extensions: 1. Using Nets or Plastic Containers, students can collect insects/organisms found in their habitat. Have students observe, draw, identify these insects. 2. Students can make a Habitat Insect Collection. *Have kids determine area of hoola hoop Calculate the Area of a Circle a = pi * r2 The area of a circle is its radius squared times pi. definitions a = area of the circle r = radius of the circle pi = Π, approximately 3.1415927 From: http://www.calculateme.com/cArea/AreaOfCircle.htm University of Maryland Extension programs are open to all persons and will not discriminate against anyone because of race, age, sex, color, sexual orientation, physical or mental disability, religion, ancestry, or national origin, marital status, genetic information, or political affiliation, or gender identity and expression.

AMAZING INSECTS! “Insect Classification and Taxonomy” (DRAFT) Grade Level: Subjects: Duration: Program Type: Setting: Key Terms: Activity Adapted From: Maryland State Standards: 3-5 Insects, Biological Diversity, Adaptation 50 – 60 minutes Student Centered, Teacher Led – Active Classroom Taxonomy, Orders, Diversity, Insect Classification Elizabeth Hill, Grade 3- 5: Standard 3.0: Life Science Grade 3 – 3.0 Grade 4 – 3.0 A 1a-d, D 1 b-c Grade 5 - 3.0 A 1 Goal: Students will understand that all organisms are classified and grouped by similar traits. Specifically, students will learn to group insects into 7 Orders. Materials - Per Class (20-30 students): A complete listing of insect orders, 4-6 sets of 35 Insect Order Cards, 4-6 Insect Taxonomy Keys, and 4-6 Insect Taxonomy Answer Keys. Extension Activity: “Stink Bug ID Comparison Sheet” Background: Insects are one of the most diverse groups of animals on the planet. They comprise over 50% of all species on Earth. Insects are classified in over 30 Orders, each order representing a diverse member group. Each group has characteristics that can be used in sorting and identifying. Introduction: 1. Ask students to name any group of organisms and some members of each. Examples may include: a. Birds – hawks, robins, geese, gulls, ducks etc. b. Mammals – dogs, raccoons, rodents, etc. 2. Show students of list of all insects orders and discuss their diversity. Have students name some insects they are familiar with and what insect group they belong to. a. Example – Insect: Lady bug, Group – Beetles b. Example – Insect: Honey Bee, Group – Bees and Wasps 3. The 7 most common insect orders are featured in this exercise: Beetles (Coleoptera), Butterflies and Moths (Lepidoptera), Flies (Diptera), Bees and Wasps (Hymenoptera), True Bugs (Hemiptera), Plant Bugs (Homoptera) and Grasshoppers, Crickets and Katydids (Orthoptera). Procedure: 1. Divide the group/class into 4-6 smaller groups, depending on the number of cards sets available 2. Give each group 1 set of 35 insect group cards (7 orders, 5 representatives of each order) 3. Give each group 1 Insect Taxonomy Key 4. Briefly discuss the traits of all 7 orders discussed on the Insect Taxonomy Key pointing out key characteristics of each order Activity: 1. Allow 10 – 15 minutes for each group to sort their insect cards into the 7 identified orders. They are encouraged to use the taxonomy guide that highlights each Insect Order characteristics. 2. Give a hint that there are several “trick” examples in the card sets that might look like they belong in one order, but really belong in another. The students must observe the species card carefully. 3. After the student have completed sorting, hand out the Insect Taxonomy Answer Key. 4. Allow the groups to “correct” any species they identified incorrectly. Point out the trick species and see which groups got identified them correctly. Optional – A). Time the groups and see how quickly they can group their insect orders B). Record the number correct in each order set. C). Combine both A and B – which group had the fasted time and had the greatest number correct? Debrief: 1. Ask the students if it was difficult or easy to group the insects? Which group was hardest/easiest to put together? 2. What order characteristics stood out that made an order easier to group together? For example, scales on the butterfly and moth wings, large back jumping legs on the grasshopper order or the plant bugs holding their wings like tents. 3. How can we use the same principals of grouping to other organisms? 4. Have the students identify the trick species, which groups they belong to, and why they looked like they belonged in another group. Example – the moth that looks like a wasp (mimicry). Why is mimicry a benefit to the moth? 5. Are their Real World examples of learning to sort insects? For example, see Extension #5 Extensions: 1. The 7 orders represent both Incomplete and Complete Metamorphosis (change). Look at how insects grow and develop and what type of metamorphosis each Order goes through. Look at the steps of each metamorphosis type (Incomplete or Complete) and how they differ. 2. Look at additional insects from the 7 orders to see if students can group them with already identified orders. 3. Look at other less common insect orders like Dragonflies (Odonata), Termite (Isoptera), Fleas (Siphonaptera), Mantids (Mantodea) etc. and discover representatives of these groups. 4. Have groups pick one of the 7 insect orders and research their significance to humans – disease vectors, pests or beneficials, food, aesthetics, hobbies, etc. 5. Utilize “Stink Bug ID Comparison Sheet” to show how to tell the difference between the non-native Brown Marmorated Stink Bug pest and 2 native brown stink bugs native to Maryland. 6. Compare Insect and Human Classification.

AMAZING INSECTS! “Insect Life Cycles” (DRAFT) Grade Level: Subjects: Duration: Program Type: Setting: Key Terms: Activity Adapted From: Maryland State Standards: 3-5 Insects, Life Cycles, Metamorphosis 60 – 75 minutes Student Centered, Teacher Led Classroom Metamorphosis, Life Cycles, Larva, Nymph, Pupa Elizabeth Hill – Lesson on Metamorphosis Grade 3- 5: Standard 3.0: Life Science Grade 3 – 3.0 Grade 4 – 3.0 C 1a-b, D 1, E 1 a, F 1 Grade 5 - 3.0 E 1 a-c Goal: Students will learn that insects grow using various methods of metamorphosis or change. Students will learn that insects are divided by the type of metamorphosis they go through. Students will also understand that metamorphosis is driven by energy in the form of food. Materials - Per Class (20-30 students): playdoh or modeling clay, 4-6 life stages card sets, 4 Handouts – Gradual, Incomplete and Complete Metamorphosis Life Cycles, Insect Life Cycle Models (if available). Extension Activity: Background: Insects are one of the most diverse groups of animals on the planet. They comprise over 50% of all species on Earth. All insects go through Incomplete or Complete Metamorphosis Introduction: 1. Introduce the concept of organism growth. How does a human grow? What is a life cycle? 2. Ask students if they know any of the stages of an insect life cycle. Incomplete: egg Complete: egg nymph larva pupa adult adult 3. Have student define Metamorphosis: metamorphosis = change Any marked change in the form and structure of an animal in its development from embryo to adult, such as a chrysalis to a butterfly or tadpole to a frog. (Funk & Wagnalls Dictionary). Procedure 1: This exercise can be done in small groups or individually 1. A 2. D 3. G Activity 1: Life Cycle Stages Matching Game 1. Each 2. . Procedure 2: This exercise can be done in small groups or individually 1. Allow student or group to choose one of the Life Cycles from the Gradual, Incomplete and Complete Metamorphosis Handouts a. Variation – have students research the life cycle of an insect of their choosing 2. Activity 2: Life Cycle Models Debrief: 1. Ask 2. Have t 3. Did Extensions: 1. To be able to move into each stage of an insect’s life cycle, they must shed their exoskeleton. Investigate exoskeletons – what an exoskeleton is, what they are made of, what happens to them as the insect grows, and how they are shed. 2. Have insects in the classroom and observe and record each life cycle change an how long each stage lasts. Determine if the insect goes through incomplete or complete metamorphosis. a. Example in insects that can be easily raised in the classroom: mealworms (darkling beetles), butterflies (painted ladies, monarchs, swallowtails, etc.), cockroaches, mantids and more. b. When raising insects, make sure to provide housing, habitat and food appropriate to the species. c. Insects can be collected from the outdoors or ordered from biological supply companies.

Explain ways that individuals and groups of organisms interact with each other and their environment. a. Identify and describe the interactions of organisms present in a habitat. Competition for space, food, and water Beneficial interactions: nesting, pollination, seed dispersal, oysters filtering as in the Chesapeake Bay, etc. Roles within food chains and webs: scavengers, decomposers, producers, consumers. b. Explain that changes in an organism’s habitat are sometimes beneficial to it and sometimes harmful. Grade 5: 3.0 Life Sciences A. Diversity of Life 1. Explain the idea that in any particular environment, some kinds of plants and animals survive well, some less well, and some cannot survive at all. a. Identify and describe features and behaviors of some of the plants and animals living in a familiar environment and explain ways that these organisms are well suited to their environment. b. Based on information about the features and behaviors of animals and plants from very different environments describe reasons that they might not survive if their environment changed or if they were moved from one environment to another. MD Env. Lit. Standards Standard 4.0 Topic A: Cycling of Matter and Energy Indicator 1: Explain how organisms are linked by the transfer and transformation of matter and energy at the ecosystem level. Goal: Students will understand that insects and other living things take on specific roles, and that those roles affect all other parts of the ecosystem. Materials: Role poster w/ rules, 10 plastic buckets/containers, about 200 pom poms, 20 small pieces of fabric, hula hoop, small pieces of construction paper Background: Insects are one of the most diverse groups of animals on the planet. They exist in nearly every environment on Earth and are involved in many important ecosystem functions. Insects interact with other living things in many ways, some of these interactions are viewed as being beneficial to humans, such as pollination and the removal of insect “pests.” Other interactions, such as the spread of disease and the destruction of crops by “pests” are harmful to humans. In this activity, students will gain an understanding of the role that some local insects have in the Maryland ecosystem. The University of Maryland Extension programs are open to any person and will not discriminate against anyone because of race, age, sex, color, sexual orientation, physical or mental disability, religion, ancestry, national origin, marital status, genetic information, political affiliation, and gender identity or expression. DRAFT Intro (optional): - Ask students if they have any jobs or responsibilities at home or school. - Make a list from the responses - Ask students to think of some jobs that insects need to do (pollination, eating, etc.) - Explain that students will have the opportunity to do some of these insect jobs Procedure: 1) Establish a playing area, indoors or outdoors that is large enough for at least 20 students to move around in. 2) Place 10 buckets around the playing area in any way the instructor sees fit. Indoors: using desks and tables works well, as long as there are aisles to move through Outdoors: using picnic tables and benches work well, buckets could sit on the ground 3) Place a hula-hoop (beehive) somewhat separated from the buckets (plants). 4) Place approximately 10 pom-poms in each bucket 5) Place all 20 pieces of the cloth pieces in one bucket 6) Spread the remaining pom-poms on the ground throughout the playing area 7) Divide the class into groups and assign them roles, numbers can vary, but a good starting ratio for a class of 20 would be (it is recommended to assign roles using colored pieces of paper that match the roles poster): 7 Honey Bees (green) 2 Hercules Beetles (purple) 3 Lacewings (pink) 1 House Wren (blue) 7 Aphids (red) Bee hive ~50 Pom-poms Plants (start with 10 pom-poms each) Activity: 1) Use the directions on the insect role cards to describe what each insect will do 2) Assign motions and/or sounds to each animal group so that they can identify one another. Examples: Hercules Beetle: flexes arms and says “Hercules, Hercules” Aphid: Makes chewing sounds Honey Bee: Flaps arms and says “Bzzzzz” Lacewing: Flaps arms and hums House Wren: Flaps arms and whistles 3) Begin the game. Optional: Before full game begins, have each group start at different times, have Honey Bees begin first, followed by Aphids, Lacewings, Beetles, and then the House Wren. The University of Maryland Extension programs are open to any person and will not discriminate against anyone because of race, age, sex, color, sexual orientation, physical or mental disability, religion, ancestry, national origin, marital status, genetic information, political affiliation, and gender identity or expression. DRAFT 4) The first round should last approximately 2 minutes. After the first round, have students count how many pom-poms they have and how many are in each bucket (plant). Each plant needs at least 5 pom-poms and at least 1 piece of cloth (pollen) in order to survive. 5) Numbers of pom-poms that insects and house wrens need can vary, but here are some guidelines Plants: 5 pom-poms and 1 piece of pollen Honey Bees: 5 pom-poms per bee in the hive Aphids: 3 pom-poms each Lacewings: 5 pom-poms each House Wren: 10 pom-poms each Optional: Record the numbers of organisms left at the end of the round 6) For the following rounds, play the game with the numbers surviving plants and animals, or adjust the numbers in each group and play each round as a separate game. 7) Between each round, have students analyze the numbers and ask them if there is a way to shift the numbers that may result in the survival of more plants. 8) If desired, the instructor can allow students to switch roles (trade colored paper) and play the next round in a different role Debrief: 1) Ask students what they thought of the role that they were in. Was it easy? Difficult? Why? 2) Have students explain why their role was important, what did they do for the ecosystem? 3) If numbers were recorded at the end of each round, show students how populations were affected by one another. Sample Question: How did the number of pests at the start affect the number of plants at the end? 4) Have students describe how people can hurt/help insects in the ecosystem. Sample Question: How might killing aphids with pesticides affect lacewings, or honey bees? *Ecosystem: all of the connected components: non-living (abiotic), living (biotic), and manmade (cultural), that interact with one another in a particular area. Extensions: 1) After the activity, have students write a few words that describe their experience as an insect or bird. Have students compare based on what role they had. 2) Have students brainstorm about other insects or animals that could be put in the game. 3) Weather permitting: go outside and have students observe the insects, did they find pollinators, predators, decomposers and pests? Are there any insects they’d want more of around their school? How could they get them to come?
