 Lesson Plan STAGE 1: What Is Reproduction? Stage 1: In this set of lessons, students learn what is reproduction, and how the process works in both plants and animals. Students then learn about reproduction within cells. To show their understanding of the content in this stage, students will begin a project titled Zork Science where they will determine phenotypes and genotypes for a genetic simulation activity. Begin this stage by completing the welcome activity. Students will think about characteristics they share with their parents, and then upload drawings or photos of themselves with their parents. Lesson 1: Reproduction in Plants Objectives Task Descriptions Notes for Teacher Concepts Students learn about the six parts critical to plant reproduction. Students learn how plants use their physical appearance to attract pollinators that help them to reproduce. Warm-­‐up: With a partner, students consider how plant reproduction works. Afterwards, students discuss their ideas as a whole class. Check It Out: After viewing the parts of a plant in a diagram, students play the Life Cycles game to learn about plant parts, and answer questions in their notebook. Afterwards, students watch the Flower Reproduction video. Read and Discover: Students read about how flowers use different physical appearances to attract pollinators. Check It Out: Using what they learned in the previous Read and Discover activity, students play the Pick the Pollinator game where they match each plant with its pollinator. Bring It to Life: Students choose an animal, and then draw a picture of a fictional flower they think it would be best paired with. Students can look at online plant photos, or name ones they know. They can think about animals or insects that interact with the plants. In the class discussion, project an image of a plant, and have students share ideas. (Correct process provided after warm-­‐up.) Ask students to work in pairs as they go through the game. Students can take turns, as they complete the game. Also, encourage students to take the quiz one at a time afterwards, challenging them to get a high score. Check in with student pairs to ensure they are both participating. Ask students to look closely at the image and description to determine the pollinator. Have a few students share and discuss their drawings. Plants have special parts designed to help them reproduce. Pollinators help to pollinate plants, so that plants can reproduce. Flowers have different characteristics so that different pollinators will be attracted to them.

Lesson 2: Reproduction in Cells Objective Task Descriptions Notes for Teacher Concepts Students learn about how cells reproduce as they study the cell life cycle. Warm-­‐Up: After thinking about a situation where they have seen cells reproduce, students share their experiences. Read and Discover: Students read about how living things replicate cells. Specifically, students focus on skin cells, and then learn the cell life cycle. Check It Out: To learn about cell reproduction, students complete an interactive on mitosis. Now You Try: In the Eukaryotic Cell Cycle interactive, students click on phases to learn what happens in each step. Students play the Control of the Cell Cycle game to practice what they have learned about a cell’s life cycle. Share your own experience first to get students thinking (e.g., a scar you have, haircut, flowers in your yard). Have students quiz each other after they have gone over the interactive a few times. As students play the game, remind them to check back on the Eukaryotic Cell Cycle interactive as they need to. All living things are made of cells. Cells reproduce to replace cells that are constantly dying. Cells reproduce through a process called mitosis.

Lesson 3: Organism Multiplication Objective Task Descriptions Students learn about the two different types of reproduction (sexual and asexual) and why different organisms use different reproduction types. Warm-­‐Up: First, students look at pictures of parents and offspring and consider how alike and different they are. Then students list two examples of offspring identical to their parents, and two examples of offspring that have a mixture of traits from their parents. Check It Out: As students watch videos on sexual and asexual reproduction, they take structured notes in their notebooks. Read and Discover: Students read about reasons that different living things use either sexual or asexual reproduction. Students compare the types of reproduction, and are introduced to a Venn diagram. Bring It to Life: After taking a quiz to see what they have learned about reproduction types, students discuss with their partners or class why some animals or plants use asexual reproduction, sexual reproduction, or both. Notes for Teacher Give students a few examples to get started (e.g., human, puppy – both have mixtures of traits; starfish – identical to parent). Ask them if they think these examples are identical or a mixture of traits compared to parents. Have students share answers aloud after the whole class is ready. To start a discussion, have students consider reproduction in humans. Ask students to think about why it would be important for non-­‐identical humans to be born. Ask them to consider what the world would be like if humans reproduced asexually. Concepts Organisms reproduce either sexually or asexually. In sexual reproduction, organisms have two parents and genetic variety, but it is a slow process. In asexual reproduction, organisms have one parent and it is a fast process, but there is no genetic variety. In both reproduction types, organisms produce offspring, grow and develop, and use DNA. Key Vocabulary Offspring Sexual Asexual Genes Lesson Plan STAGE 1: What Is Reproduction? Team Project Objective Task Descriptions Notes for Teacher Concepts Students think critically about how parental traits in sexual reproduction can impact offspring. In their group, students discuss Spork and Vorki’s traits, deciding which ones their baby will have (table below). Then students draw a picture of how they think the baby will look.
