Matter with Moxie Unit 4th Grade Science Rebecca Cadeau Lesson #6 Common Core Standard: o P.EN.E.5 Electrical Circuits - Electrical circuits transfer electrical energy and produce magnetic fields. P.EN.04.51 Demonstrate magnetic effects in a simple electrical circuit. I Can Statement: o I can show how magnets are effected by a simple electrical circuit. Materials: o https://www.brainpop.com/science/energy/electromagnets/ o https://www.youtube.com/watch?v=Ci2623r-nb0 o http://www.harcourtschool.com/activity/electromagnets/ o Electromagnet materials o Electromagnet Investigation booklet o Electromagnet Reading o Powerpoint Preparation: o Cue up PowerPoint and videos/ activity o Make copies of reading and booklets o Prepare electromagnet materials Prior Knowledge: o Energy definition o Knowledge of electricity as form of energy New Vocabulary/Ideas: o Circuits o Transfer of energy through circuits o Protons/neutrons/electrons o Electromagnet Lesson Plan: Focus Lesson o Anticipatory Set: Show students a Brainpop video on electromagnets. Have o o o Productive Group Work & Guided Instruction o o students watch the video and then let them know that today they will be learning about electromagnets and learning about how they are used. https://www.brainpop.com/science/energy/electromagnets/ Value/Purpose: to show how electricity can be used to create magnets Today we are talking about electromagnets and how we can use a simple electric circuit to create a magnet! Show students the materials (in the PowerPoint) and ask them how they think that these materials will be used to make a magnet. Have students turn and talk to make a prediction for how the materials will be Matter with Moxie Unit (can be separate or together) o o o o o o o o Independent Learning o o o o 4th Grade Science Rebecca Cadeau used to make a magnet. Have students fill out the prediction section of their electromagnet investigation booklet. Show students the youtube video on how to make an electromagnet or demonstrate with actual materials, if available. Explain to students how these materials work together to create magnetism and pick up metal objects, just like a regular magnet. Tell students that they will be completing an activity to determine how to change the strength of an electromagnet and how different variables affect the strength. Use the harcourt electromagnet activity to demonstrate that the amount of wire and batteries will affect how strong the magnet is. As you are going through the activity have students record the observations in their electromagnetic investigation data table. Have students take turns or vote on what to do in the activity (how many batteries or wires to add or take away) in order to pick up the correct amount of paper clips. Go through a couple examples with the students until you feel they understand the concept. After going through the activity have students write their observations in their booklets and draw a picture of an electromagnet Have students read the Electromagnets reading independently. After students have read show them the parking lot exit slip for the day and have them write their answer on a sticky note and place it in the parking lot next to their number. Parking Lot Exit Slip: What do you need to do to make a strong electromagnet? Close the lesson by restating the object and reviewing how to make an electromagnet. Assessment: o Formative assessment: Turn and talks, Electromagnet Investigation booklet, parking lot exit slip o Summative assessment: Matter w/ Moxie assessment. Higher Order Thinking: o Kids will be connecting and synthesizing knowledge about matter with new knowledge about electromagnets. Differentiation: o Above- Students who are more advanced will be given extra readings to apply their knowledge and asked deeper questions to guide their thinking. They may be asked to try and think of how an electromagnet is used in their everyday lives and how an electromagnet differs from a normal magnet that we have previously learned about. o Below- Students who are struggling with the lesson will be given extra practice and will be able to read with a partner. They will also be able to work with the teacher in a small group setting to get more individualized instruction. Reflection: o How well did the students respond/perform to the lesson? Students were very engaged in this lesson. In the beginning they were a little unfocused and it took a little while for them to really engage with the lesson. During the harcourt online electromagnet activity students were very engaged. They loved that they were able to manipulate the coil and Matter with Moxie Unit 4th Grade Science Rebecca Cadeau amount of batteries to change the strength of the electromagnet. Some students even figured out the math to make the perfect electromagnet on the first try. Other students just understood that the more wire that is wrapped around the nail the more strength the electromagnet has, which is what the goal of this activity was. o Were students able to understand what an electromagnet was and how to create one? Yes, students understood that an electromagnet can be created using a nail, copper wire and a battery. They also understood that depending on how much coil and batteries are used the strength of the magnet will be affected. This was evident in their parking lot exit slip responses and all students knew the correct materials needed to make an electromagnet. o What will I need to change to future lessons based on the students understanding and performance during this lesson? I will definitely try to find more engaging activities that students can participate in like this one. Students were engaged and learning about this new concept and it was evident that they understood the concept based on the activities that were done to show their learning.
