Full lesson	Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle}

Lesson Plan

Topic

3.PS3: Energy

Recognize that energy is present when objects move; describe the effects of energy transfer from one object to another.
Apply scientific ideas to design, test, and refine a device that converts electrical energy to another form of energy, using open or closed simple circuits.
Evaluate how magnets cause changes in the motion and position of objects, even when the objects are not touching the magnet.

Objectives

Students will recognize and describe energy present in moving objects.
Students will design, test, and refine a device that converts electrical energy to another form of energy.
Students will evaluate the effect of magnets on the motion and position of objects.

Materials

Magnets (various sizes)
Small toy cars
Battery-operated fans or simple circuit kits
Paper and pencils for sketching designs
Timer or stopwatch
Worksheets for documentation

National Curriculum Alignment

This lesson aligns with the Next Generation Science Standards (NGSS) for third grade.

Lesson Structure

Step Number	Step Title	Length (minutes)	Details
1	Introduction	5	Briefly introduce the concept of energy. Use everyday examples (e.g., moving objects).
2	Energy Transfer	10	Conduct a demonstration by rolling toy cars and discussing energy transfer. Capture students' observations.
3	Designing Devices	10	Have students work in pairs to design a simple device to convert electrical energy into motion. Provide materials.
4	Testing & Refining	5	Students test their designs and make improvements. Encourage collaboration and sharing of ideas.
5	Evaluating Magnets	5	Explore how magnets can affect the motion of objects without touching them. Provide hands-on activities with magnets.
6	Conclusion	5	Recap key concepts learned about energy and magnets. Inform students about homework assignments.

Homework

Students will complete a worksheet documenting their design process and reflections on energy transfer using a simple circuit. The worksheets should be submitted the next class without any formal presentation.
