**Lesson Plan: Energy and Motion**
**Grade Level:** 4th Grade
**Subject:** Science
**Duration:** 60 minutes
**Lesson Topic:** Energy and Motion
**Standards Addressed:**
- NGSS 4-PS3-1: Use evidence to construct an explanation relating the speed of an object to the energy of that object.
- NGSS 4-PS3-3: Ask questions and predict outcomes about the changes in energy that occur when objects collide.
**Objectives:**
Students will be able to:
1. Define energy and motion.
2. Explain the relationship between energy and motion.
3. Observe and record information from a simple experiment to determine how energy affects motion.

### Materials:
- Chart paper and markers
- Toy cars (enough for small groups)
- Ramps (books or blocks to create ramps at different heights)
- Measuring tape
- Stopwatches
- Notebooks or lab sheets for recording observations
- Video clips/animations showing different forms of energy
### Lesson Structure:
**1. Introduction (10 Minutes)**
- Begin with a brief discussion to activate prior knowledge. Ask students: "What do you know about energy and motion?"
- Show a short video or animation (3-5 minutes) that illustrates different types of energy (such as kinetic and potential energy) and how they can affect motion.
**2. Instruction (15 Minutes)**
- Define key terms: energy, motion, kinetic energy, potential energy.
- Explain that energy can be stored (as potential energy) or in use (as kinetic energy).
- Introduce the concept that the speed of an object can change depending on the amount of energy it has.
- Use examples like a roller coaster at the top of a hill (high potential energy) speeding down (transferring to kinetic energy).
**3. Interactive Activity (25 Minutes)**
- **Experiment: How Height Affects Speed**
1. Divide students into small groups.
2. Give each group a toy car, a ramp, measuring tape, and a stopwatch.
3. Instruct each group to set up their ramps at different heights (e.g., using 1, 2, and 3 books).
4. Each group will release the car from the top of the ramp, measure the distance traveled, and time it.
5. Students should record their observations: ramp height, time taken, and distance traveled.
6. Have each group repeat the experiment three times for accuracy.
**4. Analysis (5 Minutes)**
- Allow groups to share their findings.
- As a class, discuss the results. Did the car travel faster and further from a higher ramp? Why do you think that happened?
- Guide students to understand that higher ramps give the car more potential energy, which converts to more kinetic energy and thus faster motion.
**5. Conclusion and Reflection (5 Minutes)**
- Summarize the key points:
- Energy can be stored as potential energy.
- When an object moves, potential energy converts to kinetic energy.
- More energy results in faster motion.
- Ask students to reflect in their notebooks or lab sheets: "What new thing did I learn about energy and motion today?"
**6. Homework/Extension Activity**
- Ask students to find examples at home where they see energy converting from one form to another. They can draw pictures or write a short description.
### Evaluation:
- Formative Assessment: Observe student participation during discussions and group activities, and look at their recorded observations for understanding.
- Summative Assessment: Review reflections and the homework assignment to assess comprehension of concepts.
**Teacher Notes:**
- Ensure safety during the experiment, especially with ramp setup.
- Have additional ramps or materials in case of technical difficulties with the initial setup.
- Adjust the complexity of the experiment based on the students' understanding and needs.
