**Lesson Plan: Forces and Motion**
**Grade Level:** 3rd Grade
**Subject:** Science
**Topic:** Forces and Motion
**Duration:** 1 hour
**Learning Objectives:**
1. Students will understand what a force is and how it impacts motion.
2. Students will be able to identify and describe different types of forces (push, pull, gravity, and friction).
3. Students will engage in simple experiments to observe forces in action.
**Materials Needed:**
- Toy cars
- Ramps (books or boards to create different inclines)
- Marbles
- String
- Magnets
- Paper
- Pencils
- Chart paper
- Markers
**Standards:**
- NGSS 3-PS2-1: Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.
**Procedure:**
1. **Introduction (10 minutes):**
- Begin with a short discussion to engage students. Ask questions like:
- What do you think force means?
- Can you give examples of when you’ve used a force (like pushing or pulling)?
- Define key terms: force, push, pull, gravity, friction.
2. **Direct Instruction (15 minutes):**
- Use chart paper to visualize and explain:
- **Push and Pull:** Demonstrate with an object (e.g., pushing a book across a table).
- **Gravity:** Explain gravity as a force that pulls objects toward the Earth. Drop different objects to observe how they fall.
- **Friction:** Demonstrate with different surfaces (e.g., a toy car on carpet vs. tile).
- Show videos or animations that illustrate these concepts.
3. **Guided Practice (20 minutes):**
- Divide students into small groups and distribute materials.
- Set up stations for different activities:
- **Station 1:** Rolling toy cars down ramps (different inclines) to observe push and pull.
- **Station 2:** Dropping different objects to observe gravity.
- **Station 3:** Using different surfaces to push toy cars and feel the effect of friction.
- **Station 4:** Using magnets to show push and pull forces.
- Have students rotate through each station, spending about 4-5 minutes at each. Encourage them to make observations and discuss within their groups.
4. **Independent Practice (10 minutes):**
- Students will choose one of the experiments they found most interesting and draw a picture of it, including labels and a brief explanation of what they observed.
- Provide worksheets with prompts to guide their explanations, such as “I noticed the car moved faster on ______ because _____.”
5. **Closure (5 minutes):**
- Gather students for a group discussion.
- Ask guiding questions to review what they’ve learned:
- What did you notice about the way objects move on different surfaces?
- How did gravity affect the objects you dropped?
- What was your favorite experiment and why?
- Summarize key points about forces and motions.
6. **Assessment:**
- Observe students during group activities and discussions to assess understanding.
- Review students' drawings and explanations to check for comprehension.
- Ask students to share one new thing they learned about forces and motion.
**Extension Activity:**
- Students can create a simple experiment at home using household items to demonstrate force and motion and share their findings with the class.
**Homework:**
- Write or draw about a real-life example of forces and motion (e.g., playing soccer, riding a bike).
