Exploring Simple Machines: Lever

Title: Exploring Simple Machines: Lever

Compliance: Next Generation Science Standards (NGSS)

Subject: Industrial Arts

Summary: This first-grade activity introduces students to the concept of simple machines, specifically the lever, through hands-on exploration and experimentation.

Topic: Exploring Simple Machines: Lever

Learning Outcomes:

• Know what a lever is and how it works
• Understand the concept of effort and load in relation to levers
• Can identify and classify levers in everyday objects

Methodology:

This activity will be conducted in small groups to encourage collaboration and hands-on learning. Students will be provided with various materials to build and experiment with levers.

Resources/Materials:

• Wooden boards or rulers
• Pencils or dowels
• Small objects (e.g., toy cars, blocks)
• Books or weights
• Markers or stickers

Instructions:

1. Begin the activity by introducing the concept of levers to the students. Explain that a lever is a simple machine that helps us lift or move objects more easily.

2. Show examples of levers in everyday objects, such as a seesaw or a pair of scissors. Discuss how levers have a fulcrum, effort, and load.

3. Divide the students into small groups and provide each group with the materials listed above.

4. Instruct the students to build their own levers using the wooden boards or rulers as the base, pencils or dowels as the fulcrum, and small objects as the load.

5. Encourage the students to experiment with different positions of the fulcrum and load to observe how it affects the effort required to lift the load.

6. Once the students have built their levers, have them test the levers by placing different weights (books or weights) on the load side and observing how it moves.

7. After the experimentation, gather the students together for a discussion. Ask them to share their observations and discuss how the position of the fulcrum and load affected the effort required.

8. Finally, have the students identify and classify levers in everyday objects around the classroom or at home. They can use markers or stickers to label the levers they find.

Assessment:

To assess the students' understanding, observe their engagement during the activity and their ability to identify and classify levers. You can also ask them open-ended questions during the discussion to gauge their comprehension.

Additionally, you can provide a worksheet or drawing activity where students have to draw and label a lever they built during the activity.
