Objective

By the end of this lesson, the student will understand the concepts of gravity and acceleration, and they will create a protective method to keep a hard-boiled egg from cracking when dropped. This will help them learn about forces and how to apply creative problem-solving skills.

Materials and Prep

• 1 hard-boiled egg
• Open space to drop the egg
• Measuring tape (optional for height measurement)
• Notebook and pencil for observations

Before the lesson, make sure the egg is hard-boiled and cooled down. Explain to the student that they will be working with gravity, which pulls everything down towards the Earth, and acceleration, which is how fast something is moving when it falls.

Activities

• Gravity Experiment:

  Start by discussing what gravity is and how it affects the egg. Have the student hold the egg at different heights and drop it to observe what happens. Ask them to think about how the height affects the egg's fall.

• Protective Design Challenge:

  Now, challenge the student to come up with a way to protect the egg from cracking. They can think about shapes, cushioning, or barriers. Let them sketch their ideas in the notebook.

• Drop Test:

  Once they have a design, it's time for the drop test! Have the student drop their protected egg from a height (like a table or a chair) and see if it survives. Discuss the results and what could be improved.

Talking Points

• "Do you know what gravity is? It's the force that pulls everything towards the ground!"
• "When we drop the egg, it falls because of gravity. Can you guess what will happen if we drop it from higher up?"
• "Acceleration means how fast something is going. The egg speeds up as it falls, right?"
• "What do you think we can do to protect our egg? Let's think about soft materials or shapes!"
• "After we drop the egg, we will see if our ideas worked. What do you think we can learn from this?"
• "Why do you think some things break when they hit the ground? It's all about how fast they fall!"
• "Let's draw our designs! What shape do you think will help the egg the most?"
• "Every time we test something, we can learn and make it better next time. What will you change for the next drop?"
