2. Observe how they layer based on their density.

Learning Outcome:
Students learn about liquid density and how it determines the behavior of different substances.

9. Egg Drop Challenge

This physics-based project ranks high among science project ideas for teaching concepts like gravity and force.

Materials Needed:

• Raw eggs
• Bubble wrap, cotton balls, and other cushioning materials

Steps:

1. Wrap the egg in protective material.
2. Drop it from a height and see if it stays unbroken.

Learning Outcome:
Students learn about impact, force, and cushioning in this classic physics experiment.

10. Homemade Weather Station

For environmental science project ideas, a homemade weather station allows students to measure weather patterns.

Materials Needed:

• Plastic cups, ruler, paper for rain gauge
• Thermometer

Steps:
