How does the light change when it passes through certain objects?

To find out if different types of coke affect the size of the explosion caused by a chemical reaction when the mentos drops into coke.

1. Objective:

   . To find out if the distance of the light source and the object affects the size of the shadow cast on the screen.

2. Materials Needed:

   • Light Source: Flashlight, lamp, or sunlight.

   • Opaque Objects: Book, ball, toy, etc.

   • Screen/Surface: White paper, wall, or cardboard for shadow projection.

   • Measuring Tools: Ruler or tape measure (optional for precise measurements).

   • Optional: Color filters, translucent objects, or varying light intensities.

3. Setup:

   • Position the light source at different distances and angles.

   • Place the object between the light and the screen.

   • Ensure the screen is flat for clear shadow projection.

4. Variables to Test:

   • Distance between light and object.

   • Size of Object.

   • Light Source Angle.

   • Transparency of Object (opaque, translucent, transparent).

5. Observation and Data Collection:

   • Record shadow size, shape, and intensity.

   • Note how variables like light position or object size impact the shadow.

6. Conclusions: Analyze how factors like light distance or angle affect shadow characteristics and how object size or material influences shadow sharpness

   This is what i think is good for a light and shadows experiment

• Observe how a cell reacts to different substances.
