Sure! Here’s a structured breakdown of the experiments you've listed, including materials used, their classification as physical or chemical experiments (Por C), and two pieces of evidence for each:
1. Monster Foam
- Experiment: Monster Foam
- Materials Used: Hydrogen peroxide (H₂O₂), soap, neurotoxin (e.g., food coloring or another agent).
- Por C: Chemical
- 2 Pieces of Evidence:
- The catalytic decomposition of hydrogen peroxide is accelerated by soap, producing oxygen gas and foam.
- The reaction shows a visual transformation of materials (liquid to foam), indicative of a chemical change.
2. Mentos and Diet Coke
- Experiment: Mentos and Diet Coke Eruption
- Materials Used: Mentos candies, Diet Coke (or similar carbonated beverage).
- Por C: Physical
- 2 Pieces of Evidence:
- The rapid release of carbon dioxide gas from the soda leads to a dramatic eruption, a physical reaction.
- The process does not alter the chemical composition of the Diet Coke; it simply releases gases already present under pressure.
3. Changing Your Voice
- Experiment: Changing Your Voice (Using different materials to modify sound).
- Materials Used: Voice, tubes/microphones, possibly filters or devices (like a vocoder).
- Por C: Physical
- 2 Pieces of Evidence:
- Sound waves are manipulated through physical changes (e.g., pitch and frequency alterations) without changing the fundamental voice production processes.
- The experimental outcomes (different sound qualities) reflect variations in physical properties of sound waves rather than chemical changes.
4. Grow Creatures
- Experiment: Grow Creatures (often refers to expanding toys or gels that grow when placed in water).
- Materials Used: Polymer-based creatures (e.g., water-absorbing toys).
- Por C: Physical
- 2 Pieces of Evidence:
- The creature expands and increases in size as it absorbs water, indicating a physical change due to hydration.
- The material does not undergo a chemical transformation; it simply changes state and size when in contact with water.
5. Glow Sticks
- Experiment: Glow Sticks
- Materials Used: Chemicals in glow stick, usually hydrogen peroxide, phenyl oxalate ester, and a fluorescent dye.
- Por C: Chemical
- 2 Pieces of Evidence:
- The glow sticks produce light through a chemiluminescent reaction, a definitive indicator of a chemical reaction.
- The reaction is irreversible; once the glow stick is activated, the chemical components change and produce light.
6. Oozing Pumpkins
- Experiment: Oozing Pumpkins (often involves baking soda and vinegar in decoration).
- Materials Used: Baking soda, vinegar, food coloring (for visual effect).
- Por C: Chemical
- 2 Pieces of Evidence:
- The reaction between baking soda (a base) and vinegar (an acid) produces carbon dioxide gas, shown by bubbling and fizzing.
- The visual transformation (from solid and liquid materials to gas and foam) indicates a chemical change.
