Example: Try different materials to see which conduct electricity and which are insulators. Use readily available items like coins (copper and other metals conduct, while plastic does not).
• Exploring Gravity: Drop different objects from the same height and observe how they fall. Explore concepts of gravity and air resistance. Example: Compare the rate of fall of a feather and a small ball. Explain how air resistance affects the feather's descent. Consider how this applies in different environments globally – thicker air at lower altitudes versus thinner air at higher altitudes.
• Creating a Lava Lamp: Combine water, vegetable oil, and food coloring in a bottle. Add an effervescent tablet (like Alka-Seltzer) to create a lava lamp effect. Explore concepts of density and convection. Example: Use different colored food colorings to observe the effect on convection currents.
• Building a Bottle Rocket: Use an empty plastic bottle, cork, water, and an air pump to launch a bottle rocket. Explore concepts of pressure and propulsion. Important Safety Note: Conduct this experiment outdoors in a large, open area and wear eye protection. Ensure the bottle is pointing away from people. Consider the impact of temperature on pressure within the bottle.

Chemistry Experiments

• Baking Soda and Vinegar Volcano: Combine baking soda and vinegar in a container to create a volcanic eruption. Explore concepts of chemical reactions and acids and bases. Example: Add dish soap to the mixture to create more foam. Vary the amounts of baking soda and vinegar to observe the impact on the reaction.
• Invisible Ink: Use lemon juice as invisible ink and heat to reveal the message. Explore concepts of oxidation and chemical changes. Example: Compare the effectiveness of lemon juice to other acidic substances like vinegar or orange juice.
• Growing Crystal Geodes: Dissolve borax in hot water and allow it to cool with pipe cleaners suspended in the solution. Explore the formation of crystals through supersaturation. Example: Use different colored pipe cleaners and observe the color of the crystals that form. Consider the effect of temperature on crystal growth rates.
• Testing pH Levels with Red Cabbage Indicator: Boil red cabbage and use the resulting liquid as a pH indicator. Observe color changes when mixed with different household substances (vinegar, baking soda solution, lemon juice). Example: Test common household items like soap, shampoo, and cleaning solutions. Research the pH scale and the chemical properties of acids and bases.

Biology Experiments

• Growing Bean Sprouts: Sprout bean seeds in a jar with moist paper towels. Observe the germination process and the growth of roots and shoots. Explore concepts of plant growth and development. Example: Compare the growth rate of beans in different conditions (light vs. dark, different temperatures, different amounts of water). Consider different bean varieties and their germination rates based on geographic origin.
• Observing Mold Growth: Leave a piece of bread exposed to air and observe the growth of mold. Explore concepts of fungi and decomposition. Example: Compare mold growth on different types of bread (whole wheat vs. white) or in different environments (warm vs. cold, humid vs. dry). Understand that the presence of certain molds (e.g., *Penicillium*) has historically led to important medical advancements.
• Extracting DNA from Strawberries: Mash strawberries and mix them with salt, water, and dish soap. Add rubbing alcohol to precipitate the DNA. Explore concepts of genetics and DNA structure. Example: Try this experiment with other fruits like bananas or kiwi.
