You will set up multiple pots with the same type of plant and expose each to a different light source. Measure the plants’ growth over a few weeks and compare the results. This will highlight the importance of light in photosynthesis.
2. Exploring the pH Levels of Common Household Liquids
Investigate how the pH levels of everyday liquids, like lemon juice, vinegar, and baking soda solutions, affect their properties and reactions. Using pH strips, measure and record the pH of each liquid, then perform simple reactions, like mixing them with baking soda, to observe changes. This experiment will demonstrate the role of acidity and alkalinity in chemical reactions.
3. Investigating the Impact of Temperature on Yeast Fermentation
In this project, you’ll explore how varying temperatures influence the rate of fermentation in yeast. Set up several flasks with a sugar-water solution and yeast, then incubate them at different temperatures. Measure the amount of carbon dioxide produced over time to determine the optimal temperature for fermentation, showcasing how temperature affects biological processes.
4. The Science of Homemade Batteries
Create simple batteries using common materials like lemon juice, copper coins, and galvanized nails. This project will demonstrate how chemical reactions can produce electricity. Assemble your batteries, measure the voltage produced with a multimeter, and discuss the science behind how they work, emphasizing the role of electrolytes in generating electrical energy.
5. Examining the Relationship Between Sugar Intake and Energy Levels
This project investigates how varying sugar intake affects energy levels. Recruit participants to consume different amounts of sugar and monitor their energy levels through self-reported surveys or simple physical activities. Analyze the data to determine trends and draw conclusions about how sugar consumption impacts energy, providing insights into nutrition.
6. Creating a Water Filtration System
Design and construct a simple water filtration system using sand, gravel, and activated charcoal to purify dirty water. Test the water quality before and after filtration using basic water testing kits. This project illustrates the principles of filtration and the importance of clean water for health.
7. The Effect of Music on Plant Growth
