1. Testing Plant Growth with Different Liquids

This project involves exploring how various liquids affect plant growth. Fill several pots with soil, plant seeds, and water each pot with different liquids such as tap water, soda, juice, and other options. Over a few weeks, observe and record the growth rates and health of the plants to draw conclusions about which liquids promote better growth.

2. Investigating Temperature Effects on Chemical Reactions

In this experiment, you will mix baking soda and vinegar at varying temperatures to observe how temperature influences the intensity of the reaction. Measure the reaction’s fizzing and bubbling at different temperature points to understand the relationship between temperature and chemical activity.

3. Comparing Paper Towel Absorbency

This project tests how well different brands of paper towels absorb water. By dripping the same amount of water onto various brands and measuring the amount soaked up before breaking apart, you can determine which paper towel is the most absorbent, linking practical application with scientific inquiry.

4. The Impact of Light on Photosynthesis

In this experiment, you will test how different light sources (natural sunlight vs. artificial light) affect the rate of photosynthesis in plants. By measuring the growth and health of plants exposed to different light conditions, you can evaluate the best conditions for photosynthetic activity.

5. Measuring the pH of Various Household Liquids

This project involves testing the pH levels of common household liquids like vinegar, lemon juice, and baking soda solutions. By using pH strips or a pH meter, you can understand the acidity or alkalinity of these substances and how they compare to each other.
