1. Build a Model of the Solar System:
- Create a scaled model of the solar system, including the planets, moons, and the Sun.
- Use different materials to represent each celestial body and accurately depict their relative sizes and distances.
2. Investigate Plant Growth Factors:
- Design an experiment to study how different factors (such as light, water, nutrients, temperature, etc.) affect the growth of plants.
- Use a controlled environment to manipulate the variables and measure plant growth.
3. Explore Water Quality:
- Collect water samples from different sources (e.g., tap water, river water, pond water) and test their quality parameters.
- Use chemical and biological tests to measure pH, dissolved oxygen, nitrates, phosphates, and microbial contamination.
4. Build a Simple Robot:
- Design and construct a basic robot using motors, sensors, and a microcontroller.
- Program the robot to perform simple tasks, such as moving in different directions or responding to light and sound.
5. Investigate Alternative Energy Sources:
- Research and compare different renewable energy sources, such as solar, wind, hydropower, and biomass.
- Build a small-scale prototype or model to demonstrate how these energy sources work.
6. Study Air Pollution:
- Measure the levels of air pollutants (e.g., PM2.5, PM10, NO2, SO2) in your local environment using an air quality monitoring device.
- Analyze the data and identify potential sources of pollution.
7. Investigate the Properties of Different Materials:
- Test and compare the properties of various materials (e.g., metals, plastics, fabrics) in terms of their strength, density, conductivity, thermal expansion, etc.
- Use appropriate instruments and techniques to conduct the experiments.
8. Design a Water Filter:
- Develop a prototype of a water filter using locally available materials.
- Test the effectiveness of the filter in removing impurities and contaminants from water.
9. Explore Genetics and Heredity:
- Study genetic inheritance patterns using Punnett squares or simulations.
- Analyze the role of genes in determining traits and variations within a population.
10. Investigate the Physics of Motion:
- Design experiments to study the concepts of motion, such as uniform motion, accelerated motion, projectile motion, and Newton's laws of motion.
- Use sensors, timers, and data analysis to measure and analyze motion.
