Practical Experiments and Projects in CBSE Class 5 Science Textbook

1. Air and Water
- Experiment: Making a Rain Gauge
- This experiment teaches students how to make a simple rain gauge to measure rainfall.
- Materials required: A plastic bottle, a ruler, a funnel, and water.
- The experiment involves cutting the top off a plastic bottle and placing the funnel in the bottle to collect rainwater. The ruler is used to measure the collected water.
- Students can record rainfall data over a period of time and analyze the results.

2. Our Universe
- Experiment: Making a Solar System Model
- This experiment allows students to create a model of the solar system to understand the relative positions and sizes of the planets.
- Materials required: Polystyrene balls in different sizes, paint, string, and a cardboard or wooden base.
- Students can paint the polystyrene balls to represent the planets and attach them to the string in the correct order. The string can be suspended from the base to create a 3D model of the solar system.

3. Food and Digestion
- Experiment: Testing for Starch in Food
- This experiment helps students understand how to test for the presence of starch in different food items.
- Materials required: Iodine solution and various food items like potato, bread, rice, etc.
- Students can apply a few drops of iodine solution on the food items and observe any color change. The presence of starch is indicated by a blue-black color.

4. Safety and First Aid
- Project: Creating a First Aid Kit
- This project encourages students to create a first aid kit using simple household items.
- Students can identify essential first aid supplies such as bandages, antiseptic creams, adhesive tape, etc., and assemble them in a box or bag.
- They can also research and include information on how to administer basic first aid for common injuries like cuts, burns, and sprains.

5. Natural Resources
- Experiment: Testing Water for Impurities
- This experiment helps students understand the importance of clean water and how to test for impurities.
- Materials required: Water samples, filter paper, and a magnifying glass.
- Students can collect water samples from different sources and observe them using a magnifying glass. They can also filter the water samples and compare the clarity of filtered and unfiltered water.

These practical experiments and projects in the CBSE Class 5 Science textbook provide students with hands-on learning experiences and opportunities to apply their knowledge and skills. They enhance understanding, critical thinking, and scientific inquiry skills among students, making the learning process more engaging and interactive.
