2. How Plants Absorb Water

This experiment demonstrates how plants absorb water and how it moves through their roots to the leaves. It highlights the process of transpiration and capillary action.

Materials Needed: White flowers or celery stalks, food coloring, water, and a transparent jar.

Procedure:

• Place the flower or celery stalk in a jar of water mixed with food coloring.
• After a few hours or a day, observe the change in the color of the petals or leaves.

3. Water Filtration System

This Science Project Ideas for Class 8 involves building a simple water filtration system that mimics the process of water purification. You can explore how water passes through different materials to remove contaminants.

Materials Needed: Plastic bottles, sand, charcoal, cotton, gravel, and dirty water.

Procedure:

• Cut a plastic bottle in half and layer cotton, charcoal, sand, and gravel in it.
• Pour dirty water through the layers and observe how the filtration process works.

4. Build a Solar Oven

Demonstrate the use of solar energy to cook food. A solar oven uses sunlight to generate heat and cook food, making it a perfect example of renewable energy.

Materials Needed: Pizza box, aluminum foil, plastic wrap, black construction paper, tape, and a thermometer.

Procedure:

• Cut a flap in the pizza box and line it with aluminum foil.
• Place black construction paper at the bottom of the box to absorb heat.
• Cover the box with plastic wrap and place the food inside to see how it cooks.

5. The Effect of Acid Rain on Plant Growth

Explore the impact of acid rain on plants. This Science Project Ideas for Class 8 will allow students to understand how pollutants in the air affect plant health and growth.

Materials Needed: Small plants, different solutions (vinegar and water to simulate acid rain), and a measuring cup.

Procedure:

• Water plants with a mixture of vinegar and water (simulating acid rain) and observe the changes in their growth over time.
• Compare these results with plants watered with regular water.

6. Homemade Volcano

Create a simple volcano model to demonstrate an erupting volcano. This Science Project Ideas for Class 8 involves a chemical reaction between baking soda and vinegar that simulates a volcanic eruption.

Materials Needed: Baking soda, vinegar, plastic bottle, food coloring, clay or playdough.

Procedure:

• Build a volcano around a plastic bottle using clay.
• Add baking soda inside the bottle and pour vinegar to create an eruption.
• You can also add food coloring to make the eruption look more realistic.

7. Density Tower

This Science Project Ideas for Class 8 involves creating a liquid density tower where liquids of different densities are layered on top of each other, demonstrating how substances with different densities do not mix.

Materials Needed: Honey, dish soap, water, vegetable oil, rubbing alcohol, and a tall glass.

Procedure:

• Slowly pour different liquids into a glass, one at a time, without mixing them.
• Observe how they form distinct layers based on their densities.

8. Investigating Air Pressure

Explore the concept of air pressure by showing how air pressure can hold a piece of paper against gravity or even hold an object in place.

Materials Needed: A glass, a piece of cardboard, a small object, and water.

Procedure:

• Fill a glass with water and place a piece of cardboard over it.
• Quickly turn the glass upside down and hold the cardboard in place.
• Watch how the air pressure keeps the cardboard in place and the water from falling out.
