10 SCIENCE FAIRS IDEAS FOR STUDENTS WITH PROCESS:
1. Baking Soda and Vinegar Volcano:
Procedure:
- Create a volcano shape using clay or paper mache.
- Place a small container at the top of the volcano to hold the ingredients.
- Pour vinegar into the container.
- Add a few drops of food coloring and dish soap for visual effects.
- Slowly pour baking soda into the container and observe the eruption.
2. Eggshell Strength Experiment:
Procedure:
- Collect empty eggshells and clean them thoroughly.
- Divide the shells into different groups.
- Soak some eggshells in vinegar to dissolve the calcium carbonate.
- Place some eggshells in water or other liquids like soda or juice.
- Observe and compare the changes in the eggshells over time to test their strength.
3. Lemon Battery:
Procedure:
- Gather a lemon, copper nail, zinc-coated nail, and wires with alligator clips.
- Insert the copper nail and zinc-coated nail into the lemon, keeping them apart.
- Connect the copper nail to the positive end of a voltmeter using a wire and alligator clip.
- Connect the zinc-coated nail to the negative end of the voltmeter.
- Measure and record the voltage produced by the lemon battery.
4. Chromatography: Separation of Pigments:
Procedure:
- Take a coffee filter paper and draw a small dot of different colored markers near the bottom.
- Dip the bottom of the filter paper into a cup of water, ensuring the dot is above the water.
- Allow the water to move up the filter paper through capillary action.
- Observe the separation of pigments as the water travels up and record the results.
5. Effect of Music on Plant Growth:
Procedure:
- Select several plants of the same species and size.
- Place each plant in a separate container.
- Play different genres of music near each plant for a certain duration every day.
- Measure and record the growth of each plant over a specified period.
- Compare the growth of plants exposed to different types of music.
6. Making a Homemade Lava Lamp:
Procedure:
- Fill a clear container with water, leaving some space at the top.
- Add vegetable oil to the container, filling it almost to the brim.
- Add a few drops of food coloring and observe how it stays in the oil.
- Drop an effervescent tablet into the container and observe the colorful bubbles rising and sinking.
7. Potato Battery:
Procedure:
- Insert two different metal electrodes (e.g., copper and zinc) into a potato.
- Connect a wire from each electrode to a small light bulb or LED.
- Observe if the bulb lights up and measure the brightness.
- Compare different combinations of electrodes to determine which produces the highest voltage.
8. Fruit Ripening:
Procedure:
- Gather a selection of unripe fruits (e.g., bananas, avocados, tomatoes).
- Place each fruit in a different environment (e.g., room temperature, refrigerator, paper bag).
- Monitor and record the time it takes for each fruit to ripen.
- Analyze and compare the effects of different environments on fruit ripening.
9. Baking Soda and Vinegar Reaction:
Procedure:
- Mix baking soda and vinegar in a container and observe the reaction.
- Measure the volume of gas produced or record the time it takes for the reaction to complete.
- Vary the ratios of baking soda and vinegar to investigate how it affects the reaction.
- Compare the reaction with different acids or bases.
10. Solar Still:
Procedure:
- Construct a simple solar still using a clear plastic container and a smaller container placed inside it.
- Add water to the larger container and cover it with plastic wrap, leaving a small depression in the middle.
- Place a weight in the center of the plastic wrap, directly above the smaller container.
- Leave the solar still in direct sunlight and observe the condensation of water inside the smaller container.
12. Water Filtration:
Procedure:
- Design and construct a water filtration system using readily available materials (e.g., gravel, sand, activated charcoal).
- Pour water contaminated with impurities (e.g., dirt, food coloring) through the filtration system.
- Collect and analyze the filtered water to determine its clarity and purity.
- Compare the effectiveness of different filtration materials and methods.
13. Magnetic Levitation:
Procedure:
- Build a simple magnetic levitation system using magnets and a conductive material, such as aluminum foil or copper wire.
- Place the conductive material above the magnets and observe its levitation.
- Adjust the distance, angle, or arrangement of magnets to investigate their effects on levitation.
- Measure and record the stability and height of levitation.
10. Density Tower:
Procedure:
- Collect liquids with different densities, such as water, oil, and syrup.
- Carefully layer the liquids in a transparent container, starting with the densest liquid at the bottom.
- Observe the formation of distinct layers and record the order and thickness of each layer.
- Experiment with additional liquids or substances to create a more complex density tower.
