Cool And Amazing Science Fair Project Ideas

To get an A+ in the science fair: Choose among these 5 science projects: How fruits and vegetables ripen, oil slick, salt volcano, homemade barometer, and got gas.

The annual science fair is fast approaching. Surely you want to present something new and cool that would surely impress your science teachers and can help you earn a science ribbon. We offer you these some award-winning science projects that you might want to try.

How fruits and vegetables ripen

This experiment aims to tackle the different factors that can affect the rate a fruit or vegetable ripen. Discuss how temperature, light, exposure to other ripened fruits and placing in containing can help aid the ripening process.

Oil slick

This experiment aims to know which materials can effectively clean an oil spill. Fill a bowl with water and add a few tablespoons of oil. See which materials are effective in removing the oil in water. You can use cotton, a gauze then a polypropylene cloth. You can see that the polypropylene cloth is the most effective since it a similar chemical composition with oil. Because of this, they are attracted to each other. Give some insights after the demonstration like how you can give ways in helping clean up oil spills and some insights on the different oil leak disasters in history.

Salt volcano

Make your own lava lamp. Pour about 3 inches of water in a glass then add about 1/3 cup of cooking oil. Observe for reactions in each step. Add a drop of food coloring next. Then shake some salt over the solution. Explain to the class why does oil float on water, then what happens if the salt if dissolved in the water after passing through the layer of oil. To finish it, explain why this experiment resembles to how a lava lamp functions.

Homemade barometer

If you are fond of meteorology, you can make your own barometer to help predict weather at home. Fill a measuring cup with dyed water. Place an empty soda bottle upside down into the cup. Find a bottle that fits the mouth of the cup without touching it’s bottom. Make sure that the water level reaches the neck of the bottle. Make a mark on the cup to indicate the water level inside the bottle then observe for a few days. After, explain how the air pressure affects the contents of the bottle to class.

Got gas

This experiment aims to break down water into Hydrogen and Oxygen. Sharpen both ends of 2 pencils removing the erasers or any metal parts. Fill a jar with water then cover with cardboard then tape it. Insert the one pencil through the cardboard then do the same with the other one 3 cms away. Make sure the both pencil leads are of the same level in the water. Using a wire, connect the one of one pencil to the negative terminal of a lamp battery and the other one on the positive. Observe for bubbles at the pencil leads inside the jar. Afterward, give explanation to this chemical change.

Be confident in your presentation. After choosing the right concept then partnered with a comprehensive explanation, that science ribbon would be yours.
