Cool Science Fair Projects Intro

If you’re planning to do cool Science Fair Projects this year, use more than just a light bulb and a 6-volt battery. There are lots of other great ideas or cool Science Fair Projects out there. Many projects are suitable for distinct grades based on your curiosity. The eighth grade is a great time to start working on your science fair project. We’ve gathered some cool science fair projects you can try in the classroom. Teachers can find ideas, too, with hands-on activities and experiments that kids can do. These activities will help kids learn about science and the world around them.

1. Citric Acid and Baking Soda Volcano

You can use lemon and baking soda for this experiment. Take a large size lemon and cut it from the top. You can use any food color to lay over the lemon. Throw the baking soda and wait for the chemical reaction with the lemon’s citric acid. The result is a colored volcanic eruption. It is colored because you used the food color.

2. Shine the pennies

If you are looking for an easy-to-do, cool science fair project, shining the pennies is the one. You can soak dirty and tarnished pennies in different acids (vinegar, salsa, lime juice, and lemon juice). See which ones shine the most. Take notes on which acid worked best to make the pennies shiny.

3. Explore density with salt

This lava lamp experiment is a fun way for kids to learn about the density of liquids. You can use materials that you have right in your kitchen to do this experiment. These are water, glass, salt, food coloring, and vegetable oil. Fill the clear glass with water, 2/3 portion. Now pour some vegetable oil and see what happens. It will float over water. Pour a few drops of food color. Sprinkle sale and wait for the results.

4. Rainbow Rubber Eggs

Place an egg dipped in vinegar in a glass or jar and pour a few drops of food color. Wait for a few days, 4-5 days. It will turn into a rubber ball-type material. The egg will bounce and feel like rubber. However, it can break if you exert more force on it or throw it at the wall. This experiment is one of the cool science fair projects that are easy to do. Nevertheless very exciting.

5. Magical Rollback Cans

This cool science fair project sheds light on physics concepts. It is the difference between kinetic energy and potential. Use a coffee can or any other soft drink can. Make a hole at the top and the bottom with a nail. Tape a rubber band at the top of a nut. Open the paper clip and hook it onto the rubber band. Thread the rubber band through the bottom hole and secure it with a paper clip. You can use a pencil to stretch and hold a rubber band. Thread the rubberband through the hole in the lid and secure it with a paper clip. Roll the can on the floor, and it will roll back.

6. Density Tower

The concept is to layer different types of dense liquids over each other. Fill the jars with different liquids to see what happens. For example, pour water into a glass. Then pour honey over it, then vegetable oil, and so on. All the liquids will form layers according to their density. You can create two or three jars to show up at the science fair.

7. Magic Magnets

The magic of magnets never stops to excite students. So, you will require three or four magnets. Using wooden sticks, you can create a platform to hang a circular object attracted to a magnet with a string. Place two or more magnets under this object and see the result. You can also use a single magnet to move around the object.

8. Lemon Battery Power

You can make a battery with five or six large-size lemons. It will be surprising for other students to find out about this. Surely, they missed this cool science experiment. You will need copper wires, lemons, galvanized nails, alligator clips, a voltmeter, and wire cutters. Place copper wire and nails in the lemons and measure voltage. Roll the copper wire on the galvanized nails and use it for each lemon. Join all the lemons together using the copper wires attached to the nails. Check the voltmeter for a surprise.

9. Epsom Salt Crystals

You will require Epsom salt, a jar, water, food coloring, a measuring cup, and a spoon. Pour a cup of Epsom salt into the jar. Add a cup of hot water. Stir for one to two minutes until the salt dissolves. You can add food color if you want to. Mix well with the color. Drop a few grains of sand into the jar. Leave it inside the fridge overnight. It is how you can grow Epsom salt crystals for cool science fair project.
