Vast collection of science project ideas on popular science fair topics ranging from physics and chemistry to biology and even sociology.

Here are science fair ideas suitable for every grade level, be it preschool, kindergarten, elementary school, middle school, or high school.

Energy comes in many forms. Electric energy can be converted into useful, or mechanical energy, by machines called electric motors.

Make this simple electric motor under 4 simple steps.

1.Starting in the center of the wire, wrap the wire tightly and neatly around the marker 30 times

2.Thread each loose end of the wire coil through the large eye of a needle. Try to keep the coil as straight as possible without bending the wire ends.

3. Lay the D battery sideways on a flat surface

4. Stick some modeling clay on either side of the battery so it does not roll away

5. Tape the small magnet to the side of the battery so that it is centered underneath the coil.

Inflate a Balloon Using Baking Soda and Vinegar

Students learn about gas and chemical reactions by discovering how to inflate a balloon using baking soda and vinegar. This place will help harmful helium balloons.

Here, are 4 amazing steps to make inflated balloons

  1. Using the funnel, add the baking soda to each balloon.
  2. Pour the vinegar into the bottle.
  3. Carefully fit the balloon over the bottle opening.
  4. Once the balloon is fitted snugly on the nozzle, hold up the balloon and allow the baking soda to fall into the vinegar.

  2. Fill the plastic bottle ¾ full with vegetable oil.
  3. Add water to the neck of the bottle, leaving a little space between the water line and the top of the container.
  4. Decide on a color for your ‘lava lamp’ bottle. Select the food coloring accordingly.
  5. Add 10 or more drops of food coloring to the bottle until a rich color is seen.
  6. Break the Alka-Seltzer tablet into smaller pieces (6 to 8). Add one piece at a time observing each reaction.
  7. When the bubbling stops replace the bottle cap.
  8. Tip the bottle back and forth and observe the reaction. Tip, twist, and shake the bottle in different directions. Observe the reactions and take notes.
