Inexpensive Science Experiments

Making science an entertaining subject for K-12 students means you’ll be using a lot of interactive teaching methods to get students involved and interested. Nowadays, our perception of science has moved from a lecture-intensive subject to one where you can teach more effectively by using a variety of hands-on learning methods to get your students active, motivated, and having fun. We know keeping an eye on supply expenses is important, so we’ve listed some inexpensive science experiments you can use in your classroom to help get you started and stay on budget.

Force and Motion Experiments

Before you can pull these three experiments off in your classroom, you’ll need to gather a few items first. You’ll want to find a few small cars, marbles, straws, balloons, and paper cups – items that can either be found around your home or at the local dollar store. You’ll also need an old game board.

Experiment 1

Create a ramp out of the game board, and place a book at the bottom of the ramp. Then, start rolling items down the ramp to measure them. You can use items as different as a car and a penny, measuring where they both land. Changing the angle of the ramp will also demonstrate an effect on force and motion.

Experiment 2

You can continue to experiment with Newton’s laws of force and motion by setting up a new ramp using a ruler and a book. Take one of the cups, cut an opening on one side, and place it at the bottom of the ramp. Roll marbles of different sizes and measure how far each marble pushes the cup along.

Experiment 3

Lastly, you can use the balloons and straws to make rockets. Thread a straw with a long piece of string you can stretch across your classroom from wall to wall. Then, blow up a balloon but don’t tie it. Tape it to the straw on one end of the classroom and let it go. The balloon will move across the string as the air blows out of it.


One great way to teach all three of these experiments is to let students split up into groups as you walk around and help them. Having them work together creates the opportunity for collaborative learning, and also makes these lessons more interactive and fun.
