Are you studying the scientific ideas behind various forms of energy in your classes? Do you want to conduct hands-on activities with your kids to bring your energy lessons to life? Why not consider including some Energy Science Experiments in your lesson plan?
Using experiments, you may genuinely involve your kids in understanding various types of energy. It allows learners to engage and participate in the course, adding an interactive component.
Potential and Elastic Energy
1. Rubber Band Stretching
Rubber bands are great illustrators of elastic energy because of their extensibility. Students participate in this exercise by stretching and releasing rubber bands to observe the correlation between the amount of strain and the subsequent distance traveled by the band.

4. Catapult made on popsicle sticks
Elementary grade level kids construct a basic catapult in this exercise using recyclable materials, craft sticks, and rubber bands. When you push down on the launching stick, it stores up potential energy, much like an elastic band would do when you stretch it. The energy stored in the stick is transformed into kinetic energy when it is released.

5. Chain Reaction of Popsicle Sticks
Learners gently weave wooden sticks together in this project, ensuring each piece flexes. The twisted sticks are maintained in position and store potential energy. The free stick snaps back to its usual shape when the first stick is released, converting elastic energy to kinetic energy.

6. Acceleration and Gravity
Using cardboard tubes, students study the link between drop height and object speed in this assignment. Gravity increases an object's speed by 9.8 meters per second (m/s) when it is in free fall. Students test the effects of gravity by timing how far a marble slides down a cardboard tube in one second, two seconds, etc.

Kinetic Energy and Motion Energy
12. Car Safety During a Crash
Students explore techniques to prevent a toy automobile from crashing while studying Newton's law of conservation of energy. In order to design and construct an effective bumper, students must consider the toy car's speed and direction of motion energy just before impact.

13. Creating a device for dropping eggs
This motion energy activity aims to have students create a mechanism to cushion the impact of an egg being dropped from various heights. Although the egg drop experiment may teach potential & kinetic types of energy, and the law of conservation of energy, this lesson focuses on preventing the egg from shattering.

16. Do Different Colors Absorb Heat Better?
In this classic physics experiment, students investigate if the color of a substance impacts its thermal conductivity. White, yellow, red, and black paper boxes are used, and the order in which the ice cubes melt in the sun is predicted. In this way, they can determine the sequence of events that caused the ice cubes to melt.

17. Homemade Thermometer
Students create basic liquid thermometers in this classic physics experiment to examine how a thermometer is made using the thermal expansion of liquids.

18. Heat-curling metal
Within the context of this activity, students investigate the relationship between temperature and the expansion of various metals. Students will see that strips produced from two materials behave differently when set over a lit candle.

19. Hot air in a balloon
This experiment is the best way to show how thermal energy affects air. A tiny glass bottle, a balloon, a big plastic beaker, and access to hot water are required for this. Pulling the balloon over the bottle's rim should be your first step. After inserting the bottle into the beaker, fill it with hot water so that it surrounds the bottle. The balloon begins to expand as the water gets hotter.

20. Heat conduction experiment
Which substances are most effective in transferring thermal energy? In this experiment, you will compare how different materials can carry heat. You'll need a cup, butter, some sequins, a metal spoon, a wooden spoon, a plastic spoon, these materials, and access to boiling water to complete this experiment.

Basketballs have potential energy when they are first dribbled, which is transformed into kinetic energy once the ball hits the ground. When the ball collides with anything, part of the kinetic energy is lost; as a result, when the ball bounces back up, it is unable to achieve the height it had reached before.
