Can anyone help me with a science project.... im not asking for answers to a test!?

Question

Hey there everybody....

In times of need i always come here and i need YOUR help! I have this science project and we have to make a device that changes one form of energy into another form for example a touch changes chemical energy into light.....

We are not allowed to do the torch one i have listed above! Does anyone have any ideas on what i could do?

Thanks in advance

Answer 1

a battery can change chemical energy into electrical energy, which can then be turned into light with a light bulb, or heat with a resistor, or air movement with a fan.

similarly a rubber band can store energy that can be used to move an object.

Answer 2

flashlight changes electrical energy into light. this would work i think

make it a good day

Answer 3

Battery uses electrochemical reactions.

Anything that has friction will change kinetic to heat.

Thermocouple will change heat to electrical.

Photovoltaic will change light to electrical.

Curved track will change kinetic to potential and back again.

So will pendulum.

Plants will turn light into chemical.

A twisted rubber band hooked to a propeller will turn torque into forward motion.

A motor will turn electrical into motion.

An engine will turn chemical into motion.

Answer 4

Here are some examples:

Ptyalin (chemical in our saliva) changes some food into sugar.

Electrical Energy from battery make light.

Solar Energy make light.
