need a 7th grade science energy project!!!!?

Question

the project has to be sumthing besides the average battery and light bulb thing

i need a project that is fun and entertaining in appearence
the project also has to be about something similar to energy and it has to be a project in which materials wont be too costly

plz and thank you

p.s. the project has to be guarenteed to work and able to be demonstrated in a classroom

Answer 1

Here's one that's very fun using solar energy. http://home.earthlink.net/~apptechy/NewSolar/NewSolarKit.htm

You can buy supplies from your local hardware store or http://www.scienceprojectstore.com/

Answer 2

ahh seventh grade, i remember it like last year. that's because it was! Anyway back to your question, here is some suggestion: when i was in 7th grade i did a project to see if the weather affects a bean growth? it did not win any awards but..... but now that i am in 8th grade, im building a solar powered toy car. i don't know what that has to do with science, but my science teacher said it was cool to do it.

Answer 3

Can you bring a schmorgasborg of examples of things that have energy that people don't even think of?

Everything with mass has energy, but I'm talking about things like a rubber band wrapped around a ball has energy -- it's squeezing the ball constantly. Or a slinky? Transfer of motion (energy) between two billiard balls? I bet the teacher would like the fact that you did something outside of the box like that, and it would help explain to the class something they may not have all realized.

Answer 4

How about something to do with

electrical energy
and
human calorie consumption and power output.

You could get one of those bicycle light generators,
measure the power output when you cycle and light
a light, calculate the power output in calories, compare
this to those exercise chart numbers for losing weight
by cycling. Explain the differences.

Or
Tabulate your meter reading on your electrical
consumption for your house/apartment/dwelling.
Measure and write down several times a day.
Look at variations due to cooking, showering,
cleaning, how many people are home.....

or

make a calorimeter for testing the energy content
of various materials by burning them and measuring
the temp. rise in a known mass of water. test
several foods, wood, oil.....etc.

Answer 5

nuclear power. A nuclear power plant looks like a volcano which can be made with clay or paper mache. Paint it white with a radiation symbol somewhere. Finally, put the battery in the volcano shaped power plant. It's the same battery light bulb thing except that it is nuclear power and it looks cooler.

Answer 6

I can't tell you how to do the project, that would defeat the purpose of learning, but a demonstration on electricity can easily be researched, built and inexpensive if the hardwarestore is nearby.

Answer 8

you could do plant growth in coffee grounds, or plant growth with different amounts of light, etc.

Answer 9

make a poster with a picture of a lightbulb and when you color on it it changes colors....
hahah. im so funny
