Thermal Energy

This project is interesting.But,do u have a list of project ideas for middle school students like 6th grade

this is great project good job

this project made me win the science fair !!!!!!!

i dont understand this you should explain this more better.

this project is difficult i dont understand this you need to explain this project more better.but its a good project.

nevermind i understand i just might win the science fair

i  like this  project

I think this is going to be good project??????

this is one of the best science projects

how can you design a device to covert the expansion and contraction and make it usable work,like lifting a rock

sounds like a good project if it were only in the 6th grade level!!!!!   there is no challenge in that section!!!

Thermal Energy
  
Source: The Need Project
 
 
 
Grade Levels:
7-9
 
Question:
Can thermal energy be made to do useful work?
 
Possible Hypotheses:
Thermal energy is/not useful energy that can be used for work.
 
Materials:
Plastic 1-liter bottle
Large balloon
Bowl of hot (not boiling) water
Bowl of ice water
Small rock
 
Procedure:
 
Cool the balloon and the bottle in the freezer for 5 minutes.
Fill the bowl with hot, not boiling, water.
Put the balloon over the mouth of the bottle making sure that the air has been squeezed from the balloon. Place the bottle into the hot water.
The air inside the bottle should expand and inflate the balloon. After it isinflated, put the bottle in the bowl of ice water and observe it deflate.
Design a device to convert this expansion and contraction into usable work, such as lifting a rock. Design a device that circulates hot, then cold, water so that the balloon deflates and inflates without moving the bottle.
Analysis and Conclusion:
Were you able to make a device that performed useful work? Can you think of devices that convert thermal energy into motion?
Can you think of a way to convert thermal energy into electrical energy? Research internal combustion engines and turbine generators
 

this is a great project

this looks like an interesting project! i hope i win the science fair with this! i undertsand it completely. thank you so much. i am only in 6th grade but i'll use it anyways because im a gifted student :D

i dont really care about this science fair thing but ima do this, looks simple. my mother (ugh!) said to pick a science fair and this is the 1st thing i clicked so im doing this.
 
watever
 
~titi XD

i think this can be kinda confusing but once u try it, it can be fun!

This project is great and everything went perfectly. Thank you, You got my child a 100 on her science project.

THERMAL ENERGY IS COOL! i'm doing a science prject on it$

hi loser

thanks for the help

how  is  every  body  doing

i won the faif with this whole thang

WELL MARY ANN A. YOU NEED TO TOP BEINNG SO NERDY IN PUBLIC BECAUSE I KNOW THAT YO MAMA WILL BE EMBRASS IF SHE SAW YO NAME ON THIS WEBSITE SO GET IT STRAIGHT LIL GURL BECAUSE I ANIT THE ONE TO BE PLAYING WITH NOW LETS KEEP THIS WEBSITE GATTO STYLE OK, OK IF U NEED TO SPEAK TO ME THAN COMMENT BACK PEACE

CUTIE SHUT UP DNT NOBODY EVEN NO THATS ON THIS WEBSITE COMMENT BACK

why does everyone have 2 hate on other people? This is commenting on the science experiment!duh! oh and MISSY MISSY u need 2 stop being getto and learn 2 act right!

MISS.MISSY make sure u comment back ok, ok peace!

ugh! i dont get the last part o.o.....
