when i was in 10 grade i did magnetic plates that floated over each other like in the jimmy neutron show :P i won the best out of the whole high school-i inserted magnets into a paper plates and put them so the bottom one magnets supported the one above it so it didnt fly away
Get some stew meat pieces and put them in multiple (sealed) containers. Have one in the fridge (your control), one in the window, and one in a warm dark place. Measure the decay and bacteria/mold growth over ten days.
When I was in 7th grade my school had a science fair for 7th through 12th grade. I did Planes and how they Operate. My dad helped me make a airplane out of balsam wood and we used a lego man and windshield. I wrote a report and did a poster. Needless to say I won best in show! out of 6 grades I won the best and got a trophy plaque and my picture in the newspaper. That was an awesome feeling. Especially when I forgot my report at home that day and had to run home and get it and bring it back after school just in the knick of time and still won!
When I was in 8th grade, my science fair project was "How different genres of music affect your heart rate." It was a really fun project that involved testing people's heart rates when they were exposed to different genres of music. I ended up winning first place in that category county wide :)
a really cool project is a volcano you get a water bottle and put 3-4 tabel spoons of baking soda in it then add a little bit of vinegar and '''''''' BAMMMMM''''''''''''' you have a science project...........
