HEAT AND EVAPORATION PROBLEM: Does more heat make water evaporate faster. To test this I observed how the heat affected the evporation rate when water is placed under DIFFERENT WATTS LIGHT BULBS.i decided to do this expierment because I noticed how the water in my pond evaporates because of the sun every week we have to put water in the pond with our water hose. HYPOTHESIS: MY HOPTHESIS WAS THAT THE 75 WATT BULB would evaporate the water faster.all substances have molecules those molecules

Do you know any Hobbits? No not the ones from the movie. There has been a discovery that proves the Hobbits truly did exist‚ teeth were uncovered in Southeast Asia along with a Skelton. These two objects were verified to be only 18‚000 years old‚ which was a surprise for the human ancestors living in Africa 1 million years ago had about the same teeth characteristics as the one found. The discovery of Hobbits most certainly affects our understanding of human evolution. After realizing that these

This science fair project is designed to show how dogs heart rates increase with exercise and activities. Loads of people were wondering if older dogs’‚ or younger dogs’ heart rates would go up more when exercised. Well‚ we can show you! The hypothesis is that hopefully the younger dogs heart rate won’t go up as much as the older dogs’ heart rate. This science fair project is relevant due to people needing to recognize how to exercise their dogs according to what they can and can’t do age wise

I am Jessica Bogde and the title of my project is‚ “The Catapult.” I chose to do this project because in the fourth grade‚ one of my peers inspired me to build a catapult because she built it as her Science Fair Project. I also wanted to do this project because I love building things and this project just added to my experience in building things. I chose to work alone on this project because I work faster when I am independent because other people mess around sometimes. I also chose to do this
