Have a kidWhat is a good teenage science fair project?
Here are some ideas:





1. What effect does soap in water have on plants? Is the effect the same at very low soap concentrations as compared with high concentrations?





2. How much plant food is too much?





3. Are dogs (cats/fish/etc.) colorblind? If so, is the lack of color perception compensated by better light/dark vision?





Try to experiment to answer the questions and there you go! You got your science fair project.
Do you enjoy chemistry, electronics, other sorts of technology? It all depends on what kind of science you want to explore. Afford ability, and time restraints are a major thing to look at for picking a project. Here is a link that can help you find one. http://www.all-science-fair-projects.com鈥?/a>
experiment on impact. you drop an egg from a balcony onto different stuff to see what materials best stop the impact and cushion the egg. I like droppin things off of buildings too its fun.
Growing a plant. Grow two plants one with sunlight and water and then the other with artificial sunlight from a artificial sunlight light bulb and water. then see which one grows the fastest.
