You can do the effects of different shades of light on photosynthesis. For example have a couple plants set up, and expose some to full light (artificail) and some to different shades of light (can cover light with these shaders of different percentage) and maybe another in total darkness. Then compare. They all should grow, but they will look all totally different.
How about a topic that might educate other students... Explaining how sunburns and tanning booths can cause Melanoma. You get to learn and explain the biology of our skin. How the body protects against UV rays and how some cells become cancer cells.
What are some science fair projects that are easy and quick to do?
my favorite one is that u can predict how many apple seeds will be in a certain type of apple. take 3 types of green and 3 types of red then average the totals together and guess how many seeds the 4th type of apple will have like green u could do Gayla Golden delicious and granny smith. and for red you could do red delicious Pink lady and the grocery store will have more.
also you could explain y salt dissolves in water y oil does not mix with water,
also an easy one explain diffusion take food coloring and 3 cups of water 1st place food coloring in water that is room temp. then boil water and see if it goes any faster. next chill water and see how long it takes for the color to disputes. the last one might be the easiest one to do just take some pics while it is disputing and u will b fine!
What our good science fair projects for High School Students?
These science fair sites can help with ideas, though don't count on "easy":
What are some good science fair projects for eight graders?
I can direct you to a site that has lots of ideas and they give grade levels so that you can look through and pick something that is appropriate. There are probably over 500 ideas. For example: The first topic is, Aerodynamics & Hydrodynamics Project Ideas and it lists 27 science fair projects for grade 6-8. There are also ideas for both the higher and lower grade levels.
When you click on the first topic 'Aerodynamics & Hydrodynamics ' at the top of the page there is a scale using little squares that shows grade levels and icons for 'show easier ideas' or 'show harder ideas'. There's lots for you to browse through.
What are some good 7th grade science fair projects that have to do with earth science or physical science?
This may be a little involved for a person of your age, ask your science teacher if a project in archeology would be ok. If he/she approves, then how about doing a mock up of what the city walls of Troy, Mycenae, or Tyrnes. A buddy and myself did a couple of these in High School and got A's. It takes awhile to build it but man does it look great after you get the walls in place. Made out of clay, plaster of paris, and bathroom tile (1"x1" brown). Get the Book "March of Archeology in your school library. I believe it is the one that contains a drawing of the different levels of Troy and its walls, as the same with the other two. Warning. Once you get into this Troy thing you may be hooked for life. The more you find out about those old cities and legends the more there is to find out. In other words it may become a lifetime project if you let it. Best Wishes for your project.
What Are Some Good Science Fair Projects That Aren't Too Common?
I did a really neat project in my science class. I built a hydro-electric generator that powered a lightbulb.
It may seem hard, but its actually quite easy and there are many blueprints online. As far as materials, you're looking at some strong magnets, some plastic spoons, some copper wire, one of those mini lightbulbs I'm sure your science teacher has, and a tap.
This project not only amazes because you are actually generating electricity yourself, and is extremely easy. Good luck!
