Science Fair
| Account limit of 2000 requests per hour exceeded. |
8th grade science projects are a bit more advanced than previous grades. You will be expected to do your project entirely on your own and enter it in the school's science fair. Eighth grade science fair projects shouldn't be too involved, as you need time to focus on writing the report to go with it. Don't think you need a big drawn out experiment to do well in the science fair, this is untrue. All you need is to pick a topic that you like, be able to explain your project and show how you came to your conclusions. You will also need to have an eye-pleasing presentation.
One idea for an eighth grade science project is to see if you can raise a small fish in an enclosed environment in a glass jar. This project requires some work to set up, but is then basically all observation for about a month. If you don't have that much time, another interesting project is to find out what sort of conditions cause mold to grow on bread the fastest, or to find out if water can travel through plant stems.
For this experiment, all you need is a vase, some water, food coloring and a few white carnations. Simply fill the vase half full with water, add some food coloring and place the carnations in the water. Check them the next day and the flower should show the color of the food coloring in it, thus proving that water can indeed travel through plants stems.

Easy Science Fair Projects Kids Can Do
Doing science fair projects should be fun for the kids. Here is one of our easy science fair projects kids can do that is fun. It needs very little supplies, it also needs very little work, but it will need a little time. It is very easy though and if you have the time the kids will get a trill out of it.
In this experiment kids are going to look at how organic matter decomposes. Your kid will see that soil teems with life such as worms, slugs, millipedes and beetles that feed on the decaying matter. The decomposers are microscopic bacteria, fungi, woodlice, mites and small insects. This decomposing is the process where all organic material is turned into rich fertilizer for the growing plants in the soil.
This project actually consists of two easy science fair projects for the kids to do. The first your kid is going to look at the conditions needed for the decomposing process and in the second your kid is going to look at the decomposers.
Remember to make meticulous notes from your hypothesis to your conclusion and for your display purposes it is a good idea to take photos of each step as you go.
Having a look at the optimal conditions for the decomposing process:
What you need:
* A trowel
* Good soil
* Dead leaves
* Water and a watering can
* Two clean plastic containers, one with a tight lid
* Tags
* Pen
* Note book
* Camera
* Plastic gloves
This is what you have to do:
Wear your gloves for both of these experiments
1. Remember your notes and photos
2. Using your trowel fill the two plastic containers three quarters full with dry soil
3. Place a layer of dead leaves on top of the soil in both containers
4. Mark the container with the lid "A" and the other "B"
5. Now you water the soil and the leaves in your container marked "A" thoroughly and press the lid on
6. Keep the soil and leaves in the container marked "B" dry, do not add any water to it
7. Place both containers in a dry place and wait a few weeks
8. Have a look at both and you will notice that the leaves in the wet soil will have begun to rot while the leaves in the dry soil has dried and shriveled.
In the next experiment that is the second of our easy science fair projects for kids to do we are going to look at the decomposers.
What you will need:
* Once again your plastic gloves
* A plastic funnel
* A large clear jar with a neck into which the funnel will fit
* Some rotting leaves from a compost heap
* Black paper
* Sticky tape
* A desk lamp
* A magnifying glass
* A field guide
* A notebook
* A pen
* A camera
This is what you have to do:
1. The plan is to see the insects on the rotting leaves
2. You are going to separate them by using a lamp, a funnel and a large jar
3. Place the funnel in the jar
4. Wearing your gloves loosely fill the funnel with your rotting leaves
5. To keep out the light, you have to tape the black paper around the sides of the jar so it is dark inside the jar
6. Now you place the lamp in such a position that it shines onto the leaves in the funnel
7. What you want to happen is for the insects on the leaves to move away from the heat and light from the lamp
8. While doing so they will fall down the funnel and into the jar.
9. After an hour, take a way the lamp and remove the black paper from the jar
10. There will be several insects in the jar
11. Identify them by looking at them with the magnifying glass and the field guide
12. When you are finished, return them to where you found them and be careful not to kill them. These creatures are very important in the eco system of the earth!
As you can see, kids will be able to the most of the work in these two easy science fair projects for kids to do. The two combines should give you enough material for a good display.

There are things you need to know about doing a science fair project in the correct way. For all the info have a look at Magriet's Squidoo Lens:

What kind of science fair project is related to bubbles?
Can anyone help pick out a science fair project in which I can experiment that is related to bubbles? Please keep it simple, and list the steps on how to experiment.
How can germs get past the cell membrane?
Get a bubble blower thingie(square works best) and two pencils. Dip the blower into a soapy solution and hold it up, then take the pencil and try to put it through the bubble. It pops. Now, take the other pencil, this time dip it in the soap solution and then put it through. This pencil goes through because this "germ" coated itself with a similar membrane, tricking the cell into letting it in.
Science fair win boosts student's confidence
After winning silver at a national science fair, Lakefield's Sarah Langer said her life changed for the better: She finally had the confidence to attend university and made friends around the globe after travelling to North Africa to present her research.[...]
