2 Easy Science Fair Projects [sciencetechnology-center.blogspot.com]
Gav and Dan accidentally discover how to punch the sky in the face with a can of butane. If you happen to find the charred remains of the can on your rooftop or you spot it orbiting the earth with a telescope, please let Dan know because he wants it back.

Here are a pair of easy science fair projects you can do around the home; one of them is good for biology, the other one teaches physics rather nicely.
These are projects that can be done with a minimal expenditure, and one where the bulk of the work is done by the student, rather than by their parents, and where it isn't just handed to the student in a pre-fabricated kit.
This is real science, and it will teach your students some decently important things about how the world works; most importantly, it'll teach them to ask questions, sort out the answers on their own, and show their steps and their data.
Easy Project Number One: Phototropism in Plants.
For this science experiment, you're going to need a couple of bean sprout plants - these can be gotten pretty easily at any greenhouse or gardening store, and they're pretty easy to get in the spring time. You'll want three seedlings, minimum.
Next, you're going to take some old milk car tons, or cereal boxes, and cut some holes in them; use the cardboard you cut from them to make some internal "shelves". Put the holes and shelves at different heights, and all on the same side of the carton.
Put the plants in the carton, one in front of a low hole, one in front of a medium height hole, and one in front of a tall hole. Water the plants regularly and normally, but ever time you let them be, put the cereal box cover over them.
What's different about the plants at each hole? All three of them grew, but each of them grew differently, as if it's growing towards the light. (Bean sprouts grow pretty quickly, which is why this is a good easy science fair project.)
If you make the internal slats more elaborate, you can convince plants to grow in all kinds of directions this way. Think about what this means for farming and for hydroponics, and write a short report.
The Even Easier Second Project: Eureka!
We're going to do Archimedes experiment with pitchers of water and measuring cups. Fill the pitcher all the way up to the brim, and put a measuring cup underneath its spout.
Now, drop common household items of about the same size and mass into the pitcher, and measure how much water spills out. Good candidates for this are a ping pong ball and a golf ball. The difference in water displaced is their difference in density.
This "water displacement effect" is how the Navy measures the weight of ships - after all, an air craft carrier is 600 yards long! It's kind of hard to pick it up and put it on a scale! (A nuclear aircraft carrier has a displacement tonnage of 92,000 metric tons!)
