Dating science fair projects
The projects are categorized by their difficulty. This experiment may help you find out. If you're not sure about which project to pick, why not take our Quiz to see which project you might be interested in. Physical Science Thank you for your input.
So why don't we get to know them and play with them. Physics Optics Predict how high a ball will bounce.
But a science fair project is not about theory, it is about setting up an experiment with a control and experimental variable. Physics Explore the properties of pendulums and what factors influence its motion.
This poorly-named project investigates the reason that balloons expand and contract in different temperatures. In this science project, each coin represents an atom.
Explain why this experiment was useful in replicating a model of radioactive decay. Chemistry Use this experiment to see what the probability is of landing a coin on its edge. Now collect the coin that were tails and put them back in the bag. There are many studies about the reactions of human beings, when attracted to another person. Now spill the coins out on the table in front of you.
Copy the Data Chart provided below so that you can readily record your observations. In this project, you can find out how much a bag can hold, so you can impress people next time you go to the grocery store.
This corresponds to the decay of half the atoms in a radioactive substance and therefore the coins are indeed a good model. Explain what each coin represents.
Sounds like an interesting idea. Hopefully, the result is a clear- cut operational concept of the half- life of radioactive substances.
