Janice VanCleave - Questions and Answers

Page history last edited by claudiascobee 12 years, 12 months ago

I am so honored that your teacher, Mrs. Shanahan has invited me to be part of your class wiki. Your questions will be answered as quickly as possible. I'll leave a note if I must be gone from my computer for a time.

After reading all about each of you, I prepared something that is All About Me .

Looking forward to sharing science ideas,

Janice VanCleave

Science Fair Topic

Question	Answer
Noel: Do these questions have to do with the science fair? Or can they be about any science topic? thanks!	Noel, I am not sure about the rules for your science fair. Generally, the question for a science fair project is either how one thing affects something else or a comparison of two things. Examples: How does temperature affect the speed of a chemical reaction? How does the length of sun-shadows before noon compare with their length after noon?
Plurby: What's the best container to use to hold hot water? Glass, plastic, or paper? Well not very hot but hot enough that it will float on cold water.	Plurby, First, how hot is the water? Hot water from the faucet can usually be held by glass, plastic, or paper. The safest container would be Pyrex glass, such as canning jars. Tell me more about what you are doing with the hot water and I can better give you examples of safe containers.
Fred: Is it better to use more people in my experiment to get better results? In other words, will the results be more reliable?	Fred, Are you testing how people react? If so, then the more data (the more people tested) the more reliable will be your results. For example, "How does age affect a person's reaction time?" The more people tested in different age ranges the more reliable will be your data. In the following example, the number of people performing the measurements can give more credibility to your report. But, the number of measurements that you make before and after noon give credibility to your results if you choose not to involve others. Example: How does the direction of sun-shadows before noon compare to their direction after noon?
Noel: How important is it to include a graph or chart in a science experiment? Why do we need it?	Noel, a chart or graph summarizes information so that the results can be easily viewed. For example, I wanted a general idea about rainfall in Texas--I found a map that was colored--all the brown areas had an average yearly rainfall 5 inches or less--other colors represented different rainfall ranges. I could easily find the wettest and driest areas. The map is a type of chart. The person preparing the map took data from all over the state (rainfall averages) prepared a color legend to represent these averages. As a science fair judge, I like to see the results in chart or graph form.Since a science fair project often determines the relationship between two things, a graph or chart is a good visual representation of the results.
Rapunzel	Dear Janice VanCleave, How can I collect data for a Home made Barometer? Please I need your help!
Shelbi	Mrs. VanCleave, is it true that static electricity occur when negative charge joins with positive charge or is it when positive charge joins with negative charge? Thanks!
