Question

any suggestions? :)

Answer 1

Do white candles burn faster than colored candles?

Find out what color candles burn the fastest. All you do is time them.

Answer 2

skateboard wheels

the idea is to get different size wheels and different hardness of wheels and put them on a skateboard with the same variable...meaning use the same skateboard....same bearings...and same slope ( or hill/driveway) and roll it down that hill/driveway and time it to see which one gets down the hill quickest...this should be done a number of times and wind condition should be taken into account. another thing to look at is how straight it goes and how smooth is it....by placing an object on it and see how long it stays on the board...if you want more detail email me and ill send you some other variables you need to consider and how to report this....the key to any science experiment is the number of times you do it...bcuz there will be a % error in your report and you should know hot to report this


another good idea is parachutes....what kind of shapes are the best....circular, rectangular, oval square and with or without holes in it....determine which one falls in a straighter path and the timing of it....you might not be able to determine which one is best...bcuz you are not sure you want a fast down time or slow...fast is good if you are maybe in the airforce and need to get down quicker....slow maybe if you want to get a good view...one thing to keep in ming is...the weight of he object attached to the parachute and maybe the wind condition..report what direction the wind is blowing and how fast...you can make up a different way to report how fast the wind is blowing and that would count for big points for a 4th grader...be creative.
