science fair project with frogs

[adamsmom]

My son is in 4th grade and wants to do a project on the life span of frogs. From tadpoles to frog. But we can not think of a hypothisis that would tie into this.

He is also very interested in computers .
Please help

Hi adamsmom

There's an existing project in this website's database at:
[url]http://all-science-fair-projects.com/project31_78.html[/url]

Perhaps he could do something similar - i.e. investigate the effect of some factor on the lifespan of a tadpole.

The factor to investigate could be amount of food, type of food, pH of water (as in the reference project), sunlight etc.

Hope that helps some.

Also, take a look at the encyclopedia section for general info on tadpoles/frogs/lifecycle:

those are goo idea scienceiscool keep up with the good work...
anyways here is a hypothisis...

To investigate the ph in the water where the life cycle of frogs live...

or

To investigate how viruses infect the computer...

hope it helps...

good luck

Why don' you do it on your guess on how long they will live in a certain condition?
