Not being around froggies much, I had to refresh my memory:

Another test could be to use different water and see if a different environment makes a difference. (Note: If starting with tap water, it must stand for 3 days min before putting the little squirmies in)

Where are you getting the tadpoles - aren't they more of a spring crop?

This is fun - a group project.

Okay madquilter...were you listening in on her teacher conversation today?!!:)She just came in telling me the teacher had a great idea to go around to different towns and collect water to see if there is an environmental difference in the water vs growth...great...and, how do we do that when we have no idea what is in their water to begin with?!!:)Yes, that God for google....I will be red eyed over this..and, yes, I so agree it is parent vs parent...I dont get caught up in that drama but, a good grade would be nice since this is HALF her grade in this class! Wonder what they aer doing for the other half of the grade? Eating bon-bons I think!LOL Keep 'm com'n quilters!! You already are such a huge help!! Espec in the fact I don't feel alone in this!LOL Skeat

And, we are ordering them tomorrow...once I dig out our old fish tanks out of the barn....well, then there is the maybe wait till we have the water ready...duh, that might be a good idea!LOL

Been there , done all that with 7 so, I know how you feel, Good luck , and try to have fun with ti!!!

In my biology class, we were put into small groups, and each group was given a few tadpoles. We then had to give our tadpoles a certain amount of some sort of hormone every day, put into their water (each group was assigned a certain level of hormone to give their frogs). I was in one of the groups that had hardly any hormone, so our frogs grew at a fairly normal pace, but the people who gave their frogs a lot of hormone -- it was amazing. Their tadpoles grew into frogs in a very short time period - but some of them died, or had abnormalities.

That might be a bit too heavy for a younger kid, though, especially if the frogs die. It was an interesting experiment, though, and not difficult -- we just had to keep them fed, and keep track of how much hormone we were giving them.

Just don't use testosterone or all those little froggies will be beating up on each other. Not a pretty picture - your child will be scarred for life. lol

Skeat---get two or more frogs---feed them different diets and analzye the results by measuring the froggy growth---weight, size, etc.

Maybe feed one Fruit Loops and see what that does for it...lol
(actually, I don't think the little critters would "eat" fruit loops....I wouldn't)

Which brings us to the the question--what do the frogs eat?--bugs, I guess

Let your water sit for 24 hours uncovered to get the chlorine out. Aquatic animals are not happy in chlorinated water (I know from experience!). One question to investigate could be to vary the temp of the water, one could be speed of development vs putting the aquarium in light or dark, one could be speed of development vs brand of food. Good luck!

I hate science fairs too. The kids that need a little more time learning or who have no help at home never seem to have a chance.

BTW -- 50% of her grade on one assignment? What's up with that?

I will probably be soundly booed for saying this, but it is your kid's project and not yours. If you hate science fair projects, then make her do it herself.

Have to say we were never required to do science fair projects when I was a kid. There was a science fair every year, but it was more of an extracurricular thing that only the science geeks did.

What would you weight the tadpole/frogs on?

How would one weigh them with ordinary household scales?
