Here are some fun places to explore soil on the web:
*Get the Dirt on Soil. This site has some interactive soil games and a great field guide to soil.
*ISM Geology. This site has a ton of great lessons on geology for all grades. Activities are well thought out and they suggest well-written books as part of their lessons. This lesson is for kindergarten.
*Sorting Rocks. While this is totally about rocks and sort them by size, the process they employ is a good template. There are a number of more advanced lessons on earth science available.
What is in the dirt? Put dirt in a kitchen strainer and pour water thru it. What happens? What stays and what goes thru? Now put a coffee filter in the strainer and do the same thing. What is left behind now?
Erosion: Make a mountain of dirt and slowly pour water over it. What happens? Make your mountain again. What would happen if you poured water quickly or in a different place?
Growing: Do a dirt scavenger hunt in your yard. Gather up some pots and put different kinds of dirt in to each pot. Then put in a seed or plant and see which soil is best for growing plants.
Eat Dirt: Make chocolate pudding and sprinkle the top with crushed chocolate cookies or chocolate graham crackers. Add some gummy worms and you have dirt for lunch!

Even though chickens are birds with lovely feathers, they cannot fly very far or very well.

Keeping tadpoles is easy. You need a container to keep them in. I like to see them so a clear-sided container is a must for me. Make sure it is clean and well rinsed. Keep the container in an area away from direct sun so it doesn't get too hot. I like glass because it is durable, but I have used plastic bug houses like this for short visits. They are quite inexpensive and have nice handles for transport.
Just about any pond in southern New England, where I am, has frog eggs in early April and tadpoles in May and June. Check along the edges along branches or plants growing out of the water. Use a small bucket or a pan taped to a pole to reach farther into the water.
Gently scoop out some pond muck and check for tadpoles. They generally move around quite a bit after you’ve scooped the water. Be sure to take algae and plant material from the same pond to feed the tadpoles.
No matter what you collect, put them back in their home when they have legs and still have a tail. They need to re-acclimate to their home before leaving the pond.
