Taking care of tadpoles
1. First you'll need a suitable container, like an aquarium or fishbowl. Choose a container that will be easy to keep in the classroom.
2. Tadpoles need fresh, clean water. If you take the water from a local stream, creek or pond, be sure that it’s polluted. If using tap water, let it stand exposed to sunlight for one week. This will allow the chlorine to be removed by evaporation. Even a little chlorine is can be deadly to tadpoles.
3. What do tadpoles eat? Fish flakes or aphids from a pet store.
4. The length of frog development from egg to tadpole to frog usually takes between six to 12 weeks. Development is temperature dependant, so be sure the temperature is regulated in your classroom.
5. At this point, if they aren't big enough to eat crickets but are too large to eat fish flakes, you can give them small insects. A good substitute is bloodworms, which are usually found in pet stores that carry fish. You can try feeding them to the frogs by taking the lid of a jar and turning it upside down. Fill the cap with a bit of warm water and lay a bunch of the worms in and allow the frogs will find them. Or you can put the worms directly into their water.
6. Young frogs will need a lot of ground cover to hide as well as structure to play in.
7. Make sure that you teach your students how to properly handle, care and most importantly, how to respect their new froggy friends!
