August last week.. We researched what kind of habitat our frogs tadpoles would need and created a list of things we would need to purchase and have ready before the tadpoles arrived. We discoverd that you can feed them lettuce that has been boiled and chopped or purchase food from a pet store. Their water can be collected from the faucet but will need to set out for 7-10 days to remove the chlorine or we can add 6 drops of stress coat to 1 gallon of water to remove chemicals from the water. The children compared our drinking water to pond water and why tadpoles would not survive in our drinking water. We discovered their habitat can not be placed in full sunlight and the effects of the water temprature on how long it takes them to change from tadpoles with no legs to tadpoles with 2 hind legs.

Sept. 1st week We ordered our tadpoles and discussed how to purchase with on-line shopping and compared it to going to the pet store. We discussed how the tadpoles would be transported to our school.

Sept. 3rd week. The tadpoles arrived and we place into the prepared habitat. We predicted how long it would take for them to change. We observe and record what we see on a hundreds chart everyday. We also record in our daily planner the days that we feed them. Oct. 1st week 1 tadpole dies. We shared our possible explanations to how and why it happened. We decided it maybe due to the tank and decided to clean the tank once a week. We now record in our daily planner the days that we clean the tank. We have had the tadpoles for 24 days and still no change.

Friday, October 8th, 2010 Our 2nd tadpoles died. These our the first grade students response

Possible causes 1.not enough sunlight. 2. Maybe the water wasn't the right temperature. 3. Maybe something was wrong with the tadpoles digestive system. 4. Water chemicals were not right for the tadpole. 5. Maybe the noise of tapping on the glass.

Possible solutions 1. Put a lid on the tank. 2. Move the tank to a place that it will recieve some sunlight but not to much. 3. We will try different water that does not have chemical in it. We will buy water from thepet store, or a store in town.

October 13th We Welcome Our 3 New BullFrog Tadpoles



Created our tadpole cover page for our book.The we drew and wrote about what we see so far. We researched for information that would guide us to make an accurate prediction of when we believe the tadpoles will grow their forelegs.

Each day we mark an x on the hundreds chart to show that we observed no change. Each day we check the water and the thermometer to ensure that we keep the water temperature the same. Today we removed 25% of the water and added fresh treated spring water.

We have not observed any changes on the tadpoles bodies. We are looking for the growth of their front legs (forelegs).

We fed the tadpoles and cleaned the tank.

Fed tadpoles Fed Tadpoles and change their habitat. We moved the tadpoles to a larger tank with rocks inclining up the tank to a larger rock and log. We hope moving them to a larger tank will provide them with more room to exercise and use their back legs. The slope of the rocks to the larger rock and logs will provide them a place to climb out of the water. They have not grown any front legs yet. The children compared this new habitat to the enclosed fish tank habitat and shared how they think this habitat is more like the frog habitat in nature. They now hide underneath the green plant we placed in their new habitat.We have observed our tadpoles for 56 days. We have kept the temperature between 68 and 72 degrees. We have kept the airflow clean and changed 25% of the water each time we cleaned the tank. They continue to swim around and eat.

We still havn't observed the tadpoles growing their forelegs. We have discussed why that might be and decided to add a lamp to their habitat. Because it is winter they are not receiving the same amount of light as they would in the summer when they would normally go through this change. We believe this will increase the amount of light they will receive which will imitate a natural environment for them to grow.

Fed tadpoles Fed tadpoles add fresh water Students debated the idea of adding predator pressure to cause the tadpoles to move around the tank more. They came up with various ideas on how to do this. Predator Ideas 1. turtles 2. another frog 3. lizards 4. children scaring them Probing question to children: How would we know how much pressure is healthy for the tadpole and how much pressure could cause them to die? Students responed that we don't know so therefore maybe we should add a fake frog to the tank.
