All About Frogs

With my youngest scientists, I always try to begin lab with a song or fingerplay. We sang Five Little Freckled Frogs which connects math and science.

PreK biologists observed our lab frog, Yoda, and noticed the changes in our tadpoles.

We put the stages of metamorphosis in order We realized that we should be in a circle, not a line, because this is a life cycle.

We used forceps, a science tool, to feed our frogs. We pretended the rice were small bugs which was a great activity to develop fine motor skills!

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Frogs are amphibians and must keep their skin moist. They don’t just wear it; they drink and breathe through it. Frogs don’t usually swallow water like we do. Instead, they absorb most of the moisture they need through their skin, so I introduced the concept of absorbency. We moved to the lab tables and used pipettes to test whether the materials were absorbent or nonabsorbent. Notice items around your house that absorb water, such as towels or those that do not, like rainboots or umbrellas.
