On Monday, Biologist Emilie, an expert on Vernal Pools, visited with Room 3. We discussed the wildlife that calls the vernal pool home and had the opportunity to see frog eggs, yellow spotted salamander eggs as well as plants and insects. Emilie was also able to enter the pool to catch a bullfrog that one of the students spotted with their eagle eyes!
We have tadpoles! The children were excited to see what changes might have occurred over the weekend. They carefully observed the tank to find that many of the eggs hatched over the two days we were away. One observer noticed that the tadpoles were all sitting on the bottom of the tank and wondered why? Later in the day, another observer noticed two of the tadpoles had started to swim. Some questions that have been asked today include:
Why are there still eggs with a circle in the center?
Will the tadpoles eat the leftover floating jelly?
Do we need to feed them? What will they eat?
Why are they all just sitting there?
They’ve arrived! Room 3 was thrilled to see Ms. Erickson today as she delivered our frog eggs. We were able to compare the frog eggs to salamander eggs, as Ms. Erickson had also collected a large mass of them. The children looked at them very carefully and began to journal about what they saw and what they wondered.
The students in Room 3 met Emile, a biologist from Grassroots Wildlife Conservation, who shared information about the Vernal Pool habitat. The children held and observed frogs, salamanders and Predaceous Diving Beetle. They talked about what the creatures need in order to live and grow. What a great day!
The children are wondering why the tadpoles tend to spend much of their time together in a group and against the tank wall?
As the tadpoles grow bigger, the children are beginning to notice more specific details about their features. Some students have noticed tadpole eyes while others have seen the open and closing of their mouths. The children have noticed the length of their tails are getting longer which is causing them to swim more quickly. Others have seen where their legs will grow, in just a short time. Students write and draw their observations each day in their Science Journals.
The tadpoles, they’re just like us! The children began to notice a significant amount of movement in the tank today. Most enjoyable, was watching the tadpoles “play” in the bubbles! The children observed the tadpoles swim into the stream of air bubbles at the bottom of the tank and then get pushed up to the top! It looked like fun!
The children noticed some tadpoles were still spending most of their time on the bottom of the tank while others were exploring their surroundings!
Today the children were asked to think of some variables that would effect the growth of our tadpoles in positive or negative ways. The children considered:
* Light. Would they grow at the same rate in a dark room?
* Water. Could they continue to grow without water (we quickly new the answer to this one!)? What if we had less water in the tank? What if the tank water was dirty?
* Food. What different foods could we give the tadpoles that might make them stronger? What foods would they not like to eat? Do they eat live insects yet?
* Number of tadpoles. Would less tadpoles grow more quickly? Would they eat more food and not have to share?
Our tadpole eggs arrived in the classroom today. They were gently placed into the tank, prepped with an air filter and a rock. The children described and wondered:
“There could be more than 1,000 eggs in there!”
“I wonder if the clear goop is protecting the babies?”
“I wonder how they will get out? Do they eat the gel? It doesn’t crack like a regular egg, does it?”
“The babies are all curled up.”
Today we explored a hidden gem right on our own Woodland School campus…a vernal pool! Guided by Emilie, a biologist from Wildlife Conservation, we carefully observed the vegetation, animals and insects located in this area.
