Pollen

I’m always amazed at the pollen in Atlanta each spring! After a rainstorm, just look at the pollen that washed into the retention pond! It was interesting to watch the patterns Percy, our silver appleyard duck, created as he swam through it.

Updated Tadpole Post

As you arrive to school in the morning, you can hear the frogs peeping now. Maria brought me some tadpole eggs. We know they are frog tadpoles because they are in a cluster.

Then Patrick found toad eggs on a nature walk. Toad’s eggs are arranged in a chain.

Color Changing Milk Investigation

Kindergarten scientists are learning about the Scientific Method.

I dropped red, yellow, and blue food coloring into pie plates filled with whole milk, and the colors didn’t move when my scientists placed a Q-tip in the center of the colors. Then, they dipped another Q-tip into dishwashing soap, placed it between the colors in the pan, and watched the colors explode! Why did that happen? How did we make green, purple, and orange?

When we cleaned up, we discovered that primary colors mixed together make brown.

Sedimentary Rocks and Fossils

Sedimentary rocks are created from particles of sediment that accumulate in layers over a long period of time and harden into rock. They are often found near water and may contain fossils. I made a sedimentary rock by acting out a story about rain picking up sediments, soil, pebbles, shells, sand, and a small turtle as the water traveled across land. We pretended thousands of years passed and the sediments hardened into a rock. These resemble the conglomerate rocks we have in our rock boxes.


I found the following sedimentary rocks with these fossils when I was a child.

Before the holiday break, third grade scientists pressed shells or dinosaurs into clay at the bottom of a pond (bowl). Then we poured sediments on top of the impression and allowed it to harden. Today, we were paleontologists and excavated our fossils.

Candling

We candled one of our duck eggs. Candling is a method used to study the growth and development of an embryo inside an egg. The method uses a bright light source behind the egg to show details through the shell.  Originally candles were used.  Looks promising!
