Ocean Unit

PreK scientists completed their study of the pond and are currently in an ocean unit. This lab focused on the difference between salt water and fresh water, as well as understandings about why some things float, but others sink.

We mixed salt into one of two cups filled with water. The salt dissolved and formed a solution. When we dropped the bead into the salt water, it floated but the beads sank in the cup of fresh water. Look at what happened when we dropped food coloring in the cups. Why does the coloring float on top of the salt water? Then we dropped raw eggs into salt and fresh water.





The children shared their ideas about why some things float and others sink. Most believed that objects that are big or heavy sink. Also, things with holes in them sink. They made a hypothesis before they each dropped an item into the tank. When our hypothesis didn’t match the results, we learned something new and that made us rethink our original ideas. (Notice that the larger things are floating.)




Then my PreK students used the microscopes to observe salt crystals. I wish you could have seen their expressions when they first saw the salt crystals.

High School Chem Lab

Mrs. Price’s third grade class was invited for a chemistry lesson hosted by Mrs. McFadin’s AP chemistry class. Her students (some of who were my former students) prepared several chemistry demonstrations and then taught my students how to make ice cream in a bag. Click here to learn more about making ice cream. It is such a blessing to work in a PK-12th grade school!

Zoo Field Trip

I accompanied the Pre-First and kindergarten classes to the zoo. It was a cool day, and the animals were active and so much fun to observe. These scientists just completed their study of animals around the world, so they especially enjoyed visiting the rainforest, desert, and African savanna exhibits.

The bus ride is always exciting for our students because they don’t ride on one often!

It’s a Mystery!

This mama duck and her ten ducklings were spotted on the pond behind school this morning. Our PreK class took this video, When I went out to see them, they were nowhere to be found. I think she has them tucked away safely somewhere in the bushes. Click here to watch a video.

Turtle Visitor

Last year, we witnessed three of our pond turtles dig holes and lay their eggs. We have been hoping to watch this miracle again this spring. Pre-First scientists saw this turtle walking up the sidewalk early Monday morning when it was raining. Could she be on her way to lay eggs?
