Brine Shrimp Eggs (Sea Monkeys)



As part of our new science unit, living things, we have been doing Science Court. This computer program is a court case about characteristics of living things. The students are learning how to identify living things, dead things, and non-living things. Part of the court case is a test to see if eggs, specifically the brine shrimp, are alive, dead, or non-living. So we decided to check it out. We added the brine shrimp yesterday to our purified water. Now, we are making observations and inferences about our eggs. Most of the students voted that they have the potential for life. We will continue to observe and see if our inferences are correct.

We are also working hard on creating models of the Earth. We are using pumpkins as our beginning sphere. Today we made many observations about our pumpkins. We decided that the lines that run north and south on our pumpkins really do resemble lines of longitude. We began our project by painting our pumpkins blue. We will continue by coloring our continents and then marking our important lines and points next week. I will post pictures as we progress. We are very excited.
