A Brine Shrimp is a Sea Monkey?

In an effort to continue our study on brine shrimp, the students were presented with a kit that allows them to grow brine shrimp.  The kit included brine shrimp eggs, a water purifier, a magnifying glass, and food.  They quickly discussed a plan for how to care for the brine shrimp as they gathered supplies they would need to create a thriving environment for the brine shrimp.  This type of direct instructions allows children to learn more about the brine shrimp by observing them and caring for them.  They have the potential to discover the dietary habits of theses organisms as well as how the move.They began with a discussion about room temperature water.  They made predictions about what temperature the water should be.  Some said that maybe room temperature water would be 30 degrees while other suggested 90 degrees.  The teacher reminded them about their weather study and how the looked at the thermometer to determine the temperature.  The children recalled how when it was 90 degrees or higher, it was very hot.  Coach Chip asked the children if they thought their brine shrimp could live in water that was always hot.

The students began to talk more about the temperature when Jennifer said maybe its 70.

Before they could start, they broke up into teams.  Each team would be responsible for some aspect of care for the brine shrimp.  The first team had to ensure that the water the class would be using was room temperature.  They carefully filled the container to the line with bottled water that had be sitting on a shelf in the room to guarantee that the water would not be too hot or too cold.  They measured the temperature of the water to make sure that the shrimp would live in the right temperature of water.

Then they very carefully included a water conditioner to soften the water.

They allow the water to sit over the weekend before they began to add the eggs.   As they added the eggs, they made predictions as to how many shrimp would appear. They looked at the directions to find out how to care for them now that the eggs were added.  The teachers and the students discussed how they had just completed step two as the students looked ahead to see what to do.  They checked the feeding schedule and tried to determine what the brine shrimp would look like.

 They were not sure if their sea monkeys would look like the brine shrimp that had seen in the microscope, but they knew they needed to  be fed.

They fed the brine shrimp according to the schedule.

After each feeding, they would place the shrimp in a shaded area in the winter.  They wanted the water to be warm but not too hot. And they began to wait to see if they could get them to grow until it was time.They took the brine shrimp into the hallway and turned off the lights.  As the lit the miniature tank, they were able to project the microscopic organisms on the wall.  The children squealed with success as they witness the small squiggles move on the wall.  The best way to teach children about living and non-living organism is to allow them to experience them first hand.  They now have an understanding that organisms need shelter, food, and that they can reproduce all through this fun and memorable experience.
