Fish Nests
5/5/2018
This week we continued to talk about nests. We examined real nests and a collection of real eggs. Our collection's largest egg is an ostrich egg and our smallest is a quail egg. We also have a display of the salmon life cycle borrowed from a hatchery. We spent time discussing what kinds of nests different eggs need and how the parent animals make them. We made clay eggs to fit into our clay nests. Some students many one large egg while others made many tiny eggs.
After our herring dissection last week we have been interested in fish. We talked about, and looked at underwater pictures, of how some fish lay eggs in special nests called redds on the bottom of rivers. We then used the rest of our herring from Bristol Bay to make fish prints. Our explorers were excited to get to paint real fish! After they made their print they stamped river rocks with sponges and added fish eggs with their fingertips. It is exciting to see our students integrating their curiosity, learning, and creativity in this study. We also did a scientific experiment about egg strength. For the morning question we generated a hypothesis for the question "Are you stronger than an egg?" We had 13 yes guesses and 2 no guesses. To test our hypothesis each student took turns seeing how many textbooks they could hold. The data ranged from 4-11 books. We then stacked textbooks on top of 4 eggs. The eggs held up 16 books before they smashed! In the conclusion of this experiment the students decided that eggs needed to be strong to protect the baby growing inside. Comments are closed.
