Bumblebee, Oothecae, and Lava Lamps

Today during project time we were able to examine a bumble bee that Mr. Mark found outside. We noticed two pollen baskets on the bumblebee. We were also thrilled to discover that our praying mantis oothecae (egg sacks) had arrived. We can’t wait to watch our praying mantises begin to emerge in the coming weeks. Today during science we created our own lava lamps. We discussed the density of two liquids; water and oil. We added seltzer tablets to create a reaction that caused CO2 bubbles to form. These bubbles attached to the colored water bubbles, causing them to rise to the surface as their density changed.  When the CO2 bubbles detached from the colored water, the bubbles sank back down.  This happened repeated to create a lava lamp effect. During writer’s workshop today we learned how to use dictionaries to spell words correctly. We also practiced spelling our oa words.
