Oceanography – Blubber Gloves
Blubber is an adaptation that marine mammals have to survive the frigid ocean temperatures. The young marine scientists used conducted an experiment today to create the most effective blubber possible! Upon first testing the temperature of the water, students found they could hardly hold their fingers in the ice water without protection more than their two layered rubber gloves. The marine scientists then were able to use materials like vegetable shortening, petroleum jelly, and cotton balls inside their “blubber gloves” to model actual blubber.
Ask your student: What was the dependent variable in the experiment today? (amount of time your hand was submerged in the water) What was the independent variable? (the material used to create the “blubber”)
Makey Lab – Merry-go-Rounds
The playground engineers of the local school have asked for our help! They lost the plans to all of the new playground equipment and it’s the job of our young engineers to design and build a new merry-go-round. Along the way the campers learned about centripetal force, which is the force needed to make something move in a circle. After building their merry prototypes, the campers tested their designs with differently massed objects.
Ask your camper: What is centripetal force?
Space & Weather – Galactic Glow & Goo
One primary reason why space has captivated the human imagination for so many centuries is arguably because of the beautiful lights and dazzling twinkle that can be seen in the night skies and today, our scientists were able to capture some of that “galactic glow” in the classroom. Campers were able to learn about some of the different ways light gets produced and even created some glow-in-the-dark slime to keep as a momento as well.
Ask your camper: What is chemiluminescence?
