Chemapalooza’s Instant Ice Cream

Chemapalooza’s Instant Ice Cream

Most people have eaten ice cream before, but have you ever made it yourself? Today campers not only made their own ice cream, but instantly froze their creations with super cooling liquid nitrogen (with adult assistance of course). A famous ice cream recipe was lost to the world, but our campers experimented with different quantities of ingredients in order to make the most delicious ice cream of all!

Ask your camper: What was created when the liquid nitrogen was poured into the liquid ice cream mixture? (a gas)

Astronaut Suit-Up – Space & Weather Day 2

Astronaut Suit-Up – Space & Weather Day 2

Today our awesome aerospace engineers were tasked with the goal of designing their own pairs of space gloves that have the ability to protect an astronaut from the extreme temperatures of outer space. By using the knowledge they gained from all the materials testing conducted the day before, our campers were able to make wise materials choices to ensure that their space gear is able to provide maximum insulation.

Ask your camper: Explain the design of their space gloves and why they chose the materials combination that they did for their gloves?

Swing to the Stars in Makey Lab

Swing to the Stars in Makey Lab

Shall we swing right to the stars? Today our playground engineers continued their work on building out their playground and were challenged to design a swing that could carry different loads. They learned that a swing is actually a pendulum—a weight hung from a fixed point so that it can swing freely backward and forward.

Ask your camper: Did changing the weight of the pendulum affect the times? How did the times change? (The time should not change –only the length of the pendulum affects the time.)

Sea Glasses in Oceanography Day 2

Sea Glasses in Oceanography Day 2

Some of the most fascinating of sea creatures live in the deep ocean – deeper than rays of light can penetrate. Over generations, these sea creatures have changed colors to help them survive in the deepest parts of the ocean. Today the “under-the-sea interns” examined how light travels beneath the waves and how it affects the living organisms and their survival. The campers created specialty “sea glasses” that allow you to visualise how much light reaches the various depths of the ocean by layering blue cellophane. Using their sea glasses, the campers tested different color fabrics and images of marine life so they could see how visible the sea creatures are at different depths of the ocean.

Ask your student: How does the coloration of the animal help it to survive at different depths of the ocean?
