Vital Signs – Sheep Heart Dissection
What organ comes to mind when you hear the phrase “vital signs”? A most likely candidate is the heart! There are only a few differences between sheep hearts and human hearts (size and relative location of major vessels) so studying the sheep heart helps our budding cardiologists learn more about the human heart! Campers explored heart anatomy by dissecting a sheep heart and used the heart to identify the circulation of blood throughout the body/to and from the heart.
Ask your camper: Which chamber of the heart receives deoxygenated blood from the body? (right atrium)
Oceanography – Squid Dissection
Today the young biologists dissected another creature from the depths of the sea – a squid! Squid are unique molluscs for a variety of reasons. They have an internal shell called a pen that evolved to support their streamlined body plan, allowing faster swimming speeds. Squid are fantastic simmers that move via jet propulsion; they take in water into their mantle and then expel it forcefully through their siphone. Some squid can reach 20 mph! Interestingly, squid have three hearts, allowing them to pump blood and deliver oxygen as quickly as humans do.
Ask your camper: Squid are invertebrates – what does that mean?
Innovation Through the Ages – Day 2
Today in Innovation Through the Ages, students explored the innovation of aqueducts and how they helped transform the Roman Empire. Then, students were challenged to engineer and construct their own aqueduct that had to function and deliver water from point “a” (the bottle) to the inhabitants of “Aqueductis” at point “c.”
In art and design, students explored the principle of proportion as it relates to da Vinci’s Vitruvian Man. They then measured distances on their own body to see how their proportions measured up. They also examined the Fibonacci sequence and explored where this code is embedded in nature, from the bracts of a pinecone to the scales of a pineapple.
Ask your students the purpose of the arcade element in an aqueduct!
Space & Weather – Compass Creations
Our young Aerospace Engineers continued their explorations of magnetism and magnetic fields in order to create an “out of this world” navigational compass. Magnetic compasses work well here on Earth since there is a natural magnetic field but do other planets have magnetic fields too? How do different magnets respond to different magnetic fields? Campers discovered how magnetism relates to navigational compasses in order to design and build one that could work on another planet!
Ask your camper: Which planet in the solar system has the strongest magnetic field? (Jupiter)

Makey Lab – Toy Creations
Inventing takes time, and our toy creators are on day two of making the final plans for their toy before building begins tomorrow. Today the toy inventors found out the materials they will have to work with, and they redesigned their toys accordingly. Engineers and inventors have materials restrictions, so it is important to learn to work having those restraints. What will the final toys look like? Stay tuned!
Ask your camper: After finding out what materials were available, how did your toy design change?
