Vital Signs – Breaks/Sprains/Strains
Common summertime injuries that can happen to kids while they’re playing outside on play sets, running up hills, falling off bikes… Today our doctors dove into the study of orthopedics and learned how to identify and treat various types of fractures as well as muscular strains and sprains. Students got to practice wrapping each other’s ankles and/or wrists in a comfortable and supportive manner such that it effectively immobilized the limb to allow it the chance to recover. They then had to learn how to identify and model different types of fractures that can occur in the bone, including transverse, butterfly and spiral breaks.
Ask your camper: What is the difference between a sprain and a strain? (A sprain is when a ligament has been badly damaged or torn and a strain is when a tendon or muscle has been damaged or torn.)
Oceanography – Microorganisms
NOAA needs our team of oceanographers to investigate how temperature affects plankton physiology – ocean temps are on the rise, after all! Plankton play an important role in all water ecosystems, especially being a food source for many larger animals. If rising temperatures affect plankton adversely, we may need to anticipate a lot of trickle-down effects on the organisms that depend on them as a food source. Daphnia, commonly called water fleas, were studied today when our aspiring oceanographers turned their camera phones into microscopes in order to observe plankton physiology (such as heart rate, or abdominal pulses of the Daphnia). Yesterday they collected baseline physiology data (room temperature) and today they repeated their experiments using ice water and/or warmed water.
Ask your camper: How did the ice affect the physiology of Daphnia? (colder temperatures resulted in decreased heart rates). What about the warmer temps? (warmer temps resulted in increased heart rates and sometimes death)
Space & Weather – Convection Currents
Up, up, and away!! Yesterday, our meteorologists were able to study the movement of convection currents in water – (and how those can end up resulting in hurricanes…!) – and today we shifted our attention to seeing how convection currents behave in the atmosphere by designing colorful tissue paper hot air balloons! Students worked in groups to figure out the optimal hot air balloon shape, size & design and then they harnessed the power of air convection currents to send their creations into the air.
Ask your camper: Why is it that hot air rises and cool air sinks? (Hot air rises because it is less dense, which allows it to “float” above the cooler air.)

Makey Lab – Morse Messages
Wireless communication is something that we use every day. But years ago, Morse Code was used to send messages. This form of communication was based on a series of dots and dashes that stood for individual letters and numbers which were sent by telegraph on radio channels. It was sent by whistle, buzzer, tapping, flags and many other ways! Using a buzzer and a button switch, campers recreated the original Morse code and sent each other secret messages to decipher.
Ask your camper: When listening to a sound code, how can you tell when a new word is starting? There are four seconds of silence between each word
Innovation Through the Ages – Day 3
Today in Innovation Through the Ages…..students began their exploration of the science of light and photography by making their own camera obscura out of paper. They also tested their own ability to see color and tried some color-correcting glasses to see if they improved their color vision, and then split light into its color parts using prisms and lenses!
In Engineering, students were challenged to research, design, build, test, and present a siege machine— a device that is designed to break or circumvent heavy castle doors, thick city walls or other fortifications in siege warfare. Our students came up with some fantastic designs, some that actually worked!
Ask your student to define/explain a camera obscura (a dark box (or even a very dark room) with a very small hole in one wall that lets in light. Directly across from the hole the image from the outside world will be projected onto the wall upside down)
