Week 1: Sun & UV Light
Welcome! We’re kicking off a summer of fun STEM activities by exploring the Sun and UV light.
The sun emits lightwaves of different kinds or lengths, and one kind is called ultraviolet, or UV. UV rays are invisible to the human eye and cause harm to our skin. We made keychains with UV sensitive beads. Hook this on your backpack for the summer, and when you see the beads change color it’s a reminder to make sure you stay safe by wearing sun screen.
Week 2: Paper Climbing Toy
Need to add the details of the activity here.
Week 3: Boats & Buoyancy
Why do some things float and some things sink?
Two concepts that we explored were buoyancy, which is the ability to float in water, and density, which is the degree to which an object is compact and solid. These were put to the test this week as we explored by designing our own boats.
We used a variety of materials to engineer our boats, experimenting with weight and design. Some floated, some sank, and some were “flinkers” — meaning they did both!
Can you build a boat at home that can be powered by the wind? Or a boat that can hold pennies and not sink?
This one is very long, is it too long?
Week 4: Inertia & Newton's Laws
Newton’s 1st Law states an object at rest will remain at rest, and an object in motion will remain in motion, unless a force acts upon it.
Place a card across the top of a cup and rest a penny over the center of the cup. Quickly flick the card away from the cup so that the penny drops into the cup. Why does this work? If you move the card quickly enough, the penny will stay at rest in the same spot, but then without support of the card, the force of gravity will pull the penny down.

Week 1: Catapults
Welcome! We’re launching a summer of fun STEM activities by exploring catapults. After exploring basic catapult design and the science of levers, campers built their own catapults and targets.
Week 2: Ziplines
A zipline is typically an inclined cable/rope that allows a pulley to travel along it. One end of the cable will be higher than the other, allowing the cargo to be moved by gravity from the top to the bottom of the cable.
Campers designed zipline carriages and tested various features to create the best delivery system.
Week 3: Buoyancy
This week we explored buoyancy, the ability to float.
Campers experimented with a variety of materials and built “flinker” boats – a boat that partially floats and partially sinks.
Week 4: Bird Beaks
Details will be added before thhis week of camp.
This new text box added without issue.
