![]() Test out your popsicle protector by timing how long it takes for the popsicle to melt, or use a thermometer to measure how the temperature changes inside the container. Consider the size and shape of your container, and whether or not you will want it to be open or closed. Then decide which material you want to use for your popsicle protector. Which one melts the fastest? Which takes the longest? What conclusions can you draw from the results? Start by seeing how quickly an ice cube melts when left out on the kitchen counter on top of different insulators such as paper, metal, plastic, and foam. (Click on the video to learn about insulators.) Materials that limit heat transfer are called insulators. ![]() You’ll need to consider how heat moves (or doesn’t move) through different materials. Welcome to the Protect the Popsicle Engineering Design Challenge! Have you ever bought a pack of popsicles on a hot day only to find them melted by the time you got home? Your challenge is to design, build, and test a container that keeps a popsicle cold for the longest amount of time. Take your remaining two popsicle sticks and stack them on top of each other.Make a stack of 5 plain popsicle sticks all on top of each other.Pom poms, cotton balls, or other objects safe to use as projectiles.You can check out these titles on Hoopla for other catapult designs: Stomp Rockets, Catapults, And Kaleidoscopes and The Art of the Catapult. – How can you make sure that the rider of your parachute lands safely? Try designing a basket for your parachute.Ĭlick here to take this challenge to the next level. – Is the fall of the parachute affected by the size and shape of the rider? How so? – Which kind of material makes the best parachute? ![]() – How do different sized parachutes change how they fall? What about different shapes? While building, consider the following challenge questions: – Optional: Plastic or paper cups, scrap fabric or dish towel, hole puncher, cardboard. Experiment with different sizes, shapes, and materials to see how you can make your parachute fall the longest. Use household items such as plastic bags or fabric to design a mini parachute for a small object. Parachutes work by increasing the force of air resistance pushing up against gravity as something falls. Youll need to wrap the rubber band around several times to make it nice and tight. ![]()
