Build your bridge using only straws and clear tape. Before you build, you may want to sketch your design and test out shapes to see which are the strongest. For example, when you tape straw pieces together to make a square, should you leave the center empty, or add more straw supports in the center?
When you are satisfied with your bridge, place it between two tables or chairs that are space at least 9 inches apart. Place the cup in the middle and add a few pennies at a time. Count the pennies and keep adding them until the bridge collapses. How many pennies did it hold? How did the bridge break? Can you change your design to make it stronger?
The Museum of Science + Industry explains what is happening:
Look at a steel or wooden bridge and often you will see triangle shapes making up most of the bridge’s support structure. These are called truss bridges. Triangles are structurally the strongest shape because they allow weight to be evenly spread throughout a structure, allowing it to support heavy loads. Truss patterns are used in other structures as well, such as roofs, radio towers, crane arms, and more.

Exploring works of art helps children understand the world around them in many ways. Art gives kids an opportunity to talk about design (colors, shapes, lines) and learn about history and cultures through the art’s subject matter. Art appreciation can help younger kids describe what they see, learning to put their thoughts into words.
The Art Institute of Chicago has a fun way for families to explore works of art virtually with JourneyMaker. Choose from a variety of themes and artworks to build a custom art adventure with your family!
JourneyMaker is a digital tool that allows your family to create your very own tour of the museum. Choose one of eight storylines—like Superheroes, Time Travelers, or Strange and Wild Creatures—and then select works from the museum’s collection within that story. After you’ve made your selections, you can print out your personalized Journey Guide, which includes information, activities, and wayfinding directions. You can use your guide to take an actual tour of the museum (reserve tickets in advance), or just explore the artwork virtually.
Exploring the JourneyMaker website is one of the ways to earn the Art Badge in the Summer Reading Challenge. You have until August 31 to log all of your reading and activities in Beanstack! While you’re there, be sure to enter any tickets you have earned into the Grand Prize drawings of your choice.

Try looking for an ant colony on your driveway or sidewalk and setting up an ant experiment. Find different types of food such as crackers, sugar, or fruit. Break the food into small pieces and place it in different places near the ant colony. You can even make a hypothesis about what will happen and even which kind of food will be the ants’ favorite.
As they find the food, ants will let scent trails, called pheromones, down on the ground to guide other ants in the colony to where they can fine food. Once they’ve found the food, try placing an obstacle in their way and see how the ants react.
