In this interactive activity from the Building Big Web site, use your knowledge of bridge design to match the right bridge to the right location in a fictitious city.

In this interactive activity from the Building Big Web site, investigate dams in distress and decide if they should be repaired, removed, or left alone.

In this video segment adapted from ZOOM, cast members make a bridge from a single piece of paper. Will it be strong enough to hold a hundred pennies?

In this interactive activity from the Building Big Web site, think like an engineer and use your knowledge of dome design to match the right type of dome to the right location in a fictitious city.

This series of 5 high-quality, standards-aligned, inquiry-based activities and two environmental STEM challenge activities have been field-tested by kindergarten students and families of Wequiock Children's Center for Environmental Science during Safer At Home orders. These activities encourage students to use natural areas around their homes and in their neigbhorhoods as they improve their science observation and reasoning skils as they explore the science of pushes and pulls in nature. The materials used are ones generally available at home and the activites require little preparation on the part of caregivers. Created as a part of a WISELearn OER Innovation project, Connect, Explore, and Engage: Using the Environment as the Context for Science Learning was a collaboration of the Wequiock Children's Center for Environmental Science and the Wisconsin Green Schools Network. One of the goals of the project was to create standards-aligned lessons that utilize the outdoor spaces of the school (as well as those of the students' homes).  Each section of this resource is an individual activity. While each activity builds on the previous ones, it is possible to use them individually.The title image was used with permission and is courtesy of Joe Riederer.

This video segment from IdahoPTV's D4K lists, describes and shows examples of the 6 simple machines and how they make work easier.

In this video segment adapted from ZOOM, the cast tries to design and build a bridge made out of drinking straws that will support the weight of 200 pennies.

This interactive activity, from the Building Big Web site, explores tunneling and the tools and methods used to do the job.
