Learn how insects have inspired engineers to make a robot that walks on the surface of water. Design your own water-walking critter using thin wire, and test its effectiveness: how many paperclips can it hold up using surface tension?
Watch an interview with a couple who built a home from shipping containers. Then, design and construct a scale model of a unique shipping container home using printed templates, and estimate the cost of flooring and paint based on model dimensions.
Perform an experiment to determine whether smooth or wrinkled fingers are better at holding wet objects. The experiment requires only a water bottle, paperclip, and plastic ruler.

In this activity, students will learn how to prepare deep well slides for observing two types of microorganisms called Paramecium (a group of protozoa, or single-celled organisms, which move with cilia, so they are called “ciliates”) and Euglena (microorganisms which move with flagella, so they are known as “flagellates”).
In this activity, students will observe three “mystery” mammal skulls and compare and contrast the features of each skull. Students will learn the anatomical terms for skull features such as orbits, nasal passages, and foramen magnum. Students will learn how these features relate to physical characteristics or behaviors of each animal. Students will use their observations and recordings to attempt to identify each skull, and will discuss how these physical characteristics helped the animal survive in its environment.
In this activity, students will research general information about bettas and use that information to determine suitable habitat requirements and maintenance. Students will work collaboratively to perform weekly maintenance duties to keep their betta alive. Students also will observe physical characteristics of their betta and conduct investigations on the behavioral characteristics of their betta.
Geologists are greatly interested in minerals because they can reveal an enormous amount about the history of the geologic environment in which they are found. Geologists can classify and identify minerals by observing various properties such as streak, hardness, luster and, in some cases, fluorescence. In this activity, students will examine 10 mineral specimens and explore the different properties that minerals exhibit.
