Acid Rain Eats Stone!
Source Institutions
This display shows the dangers of acid rain on buildings and other structures as two concrete bunny rabbits are disintegrated by sulfuric acid. Learners scrape chalk onto the concrete bunnies.
Sticky Engineering Challenge
Source Institutions
In this activity, learners explore how engineers work in a team to solve problems.
Wind Tunnel Testing
Source Institutions
In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.
Clipper Creations
Source Institutions
In this activity, learners create a working model of a nail clipper. This activity helps learners learn the basic principles of simple machines, engineering design and model building.
Exploring Earth: Temperature Mapping
Source Institutions
This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.
Interactive Gumball Machine
Source Institutions
In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.
Leapin' Lizards
Source Institutions
In this outdoor activity, learners first explore lizard feeding behavior by creating a "lizard rig" to dangle different objects in front of live lizards and see which objects the lizards try to bite.
Balloon Bugs
Source Institutions
In this activity, learners make balloon models of disease-causing bacteria.
Infrared Investigations
Source Institutions
In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.
Hatch-a-Cyst
Source Institutions
What is the optimal environment for hatching brine shrimp? Using a scaffold, learners design and conduct experiments testing the effect of a single abiotic factor on brine shrimp cyst hatch rate.
Rock Cycle Roundabout
Source Institutions
In this activity, learners will learn how igneous rock, metamorphic rock, and sedimentary rock are formed as part of the rock cycle and that the same forces that produce/change rocks also produce/chan
Statue Display Tower
Source Institutions
In this activity, learners design, build, test and redesign a display tower that will meet a specific set of criteria and constraints.
