Exploring Variables While Testing and Improving Mint-Mobiles (for High School)
Mint candies are good for more than just one's breath. Using basic materials such as mint candies, straws, index cards, and Popsicle sticks, scholars create race cars that meet a given budget as well as design constraints. They perform...

Evaporation
This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag...

Wetland vs. Stream Macroinvertebrates
A link to a comprehensive macroinvertebrate guide gives you the information needed to prepare for this field study activity. Sample macroinvertebrates are collected from areas representing different environmental conditions. Junior...

Solar Kit Lesson #11 - Power Maximum: An Electrical Determination
Collaborative groups connect resistors and solar panels in series and measure electrical resistance, voltage, and current. The objective is to order 16 solar panels from strongest to weakest. They graph current-voltage and power curves...

Celery Lab
How do sugar and salt affect celery's mass, width, and flexibility? Using simple household ingredients, young scientists will perform a controlled experiment to find out. The lab is scaffolded through a worksheet, but there are no other...

Who Lives in the Water? Stream Side Science
Andree Walker thought of everything when he wrote this resource. It includes a detailed list of materials and background information links for the teacher. In addition, it has procedures, a macroinvertebrate identification key, and tally...

That's Predictable - Stream Side Science
Research the impact that changes in biotic or abiotic factors might have on an ecosystem. Debate for or against the changes and take action in the community. This resource ideally follows stream studies that young ecologists may have...

Fun with Air-Powered Pneumatics
How high did the ball go? Engineering teams build a working pneumatic system that launches a ball into the air. The teams vary the amount of pressure and determine the accompanying height of the ball. An extension of building a device to...

Linear Modeling
An inquiry-based algebra activity explores real-world applications of linear functions. Scholars investigate four different situations that can be modeled by linear functions, identifying the rate of change, as well as the...

Consuming Cola
Caffeine affects your heart rate — or does it? Learners study experimental design while conducting their own experiment. They collect heart rate data after drinking a caffeinated beverage, create a box plot, and draw conclusions....
