Can 100% Renewable Energy Power the World?
6 mins 6th - 12th CCSS: Adaptable
If renewable energy sources are the best option, why aren't they used on a global scale? Junior environmentalists explore the benefits and problems associated with energy sources such as solar, wind, and biomass with a short video and...
Hydrophobic Surfaces—Deposition and Analysis
9th - 12th CCSS: Adaptable
Couches, carpets, and even computer keyboards now advertise they are spill-resistant, but what does that mean? Scholars use physical and chemical methods to coat surfaces with thin films to test their hydrophobic properties. Then they...
Shedding a "Little" Light on Cancer Surgery
10th - 12th CCSS: Adaptable
Many types of cancer treatments now depend on nanotechnology—a big "little" discovery. Scholars begin by removing "malignant" tissue from simulated brains, one using fluorescent markers thanks to nanotechnology and one without. This...
Evaluating Sensors and the Impacts of Physiological Stress: Designing a Wearable Device for Rescue Workers
6th - 12th
New ReviewA long-term project has scholars consider ways in which sensors help monitor physiological stress levels of rescue workers. They design and create a portable device for this purpose. Techies to the rescue!
The Effects of Colloidal Silver on Microbial Growth: Investigating Snake Oil Science
9th - 12th
New ReviewCan your classes solve the problem of the smelly sweat sock? Young scientists complete a lab investigation that begins by using electrochemistry to generate colloidal silver. They use their solutions to test the rate of microbial growth...
Silver and Bandages: Assessment of Inhibition of Bacteria by Silver Colloid-Impregnated Bandages
9th - 12th
New ReviewSilver: more than jewelry, it's also a natural antimicrobial agent. An inquiry-based lesson asks collaborative groups to design and implement an experiment to test this property. Using samples of silver nanoparticles and a strain of...
Lab 2: Nanocatalysts Clean Your Car Emissions
9th - 12th
New ReviewSurface area certainly surfaces as a variable for chemical reaction rates. Scholars perform an experiment to discover how the size of catalysts affect the rate of a chemical reaction. They record their results in tables and graphs to...
