Melting Ice: Designing an Experiment
Sometimes, despite the best laid plans, the unexpected will occur. Learners witness this firsthand as they carefully design an experiment to determine the time needed for ice to melt in salt water or pure water. They uncover facts not...

Measuring Dark Energy
You're only 10 minutes late? Do you know how much the universe has expanded in those 10 minutes? Scholars graph supernovae based on their redshift and see if the results verify Hubble's Law. If it does confirm it, the universe is...

The Greenhouse Effect: Warming the Earth Experiment
First in a two-part lesson on the greenhouse effect, this lesson involves a classroom demonstration of the phenomenon, and a lab group experiment with color and absorption. Although there are easier ways to demonstrate the greenhouse...

Determining the Nature, Size, and Age of the Universe
Prompt scholars to discover the expansion of the universe themselves. Using photographs of other galaxies, they measure and then graph the size and distance of each. Finally, they draw conclusions and prove the universe is...

Supernova Chemistry
By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...

Exploring Buoyancy
Young scholars use materials found at a resource table to design simple devices that will house instruments to take water samples from a tub of water. They design 3 instruments, each varying in density so that one will float, one will...

Float or Sink?
Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...
Science Friday
Pinhole Viewer
Take a peep into optics. Pupils watch a video about a large Polaroid camera before building pinhole viewers. The scholars then create different types of viewers and compare them to determine which provides the best image.

Properties of Fresh and Sea Water
Middle schoolers work with three stations to demonstrate the properties of water. They explore water's boiling point, freezing point, and its ability to store heat.
Curated OER
The Nature of Salt
Young scholars record information from the periodic table for sodium and chloride. They determine whether salts are molecular or ionic compounds, along with sodium chloride's molecular weight, and relative weights

Equal and Opposite Thrust in Aircraft: You're a Pushover!
It's the law—every action requires a reaction, no matter how small. Pupils experience two demonstrations of Newton's third law of motion as it relates to thrust in the 10th segment of a 22-part unit on flight. Using their mathematical...
