How do Hypotonic, Hypertonic, and Isotonic Solutions Affect the Water Movement of a Cell?
After removing the shell from a raw egg, cell biologists soak the egg in either a hypotonic, hypertonic, or isotonic corn syrup solution. They calculate the percent change in mass and compare it to the strength of the solution in a...

Thirsty Rocks: Please "Porous" a Drink!
A simple activity goes a long way in demonstrating the property of porosity to your rock hounds. They will mass a specimen of dry sandstone and then soak it in a pre-measured amount of water. After seven minutes, they once again measure...

Kindergarten Observing, Comparing and Contrasting
Although this is a science instructional activity, it can be adapted to help meet Common Core standards in math as well. Starting scientists describe physical properties of objects and explore three forms of water. To address the Common...

Follow the Drop
Young surveyors look for patterns in water flow around campus. Using a map of the school (that you will need to create), they mark the direction of the path of water. They also perform calculations for the volume that becomes runoff. The...

Resonant Rings
Physical or earth scientists construct this clever contraption to demonstrate how size effects frequency. Several paper rings of various sizes are taped onto a board and shaken to create vibrations. The resonant frequencies are easily...

Get a Leg Up
Traveling through space is an amazing experience, but it definitely takes a toll on the body. After reading an article and watching a brief video, learners perform an experiment that simulates the effects of zero gravity on the human body.

Size It Up
The three types of rock aren't classic, punk, and hard. The chapter covers everything scholars need to know about rocks. Pupils compare rocks, learn about their formation, see how rocks change, and follow every step of the rock cycle....

Measuring and Comparing Mass With a Balance
Fifth graders observe and demonstrate measuring and comparing mass using a balance. They discuss the definition of mass and the units of measurement used, observe how a balance is used, and with a partner balance the baskets of the...

Phases of Charon
Charon, the largest of Pluto's moons, was discovered in 1978. Lesson is a walk through of how to solve for the phases of Charon. It uses two different points on Pluto and takes into account the tilt of the pole, the rotational axis, and...

Sorting Solutions
It's okay to play with your food—just this once! Scholars design and create meshes and chutes to sort pasta by size and shape. They test their designs and make improvements as necessary.
Science 4 Inquiry
All the Small Things
Scholars use sorting cards to try to define a pure substance versus a mixture. Risk becomes reward as they observe the differences and create a flowchart sorting matter into mixtures and pure substances (elements and compounds).
