Do you separate your trail mix before eating it? Then you've been separating mixtures your whole life! Scholars model a contaminated soil sample using trail mix and estimate the percentage of each component. They consider how to clean up...

Let's go fly a kite ... oops, a paper airplane! The 13th segment in an aviation unit of 22 relates the parts of an airplane to paper airplanes. Pupils learn the functions of the control surfaces of a plane to really make their knowledge...

Now it becomes crystal clear why the unit is called Mixtures and Solutions. The fifth installment of a six-part unit explores mixtures and solutions. After viewing a demonstration on mixing pebbles with water, salt with water, and...

Young meteorologists examine the four main types of weather fronts and how they appear on a weather map. Participants learn about the difference between the types of weather fronts along with their distinguishing features. A...

You can breathe easily now that you've found a winning resource. Young biologists learn about the process of cellular respiration, primarily through teacher-led discussion and instruction. They also consider the concept of...

The Great Pacific Garbage Patch is one of several garbage patches around the world where garbage accumulates naturally. As part of a GIS unit that combines oceanography, environmental science, and life science, class members investigate...

Introduce your class to nanotechnology applications with three demonstrations that showcase scientific principles related to ferrofluids, quantum dots, and gold nanoparticles. Groups will work more closely with these applications in the...

Take two pills and call me in the morning. The first lesson in a short unit of four introduces class members to delivery methods of medicines. The instruction introduces the question of which delivery method is best to get you feeling...

So is that what you meant by rubber legs? The activity has pairs subject a chicken bone to vinegar and observe what happens over a period of days. Individuals then write up a lab report and document their observations and findings. 

The sun will continue to rise in the east and set in the west, no matter what. The first activity in a series of eight introduces the class to solar angles. It makes connections between a person's latitude and the angle of position of...

Get the class up and going with a lesson that discusses how airplane wings provide lift. Pupils use their knowledge of Bernoulli's Principle to develop an explanation of how it creates lift on airplane wings.

Did you know that there are over 200 different types of cells in the human body? One type, the stem cell, is the focus of the fifth of six installments in the Cells unit. The lesson asks the class to discuss stem cells and their...

What are the trade-offs when looking to get the most benefit from an energy source? Small groups compare the cost-to-emission levels of several energy sources by looking at the information graphically. The groups utilize this...

The energy is not really lost, it is just converted to a different form. Pupils learn about the conversion of energy in the fifth segment of an energy unit with six parts. Learners develop an understanding of the conservation of energy...

There's nothing sticky about the resource, unless you count the gumdrops! Scholars create a model of a lithium atom, complete with protons, neutrons, and electrons. It's just that these models are made with gumdrops and toothpicks.

Keep everything under control. The lesson, the 16th segment in a 22-part unit, provides a more detailed look at the parts of a plane, specifically the control surfaces. Pupils learn about the construction of the wings and the tails and...

Reduce the pressure in the classroom. The second instructional activity in an Airplanes unit of 22 introduces the class to Bernoulli's Principle. Pupils demonstrate the principle by blowing between different objects causing a reduction...

Do not let friction drag you down! The 11th segment in a series of 22 focuses on the fourth force acting upon an airplane—drag. Pupils learn about the effects and causes of drag.

Nothing says organization quite like a table. The third lesson in a six-part Mixtures and Solutions unit teaches young scientists about elements and the periodic table. They learn how the periodic table is organized and about the...

Plop, plop, fizz, fizz, oh that one is the fastest. The teacher demonstration is the second part of a four-part series. The class observes how different pill types dissolve in simulated stomach acid. They determine which one dissolves...

If you think you can do better, feel free to give it a try. Pupils learn about the work on Temple Grandin and consider ways to improve animal handling facilities. They work in groups to build models to showcase their ideas.

Are your household devices eating up a lot of energy? Pupils investigate household energy efficiency through a set of activities. They find ways to improve energy efficiency and reduce consumption. This is the 21st installment of a...
