Some of the CO2 emitted by burning fossil fuels is removed from the atmosphere by natural sinks, such as the ocean. The fifth engaging lesson in the series of 21 examines the CO2 data from three very different locations. It then makes a...

Desert regions are hotter for multiple reasons; the lack of vegetation causes the sun's heat to go straight into the surface and the lack of moisture means none of the heat is being transferred into evaporation. This concept, and other...

The average American will move 12 times, which results in a lot of moving furniture! Class members consider the forces required to move objects with a creative simulation that opens with the forces required to push a filing cabinet....

"But still try, for who knows what is possible." - Michael Faraday. Faraday's advice features in a simulation that permits pupils to play with a bar magnet in order to make a light bulb glow connecting electromagnetic induction to...

Is the ice cooling down the water or is the water melting the ice? Here is a simulation that explores thermal energy transfer with iron, brick, and water. It demonstrates the flow of energy and what happens when each material is either...

We all have standards and scientists are no exception. Presentation covers standard temperature, standard pressure, temperature conversions, and absolute zero. It explains pressure using pascals, mm of mercury, atmosphere, and torr, then...

There are an average of three human fatalities by bears in North America every year, which is low when you compare it to the 26 killed by dogs and the 90 killed by lightning annually. The lesson encourages researching human-bear...

Grizzly bears can be up to 600 pounds and require a great deal of food, especially to survive hibernation. Comprised of multiple games, the third lesson of five only uses one setup. Pupils run around a large field, sorting and collecting...

The Clark's nutcracker bird hides seeds in 25,000 different sites every year to save for winter. Lesson demonstrates how difficult it would be to find these seeds months later when they need them for food. In the first of five lesson,...

I'm so cool! No, you're exothermic. This thermodynamics lab unit includes an introduction, teacher demonstrations, six labs that students rotate through each class day, homework assignments, application of knowledge, and...

Learners formulate new applications for simple machines in an original invention that solves a common problem. They brainstorm ideas for a new product using simple machines and communicate a finished project through an oral,...

Though the walrus spends roughly one third of its time on land, it eats organisms that live on the bottom of the ocean. The first in a series of five, the lesson uses a variety of plant and animal cards to have scholars build an arctic...

How do greenhouse gases impact temperature? Have your classes use the interactive software to explore different concentrations of greenhouse gases and their effect on climate. Learners can recreate different atmospheric concentrations...

Climate change isn't just about a warming planet; it will affect humans' health, spread of disease, changes in heat waves and droughts, and changes in storms and wildfires. Participants explore global climate change through discussions...

The sound waves of thunder are made when lightning very quickly heats the air surrounding it, expanding faster than the speed of sound. Learners explore waves through their own movement of string or set waves to constantly oscillate....

Beer's Law can be used to measure the concentration of certain compounds in samples of food. In the concentration simulation, particpants change and measure the concentration of different solutions by manipulating various types of...

Just like the old saying goes, "What goes in must come out." This simulation allows pupils to balance chemical equations. The introduction gives three examples before scholars switch to game mode, pick their level, and continue to...

Why does soda fizz when opened? Learners discuss the appearance of bubbles in soda bottles when opened. In groups, they design and complete an experiment comparing the amount of carbon dioxide dissolving in cold versus hot liquids.  

All synthetic materials began as natural materials. An engaging lesson begins with a hands-on activity and an example of the type of research that scholars perform independently. Then pupils receive a topic and begin researching the...

Construction leads to habitat loss and local wildlife suffers. Scholars must build a reptile egg incubation device that meets many constraints. Various experiments help them discover the chemical reaction needed to reach...

Can your breath change the acidity in a liquid? A lesson begins with a demonstration that proves it can. Then scholars perform an experiment to determine if other gases can change the pH of liquids. Finally, they research how this...

Most things naturally strive for balance, and acids and bases are no exception. Neutralization of acids and bases allows scholars to explore the color changes associated with the pH scale. After this exploration, pupils neutralize two...

Did you know strong bases can feel slippery and slimy? Lesson allows scholars to practice using the pH scale to identify acids and bases and their strengths. By changing the concentration of an acid and a base, they create the entire...

If you discover an unknown powder, how do you determine if it is safe? Lesson uses four different tests to identify the properties of various powders that appear the same. Then scholars get an unknown powder and have to determine which...
