Bathymetry is not a measure of the depths of bathtubs! Through the three lessons, scholars explore two different types of maps and how they are made. The resource focuses on topographic and bathymetric maps and teaching the techniques...

Why do rocks break down over time? Learners explore this concept by simulating physical and chemical weathering of different types of rocks. They use an abrasive to demonstrate physical weathering and acid to demonstrate chemical...

Subtracting fractions with unlike denominators is the focus of an interactive designed to boost mathematicians' problem-solving skills. Five questions challenge participants to answer multiple-choice and true or false questions with help...

Just who was Clara Barton? Using an archive photo from the National Archives, class members consider the legacy of the founder of the American Red Cross. The activity includes the photograph, along with prompts to help young scholars...

Now that geometers know how to solve for square units, can they solve for cubed units? Explore this concept as scholars examine four cubes to solve for volume in each. A detailed example explains this process, but you may consider asking...

Help your pupils find a pattern of direct variation. Young scholars use input-output pairs to find a constant of variation and then write the equation. As they build their equations, the interactive lesson provides feedback.

How does the purpose of a fiction book differ from the purpose on a non-fiction text? Model for your young readers a scenario in which each kind of book might be useful or fun to read and show examples of each genre. A list of suggested...

No more beating the pavement to find a virtual model of the human heart. See one in continual real-time motion, and layer it to highlight electrical impulses, blood flow, and valve activity. 

Ride to success in understanding systems of equations. Scholars graph a system of equations on the cost of a subway and a taxi using an interactive. Using this graph allows users to answer some questions about the situation.  

Commutive and associative properties are the focus of a five-question interactive. Dealing with decimal multiplication and addition, mathematicians solve multiple-choice and true or false questions using a model that moves balloons along...

View attractive, three-dimensional models of an animal cell, a bacterium, or a plant cell. Suspended in a translucent, undulating cytoplasm, are all of the major organelles for life science learners to examine. They can zoom in, click on...

Designed to promote disability awareness and sensitivity, the five lessons and activities in this packet provide class members with information about disabilities, and with models of behaviors and language that help to break down...

Thanks to Gary Paulsen's Hatchet, teen readers now know it's possible to survive in the wilderness. A study guide for the novel discusses common topics and vocabulary words found within the text. Additionally, readers get the chance...

Finalize the plans before playing in the sand. Learners design sandcastles using geometric and composite figures. They create blueprints, including the scale, and three-dimensional models of their castles. Finally, scholars calculate the...

Analyzing arguments is key to critical thinking. Colorful slides teach viewers how to recognize the structure of an argument, the claims, and the validity of the evidence used to support an argument. Then, provided scenarios permit...

A complex question looking for the total cost of a stained glass window by calculating area and circumference of a circle. With detailed components, this activity will challenge your designers to figure out if they have enough money to...

Have your class demonstrate their ability to compare fractions with this short multiple-choice assessment. Using the fractions 9/8 and 9/4, the students first make comparisons using both words and the greater than/less than signs. Next,...

Challenge your class with an amazing set of ideas that really put the project back into project-based learning. It all starts with a whole class research task. Each learner will look up and take notes on multiple facets of things that...

After determining the volume of various drinking glasses , class members evaluate sample responses to the same task to identify errors in reasoning.

Sea ice contains 17 sub-types based on age and various characteristics. Scholars observe ice floating in a simulated ocean and record their observations. Then, they view photographs of different types of sea ice and learn to...
