The political system of the European Union is historically unique and has been constantly evolving. To better understand the structure of the EU, class members compare the EU's branches to those of the United States Federal Government.

Infuse your unit on fractions, decimals, and operations with a thorough module about rational numbers. With a teaching guide, learner examples, templates for instruction, and lesson rationale, the module is a solid way to...

How do we clean up oil spills and other pollutants in the water? Explore water treatment strategies with a set of environmental science experiments. Groups remove oil from water, work with wastewater treatment, and perform a water...

How smart is that piece of paper? The activity introduces the idea of computer programming as a list of instructions written by computer programmers. Two individuals play a game of Tic-Tac-Toe in which one follows the commands...

Are wages based on race? On gender? Class members research wages for workers according to race and gender, create graphs and charts of their data, and compute differences by percentages. They then share their findings with adults and...

Young programmers investigate the Single Source Shortest Path problem by working in paris to devise their own algorithm. They then progress to using Dijkstra's Algorithm to solve the problem. 

Let's see how complicated we can make this simple task. The last activity associated with a 10-part series has groups design and build a Rube Goldberg machine. Teams determine a simple task to accomplish and use the engineering design...

To get the word out that the Great Pacific garbage patch (GPGP) contains millions of pounds of non-biodegrading plastics, individuals research the GPGP and write an article for a newsletter. Researchers present their facts in a...

Create trigonometric functions from circles. The first lesson of the module begins by finding coordinates along a circular path created by a Ferris Wheel. As the lessons progress, pupils graph trigonometric functions and relate them to...

Let your use of the resource be in proportion to its usefulness. Pupils investigate similar triangles by measuring side lengths and considering given angle measures. The results of the investigation help develop generalizations about...

One is chance, two is a coincidence, three's a pattern. Scholars must determine similarities and differences of a regular hexagon undergoing dilation. They look at lengths, angles, areas, and symmetry.

Put the better archer in a box. The performance task has pupils compare the performance of two archers using box-and-whisker plots. The resource includes sample responses that are useful in comparing individuals' work to others.

Young scientists study light reflection and refraction as they determine the critical angle, the rainbow angle, and color separation in rainbows. Teams record the data they collect in a shared spreadsheet and discuss results with the class.

Is the sun the only celestial body with magnetic fields? A guided discussion on the weather in space is designed with a mix of questions, discussions, explanations, and applications. Additionally, the resouce includes an...

Young scientists present their experimental designs from the previous experiment. The ninth activity in the series outlines what learners should present, what class discussions should happen, and the solution NASA came up with for the...

Researchers use scientific data to understand what is inside each of the planets. The first in a series of six, this activity builds off of that concept by having pupils use a data table to create their own scale models of the interiors...

All of the gas giant's atmospheres consist of hydrogen and helium, the same gases that make up all stars. The third in a series of 22, the activity challenges pupils to make scale models of the interiors of planets in order to...

Earth is 149,600,000 km, or 92,957,130.4 miles, from the sun. Young astronauts create an interactive model to learn the distances between planets. Nine groups, each representing a different planet, are spread around at class-calculated...

The role of women in the early film industry, both on screen and behind the scenes, is the focus of a resource that asks class members to analyze movie posters and DVD covers from the 1910s and 1920s. Using examples drawn from the...

Take learning outside and start classifying grasslands. Young ecologists observe grassland plants in order to classify them into the appropriate species by family. They note their characteristics and where they grow. A true...

Evidence shows the Vikings likely navigated by using a simple sundial to find their course. Videos, a short story, and discussion help bring this time period to life as they study European history with a hands-on experiment. Scholars...

While all light travels at the same speed, each color in the visible light spectrum contains a different wavelength and frequency. Scholars determine the relationship between frequency and wavelength as they complete the activity. They...

How do seeds get around? It's not like plants can control seed dispersal—or can they? Dig deeper into the amazing mechanisms of seed dispersal observed in tropical plants through interactives, a video, and plenty of hands-on data...

Need an a-maize-ing lesson to show your class how regulatory genes work? If you use the well-written resource, they'll be all ears! Biology scholars discover the gene responsible for the evolution of the modern-day corn plant through a...
