Have fun while building the number sense of young mathematicians with this list of ten-frame learning games. From developing cardinality and counting skills to learning place value and basic addition strategies, ten-frames are excellent...

Over a span of two weeks or more, mini meteorologists record weather-related measurements. What makes this particular resource different from others covering similar activities are the thorough details for the teacher and printables for...

What's the least number of colors needed to color a U.S. map? The lesson begins by having pupils view a video clip on continuous and discrete phenomenon, then launches into an activity reminiscent of Zeno's paradox. A separate video...

How do you find the measure of an arc? Learners first review relationships between central and inscribed angles. They then investigate the relationship between these angles and their intercepted arcs to extend the Inscribed Angle Theorem...

Should we continue to spend money on nanotechnology? Groups engage in a problem-solving unique process around the newly emerging research field of nanotechnology. In order to propose a solution, the groups must research nanotechnology...

Mass and density — aren't they the same thing? This activity has groups use balance beams and water displacement to measure several objects. The pupils use the measurements to calculate the density of the objects. 

Back to the basics (of surface tension). The first installment of a nine-part series teaches young scholars about the basics of surface tension and how it relates to water droplets. They also learn how this concept allows for the...

Winning a spin game is random chance, right? Pupils create a table to determine the sample space of spinning two spinners. Individuals determine the probability of winning a game and then modify the spinners to increase the probability...

Help plan a road trip with linear equations. Scholars consider two different rental car companies and write equations representing the cost for each company. They graph the system of equations to determine the conditions under which each...

Prove the Law of Conservation of Mass through a lab investigation. A well-designed lesson asks groups to combine materials and monitor indicators for chemical reactions. Measuring the mass of the reactants and products allows individuals...

We know plants assist in the water cycle, but how do plants get water from the ground into the air? Through a series of demonstrations or labs, scholars observe the movement of water through plants. They microscopically view the cells...

One of the most diverse environments on Earth is the ocean. Young scientists explore the living things found in the ocean during an exciting seven-lesson unit. Their study includes organisms from plankton to invertebrates...

Students practice moving different shaped objects through a series of transformations. In groups, they discuss other ways to manipulate the figure to achieve the same results. They solve multiple story problems in the same manner.

Students discuss prejudice around the Martin Luther King, Jr. holiday. They use brown and white eggs to discover that they are both the same on the inside even though they look different on the outside.

Eighth graders analyze lyrics from songs from a variety of genres. In this musical analysis instructional activity, 8th graders write an essay about their life plans in which they discuss the lyrics of U2's song, "One." They tell how the...

Students understand the roles of animals in entertainment and sports. In this animal welfare lesson, students recognize that some animals are used humanely and others are used cruelly. Students classify different animals into the lists...

Students use complementary media to fill up the art space with repeated shapes. They use a water and wax technique to manipulate the surface of the artwork.

Students understand that most substances may exist as solids, liquids, or gases depending on the temperature, pressure, and nature of that substance. This knowledge is critical to understanding that water in our world is constantly...

Students are introduced to and experiment with the basic concepts of plate tectonic theory as well as assess the history of the theory of plate tectonics. They explain and illustrate the basic concepts through diagrams and models of...

Students use unconventional units of measure to estimate and measure.

Strict habitat requirements are needed for the survival of fish populations and fish variety in the Great Lakes. Young scientists become experts in the basic needs of fish and understand how survival necessities can vary with different...

Students examine the roles of those in Parliament. In this British government lesson, students participate in a mock election and conduct research regarding the difference between Parliament and government. 

Students use candy bars, beef jerky, and brownies to represent different fractions. Students also use colored multi-link cubes or blocks to illustrate the same representations of fractions. Students work with a partner to create diagrams...

From more empathetic individuals to greater tolerance in government, learners explore the benefits of a culturally diverse world through a series of collaborative, discussion-based activities.
