Eighth graders complete seven work stations that highlight math activities while they focus on the rules for Internet use and classroom rules for working in cooperative groups. After completing the activities, they complete a self-...

Given a string of numbers and math symbols, learners take the challenge to insert parenthesis in the proper places to reach certain solutions. This is a challenge, indeed, an engaging enrichment for those who need a little more math!

Help learners use a variety of methods to identify, visualize, and simplify polynomials with like terms. Several different visuals are used to introduce the instructional activity, such as colored pencils, overheads, interactive white...

Here's an assessment task that's better than watching a show. Young mathematicians solve word problems involving multiplication and division with equal groups. They must find the total number of attendees on a trip to a theater based on...

How much land does a parcel hold? How much fertilizer does it take for a field of corn? Pupils answer these questions and more as they apply ratio reasoning and unit analysis. 

Let there be light. The last installment of a seven-part series has pupils conduct an experiment on light attenuation through different numbers of transparency sheets. They then relate the results back to how X-rays measure bone density.

Students explore how and why local convective, possibly severe, storms develop. They examine how hailstones form and the conditions under which they form. They test mock hailstones of varying sizes to investigate the impact and damage...

Population density, it is not all that it is plotted to be. Pupils analyze a scatter plot of population versus area for some of the states in the US. The class members respond to eight questions about the graph, specific points and...

Sugar cubes, collide! Groups design protection systems using bubble wrap to protect sugar cubes from being destroyed by falling batteries in the STEM lesson. They consider how the experiment relates to collisions in real-world...

Why do all sizes of pictures not show the same thing? Class members analyze aspect ratios of various sizes of photos. They determine which sizes have equivalent ratios and figure out why some pictures need to be cropped to fit...

After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

Young scholars examine the properties of lasers and research their types and uses.  In this laser instructional activity students view several demonstrations.

Students investigate the lure of snack-food advertisements to explain how snacks can fit into a healthy diet.

What happens next? Work on story sequence with a lesson that prompts kids to put a story back in order. Additionally, they discuss what would happen if one event was missing from the sequence.

Third graders investigate two mathematic scenarios and determine which is correct. They compare adding columns and places (such as the tens place, hundreds place, and so on) and familiarize themselves with how to add larger numbers.

Learners study the amount of potable water on the Earth. In this water instructional activity, students examine the amount of potable water as compared to all the water on the Earth. They discuss why many parts of the world do not have...

Primary graders develop strategies to assist them with addition and subtraction. They discover number combinations and numerical facts which enable them to add and subtract more effectively. Students use these techniques to complete...

Help third graders make sense of the Common Core math standards with this simple checklist. By rewording each standard as an I can statement, children are provided with clear goals to focus on as they participate in math lessons.

Students investigate how to draw and classify two and three dimensional figures (squares, triangles, rectangles.)

Students discover the types of stress that materials undergo. They examine how bridges and skyscrapers are built to withhold the tension. They create their own structure out of marshmallows and spaghetti.

Explore the concept of volume of prisms using an applet to perform the calculations. The link to the interactive applet is embedded into the lesson plan as well as a link to associated data sheets. Get your math class to the computer lab...

STEM scholars investigate sound attenuation by conducting an experiment in which they compare the farthest distance that they can hear a sound with and without ear protection.

Students define and compare/contrast abiotic and biotic factors presented while using web cameras on the Web World Wonders website.

High schoolers explore the basic building blocks of our planet.  In this minerals lesson young scholars begin the process of forensics on the basis of investigation and drawing conclusions from observations.
