Students see a demonstration of the concept of factors through modeling. They do an activity that help them explain further the concept of common factors and greatest common factor.

Students complete measurement activities. In this measurement lesson, students watch online clips about measurements. Students view items and discuss taking measurements of them. Students discuss what units of measurement and equipment...

Eighth graders create solutions with 5 different densities. In this chemistry activity, 8th graders analyze the density of solutions stacked on top of each other. They document their data through graphing. This assignment requires 4...

Students predict what is going to happen using prior knowledge being prepared to alter a view when faced with new evidence. They then accurately measure and record liquid volumes realizing that liquids and granular solids have...

Young scholars explore what happens to water as it goes from solid to liquid and back. In this state of matter lesson, students observe, measure, and describe water as it changes state.

Middle schoolers realize that density exists. They develop a mental model of density-to realize that something is going on that they cannot see to account for differences between materials.

Second graders read poetry and build their vocabulary through use of the puppet Geo George.

Students compare the size and shape of tubes that can be measured, to the size and shape of "nanowhiskers" that are too small to see. They practice measuring, calculating and graphing the ratio of circumference to diameter of a circle,...

Students practice converting metric measurements by completing the activities listed in this lesson. They first practice measuring common objects. They then convert metric measurements using the included worksheet.

In this thermometric titration activity, learners investigate the temperature changes when an acid neutralizes an alkali. High schoolers graph their results from the titration and draw the two best-fit lines on their graph. Where the...

In this geometry worksheet, learners solve word problems having to do with lines, angles, shapes, area, perimeter, and more. Students complete 57 problems total.

Middle schoolers design a simple boat and predict how much weight it can carry. They should also discover why objects float or sink and how this can be determined experimentally. A great instructional activity on buoyancy!

Students explore gases. In this chemical energy lesson, students will observer chemical reactions and infer a conclusion about reaction producing gasses.

In this three-dimensional shapes geometry lesson, learners identify geometric solids and name their properties. They define "face," "edge," and "vertex," and construct geometric solids using marshmallows as vertices and toothpicks as edges.

In this math worksheet, students solve six problems about 3D objects. Students also solve six problems about measuring 3D objects.

Students discover that scuba diving is more than a sport. It's a science that operationally integrates physics, chemistry, physiology, and oceanography. They perform a simple experiment which simulates the air tanks used in scuba diving.

In this math worksheet, students sketch the regions that give rise to the integrals. Then rewrite them as double integrals with the integration order reversed.

In this formulas worksheet, students transform and algebraically manipulate formulas for various variables.  There are 5 multiple choice questions.

Pupils investigate buoyancy, displacement and density.  For this flotation lesson students study the Archimedes' Principle, analyze data and draw conclusions. 

Students use conversion factors to solve problems. In this algebra instructional activity, students convert between Metric and English Units. They measure different objects and using both systems in their units.

A home improvement plan can help adult learners preparation for the GED exam. They review vocabulary, prepare diagrams, complete a worksheet, calculate perimeters and analyze how to approach a story problem. They identify many geometry...

Twelfth graders use Algebra and Geometry to solve a real life problem at the Zoo.

In this algebra worksheet, students calculate how many candy canes and ornaments are on each person's Christmas tree. They are given specific clues to help them calculate their answers. There are 2 questions with an answer key.

Students explore measurement and units. They measure eggs to determine their density, mass and percent composition. An inquiry approach is used for students to ascertain the mass.
