Students view a right triangle displayed by the teacher. Students measure legs and the interior angles of the triangle. They look for a pattern or relationship between the legs and angles. Students use pegboards and string to create more...

Seventh graders divide into small groups to construct several models. Each group builds with an accompanying chart showing the colors of gumdrops used for the protons, electrons, and neutrons.)

Students define density and observe that things that are less dense than water will float. Students find the density of copper, iron and aluminum

Students prepare to take the GED by reviewing basic math concepts. In this geometry instructional activity, students review vocabularies such as formula, perimeter, circumference and other important geometric terms. They convert between...

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...

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.

In this moon worksheet, students calculate information about the crater that was created by a massive impact. This worksheet has 3 problems to solve.

Student describe porosity and permeability in sand, gravel, clay and potting soil. They experiment using different materials to discover the different porous substances and the permeability of the same substances. Students place data on...

Students observe the process of transpiration in leaves. They measure how much water a leaf gives off in a 24-hour period, calculate the volume, and answer discussion questions.

Ninth graders solve linear equations.  In this Algebra I lesson, 9th graders investigate the properties of equations (Reflexive, Symmetric, Transitive, Substitution, and Transformation Properties) and use these properties to solve...

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.

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...

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...

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

Tenth graders study the metric system.  In this metric lesson students complete a lab activity and several metric worksheets. 

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

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.

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 geometry worksheet, 10th graders respond to journal prompts related to prisms and classifying solid shapes.  The two page worksheet contains nine questions.  Answers are included. 

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

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.

In this chemical reactions learning exercise, students answer 20 multiple choice questions about chemical equations, chemical formulas, oxidation and reduction reactions and acids, bases and salts.

In this soap instructional activity, students produce soap in the laboratory and test their product by using it to wash away engine oil. Students answer four questions about tests they perform on their soap.
