In this algebra worksheet, students apply the properties of transformation as they solve equations. They identify which equation is true and similar. There are 20 questions with an answer key.

Pupils perform simple experiments to show properties of enzymes through studying how apple sauce can turn into apple juice and experimenting with papaya seeds. Students witness how enzymes speed up reactions through witnessing the...

In this maximum and minimum problems activity, students solve and complete 9 various types of problems. First, they find two numbers with a given sum. Then, students find the maximum and minimum value of each equation. They also find the...

Name that shape! This simple worksheet has learners identify each geometric figure. They examine rectangular prisms, cylinders, rectangular pyramids, and hexagonal prisms. This one-page worksheet contains 8 problems, and the goals seems...

Students conduct a lab (with water, guar gum and sodium borate) and carefully record physical and chemical properties and changes throughout the session, and experiment with weighing by difference.

Learners define and discuss salinity, conduct classroom experiment to determine salinity of water sample by using hydrometer, record predictions, and demonstrate understanding of how salinity influences object's ability to float in water.

Students explore physics by conducting a class experiment. In this density lesson, students examine a list of items and discuss whether they will sink or float and then determine their density. Students examine the objects over five days...

Young scholars study Archimedes' Principle, flotation and the reaction of buoyant forces and explain the relationship between density and flotation.

Students explore models of density; wooden balls and marbles discussing whether they think the volume and mass are the same or different. They then compare the density of a loaf of bread that is squished and one that is not compressed.

Students identify the radius and diameter of a circle. In this geometry lesson, students calculate the volume and area of a cylinder and circle. They relate the circumference of a circle to Pi.

Students explain the importance of water in our daily lives. In this aquatic science lesson, students identify different ways to purify water and make it potable. They design and construct a water filter based on researched information.

Learners explore sources of  pollution runoff and actions that can be taken to reduce runoff.  In this pollution lesson students complete a worksheet and see why bio-essays may provide a more realistic picture of toxicity.

Students research the implementation of a research vessel used for ocean exploration.  In buoyancy lesson students will construct a device that shows neutral buoyancy.

Students examine a Webmath page, and demonstrate how to copy and paste. They create a computer-generated template page presenting the attributes of two- and three- dimensional shapes.

Students discover how salt water makes a pencil float better than freshwater by measuring and comparing the lengths of the portion of the pencil that floats above the water surface. They then determine if an unknown water sample is...

Students experiment with air. In this air instructional activity, students tape one end of a strip of paper down and blow on it. They place several items in front of the strip to see which items stop the air and which items the air can...

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.)

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...

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

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

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.

Learners relate the concept of density in relation to the rocks that make up the Earth. They determine the density of various rock specimens and answer assessment questions.
