Students identify the ratios of different triangles. In this geometry lesson plan, students identify the similarity and differences of triangles. They use the navigator to move the sides of the triangle around.

Seventh graders determine whether two triangles are congruent and provide an explanation to why they are not. They apply concepts of measurement of angles and collect evidence of congruent angles in the world.

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

The dynamics of a city can have a drastic effect on the weather. A hands-on lesson asks learners to build a model to illustrate how city pollution provides a nucleus for condensation. The greater the pollution, the greater chance for...

Students excavate an artifact. In this archaeology lesson, students get a bucket filled with dirt and a broken up artifact. They work in groups to take it out and to find what its purpose was. 

Students practice estiminating and measuring angles. After watching a short video, they identify angles in objects in the classroom and their homes. In groups, they participate in activities in which they are given a scenerio and are...

Young scholars explore the oceans from their origin. In this oceans lesson, students read and discuss excerpts from the Book of Genesis regarding the creation of the ocean. Young scholars then clean up a mock oil spill, measure the...

Students examine musical instruments as main part of the study of sound energy. In this designing instruments lesson plan, students focus on the elements of an instrument that cause sound to be created and design a unique musical...

Learners conduct their personal investigations into paper airplane flight. Cooperative teams are formed, with students choosing the paper airplane design that they are most interested in building.

Middle schoolers work cooperatively in small or larger groups to create a structure. They design and explain every aspect of the building. This is a terrific inter-disciplinary unit which students enjoy.

Students construct and maintain a school garden. In this gardening lesson, students plan the construction of the garden by writing letters to local businesses asking for supplies and materials; students build the garden using their math...

Learners discover stoichiometric relationships in chemical equations. They review mole to mole conversions. They understand mass/particle conversions. They perform a lab to reinforce stoichiometry.

Learners explore estimated and exact results for derivatives, tangent lines, implicit differentiation, and symbolic differentiation. The lesson provides examples with solutions and practice problems. 

Students track movements of ships, tugboats, and barges on the Hudson River estuary in order to practice addition and subtraction skills. They solve word problems by reading and interpreting data from a table. They calculate distances...

In this chemical reactions worksheet, students complete a crossword puzzle by figuring out the vocabulary words associated with 34 clues.

Students research the North American bald eagle to determine if this bird's characteristics make it an appropriate symbol to represent the United States as a country. They debate the substitution of other bird species for the eagle.

There are many different ways to show a proof of the Pythagorean Theorem.  Here is a nice hands-on paper cutting activity that shows a graphic representation. You can even challenge your young Pythagoreans to come up with their own...

Drop a perfect project into your lesson plans. Groups use different building materials to create models of parachutes for food drops. After testing out their prototypes, they make improvements to their designs.

Geometry is the study of how to use math to describe and investigate different points, lines and shapes. The way that a shape is described in geometry is with a formula, which is simply a mathematical way to calculate different...

This site offers games and lessons that teach basic math concepts such as area and volume, number patterns, time, etc. Games use familiar tasks such as shopping to reinforce math concepts. While the title of each page includes an English...

In this earth science lab, middle schoolers will find, identify, and create a visual presentation of the rocks that are found around their school. They will determine the mass, volume, density, color, texture, and hypothesize what each...

Provides a list of area and perimeter formulas for two-dimensional shapes and volume and surface area formulas for three-dimensional solids.
