What do skateboarding and baked goods have in common with math? You can use them to connect half-pipe ramps and cakes to arcs and sectors. Pupils compare the lengths of three different ramp options of a skate park. They calculate the...

No height? No problem! Learners use their knowledge and a little help from GeoGebra to develop the Law of Sines formula. The Law of Sines helps to determine the height of triangles to calculate the area.

Even though there is a wide variety of different triangles in the world, knowing a single equation allows us to find the area of each and every one of them. Follow along with this step-by-step presentation as Zoe clearly models how to...

Recreate the secret Coca-Cola formula in a virtual lab. Young scholars create the solution and then calculate sucrose concentrations in terms of percent mass, molarity, molality, and mole fraction. Then using density, learners...

Work, energy, and their relationship to power: what is the common thread? Explore this with your class as they learn the concepts of work and energy, both kinetic and potential, before completing multiple practice problems to...

Every knows that opposites attract! Here's a presentation that uses this background knowledge to explain magnetic fields and forces. The resource also explains the shape of magnetic fields and how to determine the direction of forces.

This can be used as a critical thinking exercise in congruence or as a teaching tool when first introducing the concept. Four octagons are arranged in such a way that a square is formed in the middle. With this information, geometry...

Review and use standard units of measure with your math class. They move from station to station estimating and measuring length, volume, weight, and area. At each station they estimate and measure, and then compute the difference...

Sixty multiple-choice chemistry questions make up this comprehensive exam used for the 2001 US National Chemistry Olympiad. Every topic that you would expect to approach in a general chemistry class is queried on. You could easily use...

Young scholars calculate the escape velocity of planets in our solar system and use that knowledge to calculate the escape velocity for NGC 2300 group. They then suggest reasons for the escape velocity to be higher than possible given...

Sixty multiple choice questions cover the entire gamut of chemistry concepts. This is the local section of the U.S. National Chemistry Olympiad, where your chemistry candidates take a shot at entering the national competition. They...

Proportions are ratios found using multiplication or division. Middle schoolers solve measurement problems, find a figure's missing dimension, and find the distance between two points. Resource features four lesson plans with detailed...

Pupils explore the relationship between area and perimeter of polygons.They measure the area and perimeter of regular polygons inscribed in a circle. Learners then discuss how as the number of sides of a regular polygon increase, the...

Students calculate the volume and surface area of each shape. In this geometry lesson plan, students use nets and other three dimensional polygons to create visuals of the volume of a shape. They define important vocabulary words...

Eighth and ninth graders calculate the volume of a rectangular prism and a cylinder. In this liquid volume lesson plan, pupils use formulas to calculate the volumes of cylinders and prisms and then they use water to determine the volumes...

Students practice measuring with formulas. For this measurement lesson, students complete an activity that requires them to calculate perimeter, area, and volume.

Young scholars explore how to solve any quadratic equation with a video about the quadratic formula. They then use the quadratic formula to solve a set of quadratic equations.
