Geometry meets earth science as high schoolers investigate the cause and features of the four seasons. The effects of Earth's axis tilt features prominently, along with both the rotation of the earth about the axis and its orbit...

Given examples of modern terrorist attacks, learners discuss the characteristics of violent extremists and what measures are currently being taken to prevent attacks by such groups.

Every movement in the world can be measured and even motionless objects can be significant indicators of movement. Focus on motion graphs that feature distance vs. time, speed vs. time, and positive and negative acceleration.

Temper your excitement of temple geometry. Using algebraic and geometry concepts to determine various measurements in a circle diagram, scholars determine the shaded area of the diagram.

Take a seat on the parade route with a holiday-themed set of word problems. Young mathematicians answer questions based on the annual Macy's Thanksgiving Parade in New York City, including finding the average number of members in a...

Don't be resistant to physics! A simulation shows classes how a resistor works. Change the battery voltage and resistance to show how this affects the flow of electrons. Temperature and amps measurements are shown for the system as...

Apply geometric concepts to a design problem. Individuals examine the structural setup of the chain on a bicycle and use the measurements of the circles to determine the length of the chain. 

What would a baseball game look like on the moon? Probably a lot of home runs! A creative activity explores the motion of a projectile on the surface of different bodies in the solar system. Participants adjust the angle and...

Acute or obtuse? Seems right to me! As scholars explore the simulation, they investigate angle measures. Questions ask them to classify the angles using correct naming conventions.

In chemistry, the mole is a unit of measurement, much like a millimeter or liter. After learning about moles, scholars learn various equations relating to mass, volume, and concentration. They review each of these equations in a few...

Talk about a cool tool! Convert between units with the click of a mouse using a handy online resource. Enter the starting measurement and units for quantities such as torque, speed, and inertia, then sit back and relax while the computer...

The shortest distance from point A to point B is a straight line, but measuring distance gets more complicated when there are three points! Given the location of three friends, individuals determine the best point for all three friends...

Circles, circles, everywhere! Pupils learn all about circles, central angles, inscribed angles, circle theorems, arc length, area of sectors, and radian measure using a set of 12 lessons. They then discover volume formulas through...

An interactive challenges mathematicians to round large numbers with help from a large scale that measures the weight of a blue whale. The practie's five questions include multiple-choice, fill-in-the-blank, true or false, and an open...

Transform the classroom into a coordinate plane. Scholars walk along parallel lines drawn on a coordinate plane on the classroom floor. They measure angles and slopes and use the results to develop criteria that would make the lines...

Ramp up the study of slope. The class participates in a discussion about the physical aspects of stairs and ramps they encounter. Small groups work together and measure a staircase and corresponding ramp to calculate the slope of each....

Don't watch the resource go down the drain. Scholars perform an experiment where they measure the amount of water that flows from a funnel over time. They use the data to create graphs and find the curves of best fit.

Will the block float? Pupils take measurements to calculate the volume of various blocks of different materials. Using a scale, they determine the mass of each block and then calculate their densities. Scholars finish by ranking the...

How does GPS know where everything is located? Pupils read about satellites that are mapping the ocean and the question on how satellites know where they are. Readers discover the workings of the Global Positioning System and create...

It may take up less space, but the mass stays the same. Tackle a common misconception about conservation of mass using a hands-on lesson. Learners measure the mass of substances before and after melting, dissolving, and undergoing a...

Classes will definitely not be sinking after a buoyant instructional activity! A project-based assessment helps highlight the importance of prior knowledge as individuals design a floatation device for a cell phone. They use their...

The force will be with you during an inquiry-based lesson focused on friction. Young scientists explore the effect of different surfaces on friction. They use rubber bands to measure the amount of force needed to move an object on the...

Organic waste is a hot topic. The second of three installments in the Bioreactor Water Heating unit challenges pupils to create bioreactors that collect energy released from compost. After watching videos on the properties of water and...

Combine math and science with fun in the sun! Scientists build a solar gnomon using reusable materials to calculate relative air mass. Mathematicians measure the pole's shadow and use the data to solve for relative air mass....
