Planning a party of 45 guests may be more complicated than it would seem.  Learners must design the space in accordance with these constraints about the space available in the room. They need to calculate area, circumference,...

Scientists discovered the first exoplanet in 1995 and by early 2018, they confirmed the existence of more than 3,700—that's a lot of data! As part of the PBS 9-12 Space series, scholars interpret data about exoplanets. They compare...

Winter, spring, summer, and fall—Earth experiences them all! But what about Mars? Scholars compare the planets in terms of distance, tilt, and rotation during a lesson from PBS's Space series. Great visual models of Earth and Mars, plus...

How do people transport fresh water long distances to ensure everyone has access to it? The final lesson in the 10-part Fresh Solutions unit encourages individuals to design their own solution, or solutions, to that very problem. Groups...

Bring the resource out from the shadows. Viewers of a short video learn about drive-in theaters and how operators project images onto a large screen. They then perform an experiment to determine the relationship between the distance of...

Enlargements make it bigger, right? A video shows viewers how to perform a basic dilation with a fractional scale factor. They learn how to use the scale factor to find the location of the transformed vertex by multiplying the horizontal...

Count on the scale to enlarge a figure. The video shows how to create an enlargement given a scale factor and a center of enlargement. The presenter multiplies the vertical and horizontal distance by the scale factor to find the new...

Cut it in half with a compass and straightedge! Using construction tools, a video shows how to create an angle bisector. The presenter points out what it means to bisect an angle in terms of the measure and distances from the sides of...

Use rectangles to find distances. Given a rectangle and three associated triangles, pupils determine the area of the triangles. Scholars know the three triangles have equal areas along with the perimeter of the rectangle and two other...

Half are real-world. The 2011 AP® Calculus AB free-response questions let pupils and teachers see how content appears on the exam. Half of the questions contain real-world context, and four items do not allow calculators. Real-world...

Commutive and associative properties are the focus of a five-question interactive. Dealing with decimal multiplication and addition, mathematicians solve multiple-choice and true or false questions using a model that moves balloons along...

How loud is the class's hearing threshold? Using a sound level meter, the class members observe how the loudness of sound is affected by distance. Learners continue to study decibels by seeing how different sounds compare to each other...

Take mathematics to the hoop! Pairs first measure the linear distances on a basketball court. Using those measurements, they determine the scale lengths to create a scaled model. To finish the activity, learners create models of the...

Leave all your travels needs to the math department. Pupils apply knowledge of triangles to identify a triangular path for a traveler to take. They use a given distance for the second leg of the trip and a constraint on the length of the...

A nanometer is the approximate distance your fingernail grows in one second. Hard to visualize, isn't it? The third of a five-part lesson on scale seeks to help learners understand the size of the nanoscale of measurement. Using examples...

Mint candies are good for more than just one's breath. Using basic materials such as mint candies, straws, index cards, and Popsicle sticks, scholars create race cars that meet a given budget as well as design constraints. They perform...

There are more ways to use mint candies than to just eat them. In groups, learners design and build race cars using mint candies, drinking straws, Popsicle sticks, index cards, and other materials. They decide on an independent variable...

No need to be an Einstein for this project! Clever crafters add their name, address, and country to three Einstein-themed templates and create their own, personalized stationary. A great way to stay connected while social distancing.

The corona virus pandemic is indeed a historic event. A time capsule activity permits young historians to document these days of social distancing, remote learning, and quarantine by collecting artifacts that capture what their lives are...

Just when is the universe's birthdate? Pupils use previously collected spectra data to find the redshift and radial velocity of supernovas. They then calculate the distance before finally creating a Hubble diagram. Finally, individuals...

Think bungee jumping looks scary? Knowing the science behind bungee jumping might make it less so. Using an egg and rubber bands, young engineers model bungee jumping. They test the distances that the egg falls for different numbers of...

It's important to know the final destination. Scholars first measure distances in a region of interest using a standard measuring device or by counting steps. They then use an appropriate scale and graph paper to create a map of the...

From outbreak to epidemic to pandemic. Calls for flattening the curve, social distancing, and face masks. A 12-slide presentation details pandemics and strategies for containment and mitigation of infectious diseases.

Eleven slides make up a presentation that details the importance of practicing social distancing and what can be done at home during the COVID-19 pandemic. Scholars take part in the classroom discussion highlighting topics such as...
