Do flexible circuits change dimensions during fabrication? Groups use GeoGebra software to measure the length of pictures of flexible nano-circuits. To determine if the circuits change dimensions, future engineers use Microsoft...

Given a box of certain dimensions, young mathematicians must determine if a box that is twice as big, actually holds twice as much. This is a brain-teaser of a problem. The worksheet provides a handy table that has learners calculate the...

What happens to a volume when you scale the dimensions of a rectangular prism? In this problem, a box of clay is increased in each dimension, with the intent to see if learners can generalize the result. The addition of...

Take the resource out of the file cabinet. Young mathematicians estimate the number of sticky notes it would take to cover the surface area of a file cabinet. They answer a set of questions on how the number of sticky notes would change...

Three activities make up a solar system lesson that features the sun, its light, and the shadows it produces. Scholars step outside to discover the changes shadows make at different times of day, take part in a demonstration of...

Here you will find a model of a linear relationship between two quantities, the water depth of a channel and the distance across the channel at water level. The cross section of the channel is the shape of an isosceles trapezoid. The...

Tip the scale in your favor when learning about scale factors. After viewing a video clip of a learner trying to determine the scale factor of the areas of two rectangles, scholars consider how changing the dimensions of a rectangle...

Here's a resource that models rising water levels with a linear function. The task contains three parts about the level of water in a cylinder in relationship to the number of golf balls placed in it. Class members analyze the data and...

Any vintage video game users in the room? Young scholars use a video presentation to analyze patterns in pixel arrangements. By writing an arithmetic sequence, they make predictions about the size of the image.

The shortest distance from point A to point B is a straight line—or is it? Young scholars determine the shortest route either along a circular path or through the center of the circle. Learners gain a unique perspective on arc length and...

Keep playing with those old toy cars! Pupils estimate the number of toy cars in an art installation. The only information they receive is a picture showing the toy cars arranged in concentric rings and the diameter of the overall...

Tackle some big questions about A Wrinkle in Time by Madeleine L'Engle with a board game project. As learners brainstorm for and complete their board games, they consider what helps and hinders Meg on her journey and why she succeeds in...

Around and around you'll go! Learners analyze the periodic nature of a Ferris wheel. Using a trigonometric function, they make predictions about the location of a specific car at the end of the ride and its total trips around the circle.

Young astronomers follow a step-by-step procedure for dividing a lump of dough into parts, resulting in a scaled volume set of puny planets. Along with the printable directions is a template chart of planet names on which learners can...

In this activity, students discover the relationship between a change in the dimensions of a rectangle and the change in the corresponding area.

This program simulates a particle connected to an anchor by a damped spring in two dimensions. Try changing the initial settings.

One piece of Play-Doh can make many different shapes. Even though you can change the shape by squishing or stretching the Play-Doh, it is still the same size unless you add or take away some of the dough. Try this experiment to test how...

This is an engineering activity that requires students to build a mousetrap car based on certain constraints. Constraints include students having a virtual budget that they use to buy approved parts for their car, the car having...

Using the USA TODAY Infograph, 'Wing tabs save fuel', ratios and proportions will be used to explore the concept of similarity between a drawing/model and the actual dimensions. The effects of dilation (size change) on an image and...
