Several times throughout history, groups of soldiers marching in rhythm across a suspension bridge have caused it to collapse. Scholars experiment with pendulums, resonance, and force to determine why this would happen. First, pupils...

Does standard deviation work for non-symmetrical distributions, and what does it mean? Through the use of examples, high schoolers determine the standard deviation of a variety of distributions and interpret its...

Learners calculate the pixel density of a specific cell phone using the concept of similarity. They use information from the cell phone's website to make their calculations and then compare their results to the posted information.

Sew up your unit on operations with decimals using this assessment task. Young mathematicians use given rules to determine the amount of fabric they need to sew a pair of pants. They must also fill in a partially complete bill for...

Customers often want ribbon around fancy cakes, but how does a baker know how much ribbon to buy? Scholars view a cake with multiple layers in different geometric shapes. They must figure the perimeter and circumference and add them...

Use a hands-on approach to exploring the concepts of related rates in your AP Calculus class. Individuals explore the effect of the rate of change on a variable related to a variable they control. After analyzing the data they...

Help learners understand that perimeter and circumference are one in the same. Learners apply their skills to determine the perimeter/circumference of triangles, rectangles, and circles. They then use the same strategy to find the...

Don't leave this task on the shelf — use it is assess middle schoolers understanding of patterns. Participants try to discover a pattern in the number of bricks and planks used to make shelves. They then match descriptions...

Make a class set of spectrum tubes by first purchasing some diffraction grating, and then constructing the tools with mailing tubes or shoe boxes. If you aren't up for assembling them, you could purchase prepared spectroscope kits. This...

If you need a way to assess the concepts in your physical science class, use an extended set of worksheets as a midterm or final exam. It includes questions about density, physical and chemical matter, speed and velocity, weight and...

Scaling needs to be picture perfect. Pupils use proportional reasoning to find the missing dimension of a photo. Class members determine the sizes of paper needed for two configurations of pictures in the short assessment task.

Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...

Help learners find joy in facing mathematical challenges. The questions posed on this worksheet encourage young mathematicians to utilize skills learned throughout a geometry unit, and to apply themselves and persevere through...

It's imperative to be as precise as possible. Future engineers learn about precision by building a cardboard machine. The base, corners, handles, and paddles must all be assembled with precision or the machine won't work.

Create trigonometric functions from circles. The first lesson of the module begins by finding coordinates along a circular path created by a Ferris Wheel. As the lessons progress, pupils graph trigonometric functions and relate them to...

This is a big project, but lucky for you, the materials, steps, and additional notes are at-the-ready to make it a classroom possibility. Your class will sculpt a life-sized artist using steel brackets, plywood, chicken wire, and...

Remind your middle school scientists how fox ear size varies depending on the climate they live in; large ears allow heat loss while small ears keep heat in. Discuss how a cold-blooded animal might try to regulate body temperature. Then...

Here is a worksheet that is almost a lesson! In it, learners conduct an experiment in which they determine the size of objects when viewed through viewing tubes. This resource has all of the instructions and tables necessary to complete...

Make your classroom interesting by teaching or assessing through tasks. Deepen the understanding of Geometry and motivate young mathematicians. The task uses investigation with tennis balls and their container to prompt learners to...

Out with the old and in with the new. Learners use a set of prices of computer monitors from 1994 to make a prediction. They then use one current price and what they know about the old prices to make a more recent prediction. Their...

A complete lesson on dividing whole numbers by other whole numbers and getting a fraction result. Groups of learners use fractions bars, and strips of paper that are cut to specific lengths. The hands-on activities in the lesson are...

Mass and density are difficult topics for kids to understand, and even more difficult when you have visual impairments or blindness. Learners will make boxes and fill them with cotton, sand, or crushed paper. They will feel the density...

Students experiment with reflections of two plane mirrors placed at a 90 degree angle to see what will be reflected.

In this Iditarod worksheet, students complete word problems about fractions, money, and more, based on the Iditarod race. Students complete 10 problems.
