Frequency polygons are a different way to represent frequencies over intervals. Pupils take frequencies for intervals of data from a frequency table and plot them as a frequency polygon. Budding mathematicians find information about the...

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...

Nanotechnology is described for emerging engineers. Instructions for converting nanometers to meters is provided. Finally, the step-by-step laboratory procedure for measuring the size of an oil molecule is walked through. What a terrific...

Students know that participation in sports requires energy. They comprehend that we get energy form the foods that we eat and the air thta we breathe. Converting food and air into usable energy is defined as celluar respiration. Students...

There are many different ways to show a proof of the Pythagorean Theorem.  Here is a nice hands-on paper cutting activity that shows a graphic representation. You can even challenge your young Pythagoreans to come up with their own...

A nine-page physics resource supports your lesson on acceleration. A step-by-step lesson plan walks you through the materials you need, the background information, steps for leading experimentation, and the explanation of the results....

For this subscription-based activity, algebra learners model changes in the length and width of a rectangle to determine the maximum area possible for a given perimeter and solve several application problems involving area, included in...

Now this lesson plan sounds fun! High schoolers throw a ball, film it as it soars through the air, and use a spreadsheet to collect data. A scatterplot is created to produce a quadratic regression equation, an equation in vertex form,...

Seven problems regarding gravitational pull are presented in this physics drill. Pupils solve for displacement, time, speed, and acceleration. Critical thinking and problem solving skills are both required to complete the assignment. 

Round and round we go! Pupils use reference angles to evaluate common sine and cosine values of angles greater than 360 degrees. Once they have mastered the reference angle, learners repeat the process with negative angles.

Can you use triangles to create a circle? Learners develop the unit circle using right triangle trigonometry. They then use the unit circle to evaluate common sine and cosine values.

Make an estimate by getting in line. The class works with scatter plots and lines of best fit to make an estimate for given values. Pupils determine whether there is a positive or negative correlation and draw a best-fit line. Using the...

Gardening geometers construct the formula for the area of a rectangle by viewing a video revolving around two young people, their lawn mowing business, and their need to charge by the square meter. A relevant real-life application activity!

The problem seems simple: find the area of the equilateral triangle whose sides are each length 1. In fact, this same problem is solved in 8th grade, addressing a different Common Core standard, using the formula for area of a triangle...

What happens to the momentum of an object when it strikes another object? Scholars roll a marble down a ramp so it collides with another marble. By measuring the speed of each marble before and after the collision, pupils answer this...

Learn about polymers while playing with shrinky dinks. Young scholars create a shrinky dink design, bake it, and then record the area, volume, and thickness over time. They model the data using a graph and highlight the key features of...

Due to the isolation of seamounts, their biodiversity offers a great deal of information on the development of biological and physical processes. Pupils use simple cluster analysis to rate the similarity and differences in biological...

Middle schoolers apply concept of ratio and proportion to determine length of Statue of Liberty's torch-bearing arm. They view video of Statue of Liberty, determine how long statue's arm would be if its nose measures four feet six...

Elementary schoolers are arranged in pairs and view the video Math Works: Measurement: The Difference Between Perimeter and Area. They discuss any prior knowledge they have of the term perimeter and then brainstorm together what the...

High schoolers solve five problems including finding the cross sectional area of two bodies, determining the swept out volume of a moving body, finding the average particle volume of a body and determining the collision time for a body.

In this geometry worksheet, 10th graders use the theorems regarding right triangles to find the missing length in a special right triangle. The one page worksheet contains eleven questions. Answers are included.

In this composite figures worksheet, students solve twelve short answer problems. Students find the area of figures composed of various polygons given a sketch of the figure with side lengths labeled.

The intent of this worksheet is to provide physics scholars with practice solving power problems. Seven different word problems are presented. Learners use formulas for energy and power to determine what it takes for boxes to be lifted,...

During a lesson on wave motion, physical science participants basically act out the waves as a group. Through their movements, the amplitude, speed, frequency, and wavelength are all identified. Ideas for modeling the reflection and...
