Do all lunar eclipses look the same? Find out in an activity where astronomers use the Danjon Scale of Lunar Eclipse Brightness to describe the color and brightness of the moon during an eclipse. Explorers make three observations using...

Measuring the diameter of the sun may get a little heated, but using an indirect approach can help individuals keep their cool. Learners use the reflection of the sun to measure how long it takes for it to move one diameter. Using the...

How do computers sort data lists? Using eight unknown weights and a balance scale, groups determine the order of the weights from lightest to heaviest. A second worksheet provides the groups with other methods to order the weights. The...

Learners investigate the relationship between the Fahrenheit and Celsius temperature scales. Given two data points, they construct a linear function to describe the relationship, find the inverse of the function, and make observations...

On your mark, get set, GO! The class sprints toward the conclusions in a race analysis activity. The staggered start of the 400-m foot race is taken apart in detail, and then learners step back and develop some overall race strategy...

Using the natural pH indicator of red cabbage juice, groups determine the pH of different everyday liquids. As they work, pupils gain an understanding of pH that may help deal with contaminants in the water supply. 

Verify the rule of thumb for finding the time of death. The project-based learning task asks pupils to determine when the rule of thumb process of finding the time of death is appropriate. Learners develop a function for the rule and...

Is there a relationship between hand span width and height? Statisticians survey each other by taking measurements of both. A table that can hold data for 24 individuals is printed onto the worksheet, along with questions for analysis....

How many visual models can be used to show multiplication? Three basic kinds of models can be used to represent and explain the equation 4 x (9 + 2).  The commentary section provides description and graphics to explain the set...

The single question in this activity has multiple ways to be solved. Two boys ran a mile. Their times were similar, except one time was a fraction of the other. Who ran faster? In demonstrating the answer to this problem, upper graders...

At the end of this activity, your number crunchers will have a better understanding as to how to describe graphs of velocity versus time and distance versus time. It is easy for learners to misinterpret graphs of velocity, so have them...

What symbols represent you best? Individuals consider how they would draw peers using symbols about their identities with an interview and art activity. After conducting interviews and portraits, the art makes a great centerpiece for...

When you look at me, what do you see? Young learners answer this question by creating a portrait that reflects the identity of one of their peers. First, class members create interview questions. Then, they interview classmates to...

Eighth graders read the book The Outsiders for understanding. They develop arguments, with support, for six assigned debate points. They write a position paper based on six debate points. The dress up as a character in the book and...

Creating an artifact that is representative of a specific time period provides an opportunity for amateur historians to understand the importance of primary sources. This resource describes the process for students to explore original or...

Symmetry, line, shape, art, and math are all connected through a fun hands-on craft. Included are instructions to a classic activity, where learners create butterflies to show symmetry in nature and then discuss symmetry in math. It is...

Learners rewrite a general quadratic function by completing the square to see a new form of the function that more easily identifies the x-coordinate of the vertex and the two roots of the function.

Your learners will write quadratic functions whose graphs include specific points and explore how these graphs are related to each other.

This activity asks learners to interpret data displayed on a graph within the context of the problem. Students are given three graphs that show solar radiation, or intensity of the sun, as a function of time. They are also given three...

Students learn and practice how to find the perimeter of a polygonal shape. Using a ruler, they measure model rooms made of construction paper walls. They learn about other tools, such as a robot, that can help them take measurements....

A survey of math graphing techniques includes horizontal and vertical shifts, stretching, lines of symmetry, even and odd functions, and absolute value functions.

Students input a function in either y= of f(x)= form, and then the site from WyzAnt does the rest! A detailed graph is shown in less than a second. Students can change the window used to view the graph as well as whether to have...
