The class gets to practice being a mathematician in ancient Greece, performing geometric application problems in the way of Eratosthenes. After following the steps of the great mathematicians, they then compare the (surprisingly...

Introduce youngsters to the important role shape and form play in art with this extensive collection of activities and projects. From teaching first graders how to create mandalas to engaging third and fourth graders in the design...

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...

Pairs use an online simulation to determine the epicenter and magnitude of an earthquake. Using real data about the earthquake's maximum S wave amplitudes, they then determine the magnitude. The resource provides a great career...

Which pulley system will give us a whale of a good time? Teams compare the theoretical and actual mechanical advantages of different pulley systems. They then form a recommendation for how to move a whale from an aquarium back to the ocean.

Help your fourth graders make cents out of fractions and decimals with this short word problem. After learning that dimes are one-tenth and pennies one-hundredth of a dollar, students write a fraction and decimal for a given number...

Long considered the symbol of safe harbor and steadfast waiting, the lighthouse gets a mathematical treatment. The straightforward question of distance to the horizon is carefully presented, followed by a look into the...

Learners are given a logarithmic function and its inverse exponential function. The task, which is to graph both compositions of the two functions, uses the inverse nature of exponents and logarithms to generalize about the properties of...

Individuals create a GIS data layer in Google Earth that displays information about where one might find seven different cryptids. The class members research to find data on cryptid sightings they can include in their data...

Discover how to program objects to move on a screen. In the second lab of a five-part unit, each learner uses block instructions to program a sprite to follow their mouse (cursor). They investigate how to use these same block...

Earthquakes can be frightening and dangerous, but being prepared can make a world of difference. Perform an earthquake simulation during which the class practices how to drop, cover, and hold on as you read a script...

Algebra learners must know how to use rational numbers to approximate irrationals. This resource asks participants to decide which number is larger without using a calculator. It makes a great exercise to use as a five-minute transition...

Let nature guide your engineering designs. By taking apart a flower, pupils learn about reverse engineering. They use the results to brainstorm designs for new products or ideas. This is the seventh installment of a nine-part Life...

There's nothing sticky about the resource, unless you count the gumdrops! Scholars create a model of a lithium atom, complete with protons, neutrons, and electrons. It's just that these models are made with gumdrops and toothpicks.

How do seeds get around? It's not like plants can control seed dispersal—or can they? Dig deeper into the amazing mechanisms of seed dispersal observed in tropical plants through interactives, a video, and plenty of hands-on data...

Study heart health and math in one activity. After measuring their resting heart rates by finding the pulse in their wrists, learners build a stethoscope to listen to their heart rate, and note the differences between the two methods.

A cell of another color is still a cell. Pupils color a cell to identify its structures in the fourth segment of a seven-segment series. Groups work together to build a three-dimensional cell membrane segment, which is combined with...

Time is growing short. Teams work together to identify physical properties of rocks in order to determine the properties that would best suit their cavern shelter design.

Visit the Magic Treehouse and take your class on a trip through time with a reading of the children's book Mummies in the Morning. Using the story to spark an investigation into Egyptian culture, this literature unit engages...

Create a personal tree. By visiting an exhibit at the National Museum of Mathematics, the resource introduces the idea of fractals. The exhibit takes an image of the person and creates a tree by repeating scaled images on the shoulders...

Water pollution is everywhere, and pollutants range from oil to fertilizers. Bring the concept to life by demonstrating the difficulties in getting particular pollutants out of water.

Finding the volume of a right rectangular prism is the focus of the resource.  Worksheet includes a drawing of a cube to help learners visualize the concept. Young geometers will learn that as the side length increases, so does the...

Positive or negative, zero or no solution, are all possibilities for the solution of a linear equation. Here the resource gives examples of linear equations in one variable and their type of solutions. The resource comes with commentary...

Teams use the design process to design, build, and test a model levee to protect the town from a wall of water. A handout provides a price list for the materials learners can use to build their levee within a budget.
