How many different interpretations of the mean are there? Scholars place numbers on a number line and determine the mean. They interpret the mean as the average value and as the balance point.

Augment your math curriculum with posters detailing several concepts important to second grade math. Each poster features one math term from geometry, measurement, probability and statistics, computation and estimation, numbers and...

Get things moving with this elementary science unit on simple machines. Through a series of nine lessons including teacher demonstrations, hands-on activities, and science experiments, young scientists learn about forces, motion,...

Young scientists create a simulation of Hubble's law. Introducing the Big Bang Theory using balloons and a simple lab worksheet, scholars complete a data table and perform analysis.

Give young scientists a new appreciation of fresh, clean drinking water. After learning about the ways astronauts recycle their air and water, your class will work in small groups creating and testing their very own water...

Scientists use ice core samples to obtain temperatures of the earth from 400,000 years ago! The third of five lessons instructs pupils to interpret historical climate data to see changes over time. In part I, participants interpret...

How much time does it take to jump over three balloons? Pupils calculate the speed of tasks that require different motions. They determine motions for tasks such as walking, skipping, hopping, and jumping before creating a...

The Law of Conservation of Matter can be complex for young scientists to fully grasp. Use this experiment to help simplify the process as pupils perform two experiments to determine mass: one that melts a substance and the other that...

Young scientists get the chance to dissect pellets "owl" by themselves to determine the owls environment and nourishment. This is the third part of a three-part series. 

How does radiation affect our daily lives? Answer that question and others with a lesson that discusses radiation and its use in thermal energy transfer through electromagnetic waves. Pupils investigate vaporization and...

Scholars explore triangles with rods of different lengths. Using rods of 2, 4, 6, 8, and 10 cm class members build as many different types of triangles as they can. They also describe properties of these triangles and determine...

Young mathematicians view a video on solving quadratic equations by factoring. They use this skill to complete a worksheet of practice problems — a great way to gauge understanding!

Compare heating and cooling rates of different land forms. A lab activity has groups collect data on the rate of heating and cooling of soil, grass, saltwater, fresh water, and sand. An analysis of the rates shows how the different land...

You've probably heard of solar-powered cars, but what about wind-powered cars? Scholars build cars that can travel at least six feet. They can only use their breath to move the car—so, obviously, a sail might be a good feature for the...

Go on a moon mining expedition from the safety of your classroom with this space exploration simulation. Using simple models of the moon's surface prepared ahead of time by the teacher, young scientists are challenged with locating and...

Assist your class with correctly calculating the values for force, work, and power as they determine the amount various activities require. They gather data and participate in a group discussion to compare results upon conclusion of the...

Ron Toomer, a famous roller coaster designer, suffered from motion sickness. Pupils design their own roller coasters, learning about potential and kinetic energy in the process. Labs focus on the importance of drop height, energy...

How do oceanographers make maps under water? Junior explorers discover the technologies and processes involved in creating bathymetric maps in part three of a five-part series designed for fifth- and sixth-grade pupils. The lesson...

Construct a three-dimensional optical illusion when your class is exploring vision and how the eye and brain work together. Three concave corners are mounted inside of a black box, but as a light is shined upon them, they appear to be...

A wind turbine is essentially just a giant pinwheel, right? Individuals first create pinwheels from paper, pins, and pencils. In groups, they model a wind farm along a coast and then test out their designs using an electric fan.

Beginning with a brief history of our 26th president, Theodore Roosevelt, then followed by a discussion of his interest in nature, young scientists take to the outdoors to locate and observe local plants and insects....

High school physical scientists collide with motion. They work in pairs to design a paper car that will protect a raw egg during a head-on collision. Measurements of distance traveled, time of run, vehicle specs, and photo gate flags are...

Third graders use rulers to measure their shoe size in inches and centimeters. They then enter the class shoe measurements into an excel data base and graph the results of both to make the comparison.

Students explore the concept of boomerangs. In this boomerang instructional activity, students throw homemade boomerangs at different angles to record maximum distance and if it returned or not. Students collect their boomerang data then...
