Just how big is Earth's moon? With a hands-on simulation, scholars use Play-Doh to model the sizes of the planets Earth, Mars, Jupiter, and their moons. They make predictions as a class, work together to make their models, and discuss...

How much plastic do manufacturers use to create water bottles each year? The class explores the number of water bottles used throughout the years to determine how many consumers will use in the future. Class members compare different...

Environmental science classes read articles about two different scientific studies. One is about the effects of contraceptive chemicals on fertility, and the other is about how a pesticide may be reducing bone density in exposed...

Take your class of youngsters on a prehistoric adventure with this four-lesson series on dinosaurs. Accompanying the Meet the Dinosaurs books by Don Lessem, these lessons engage children in writing their own dinosaur books,...

Three simple activities kick off a unit investigation of density. Your physical scientists make observations on the volume and mass of wood, water, and rocks, and make comparisons. Though this is written for grades three through eight,...

Our final proposal for the cost of the bridge requested is ... In the last segment in a series of 10, pairs work together to develop a proposal for a city bridge design. The class completes a cost comparison between concrete and steel to...

Data distributions can be compared in terms of center, variability, and shape. Two exploratory challenges present data in two different displays to compare. The displays of histograms and box plots require different comparisons based...

Not only do future engineers learn the difference between accuracy and precision, they also get some hands-on experience using different measuring tools. 

Acid-base indicators are an essential part of any chemistry classroom. Individuals explore the color-changing feature of the important indicators in a vibrant hands-on activity. Using serial dilution, learners create solutions ranging...

Class members explore the carbon cycle in the final installment of the 10-part Discover Your Changing World series. They play a simulation game where they walk through the steps carbon takes as it cycles through the different layers...

Complete teacher narrative and presentation slides for teaching about Earth's water make up the bulk of this lesson. Embedded within the slide show, you will find videos about the water cycle, keeping track of the limited supply of fresh...

Light a fire in your pupils! Scholars conduct a flame test and observe the emission spectra of several different salts in an enlightening hands-on investigation. They use their observations to make comparisons and conclusions about the...

Municipal government takes on many roles, not just the ones we are used to hearing about such as Parks and Recreation. Scholars delve into the topic to get a grasp on how the government system functions. They participate in readings,...

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...

Elementary life science explorers compare and contrast aquatic and terrestrial plants (elodea and soybeans) in a Venn diagram. Some background information is provided to support direct instruction, and general instructions are provided...

Tornadoes, blizzards, and hurricanes, oh my! In this lesson, meteorology majors compare stories of historical storms written by two or more different sources. As a result, they understand how the media portrays such catastrophes and...

Investigators construct a makeshift balance and compare equal volumes of wax and water. They do the same for clay and water. Then they discover whether the wax and clay will float or sink in water. Ultimately this is a comparison of...

Explore the concept of density within states of matter—gases, liquids, and solids—through a group experiment in which young scientists test objects' texture, color, weight, size, and ability to sink or float.    

What is the relationship between two variables? Groups work together to gather data on arm spans and height. Using the interactive, learners plot the bivariate data, labeling the axes and the graph. The resource allows scholars to create...
