Boiling down any division problem to a one-digit divisor problem sure makes estimation easy. The lesson shows how to estimate division problems by using place value understanding and basic arithmetic facts to simplify the division. Some...

Place the data in a box. Pupils experiment with placing dividers within a data set and discover a need for a systematic method to group the data. The 14th lesson in a series of 22 outlines the procedure for making a box plot based...

The truth is always best. Individuals continue to find values that make equations true in the 26th installment of the 36-part module. The only difference is that they now call them solutions to those equations.

Students investigate the effects of atmospheric pressure.

Students feel the changes in the amounts of greenhouse gases in the global atmosphere. They learn that the amounts of greenhouse gases in the global atmosphere are clearly changing. Some evidence of these changes includes levels of...

Students study coastal erosion and deposition by waves and sea-level rise in a particular area.

A great year-round activity that shows young mathematicians how the math skills they are learning are actually used in the real world. This exercise also helps learners begin to distinguish the difference between weather and climate. As...

Using different types of water, earth science explorers set out to prove the ocean's ability to absorb greenhouse gases. They heat, shake, and freeze the water samples to examine the gas content. This lesson is useful in a unit on...

High school scientists research and illustrate changes in the local environment and consider relationships among agriculture, industry, economy, natural events, and social interactions. They construct a timeline to discover if there are...

Students observe the local environment in relation to sea level variations and examine many clues that indicate sea level change.

Are we getting hotter? Let’s look at a sample locality where historical records exist and see what we can find out. Here is an activity that has young environmentalists plotting the average winter temperature in England from 900 to 1900....

In collaborative groups, mini-meteorologists investigate the conditions that must be present for clouds to form: cooling air, water vapor, and condensation nuclei. In addition to procedures, a chart for observations and some follow-up...

Young scientists investigate the effects of heating a beaker of ice water by dropping dye into the water and observing how the color circulates.

Students demonstrate the concept of outgassing and explain the origins of the Earth's atmosphere. They perform a simple experiment using glass jars, two antacid tablets, and some water. This experiment does a good job of demonstrating...

Young scientists show how carbon dioxide in the air affects plant growth. This math and science activity provides a good platform for learners to combine scientific knowledge with mathematical representation of data. A simple, yet...

When asked to list everyday objects that require energy, most people list technology that use batteries or electricity. Through hands-on exploration, young scientists discover energy is much more than just circuitry. They play with...

Where do directors and set designers get their ideas so that the set they build creates the mood and atmosphere the director wants for a production? From the script! Introduce theater high schoolers to the script analysis techniques used...

The second lesson in a unit on set design focuses on the importance of historical and stylistic research. Working in teams created in the previous session, groups consider what resources they will use as they consider design concepts for...

Bring on the coffee—it's dissertation time! As a handout on dissertations explains, over 50 percent of PhD candidates never finish their dissertations. The handout, part of a larger series on specific writing styles, helps motivate...

Scholars determine how two quantities vary with respect to each other. They complete a fill-in-the-blank activity by stating whether the entities vary directly, inversely, or jointly, create equations that match different variations, and...

Twelfth graders analyze and research physical and cultural changes to the city of St. John. Viewing photographs in a virtual exhibit, 12th graders draw conclusions about the culture and societal norms in St. John through the years. ...

Ninth graders create a scavenger hunt with clues related to a building they have researched. Working in small groups, they use the internet and traditional resources to find information pertaining to a historical building. Students use...

Sixth graders write an invitation letter to potential immigrants to St. John, New Brunswick, Canada. Using internet research, 6th graders gather information from a virtual museum exhibit highlighting the positive reasons to move to St....

Students practice photo manipulation and combination in order to create new images. Using composite photos, students mix them together to produce new photographs. They conceal stitch lines to create realistic forgeries of composite images..
