A good companion to your class on the American Revolution, this slideshow provides a short series of maps that detail major campaigns and battles. Though the information on the slides is not sufficient for an entire lecture, the images...

The two images in this presentation - a graphic depicting American's financial structure and debt, and a map showing American posts that were still held by the British after 1783 - could be helpful for a class lecture on the emerging...

Add these slides into your lecture about the Jeffersonian Era in American history. Slides detail the results of the Presidential Election of 1800, four Barbary states of North Africa (Morocco, Algeria, Tunisia, and Tripoli) and the...

Beneficial for a discussion on the Mormon trek to Utah (Deseret), the solitary image in this slideshow details their journey from Nauvoo to modern day Salt Lake City. The slide would be a good visual aid for a lecture about the...

Though too short to be an adequate presentation, the solitary map in these slides would be a good visual aid to a lecture about Southern secession before and during the Civil War. The color coded states on the map make a good timeline...

Presented here is a series of maps showing demographics, expansions routes, and economic hot spots of the late 1700's. No text is available to reference, but it is likely that this slide show is meant to accompany a Houghton Mifflin high...

With a map on the military reconstruction in the post-Civil War South, and an interesting graphic comparing the size of Alaska to the continental United States, this presentation could be a good (albeit short) supplement to a class...

Many various pieces of information about the Wilson administration adorn these slides. For instance, a map with 1912 election results, a chart detailing the organization of holding companies, and another map outlining U.S. presence in...

America's status as a world power came relatively quickly after the American Revolution - as did the expansion of its borders. The slides in this brief presentation detail the period from 1890 to 1899, in which a series of maps detail...

Very briefly detailing the election of Franklin D. Roosevelt, this slideshow consists of two maps, the first of which shows the election results in 1940, and the second of which indicates the main flow of Lend-Lease Aid. An instructor...

A glimpse of the political and economic contexts of the 1970's, this series of slides includes two graphs (median family income and Consumer Price Index) and a map that details the results of the 1972 Nixon-McGovern Presidential...

Fifth graders participate in online astronomy activities with hundreds of fun explorations into astronomy as a classroom tool for learning how to theorize, experiment, and analyze data.

Students examine why air pressure is hard to notice. They observe the height of a liquid in a tube over time and lift a table with balloons.

Students explore the historical problem of pumping water out of mines.

Students study passive causal agents, such as air pressure, in a system. They conceptualize air pressure as passive and omnidirectional, with molecules that make up the air bouncing off surfaces with which they have contact in all...

Students explore how temperature is related to air pressure and introduces students to Charles' Law through the lens of relational causality.

Young scholars realize that density exists. They develop a mental model of density-to realize that something is going on that they cannot see to account for differences between materials.

Students explore simple electrical circuits. Students experiment, using different configurations, to determine what is necessary to compeete a circuit. Students observe similarities between arrangements that work and differences in...

Pupils analyze light bulbs and their design. They create filaments and build a circuit for testing the filaments. Through experimentation, students discover how filament wire works. They explore the role of protons, electrons, and...

Students investigate Ohm's Law. Through experimentation, students observe Ohm's law. Using the voltage and resistance, students calculate with Ohm's law. Students collaborate in other activities to apply Ohm's Law to series and...

Students define density as a relationship. Through experimentation, they explore the association between the mass and volume of pure substances. Students create a data plot and analyze the patterns between mass and volume. Students...

Students consider the causes of density at a microscopic level. They then discover that one cause of density has to do with how many protons and neutrons the material contains.

Students discuss the each of the following objects/substances in terms of what contributes to their density: 1) a piece of copper; 2) a piece of bread; 3) steam in the air. They evaluate the causes in the various densities of substances.

Students explore volume and pressure. Through an activity, students discover what happens in situations when volume is increased but no additional air is able to enter the enclosed space. Students create models and explain their...
