Mike and Kellie, a team of electrical engineers, demonstrate how to to design a contraption that accurately drops a marble onto a target. The materials needed and general instructions are provided on the website or via a downloadable...

Simplify the Common Core Math Standards for sixth graders with this comprehensive list of key vocabulary. Complemented by a series of word cards that support the meaning of each term with images and examples, this resource provides...

Alone, or as part of the intended unit on chemical reactions, this activity allows learners to experience an exothermic reaction. Here, learners add calcium chloride to a baking soda solution and watch the temperature rise! They will...

Now that learners have been exposed to chemical changes, they learn that some take in heat and therefore, decrease in temperature. The same reaction that they have been investigating between baking soda and vinegar is revisited,...

Classroom and studio music instructors will find this packet of 10 transparencies of major value. Images of treble and bass clefs, notes and rests, note values, time signatures, and music language are included. Nothing minor about this...

Recycling is the focus in the sixth of a nine-lesson series devoted to forest ecosystems. Class members read an article about the responsible use of natural resources and ways to reduce land fill.

In an online engaging and animated game, pupils role play as lawyers charged with protecting rights found in amendments to the United States Constitution. As they choose appropriate amendments to match the right that has...

How does heat move from one item to another, even when the items are in different states of matter? Pupils experiment with adding washers to hot water and adding hot washers to room temperature water to observe the heat transfer. 

If the Supreme Court is so supreme, why do all cases not just start there? High schoolers learn why every case does not start at the Supreme Court as well as the importance of hierarchy in the US judicial system in the 11th installment...

Pupils apply their knowledge of refraction to four different sets of challenges. Each of the first three focus on one variable's impact on the direction of bending. The fourth combines variables for greater challenge.

Magnifying glasses and cameras often use converging lenses, but how do they alter an image? Pupils discover a lens, axis, and object arrow before identifying four characteristics of the resulting image. They label the location,...

Scholars work through three different activities applying their knowledge of total internal reflection (TIR). First, they simply identify which diagrams create TIR and which don't. Next, they match different types of boundary behaviors...

Scholars relate each of the colors in the spectrum, except indigo, by comparing their frequencies, wavelengths, and energy levels. Then, they compare each section of the electromagnetic spectrum when considering the same three variables.

Light intensity varies by the strength of the light bulb as well as the distance to the light bulb. Pupils apply these concepts independently at first. They must solve for the light intensity as either the distance or the wattage of the...

The dress color debate of 2015 taught the importance of understanding how we see light. Scholars view a shirt under two different colored lights and then must predict what color the shirt will appear under a third light. They apply color...

Objects contain pigments that selectively absorb a wavelength of light, and our eyes only observe a very small range of these wavelengths. Scholars apply these two facts to three different activities. They identify the pigment in an...

Filters provide amusing changes to images in applications other than just Instagram! High school pupils apply their knowledge of colored filters to three different interactive sets of puzzles. They identify light colors that pass through...

Reflection seems simple to understand, but without a complete understanding, pupils struggle with ray diagrams, specular versus diffuse reflection, total internal reflection, and image formation. An engaging interactive provides three...

While only briefly mentioned in most Physics books, plane mirrors and their applications offer the basics necessary for future studies. While working through an interactive, pupils demonstrate knowledge of both reflection and its forms....

We see curved mirrors every day in spoons, rear-view mirrors, stores as a safety measure, make-up mirrors, and in novelty stores. Scholars explore the changes to an image based on the curve of the mirror, the location of the image, and...

How have Russian politics affected countries on a global stage? The discussion of the Russian Revolution and World War I begins with an analysis of primary resource letters. Learners finish with a project where they create a timeline of...

Test six various reagents for their ability to conduct electricity. Cooperating chemists research whether each is ionic or covalent and discover the relationship between bonding and conductivity. This laboratory exercise would be an...

Excellent diagrams, labels and summaries make this resource be valuable to your students throughout the topic of circulation. All types of circulation vessels are explained, their structure and function is detailed, and the overall...

A slideshow that covers the all-important details related to basic human circulation. The reasoning for exchange of material methods is presented and then labeled diagrams of the main human transfer systems are shown, along with...
