Round and round they go ... where they stop, only scholars will know. By writing systems of equations, classes determine the number of cars a roundabout can handle given specific constraints. Systems use up to six variables and become...

After removing the shell from a raw egg, cell biologists soak the egg in either a hypotonic, hypertonic, or isotonic corn syrup solution. They calculate the percent change in mass and compare it to the strength of the solution in a...

Students demonstrate a sequence of events through the creation of an animated flowchart. Students research the internet and select parts involved in assembling a car. They animate the model and the parts. Students create a flow chart...

Seventh graders view "Volcano" by National Geographic Video. They experiment with baking soda and study lava flow. They describe volcano and earthquake patterns. They analyze weather and climate changes and how they relate to the natural...

An ecosystem is really just the flow of energy through many different living organisms. A study of Rudyard Kipling's The Jungle Book leads to an environmental science activity in which learners study how various factors can affect...

Is everything really connected? Take your class on a walk outside, where they will make observations and write them down on a worksheet. Once they are back in the classroom, learners will work to determine if and how things like birds,...

No more beating the pavement to find a virtual model of the human heart. See one in continual real-time motion, and layer it to highlight electrical impulses, blood flow, and valve activity. 

Scholars first complete an assessment task on writing linear equations to model and solve a problem on a running race. They then take part in a card matching activity where they match equations and graphs of lines to diagrams of fluid...

Swimming pools are no fun without water. For a pool in the shape of a trapezoidal prism, scholars first calculate the amount of water needed to fill the pool. They use experimental data on water flow to determine whether to haul water...

Explore methods for solving linear systems with your classes and introduce learners to using matrices as a viable method. Scholars are able to recognize situations where matrices are the efficient method of solving. Application...

When we think of ocean exploration, many of us have visions of sunken pirate ships full of treasure or mysterious creatures of the deep. What really motivates deep-sea investigation? The first in a series of diverse six-part lessons...

Middle schoolers explore how a whale's countercurrent flow of blood is an example of a heat exchange system and conduction. Excellent worksheet provided.

Students examine current flow and describe ways in which it may effect food of reef building corals.  In this coral lesson students identify two environmental factors that may affect the morphology.

Students investigate finite mathematics using a flow chart. In this algebra lesson, students investigate logic and strategies using flowcharts. Students compete against each other using different approaches to playing the game.

Here is another in the interesting series of lessons that use the special State Quarters as a learning tool. This one uses the North Dakota State Quarter. During this lesson, your class learns about the different patterns of erosion, and...

Providing clean water to a town is quite a feat... is your class up for the challenge? After a short reading about water towers, groups work together to design a working water delivery system. The water flow must be adjustable (able to...

Every moment, the systems in your body are working together to keep you breathing, standing, and thinking. Elementary schoolers explore the human body and its systems with an impressive, 15-page lesson plan that should leave your...

Beyond the phases of the moon, this comprehensive lesson plan covers geologic history and geology. Amateur astronauts examine photos of the lunar landscape, experiment with the creation of craters, and delve into information about the...

Which requires more water--a bath or a shower? Given some specific criteria, learners attempt to answer the question. A video shows how long it takes to fill a gallon container using a faucet and a shower head. Using that information and...

Glaciologists in your class make models of glaciers to simulate how they move down a valley, and then they use it to test any aspect of glacier movement. Not only is this a vivid visual of how these monsters of ice flow, but it is also...

How does electricity work? Budding scientists explore the concepts of electrical currents and open and closed circuits with class discussion and a hands-on activity using a battery to turn on a light bulb. Learners also make predictions...

Don't be shocked when your class has a blast making their own batteries! Science scholars examine a dry cell battery, then design and construct a wet cell battery. The activity guides them through the parts of a battery, the variables...

Learners design a battery, identify and label the anode, cathode, electron flow, ion flow, oxidation & reduction reactions, chemicals used including the location of each;and distinguish between anode materials with regard to energy...

Examine the power of technology while modeling with polynomial functions. Using the website wolfram alpha, learners develop a polynomial function to model the shape of a riverbed. Ultimately, they determine the flow rate through the river.
