What constitutes a good soap bubble? In the second installment of a nine-part series, scholars apply their understanding of surface tension to soap bubbles. They experiment to determine the best solutions to use for the...

Students comprehend the meaning of "pixel." They recognize patterns using pixels. Students observe how land use can be determined from a pixel. They measure off a 30 x 30-meter area to show the size of the surface area of one pixel....

For this surface water worksheet, 6th graders will read 12 statements related to surface water and the movement of rivers over the land. In each statement, there is a bold-faced word that the students will unscramble and place into a...

Did you know some retailers use curved mirrors in their fitting rooms to make customers look thinner? Pupils view themselves in convex and concave mirrors to understand the difference. The resource includes big ideas for multiple age...

Students create a model of centrifugal compressor wheel following step-by-step instructions. In this technology instructional activity, students use SolidWorks to create curved surfaces. They give practical applications of a centrifugal...

The need for a respiratory system in humans versus being reliant on gas exchange structures is demonstrated. There are many details about the advantages and disadvantages of each mechanism.  Students are able to learn about the...

Explore structures within the realm of gas exchange in terrestrial and aquatic life.  The excellent, labelled diagrams and clear descriptions help your students view the different structures and adaptations that have...

In this reflection worksheet, students will review the law of reflection and label a diagram with its angle of incidence and angle of reflection. Then students will compare different mirror surfaces as convex or concave. This worksheet...

Heat up your lessons on boiling points. The resource provides a three-part activity: first, groups find the boiling point of solutions; second, they create boiling point curves for salt and sugar solutions; and third, they mix a solution...

Using flexible mirror-like paper, physical scientists experiment with images produced by curving it and looking into its reflective surface. They find that concave mirrors cause reflected light waves to cross and actually flip the image...

Seventh graders experiment with white light, plane mirrors, and curved mirrors in order to demonstrate the physical principles of living systems. In this physical principles lesson plan, 7th graders take 3 days to discover what happens...

For this surface water worksheet, students review water runoff, drainage basins, and river erosion. This worksheet has 7 multiple choice and 3 fill in the blank questions.

Students investigate topology. In this Applied Science instructional activity students explore higher, more abstract mathematics using tangles. Students make topologically related shapes.

Demonstrate how the spherical shape of the Earth contributes to unequal heating of its surface and results in varying climates at different latitudes. This would be an illuminating addition to your meteorology lessons, especially when...

Begin a full lesson on climate change by demonstrating how carbon dioxide gas contributes to increased temperatures. Be aware that pressure inside the antacid-containing bottle in Activity 2 may cause the lid to fly off; keep viewers at...

Eighth graders conduct a "Length of Day Symposium." They complete a variety of activities and explorations regarding the earth's rotation, its revolution around the sun and the cyclic changes in climate and energy distribution on the...

This is not revolutionary, but it is informative. Earth science viewers in grades 7-12 get carried away with wave and wind erosion. They view diagrams of how waves impact ocean shorelines. They see examples of the different types of sand...

Students learn to use a tide table in plotting tidal curves and create a tide calendar by plotting a month-long tidal curve on an ordinary pictorial calendar.

In this Hubble Space Telescope instructional activity, students are given a photograph of the radiator recovered after being in space on the Hubble Space Telescope since 1993. Students solve 6 problems about the impacts that left craters...

Third graders discuss how Aristotle concluded that the Earth was round. As a class, they review theories about the Earth's shape and describe how life on Earth would be different if it were flat. Individually, they make a moon book in...

Students discover the basic principles of aerodynamics, including the roles and identity of natural forces involved. They examine how the force of gravity is overcome by the curved shape of an airplane wing and air pressure.

Students explore how different textures provide varying amounts of friction to objects moving across them. They build a tool to measure the amount of friction between a note card and various surfaces by measuring the distance that a...

Students explore the characteristics of a pure sound wave produced by a tuning fork. They use sine waves to find a curve to fit the sound wave data produced by the tuning fork. A CBL and microphone is required for this activity.

Eighth graders describe how light behaves when it strikes a surface. In this physics activity, 8th graders investigate how the different types of mirrors reflect light. They work with their chosen group on a task they selected.
