Do flexible circuits change dimensions during fabrication? Groups use GeoGebra software to measure the length of pictures of flexible nano-circuits. To determine if the circuits change dimensions, future engineers use Microsoft...

Free-body diagrams display all forces acting on an object, helping scientists represent Newton's Laws of Motion. Scholars read a short description of motion and view the free-body diagram to begin the installment of a larger series on...

Scholars quantitatively apply their knowledge relating impulse, force, and time in the collision of objects. Three progressive levels challenge pupils with different ways of analyzing these problems. They identify multiple collision...

Learners characterize a physical change as something that changes to a different size, but retains its basic substance. They measure volumes using milliliters, and perform an experiment that proves that gases expand when hot and contract...

Students investigate the linear dimension change of heated plastic film and relate the results to processing and service use of the materials. They calculate percent change in dimension as related to anisotropy and molecular reorientation.

Students research about the function of MPA's. In this marine science lesson, students explore how humans influence changes near these areas. They explore different MPA's in the Great Lakes region.

Never underestimate potential—electric or your own. Scholars apply a color scheme based on the changes in electric potential as part of a series on electric circuits. They consider splitting wires, light bulb placement, and voltage as...

Young scholars examine the constant changing of the Earth's atmosphere. After labeling the layers of the Earth, they identify various processes inside the Earth that can cause gases to be emitted. Using the internet, they research how...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Physics class has its ups and downs ... especially when it involves energy concepts! Scholars analyze information to determine changes in kinetic and potential energy using an interactive resource. Realistic scenarios make connecting...

Aspiring astronomers study stars. They compare stars and explain the relationship between radius, mass, and diameter. By creating a star simulation, they discover how a binary star system's orbit can cause changes in the observed...

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...

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...

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...

Scholars connect statistical analysis with flexible electric circuits. They first learn about flexible circuits and their applications through a PowerPoint presentation and then consider how the fabrication process for these circuits...

Students measure various dimensions of a male and a female dolls body and scale them proportionally to average human measurements. They calculate the appropriate scale factor (magnitude) to enlarge their doll and apply that scale factor...

Three activities make up a solar system lesson that features the sun, its light, and the shadows it produces. Scholars step outside to discover the changes shadows make at different times of day, take part in a demonstration of...

Does the size of a sample change the physical properties of that substance? It turns out it can! Young scientists combine physics and chemistry to synthesize CdSe quantum dots and record their color properties. Learners should...

What can your class tell about a wave just by looking at it? Using a simulation, physics pupils work through a series of case studies to determine the effects of speed, frequency, and density on waves. Part of a larger playlist on waves...

What happens to the momentum of an object when it strikes another object? Scholars roll a marble down a ramp so it collides with another marble. By measuring the speed of each marble before and after the collision, pupils answer this...

Sometimes it's okay to rock the boat! Science scholars manipulate wave properties using a fun interactive. Part of a larger playlist that dives into waves and sound, the lesson helps users work their way from apprentice to wizard by...

How are charge, distance, and force related in electrostatics? Science scholars ponder the outcomes of changing variables using an interactive resource from the Static Electricity series. Individuals practice using Coulomb's Law as they...

Horizontal and vertical speeds change as projectiles move through space. As part of a series on vectors and projectiles, scholars create vector diagrams to compare these speeds at various locations. They they determine the values for...

It's all about density! Here's a dense workbook for young scientists; they solve (and show work for) 29 density word problems, including a problem where they solve for the density of Godzilla. They complete labs analyzing metal...
