Demonstrate to your middle school science learners how chalk breaks down in a weak acid. Discuss what affects acidic rain might have on ecosystems. Lab groups then choose one of two questions: "How does acid precipitation affect an...

It has been decades since the discovery of DNA. Still, activities such building this DNA model allow blossoming scientists to better understand the components that form this overall structure. During this activity, they will also...

As physics masters view this presentation, they learn how nuclear power is used in submarines. They use Google Maps to plot a course through the ocean and calculate the time required for surfacing and traveling. They learn about fission,...

During this hands-on activity, young chemists build molecular models based on the Lewis dot structure before studying valence shell electron pair repulsion theory. 

Young astronomers learn about the Big Bang Theory and redshift through a hands-on activity in the last installment of a three-part series. Participants draw dots on balloons and then inflate them to model how galaxies moved farther apart...

Why do experiments require a control? Guide scholars through designing an experiment to see what they can do to evaporate water faster with a lesson that stresses the importance of controlling all variables. The second activity...

Does increasing the pressure between two moving plates provide a stabilizing force or create more destruction? The hands-on instructional activity encourages exploration of strike-split fault models. The sixth instructional activity...

To be or not to be — is the question really that simple? According to the classic quantum mechanical model ... well, maybe! Explore the nature of event prediction and probability in a short, animated video. Young physicists...

Physical science fans find out how supercooled water droplets in the clouds can become crystalline snowflakes. They learn about the categories of snowflakes (plates and columns) and the variables that determine their patterns...

Historically, scientists had to be creative to study subatomic structure. Scholars step into their minds to recreate the procedure Rutherford used to create his atomic model. Learners identify the creative efforts of early scientists...
