Pupils often wonder how we know the distance to various stars. Starting with a thought experiment and progressing to a physical experiment, they determine the brightness and distance to various stars. The evaluation requires...

An educational lesson allows young chemists to test the solubility of different types of salt at various temperatures. Groups create a graph using data from unsaturated, saturated, and supersaturated solutions.

Young scientists study light reflection and refraction as they determine the critical angle, the rainbow angle, and color separation in rainbows. Teams record the data they collect in a shared spreadsheet and discuss results with the class.

What is a prism? A place for light waves that commit minor refractions! The thorough resource includes three hands-on investigations covering light reflection and refraction; mirrors, lenses, and images; and optical systems. Subject...

Young scientists create a simulation of Hubble's law. Introducing the Big Bang Theory using balloons and a simple lab worksheet, scholars complete a data table and perform analysis.

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

What do you have in common with a fruit fly? About 60 percent of your DNA. The resource, divided into two units, is intended for grades four to eight and another for high schoolers. Both units include eight lessons covering the...

Physics is phun in this lesson. Young physicists use a lightbox to test how and where light is refracted and reflected as it travels through transparent materials. Angles of incidence and refraction, sine of both angles, and the...

I think I lost an electron. Are you sure? Yes, I'm positive! Starting with a hands-on demonstration and problem solving activity, young scientists define vocabulary related to circuitry and currents. Then they build their own circuits...

Dracula isn't the only one who needs blood to survive. The eight-part unit includes seven lessons, five demonstrations, seven labs, and a project to organize a blood drive. Class members learn about the parts of...

What is the real cost of electricity? The real cost is not just the price you pay, but the environmental and economic costs as well. Scholars build, use, and judge the effectiveness of a turbine. They also investigate the...

Who's your Daddy ... and Mommy for that matter? Given a first-generation group of gummy bear offspring, young scientists must determine which bears are their parents. An activity worksheet covers the differences in genotypes and...

Have you ever wanted to play with a giant pendulum? An experiment allows small groups to do just that. They gather data and make observations as they complete the included worksheet. The instructional activity lays out each instruction...

So you built a magnetometer, now what? High school scientists use their magnetometer made in a previous lesson to map the union of magnetic fields of dipole magnets. They experiment with different alignments and draw conclusions about...

High school scientists build their own magnetometer and use it to map the field surrounding a bar magnet. Excellent background resources is included, as well as a diagram of how to build the magnetometer.

No GPS allowed! High school scientists continue to explore magnetic fields with a hands-on activity. After mapping the ambient magnetic field in the classroom and completing data analysis, they write about the similarities and...
