Do you separate your trail mix before eating it? Then you've been separating mixtures your whole life! Scholars model a contaminated soil sample using trail mix and estimate the percentage of each component. They consider how to clean up...

In this universal gravitation worksheet, students answer thirteen questions using the equation for universal gravitation, and force equals mass times acceleration.

Young scholars experiment with objects of different densities. In this density lesson, students examine same-sized objects with different weights, then look at a teacher explanation of density. Young scholars make wave bottles and a...

Fourth graders examine the principles and uses of inclined planes, screws, and wedges while they determine examples of simple machines that are use in everyday life. They separate different kinds of fruit into pieces to determine the...

Students draw on their previous studies of American history and culture as they analyze primary sources from Jackie Robinson and Other Baseball Highlights, 1860s - 1960s in American Memory. A close reading of two documents relating to...

Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

Militaries throughout history have used topography information to plan strategies, yet many pupils today don't understand it. Scholars use Legos and a contour gauge to understand how to construct and visualize topographic profiles. This...

Practice electric vocabulary using multiple methods. Learners begin by watching a video that explains vocabulary related to electric currents. They match vocabulary cards to practice and then create an electric circuit. Using the...

What common chemical includes safety warnings for being harmful if swallowed or inhaled, causes serious eye damage, and needs to be cleaned up immediately if spilled on the floor? Surprisingly, the dangerous chemical turns out to be...

Students explore the concepts and engineering principles used in a canal lock system and apply those concepts to navigate a boat through a working model of a canal lock waterway.

Learners are provided with drawings of planet surfaces in order to investigate different types of planetary terrain. They make observations for each planet and discuss the characteristics observed. The lesson plan includes background...

Students explore the possibility of being on Mars and being able to identify the Earth.  In this space lesson students complete a set of calculations to see if this is possible. 

In this finding mass in the cosmos instructional activity, students use the equations for the force of gravity, the centrifugal force pushing a planet outwards and the speed of a planet to solve 2 problems. They find the mass of primary...

After a short introduction, chemistry aces get right into drawing electron dot diagrams for covalent bonds. There are only three questions to answer, so this is not a comprehensive worksheet. It can be used when introducing your class to...

Students identify variables that affect the system, and specify which variables are independent and which are dependent.

High schoolers construct an interferometer using a simple telescope. In this physics lesson, students explain how light waves create the fringe patterns. They observe patterns made by different objects in the sky and compare them.

Students explore primary and secondary colors. In this lesson on light and color, students complete four different activities which include mixing colors, creating secondary colors from primary colors and observing the colors in a bubble.
