Are the people on the other side of the world standing upside down? Pupils discuss the relationship between movement and position words. The unit explores the concept of reference points through animation, modeling, photography, and...

Students complete four activities that are about meteorology. The first activity is for them to explore weather maps. The second activity is for students to discover high-pressure and low-pressure air. The third activity is for them to...

The first STEM lesson in a group of 10 explores composting. After discussing how to make a better tomorrow, classes are challenged to track garbage in their communities, visit a local waste management facility, and conduct a survey...

Get things moving with this elementary science unit on simple machines. Through a series of nine lessons including teacher demonstrations, hands-on activities, and science experiments, young scientists learn about forces, motion,...

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,...

Water, one of the basic needs of humans, is found in all three states of matter on Earth; no other planet—that we know of—possesses this quality. Here is a unit that allows learners to explore through experimentation what it...

Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.

Students will discuss the de Brogile Hypothesis and state the circumstances under which the wave nature of matter is observed. They will also calculate the wavelengths of matter waves.

In this exercise, students practice arithmetic word problems with mass. Students receive immediate feedback and have the opportunity to get hints, watch a tutorial video, and try questions repeatedly. CCSS.Math.Content.3.MD.A.2 Measure...

A comprehensive guide for learning all about mass with definitions, how to calculate mass, the difference between mass and weight, solved examples, and practice questions.
