Students explore the five senses. In this health lesson, students read the book Brave Little Monster and identify the five senses from the book. Students draw an illustration from the book as a follow-up activity.

In this solubility worksheet, students answer eighteen questions including reading a graph to indicate solubility of three different compounds at particular temperatures, calculating percent of solutes in a solution, determining molarity...

In this density learning exercise, students calculate the density of objects given their mass and volume. They are given a table with the density of a variety of substances and given the mass or volume and must find the unknown.

Explore carbon and bonding with this worksheet. First, class members read a short excerpt about carbon and its characteristics. In response to the reading, they draw an electron dot diagram of carbon as well as diagrams of compounds...

At the top of the page are a reading passage and colorful diagram that depicts the tug-of-war that occurs between bonding molecules due to electronegativity. High school chemists fill in a chart with electronegativity values, the...

Introduce environmental science or engineering explorers to different forms of sampling. They read an article about "Robo-lobsters," lobsters being studied to help design robots that can used to sniff out pollution in ocean waters. The...

In this calculations worksheet, students find significant figures in numbers, they determine densities of substances and objects, they convert from one metric unit to another and they determine the appropriate unit of measurement for...

For this gases worksheet, students answer six questions related to the kinetic molecular theory of gases. They summarize the kinetic theory and they draw diagrams to illustrate different components of the theory.

Students understand the importance of maintaining a healthy weight and good health.  In this health lesson students read text then create their own pamphlet on the cardiovascular system, weight gain, treatments and health risks. 

In this calculations review worksheet, learners convert from one metric unit to another, they identify significant figures in numbers, they find density of substances, and they solve problems using dimensional analysis.
