Students apply the principles of chemistry to investigate the concept of how a hydrogen powered car works. They study the electrochemical reactions that provide the energy source. Students also record observations in the functioning of a...

Fourth graders expand their knowledge about how the physical properties of a substances can be changed. They are given multiple opportunities, using first-hand experiences and familiar objects in different contexts, to identify...

Students explore the concept of environmental stewardship. In this science activity, students discover how scientists assess damages to the environment following oil spills. Students conduct a simulation of a public meeting in order to...

In this chemistry review worksheet, students answer and solve 95 questions about chemical reactions, hydrocarbons, functional groups, moles, acids and bases and solutions.

Measuring fun is here! In this week's adventure, children will explore volume, capacity, and weight and learn new math vocabulary words as they practice measurement with real and virtual measuring tools. Each section of this weeklong...

A four-step tutorial shows students how to use a pipet in general chemistry lab to make "precise and accurate" volume measurements. View the full-length lesson via streaming video [9:46] or in segments.

In this lab, students will measure and combine colored liquids to receive the expected results. The intended outcome would be to take primary colored liquids, measure them and combine them to create a "rainbow" colored set of water in...

In this first part of a two-part lab activity, students use triple balance beams and graduated cylinders to take measurements and calculate the densities of several common, irregularly shaped objects with the purpose to resolve confusion...

This performance task tests students' ability to measure length, volume and temperature accurately in a lab setting.

In this week's Afterschool Adventure, Appetite for Fractions, children will explore fractions as they help create, divvy up, and serve a variety of real and virtual snacks.

Tutorial shows proper procedure for handling a buret and using this piece of laboratory equipment to measure liquid volume. View accompanying video full-length [18:00] or in segments.
