Classification of Matter

Does the change in energy of matter lead to a change in mass? Upcoming chemists compare the mass of equal-volume, but different-temperature liquids and materials both before and after a chemical reaction has occurred. In another...

Engage the class like never before as pupils learn to differentiate between multiple physical and chemical changes by conducting a list of small experiments, most often with household materials. They make observations and discuss the...

This is a great worksheet with an infographic to assist your students in categorizing matter into mixtures and non-mixtures. Information is given about the metric system of measurement. Your young students match 13 terms with their...

Thirty-seven slides thoroughly shed light upon the four classes of matter: elements, compounds, mixtures, and solutions. Also covered are chemical symbols, molecules, and chemical equations. The colors and fonts chosen for the...

You are living, occupy space, and have mass; therefore, you matter! The video discusses matter including both substances and compounds. Then it details elements, mixtures, and phases of matter before concluding with a couple of...

Don't get mixed up about the differences between elements, mixtures, and compounds! Part one of a six-part series discussing these important classifications of substances illustrates simple tests one can perform to determine a material's...

Take an energetic ride through the phase changes of a water molecule in a compact activity. Young scientists learn about the phases of matter and discover the role of thermal energy in governing phase changes while watching a short...

Do not pass this resource by! Everything you need to teach the property of density,and the separation of mixtures is here: an educational video, several classroom handouts, and a laboratory exercise. The video is engaging, though a...

[Free Registration/Login may be required to access all resource tools.] In this online tutorial students will define a mixture and understand why mixtures are different than pure substances. They will classify mixtures as homogeneous or...

Time to show what they know! Module five in a 14-part series about solids, liquids, and gases redirects to an interactive quiz. Learners test their skills on topics such as states of matter, phase changes, and Brownian Motion. With...
