Observations of Properties of Matter

Four activities immerse beginning chemists into the world of elements. They examine the periodic table, use cobalt hydroxide to learn about chemical formulae and valence electrons. Also, they name binary compounds and examine the...

In this metric units and properties learning exercise, students determine the proper metric unit given a variety of measurements for specific items. They also identify chemical and physical properties and chemical and physical changes.

This template is made up of cards for 18 common elements. The chemical symbol is provided, along with space to write in the numbers of protons, neutrons, and electrons, draw Bohr diagrams and Lewis structures, and more!

In this physical and chemical change learning exercise, students solve 13 clues in a crossword puzzle focusing on rates of chemical reactions and changes in the state of matter.

Students are able to observe chemcial and physical changes while producing a brilliant formation of foam. They are able to experience the use of an indicator in the reaction. Students record information based on their observations.

This PowerPoint is a gem! Seventy-eight slides present an entire introduction to matter in bullet-point fashion. Viewers learn about everything from mass and inertia to phase changes and gas laws! The only glitch is that the links to...

Beginning Boyles and curious Curies can safely experiment with the virtual mixing of elements using this entertaining application. 

Poor Sam! His graham crackers have undergone a physical change, so he can't make his s'mores! Mia explains that their molecules haven't changed, therefore they are still graham crackers. The two teens then discuss clues that would...

Does matter really matter? Properties of matter are discussed by Sam and RJ: mass, volume, and density. They differentiate between mass and weight. They explain how to measure these properties. Make sure to teach your class about other...

How can something we can't see be so powerful? Gas molecules make an impact! This video explains their properties: 1. Gas particles always move in a straight line. 2. They are too small to occupy any volume individually. 3. When gas...
