Structure & Properties of Matter
Density and Buoyancy

Density and Buoyancy

Why do objects like wood float in water? Does it depend on size? Create a custom object to explore the effects of mass and volume on density! This interactive tool by PhET works on Mac & PC.

The Scale of the Universe 2

This creative learning tool is called The Scale of the Universe. When you get to the site just click the “Start” button to enter this mind boggling tool that will help your students gain perspective on their world and the worlds that they cannot see. This wonderful tool was created my Cary and Mike Huang.

Boyle's Law Graph

This simple and elegant learning tool is called Boyle’s Law. Just press your space bar and drag the plunger to see the relationship between volume and pressure. The interactive creates a data table automatically and students can choose to test air, hydrogen, helium, or oxygen. This fun interactive was created by Thomas Greenbowe at Iowa State University. Flash is required.


Just click the element you want to start with and then click one that will bond with it, the name of this “learning tool” is called Bonding. This textured and elegant demonstration is brought to us by the Department of Chemistry at Iowa State University.

Gas Properties

The name of this learning tool is called Gas Properties. This is a Java applet, just click RUN NOW to start. Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, change gravity, and more. Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other. This tool is brought to us by The PhET Project and made possible by the Kavli Operating Institute.

WebElements Periodic Table of the Elements

Billed as the first periodic table on the World Wide Web, this “learning tool” is called WebElements. has selected the WebElements web site as a winner of the 2002 Sci/Tech Web Awards. It is constantly being updated with awesome information about 118 elements!

States of Matter: Basics

States of Matter: Basics is a great simulation from the amazing people at PhET. Click on the link to see an interactive that will run on any device. The “For Teachers” section has documents that other teachers have shared for you to use with your students. Great sim and site. This runs on all devices. It is HTML5.

  • Each atom has a charged substructure consisting of a nucleus, which is made of protons and neutrons, surrounded by electrons. (HS-PS1-1)
  • The periodic table orders elements horizontally by the number of protons in the atom’s nucleus and places those with similar chemical properties in columns. The repeating patterns of this table reflect patterns of outer electron states. (HS-PS1-1)

About NGSS

Next Generation Science Standards is a multi-state effort to create new education standards that are “rich in content and practice, arranged in a coherent manner across disciplines and grades to provide all students an internationally benchmarked science education.”


Our team from Temple University has developed this resource for all K-12 students and teachers of science. These vetted learning tools align to the NGSS. Find one we should include? Just fill out the form.
