This app for iPad devices is a fully interactive atomistic simulation that shows the motions of atoms as they attract, repel, and collide with one another. With the tap or swipe of a finger, students can add, delete, or highlight molecules, as well as increase/decrease temperature, pressure, or volume and explore the states of matter. An associated simulation, Salts, allows students to manipulate atoms and ions to join to form crystals.

This demonstration involves properties of carbon dioxide and hydrogen. A video is included in addition to the written instructions. It touches on a number of areas of chemistry: density of gases, solubility of gases, sublimation and combustion. Each of these areas could be explored in more detail, depending on the level of the group.

Students will be able to explain, on the molecular level, how a gas dissolves in water. They will also be able to explain why the gas comes out of solution faster in warm water than in cold water.

Students will place isopropyl alcohol, mineral oil and corn syrup in water to see if any of these liquids dissolve in water. Students will extend their understanding and definition of "dissolving" and see that certain, but not all liquids can dissolve in water.

This supplemental resource is to be used during the lesson "Chemistry 201: Physical and Chemical Properties and Changes." In this lab activity, students observe various changes in matter, massing the chemicals before and after the changes.

This supplemental resource is to be used during the lesson "Chemistry 201: Physical and Chemical Properties and Changes." The data sheet will be used by students to record their data and observations during the associated lab activity. In this lab activity, students observe various changes in matter, massing the chemicals before and after the changes.

In this lesson, students watch a brief episode of Science Matters. Students are tasked with taking notes, completing several assignments, and recording lab data. This lesson focuses on physical and chemical properties and changes.

This supplemental resource is to be used to record notes during the video used in the lesson "Chemistry 201: Physical and Chemical Properties and Changes."

This supplemental resource is to be used during the lesson "Chemistry 201: Physical and Chemical Properties and Changes." In this activity, students decide whether listed properties and changes are physical or chemical.

This is a culminating activity to be used after completion of a Thermochemistry unit, or later in the curriculum as review or evidence of concept retention.  Students will create and label a heating curve, and explain what is happening on a molecular level using Livescribe Echo pens.

This lesson looks at the compositions and structure of diamonds and basic mineral structures formed by the bonds in the crystal structures created by nature. The students have an extensive hands-on lab experience with crystal growth from two very different processes, all recorded on video for later analysis. They also use the internet for a short introductory lesson to crystal systems and use the Nature Video “Diamonds” to tie their knowledge back to real life.

This resource is a part of the Diamonds Are Forever-Most of the Time lesson plan. This resource provides step by step ways for teachers to implement the lesson.

This online resource defines and describes the phase changes of water. There is a brief assessment at the end of the reading.

Students will explore the boiling points and freezing points of water and alcohol, including the differences between salt water and fresh water. Students will also examine water's ability to store heat.

In this activity, students will work in small groups to take vocabulary words and concepts about solutions and phase changes and break them down to the level of lower elementary age children. This will be done by writing and illustrating a children's book. Students will learn by teaching the subject and working with peers. Students are expected to come away with a solid understanding of solutions and phase changes that they were largely responsible in building themselves.

Students will observe a solubility test between salt and sugar. They will then be presented with 4 known crystals and an unknown. Based on the solubility demonstration, the class will design a solubility test to discover the identity of the unknown.

Students will be able to explain, on the molecular level, how the polar characteristic of water and sugar interact so that water dissolves sugar.

This resource is an animation that accompanies the lesson, "Why Does Water Dissolve Sugar?"
