MolView
Interactive
With this resource, students can use the tools on the left side of the screen to draw a 2D organic molecule, then by clicking the "2D to 3D button", students can directly observe the corresponding 3D ball and stick model. The program is geared toward line drawing notation of organic molecules, however, by clicking the "C-H" button at the top of the screen, students can toggle the skeletal formula notation. Additional "Tools" include an "Information Card" which provides the chemical name, formula, molecular weight, percent composition, and in some cases, even a description of its real-world application.

SOLUTIONS, ACIDS, AND BASES 

H.C.5A.1  

Sugar and Salt Solutions  
Interactive simulation 
What happens when sugar and salt are added to water? Pour in sugar, shake in salt, and evaporate water to see the effects on concentration and conductivity. Zoom in to see how different sugar and salt compounds dissolve. Zoom in again to explore the role of water.  

H.C.5A.2  

H.C.5A.3   

Concentration
Interactive simulation 
Watch your solution change color as you mix chemicals with water. Then check molarity with the concentration meter. What are all the ways you can change the concentration of your solution? Switch solutes to compare different chemicals and find out how concentrated you can go before you hit saturation! 

H.C.5A.4  

pH Scale 
Interactive simulation 
Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH.  

Gizmos Feel the Heat
