This activity is an inquiry lesson where students learn how to accurately read a thermometer and then set up an investigation to compare the temperatures of different materials or locations.

What can you do with chemistry skills? A lot of things, it turns out! Learn about the diversity of careers available to people interested in chemistry.

Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.

This video segment adapted from Discovering Women profiles Fermilab physicist and Harvard professor Melissa Franklin.

Monitor the temperature of a melting ice cube and use temperature probes to electronically plot the data on graphs. Investigate what temperature the ice is as it melts in addition to monitoring the temperature of liquid the ice is submerged in.

Metric Conversion at a Glance is an easy way to teach students how to convert one metric measurement into another without the use of fractions. It works for one, two and three dimensions length, area and volume.

Dr. Michael Smith (1932-2000) won the Nobel Prize for Chemistry in 1993 for his work in mutagenesis, which involved altering DNA sequences. This is his autobiography.

Learn about an important physics experiment that uses an invention that manipulates light in this interactive activity adapted from NASA.

This group learning activity involves students in an engaging review of concepts of microbiology. The review is set up as a power point presentation in the style of the "Jeopardy" gameshow where students groups compete against each other to answer review questions.

In this video from DragonflyTV, Tiana and Sammy measure, record, and analyze the results of a drop box test to find out how everyday items behave in microgravity.

Students use one hand to gesture crystallographic axes and the other hand to represent planes designated by Miller Indices.

In this geology activity, students investigate the physical property of mineral cleavage by physically trying to break down a block of halite and describing the results. This lab addresses many misunderstandings non-majors have about the physical properties of minerals and includes a brief write up of their conclusions.

This activity is a lab investigation in which students make mass/volume measurements of several samples of the same mineral to determine the mineral's density. Students graph their data and make the connection between their qualitative understanding of what density is and the mathematical/graphical representation of density.

Again- this is activity that will set the stage for enriching the understanding of the nature of molecular motion and the affect of temperature on its rate as the students allow crystals to diffuse toward each other in a petri dish and form a precipitate.

This activity is a laboratory extension where students test and collect data on two kitchen materials in the categories of solubility, saturation, chemical reaction and weights. Thus, giving students opportunity to reinforce skills already learned.

This activity is a guided practice and scaffolding activity in which the students learn how to configure electrons of elements and determine the number of valence electrons.

Provides a definition for both mole and molar mass and gives a step-by-step example problem to work through that shows how to compute molar mass. Also has a a molar mass calculator in which you can practice problems on.

This activity investigates the molar conversions used in a single replacement reaction between copper and iron.

Learn to identify different molecular shapes, to understand the interactions that create these shapes, and how to predict a molecule's shape given certain information about it. Explore these concepts using three-dimensional computer models and answer a series of questions to reinforce your understanding.

In this activity, students interact with 12 models to observe emergent phenomena as molecules assemble themselves. Investigate the factors that are important to self-assembly, including shape and polarity. Try to assemble a monolayer by "pushing" the molecules to the substrate (it's not easy!). Rotate complex molecules to view their structure. Finally, create your own nanostructures by selecting molecules, adding charges to them, and observing the results of self-assembly.
