In this Illuminations lesson, students apply their knowledge of addition equations to investigate the equivalence of two numeric expressions using the "Pan Balance-Numbers" applet (cataloged separately). An instructional plan, questions for the students, assessment options, extensions, and teacher reflections are given for the lesson as well as links to the applet and a student activity sheet(word format).

This activity is an investigation where students explore the properties of color and light, using mixtures of common everyday materials.

After using the historical development of the Standard Model to develop introductory understanding, students link to OPAL and DELPHI data archives from CERN to identify and study the tracks from elementary particles.

This activity is used to introduce the different properties of states of matter, by testing an unknown substance with household materials to determine which state of matter most closely resembles the material. It also can invole data collection, reasoning, grph making, and presentation of findings.

Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the interaction potential to the forces between molecules.

This video segment from IdahoPTV's D4K explains and gives examples of the 4 states of matter: solid, liquid, gas, and plasma.

This activity is a lab investigation where students observe the four states of matter. At the end of the investigation students should be able to know that the differences among the physical states depend on the distance between the atoms or molecules and on the rate of movement of the atoms or molecules. And, that pressure and temperature control these two factors.

Students act as chemical engineers and use LEGO® MINDSTORMS® NXT robotics to record temperatures and learn about the three states of matter. Properties of matter can be measured in various ways, including volume, mass, density and temperature. Students measure the temperature of water in its solid state (ice) as it is melted and then evaporated.

Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the interaction potential to the forces between molecules.

Heat, cool and compress atoms and molecules and watch as they change between solid, liquid and gas phases.

Students will statistically analyze data gathered in reference to the Abraham Lincoln penny.

This course discusses the principles and methods of statistical mechanics. Topics covered include classical and quantum statistics, grand ensembles, fluctuations, molecular distribution functions, other concepts in equilibrium statistical mechanics, and topics in thermodynamics and statistical mechanics of irreversible processes.

The classic Stern-Gerlach Experiment shows that atoms have a property called spin. Spin is a kind of intrinsic angular momentum, which has no classical counterpart. When the z-component of the spin is measured, one always gets one of two values: spin up or spin down.

This activity is a lecture where students learn the basic concept behind stoichiometry, mole ratios.

Explore stretching just a single strand of DNA using optical tweezers or fluid flow. Experiment with the forces involved and measure the relationship between the stretched DNA length and the force required to keep it stretched. Is DNA more like a rope or like a spring?

Short demonstration on scientific notation by asking students to place numbers on a number line using string and notecards.

This lab and demonstration activity involves students conducting chemical reaction experiments to determine the chemical reaction type and writing balanced equations.

This activity is a lab where students gather data using glass pipettes to understand the concept of precision and data analysis.

This lab is an activity designed to demonstrate to students the importance of the proper use of lab equipment. Also to demonstrate how math can be used as a tool for analysis of data.

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.
