This activity will take complex molecules and polyatomic ions the students have learned and construct them out of marshmallows and redhots. This develops understanding in VESPR structures and hybrid molecules.

This is a lesson about determining planetary composition. Learners will use a reflectometer to determine which minerals are present (from a set of knowns) in a sample of Mars soil simulant. Requires the use of ALTA II spectrometers (which may be borrowed from the Lunar and Planetary Institute or purchased online) and Mars soil simulant. The activity is part of Project Spectra, a science and engineering program for middle-high school students, focusing on how light is used to explore the Solar System.

This activity is a series of game-like lessons that assist the student in developing the logic skills needed to read mass spectrometer output and formulate the identity of an unknown molecule. As students endeavor to identify the unknown they must apply fundamental chemistry knowledge including formula mass, isotopes, periodic table, relative abundance, interpreting graphs, organic chemistry, ionization, bonding rules, and structural formulas. Based on an activity presented by Olaf Runquist, Professor, Hamline University.

In the first part of this video, we derive the law of mass action from one example of a picture of molecular collisions. For this course, we use the "law of mass action" to refer to an idea that chemical reaction kinetic rates can be expressed using products of the abundances of reactants raised to exponents. Studying cooperativity and Hill functions in the second part of the video allows us to investigate a simple example of bistability in the third video segment.

A realistic mass and spring laboratory. Hang masses from springs and adjust the spring stiffness and damping. You can even slow time. Transport the lab to different planets. A chart shows the kinetic, potential, and thermal energy for each spring.

Two astronauts aboard the International Space Station (ISS) describe mass and weight and the differences between the two in this video from NASA’s Teaching From Space initiative.

Short Description:
Most chemistry textbooks introduce students to the mathematics of chemistry, such as scientific notation, significant digits, and unit conversions. However, many students need to review and practice other mathematical topics, such as powers of ten, metric prefixes and conversions, determining when conversions are exact or measured, solving equations for a variable, and canceling units. This book contains tutorials on these topics, as well as links to more practice problems. It is suitable for any beginning introductory or general chemistry student.

This provides a mathematical method of balancing chemical equations as an alternative to the conventional method (by inspection)

Students will use scientific notation and metric conversions to complete the following labs and activities.

This is an indoor lab that uses a boat simulation to demonstrate the concepts of mass, volume and density, and their relationship to displacement. It is a problem solving activity that encourages student creativity resulting in a variety of valid solutions.

You and a friend are hiking the Appalachian Trail when a storm comes through. You stop to eat, but find that all available firewood is too wet to start a fire. From your Chem 106 class, you remember that heat is given off by some chemical reactions; if you could mix two solutions together to produce an exothermic reaction, you might be able to cook the food you brought along for the hike. Luckily, being the dedicated chemist that you are, you never go anywhere without taking along a couple chemical solutions called X and Y just for times like this. The Virtual Lab contains solutions of compounds X and Y of various concentrations.

This activity is an inside lab experiment where the students combine primary colored liquids correctly to create a rainbow.

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.

Marie Hartford's class of 5th grade scientists learn about the importance of water quality and its benefits to wildlife and the environment. Within the narrow confines of pH necessary for their tank of red-legged frogs, students use a combination of pond and tap water to keep the tank healthy, using their collected data to make the decision on the proportion between the two.

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.
