Repeated motion is present everywhere in nature. Learn how to 'make waves' with your own movements using a motion detector to plot your position as a function of time, and try to duplicate wave patterns presented in the activity. Investigate the concept of distance versus time graphs and see how your own movement can be represented on a graph.

This activity is an extension activity following a unit study on mixtures and solution. Students will use variables to create a unique cola formula and present their findings.

This Chemistry experiment investigates physical changes, solutions, supersaturated solutions, and states of matter.

In this short demo/activity, a balloon with baking soda in it is stretched over the mouth of a flask or bottle containing vinegar. The balloon is tipped so that the baking soda falls into the vinegar, and the reaction creates carbon dioxide, which inflates the balloon. The activity is part of the children's book, The Air We Breathe.

In this video segment adapted from ZOOM, cast members make a seismometer and experiment with different ways to make it register movement.

Where the tropical ocean meets the sea, a peculiar kind of plant thrives in shallow, salty water. These mangrove plants are incredibly important for shoreline protection and baby fish habitats. In this video, Jonathan investigates life in mangroves by visiting both Caribbean and Pacific mangroves. Please see the accompanying study guide for educational objectives and discussion points.

This video adapted from NASA explains how a magnetometer determines magnetic fields around planets.

TED Studies, created in collaboration with Wiley, are curated video collections — supplemented by rich educational materials — for students, educators and self-guided learners. In The Deep Ocean, aquatic explorers take the TED stage to share what they've seen in the abyss of Earth's last frontier: the deep ocean, home to massive underwater mountains and valleys, giant smoking chimneys and an amazing array of animals.

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.
