Bacteria Take Over and Down
Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

Boiling Point of Polar and Non-Polar Substances
Go to extremes to illustrate boiling point! Junior chemists explore the effects of heating and cooling on polar and non-polar substances. The interactive allows users to raise and lower the temperature, set specific temperatures, and...
Concord Consortium
Boiling Point
Is it getting hot in here? Observe boiling from inside a beaker in an engaging interactive. Chemistry scholars heat and cool polar and non-polar solids and observe how molecules react to temperature changes. Your class' misconceptions...
Concord Consortium
Temperature and Reaction Rate
Does increasing temperature increase the rate of a chemical reaction? Junior chemists examine the effects of temperature on reaction rate using an engaging interactive. Pupils select the temperature of the reaction vessel, then observe...
Concord Consortium
Making and Breaking Bonds: The Effect of Temperature
Time to turn the heat up on your next bonding lesson! Young chemists explore temperature, kinetic energy, and bonding through an interesting interactive. The controls allow individuals to vary the temperature, as well as pause progress...
Concord Consortium
Catalysis
Get ready to kick things up a notch! Young scientists explore the effects of catalysts using a fun interactive. Learners start the reaction without using a catalyst, then add one over time to examine its effects on reaction rate.
Concord Consortium
Concentration and Reaction Rate
Does concentration affect the rate of a chemical reaction? Science scholars observe and control a chemical reaction in an interactive simulation. The resource allows pupils to add atoms to the reaction vessel and monitor the reaction's...

Electrochemistry
In an electrolytic cell, electrical energy is converted into chemical energy, the exact opposite of a battery! Lesson 15 in a series of 36 explores electrochemistry. Participants begin by reading and discussing oxidation/reduction...
Teach Engineering
Concentrate This! Sugar or Salt...
Heat up your lessons on boiling points. The resource provides a three-part activity: first, groups find the boiling point of solutions; second, they create boiling point curves for salt and sugar solutions; and third, they mix a solution...

Adsorption and Catalysis
Adsorption, not absorption, is when atoms stick to the surface of an object, like water sticking to a grain of sand. An informative lesson delves into adsorption, teaching physical and chemisorption and the factors that affect them....
National Institute of Open Schooling
Solid State
Crystal comes from a Greek word meaning ice. Activity eight in a series of 36 has class members analyzing amorphous and crystalline solids and further classifying them based on their forces. They then explore solids, learning about unit...

Chemical Kinetics
Not all chemical reactions happen at the same rate because some, like explosions, occur quickly and some, like rusting, occur over time. Here, learners explore chemical reactions and their rates in the 16th lesson of 36. Through readings...
National Institute of Open Schooling
Ionic Equilibrium
Scientific studies show the older we get, the more acidic we become. The activity extensively teaches high schoolers about acids and bases. By the end of the 14th installment of 36, they can define and explain three concepts of...

Soap, Slime, and Creative Chromatography
Do you think chromatography paper suffers from separation anxiety? Young chemists make soap, slime, silly putty, and experiment with chromatography in this lesson. The material includes clear instructions for each experiment along with...
Steinhardt Apps
Kinetic Molecular Theory
Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...
Virginia Department of Education
Heat Transfer and Heat Capacity
It's time to increase the heat! Young chemists demonstrate heat transfer and heat capacity in an activity-packed lab, showing the transitions between solid, liquid, and gaseous phases of materials. Individuals plot data as the changes...
