Charles' Law Worksheet
Although it was published in the year 2000, this chemistry assignment is ideal for practicing the application of Charles' law. There are seven real-world problems to solve, and plenty of space provided for doing so. Add this to your...
Science 4 Inquiry
The Monster Mash
Young scientists create monsters by applying their knowledge of transcription and translation. They randomly find the DNA, assign it a codon, and build monsters piece by piece.
Curated OER
Stalactites And Stalagmites
Learners conduct a scientific investigation about the formation of stalactites and stalagmites. They conduct an experiment to reproduce them in the lab environment. Students make observations over a period of time in order to see the...
Beyond Benign
Green"er" Precipitation Reaction
All sodium carbonate may not have the same amount of carbonate, but it should have the same percent. Learners write and balance an equation to predict the chemical reaction between sodium carbonate and zinc acetate. Through the lab...

Eruptions and Volcano Types
The Mammoth Lakes area regularly releases warnings to hikers and skiers to be careful because melting snow releases trapped gases from volcanic vents. The 17th activity in the 20-part series opens with a demonstration of carbon dioxide...
Curated OER
Acid Rain
Learners perform experiments to determine how different acids cause acid rain. They measure the pH of the water to calculate the water's acidity. They discover how acid rain dissolves rock materials.
Curated OER
Rusting and the Scientific Method
Students observe the oil can scene with the tin man from a clip from "The Wizard of Oz" and answer the question, "What can we learn about rust from this scene?". They take 2 tubes and 2 nails, adding 1 salt packet to 2 ml of distilled...
Curated OER
A Cloud In The Hand
Students investigate the scientific concept of forming clouds. The use simple materials to simulate the formation. This creates a powerful visual for students to make cognitive connections. They make observations and record them in a lab...

A Catalyst and the Rate of Reaction
More than 90 percent of chemical products are made using a catalyst. Lesson demonstrates the way a catalyst changes the rate of reaction without altering the chemical reaction. A catalyst doesn't appear as a reactant or a product, yet it...
Texas Instruments
Endothermic and Exothermic Processes
Students investigate temperature using the TI. In this chemistry lesson, students analyze the change in temperature, as chemicals are dissolved in water. They analyze data collected using the CBL 2.
