MORE THERMOCHEMICAL CALCULATIONS (MIXED)

Which is worse — drought or flooding? Neither is helpful to the environment, and both are increasing due to climate change. The 16th lesson in a series of 21 covers the average precipitation trends for two different climates within the...

Currently, only 2.1% of global warming is felt on continents, while over 93% is felt in the oceans. The fourth instructional activity in the series of 21 on global warming is composed of three activities that build off one another. In...

Le Chatelier's interest in thermodynamics and building materials such as cement and plaster led to the Le Chatelier Principle in 1884. Activity 13 in a series of 36 extensively explores chemical equilibrium. Learners read about...

Substances with the same empirical and molecular formula must be differentiated by their structural formula. Part two in a series of 36 has pupils using chemical formulas to calculate how much of a compound is present in a given...

How can a robot measure the length of something when we don't know how far the camera is from the object? The lesson explains the concept of perspective and many others. Scholars apply this knowledge to judge the length of fish and the...

In this chemical equations worksheet, students write and balance chemical reactions. They complete 98 short answer and problem solving questions on molarity and chemical equations.

Viewers learn where the heat goes when phase changes take place with a presentation that explains the latent heat of phase changes, or, more specifically, the molar heat of fusion, solidification, vaporization, and condensation. The show...

The Earth is over 70% water and so are our bodies. What makes water so special? Learn about water and its properties as it relates to solutions, dilutions, electrolytes, and molarity.

I can get more water to stay on a penny than you can! Collaborative pairs determine the volume of liquids that can be contained on the surface of copper pennies and plastic coins. The pairs analyze their results using graphs and go on to...

Can a small change in laboratory procedures save energy? Scholars test three different methods for heating water in a science lab. Then, they calculate the energy efficiency for each and compare them to determine which uses the least...
