Oh Nuts! - Calories Count

Why do you weigh more in space? Each individual in your class explores this question and others as they determine the mass and weight of different objects using two types of scales. They perform conversions and discuss their results,...

Oh nuts! Do macadamias or almonds produce more thermal energy? Energy enthusiasts find out with this experiment. The objective is to demonstrate to your class how the chemical energy contained in foods can be converted into useable...

Engineer an autonomous underwater vehicle (AUV) to study concepts of physics. Using household materials, collaborative groups design and build an AUV and then test Newton's Laws of Motion as they apply them in underwater environments...

Facilitate learning by using small objects to teach the principles of atomic mass in your science class. Pupils determine the average mass of varying beans as they perform a series of competitive experiments. They gather data and...

By focusing on "Candium", pupils can work through this guide to learn more about different isotopes.  The teacher will supply M&M's, Skittles and Reeses Pieces to provide data about mass and abundance.

The term stoichiometry derives from the Greek words stoicheion meaning element and metron meaning measure. The second Socratica video in a two-part series within a larger chemistry playlist introduces more complex stoichiometry problems....

Molar mass, gram molecular mass, and gram formula mass essentially mean the same thing. The brief video, part of the Socratica "Chemistry Lessons" playlist, explains how to solve these problems. It walks through the required tools, the...

Students conduct an experiment to compare the total mass of products to the mass of reactants. In this conservation of mass lesson plan, students devise an experiment to show that matter is neither created or destroyed in a chemical...

Students investigate mass-mass relationships using potassium carbonate and hydrochloric acid. In this mass-mass relationship lesson plan, students measure a certain amount of potassium carbonate and determine how much hydrochloric acid...

Students will determine what an unknown substance is by finding mass, volume, displacement, and density of an object. Students will also create a report which will require them to read a graph, interpret data, calculate averages, and...
