Quantity Analysis Teacher Resources

What is unit rate? How is a ratio converted to unit rate? Really, it's just about getting the denominator of a ratio to be 1. When the denominator is 1, the ratio is a unit rate. Check out this video as the instructor illustrates a few...

Here's a real-world word problem. It involves walking for a certain amount of time. There are some given values to use. So take the given values, set up the ratio and then convert that to a unit rate value. Now use this unit rate to get...

Equip your chemistry class with the tools to properly understand endothermic and exothermic reactions. Young chemists collect, analyze, and graph data to determine how the Law of Conservation of Matter is applied to chemical composition...

Searching for a relatively interesting way to demonstrate Charles' Law? Here is a lesson in which pupils heat air inside a flask and then cool the flask to quickly cool the air. They make observations about what occurs during the cooling...

Young scholars find the density of diet soda and regular soda. In this density lesson plan, students measure the mass of a graduated cylinder with 10 different volumes of each soda. They find the mass of the liquid alone and use the...

Grab your youngsters' attention by reading the poem, "Smart" by Shel Silverstein. The son in the poem was not smart in how he handled his money. Mathematics whizzes help him out by using ratio problems to re-calculate his money exchange....

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...

If you need a way to assess the concepts in your physical science class, use an extended set of worksheets as a midterm or final exam. It includes questions about density, physical and chemical matter, speed and velocity, weight and...

Litmus paper, why so blue? A chemistry lesson includes a pre-lab activity, practice calculating pH, an experiment measuring the pH in acids and bases, a titration demonstration, and a titration experiment. 

Avoiding lab safety rules will not give you super powers. The instructional activity opens with a demonstration of not following safety rules. Then, young chemists practice their lab safety while finding the mass of each item in a...

Hate to vacuum, but enjoy using a vacuum pump? Explore a lesson that starts with a demonstration of boiling water at various temperatures by using a vacuum pump. Then scholars design their own experiments to measure vapor pressure and...

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to boil water through...

What makes particles attract? Here, learners engage in multiple activities that fully describe colligative properties and allow the ability to critically assess the importance of these properties in daily life. Young chemists conduct...

What is a chemist's favorite plant? Stoichiome Tree! Scholars produce hydrogen gas by reacting magnesium with hydrochloric acid. Then they calculate the molar volume of the gas produced before answering assessment questions. 

What happens when you combine 6.022 times 10 to the 23 piles of dirt into one? You make a mountain out of a mole hill. Scholars use dehydration to obtain percent composition and then calculate the molarity of the original solution. 

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...

At some point, everyone has been under pressure—even Dalton! Explore Dalton's law of partial pressures with young chemists as they measure the volume of air extracted from a sample compared to its original volume. Class members perform...

Want my name and number? It's 6.0221415 times 10 to the 23rd, and my name is Avogadro. Providing nine different activities, experiments, and labs, this lesson keeps Avogadro relevant to your class all year long. 

Scale drawings are used to represent many things. Scales are used all the time on maps, and in architectural drawings. Watch this video as the instructor illustrates a simple drawing of a blueprint to represent the footage of an actual...

Develop the right station to solve rate word problems. The 18th lesson plan in a series of 29 starts by interpreting the aspects of rates with two different quantities. Pupils use the interpretation of rates to solve problems, and groups...

Young chemists create gold nanoparticles as they learn to measure accurately with the metric system. They create an advertisement for the application of nanotechnology to complete the first instructional activity in a series of six.

The fifth instructional activity in the six part series introduces units of energy including calories, Calories, and joules. Scholars determine the energy released when eating a snack and during activity.

Sixth graders convert customary linear measurements. They explore using ratios to convert from inches to feet, ounces to pounds, etc. In groups, 6th graders complete conversions. They explain to the class how to solve their problems.

Young scholars examine stoichiometry. In this chemical reaction and mole lesson, students complete an experiment based on readiness levels to explore that changes are quantified in chemical reactions.
