Don't waste all that carbon dioxide. Scholars first produce carbon dioxide by mixing baking soda and vinegar. They measure the masses of the reactants and products to verify the law of conservation of mass. As a culminating activity,...

How much do you actually weigh? It all depends on gravity. Scholars explore why gravity varies in different locations and how these variations affect weight.

Chemistry was a bit of a late bloomer in terms of scientific progress! Discover the Age of Enlightenment and its effects on how researchers viewed matter with an engaging video. The narrator highlights the work of Antoine Lavoisier and...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine differences in...

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....

Many people study for years to understand even a subsection of chemistry, yet an informative video attempts to cover all of chemistry in 12 minutes. It starts with atoms and elements and moves through bonding, reactions, energy, and...

Thinking back to the last time you taught a lesson on chemical changes ... was there no reaction? Check out an explosive video to put some spark back in your instruction! The narrator of the video guides you through the expectations, as...

It's time we get to the heart of the matter! Explore standard PS1A in an informative video. The narrator guides viewers through the basic ideas of the structure and properties of matter. then discusses helpful strategies for...

Add a little balance to the school year! Learners develop a strategy for balancing chemical equations. The video lesson explains the process and demonstrates it with an example.

Prove the Law of Conservation of Mass through a lab investigation. A well-designed lesson asks groups to combine materials and monitor indicators for chemical reactions. Measuring the mass of the reactants and products allows individuals...

Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for comparison.

How do chemists reach 100% efficiency in a reaction? And, why is efficiency so important? Young chemists answer this question and learn how, by using catalysts that can maximize yield and reduce waste. 

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation. The...

Show class members how to balance equations, keeping in mind the conservation of mass, with a video demonstration that provides a few sample problems and solutions. 

New things are created all the time while others disappear, does the Law of Conservation of Mass mean your drone might be made out of dinosaurs? The 16th video in a series of 29 begins with a timeline of scientific discoveries related to...

Theory versus reality strikes again — only this time, scholars figure how close they come to each other. Video explains how to use the numbers for theoretical yield and actual yield to determine the percentage yield of various...

First equations had numbers, then chemical equations had letters, then they added in numeric subscripts, now what is going on with the alphabetic subscripts? The sixth video in a 29-part series explains how states of matter symbols are...

When a candle burns down, what happens to the mass that appears to be shrinking? Lesson begins with a demonstration of the chemical reaction of a candle burning. Then scholars use atom models to observe conservation of mass concretely. 

Imagine if scientists today were killed for their thoughts, ideas, and beliefs. And yet, Antoine Lavoisier was beheaded for just those things in 1794. Learn about this fascinating aspect of science along with the contributions of...

Once I told a chemistry joke, but there was no reaction. Get young chemists involved in changes and reactions with a presentation that begins with physical and chemical changes and chemical reactions. It moves on to chemical equations...

An informative video segment describes how to balance chemical equations. It ensures pupils will obey the laws of conservation of mass and shares tips to assist young chemists who may need additional help to ensure a more simplistic way...

Using the 5E method for teaching about kinetic energy, potential energy, and conservation of energy, this two-week unit with many videos and possible extensions is sure to keep pupils engaged as they are learning.

Get your blocks out! It's time to start building and learning about mass! Enthusiastic chemists get in-depth information about the conservation of mass and the way it applies to chemical changes.
