Can you disprove the law of conservation of mass? Pupils observe the teacher weigh each part of a reaction. Then, the teacher weighs the result of the reaction and everyone sees that the products do not equal the reactants. Then they...

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...

Three memorable activities build on each other to give physics masters a firm grasp of Newton's Second Law. Pupils play with a lab cart on a flat surface and on an incline to confirm that force is equal to mass times acceleration. In the...

Working under specific constraints and with designated criteria, groups work together to create a product using an assembly line process. In addition, they work through the entire engineering design process with an excellent graphic to...

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...

The third lesson in a series of 11 begins by using thermal decomposition of potassium chlorate to determine the mass percent of oxygen. Then a second activity allows scholars to demonstrate that the resulting residue is from a...

What happens to the momentum of an object when it strikes another object? Scholars roll a marble down a ramp so it collides with another marble. By measuring the speed of each marble before and after the collision, pupils answer this...

What do budding scientists know about moles and reactions? Using an attention-grabbing lab experiment, young scholars collect data to apply the law of conservation of mass to predict the mass of gaseous products. They examine several...

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,...

Bubble, bubble, boil and trouble! What causes common substances like baking soda and vinegar to react the way they do? Welcome your junior chemists to the wonders of acid-base chemistry using a comprehensive and fun...

Long before modern labor unions, guilds worked to ensure that workers had a fair wage. But, in medieval Europe, they also cooperated with the government. Using a simulation and primary source analysis, young scholars become hatters in...

Here is a tasty challenge, especially for middle school engineers: design a container that meets mass and volume criteria, and will safely transport a tortilla or potato chip through the mail without damaging it! Mostly, this is a crisp...

The set for a play combines design elements (style, line, shape, mass, measure, position, color, and texture) and principles of composition (unity, harmony, contrast, variation, balance, proportion, and emphasis) to create a particular...

Is there a correlation between a country's wealth and the extent of its ecological footprint? What exactly constitutes an ecological footprint, and how does one country stack up against the rest? This is a unique lesson to incorporate...

Oncology presents multiple opportunities for research and the collaboration of many different types of scientists. Scholars divide into groups and research the history of mass spectrometry, polarity/non-polarity,...

Show young chemists what a chemical reaction looks like with two parts of a hands-on experiment. First, learners conduct a wet lab where they observe the reactants (baking soda and calcium chloride, with phenolsulfonphthalein)...

One of the most recognizable commercial melodies was written in 1977, and led to gastronomical relief around the world. Scholars use Alka Seltzer tablets to measure reactants and calculate the chemical equation for the reaction of NaHCO3...

The radical reactions of polymers seems abstract to many pupils, but this instructional activity turns them into a fun building game. Scholars use dice and building pieces to build polymers. Then, they determine the theoretical and...

In search of an organic lab that employs real-life techniques and analysis methods? Groups carry out the nitration of methyl benzoate, then attempt to determine the number and location of the nitro groups added to the benzene ring....

What are fibersheds and what what do they have to do with environmental protections? A photo essay and audio recordings about Mimi Luebbermann, and her sheep, cause consumers to reflect on how their clothing choices can support local...

Every child's dream: stuffing as much candy into a bag as possible. Doing this, though, requires a nice sturdy bag. Scholars design the sturdiest bag they can and test the limits of those bag using a sweet treat!

North is to factory as South is to plantation—the perfect analogy for the economy that set up the Civil War! The first lesson in a series of five helps teach beginners why the economy creates a driving force for conflict. Analysis of...

Use this cross-curricular history lesson to work on your students' informational writing skills. After listening to songs and stories related to Sultana, they engage in a several activities to boost their understanding of slavery and...

Teaching is a balancing act! Keep things on an even keel with a comprehensive equilibrium lesson plan. The resource covers reversible and irreversible reactions, Le Chatelier's Principle, and the industrial applications of equilibrium...
