High schoolers complete an activity and make "provable estimates."  In this dimensional analysis activity students use dimensional analysis and complete an activity. 

Learners solve problems using dimensional analysis. In this chemistry lesson, students choose a problem and present it in class. The rest of the class will evaluate the solved problem on the board.

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. 

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...

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...

Students find the percent composition of sugar in the gum. In this chemistry activity, students calculate percent error from the experiment. They use dimensional analysis to convert between units.

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. 

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...

Human fingerprint patterns are the result of layers of skin growing at different paces, thus causing the layers to pull on each other forming ridges. Here, groups of learners see how patterns and fingerprints assist scientists in a...

Students perform computer simulations on air dispersion. In this chemistry instructional activity, students calculate energy transfer based on specific heat and temperature change. They explain the causes of smog.

Students conduct a flame test on different substances. In this chemistry lesson, students predict the element present based on the color emitted during the flame test. They explain how different elements produce different colors.

Students study the basic structure of the atom. In this chemistry lesson, students explain how colors relate to energy that electrons emit. They calculate energy of the emitted photons.

Students compare and contrast the English and Metric system. In this chemistry lesson, students demonstrate how to convert English to metric and vise versa. They solve problems following the rules of significant figures.

Students analyze data taken from proteomic experiments. In this biology lesson, students explain the importance of bioinformatics tools in the study of proteins. They evaluate scientific results using math and computer software.

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

Avoiding lab safety rules will not give you super powers. The lesson 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 mixture and trying to...

Hate to vacuum, but enjoy using a vacuum pump? Explore a activity 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 plan begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed...

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...

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...

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...

Students engage in a laboratory lesson in order to increase understanding of the impact of phosphates at the chemical and ecological levels. The lab exercise is completed with the goal of getting them to predict the outcomes and future...

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 lesson in a series of six.
