Using simple materials, an informative lesson demonstrates the Law of Conservation of Matter and explains how to balance chemical equations. Young chemists perform experiments, analyze reactions, and balance chemical equations...

Newcomers to chemistry compare hydrogen peroxide to water, realizing that the difference of one oxygen atom significantly affects the chemical properties. Other pairs of compounds and their formulas are also examined. A few chemical...

Math and science come alive in this career-related lesson on sanitation. Along the way, learners explore bacterial growth rates using exponential notation and graphs. A link to a very brief, but vivid video shows just how quickly these...

What did one titration say to the other titration? We should meet at the end point! Young chemists perform four experiments: dilute solution, neutralization, titration, and figuring pH/pOH. 

The best part of learning about equilibrium is that nothing changes. Young chemists observe four demonstrations during this lesson plan: equilibrium in a saturated solution, equilibrium with an acid-base indicator, equilibrium with...

Nine action-packed organic chemistry exercises are contained in this mini-unit on carbon containing compounds. Examples include constructing models of alkanes, producing aromatic esters, and preparing pigments for paint and dyes....

In this chemistry worksheet, students examine the concepts of mole and molarity in order to apply in the laboratory setting. The sheet includes in depth background information.

Why did Mr. Ohm marry Mrs. Ohm? He couldn't resistor. An electrifying simulation allows scholars to control both voltage and resistance in order to see the current change. The formula is displayed and as you increase one variable, it...

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...

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...

Lost an electron? You should keep an ion them. Young chemists learn qualitative analysis in the second lesson of an 11-part chemistry series. After observing reactions of simple salts, the teacher provides pupils with unknown...

Sixth graders explore the concept of density as a relationship of an object's mass to its volume. Densities of a variety of objects are compared and used to identify an unknown object.

Young scholars simulate block and tackles to lift heavy objects. They lift cargo by hand with the whip and the two-fold purchase to simujlate what crew members do aboard ships. They measure the effort and distance pulled for a gun...

If your pupils think a catalyst is a list of their cats, then this might be the lesson for you! Young chemists study the effect of temperature, catalysts, concentration, and particle size on reaction rates during four different...

Eighth graders differentiate photosynthesis and respiration. In this biology lesson, 8th graders draw a diagram explaining these two processes. They answer a quiz after the lesson.

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. 

In this chemical reactions worksheet, students are given directions about three types of reactions and how to write balanced equations for each. They then are given ten practice problems to complete using the information given.

In this chemical reactions worksheet, students read about the 3 types of chemical equations and how to write balanced ionic equations. Students are given 5 equations to balance, write the type of reaction, write the total ionic equation,...

Students participate in a teacher-guided activity to teach about protein synthesis. Student roles include one person as the DNA molecule, another is a single stranded sequence of complementary mRNA.

For this NASA satellites worksheet, students read about the Magnetosphere Multi-Scale satellite constellation that NASA will launch in 2013. They solve 4 problems including finding the volume of the MMS constellation, finding how long it...

Twelfth graders read and interpret v-t graphs. After studying velocity and time, 12th graders read graphs to calculate the acceleration of a moving body and determine the distance and displacement of a body. Students explore the...

Students listen to Chapter I, Chapter II, Chapter III, and Chapter IV of "The Forgetful Pony". They observe different stages of development of mealworms. The student sequences pictures to show the life cycle and draws the developmental...

Second graders learn the proper way to take measurements, explore the properties of objects and expand their vocabulary.

Students use a DNA strand to identify the component parts. They discuss an RNA molecule, protein fragments, and nucleotides. They explore how the order of nucleotides determines the order of amino acids in proteins.
