Do you think chromatography paper suffers from separation anxiety? Young chemists make soap, slime, silly putty, and experiment with chromatography in this lesson. The material includes clear instructions for each experiment along with...

How does water pollution affect the environment? Provide your class with the resources to answer this question as they learn about eutrophication and ecosystem changes. Over two weeks, they simulate the effects of pollution on the...

This handout, produced in the UK, contains a chart of cations and anions. It explains how ionic compounds are formed and named. This concise and attractive handout can be helpful as a reference for your chemistry apprentices.

Accomplished chemistry learners set up a calorimeter and measured the energy released by various alcohols: methanol, ethanol, and either propanol or butanol. Lab masters will first need to design their tables for recording data. Consider...

Here is a laboratory exercise in which chemistry masters conduct an oxidation reaction to change ethanol into ethanal. They compare the original alcohol to the resulting aldehyde by forming a precipitate. This activity is aimed at...

Third graders examine plate movements and boundaries with a lab that demonstrates how volcanoes and earthquakes are formed. It presents different types of stresses an object can withstand through a hands-on...

For this thermal decomposition of calcium carbonate learning exercise, learners perform three experiments on calcium carbonate, make observations, and write the equations for each reaction. Students explain in detail what happened at...

In this halogen chemistry learning exercise, students complete a practical to gain experience observing inorganic halogens and their salts. They observe changes in each chemical reaction and write the chemical equation for each experiment.

In this compound worksheet, students complete a graphic organizer by combining positive and negative ions appropriately and writing down the resulting compound.

In this chemical reactions learning exercise, students practice writing chemical formulas, word equations, and symbol equations. They also identify the types of reactions. This learning exercise has seven problems to solve.

For this atmosphere worksheet, students read a data table showing the percentages of carbon dioxide, oxygen, and nitrogen in the atmosphere over the last 4500 million years. They then create a graph comparing these gases over time and...

In this elements worksheet, students complete a graphic organizer by filling in the symbol and atomic number for the given elements. Students plot a graph of melting point against atomic number. Students write the electron arrangements...

Abracadabra! Provide your class with the tools to perform a chemical "magic show" as they predict the charges of various ions, determine ionic compound formulas, and make observations to determine when a chemical reaction between...

Scholars become rocket scientists as they take off on a journey exploring Newton's laws of motion. After learning the laws of motion, pupils design their own investigations using straw rockets. They highlight their literacy skills in a...

For this compounds activity, students identify molecules as compounds and provide a reason why they believe it is or is not a compound. Students write out chemical formulas. This activity has three problems to solve.

Rather than simply matching up the ionic charges on paper, this exercise gets chemists into the lab to determine the chemical formula for magnesium oxide! If a known amount of magnesium is used, an oxidation reaction results in this...

During this lab activity, chemists discover the reactivities of chlorine, bromine, and iodine as examples of the halogens. They use a displacement reaction as a test by adding other compounds and observing for a color change. The lab...

This publisher has put out some terrific laboratory activities for your aspiring chemists! This edition uses displacement reactions to develop a reactivity series for three halogens. Not only do they explore the reactivity of bromine,...

Chemistry stars experiment with metals to observe reactivity with salt solutions. They test magnesium, zinc, iron, and copper by immersing them into different solutions and observing for changes. A separate set of data tables is...

This is not a learning exercise per se but a reference sheet for your chemistry class. It lists cations and anions, their chemical symbols, and their net charges. Also included is a thorough explanation of combining these ions to form...

Your chemistry class set up six different redox reactions in the lab. Inquisitors methodically test each one and eventually order them according to oxidizing strength. This is a neat way to have the learners perform more than one...

No practice problems are given on this handout; it is a detailed list of concepts to know and tips for working related problems in chemistry. Give this to learners as a study guide, or use it early in your career as a chemistry...

For this formula for magnesium oxide worksheet, students perform an oxidation reaction between magnesium and the oxygen in the air to produce magnesium oxide. Using the known masses of the magnesium and the end product, students find the...

In this redox reaction learning exercise, high schoolers perform a redox titration to determine the number of iodide ions that react with each mole of iodate (V) ions in a solution. They calculate their answer using a given equation.
