Precipitation reactions are always interesting. How about one that forms a precipitate using a gas? Chemists of any age will enjoy this twist on a standard solubility lab. Partners observe the lack of interaction between sodium...

Some of kids' favorite toys are the products of science experiments. Scholars follow precise measurements to mix and create their own slime and Play-Doh. They observe the changing textures and the chemical reactions throughout the...

Show your class how to recycle during this simulation with polylactic acid. Pupils use a plastic cup, made of PLA, and convert it into a cleaning solution. They conclude the activity by using the newly made cleaning solution to...

When water is a solvent in a chemical equation, we consider it an aqueous solution. Scholars match the name of four states of matter to their proper symbol in a chemical equation. Four puzzles provide repetition to help pupils remember...

Create a model to study a microscopic phenomenon. The seventh of 12 lessons uses an egg (without its shell) to represent a cell membrane. Using different solutions, learners explore the concept of cell diffusion. They monitor...

Many scientists attempted alchemy for hundreds of years before a full understanding of metals became clear. Scholars take a penny and, through two different chemical reactions, make it appear to turn into silver and later gold. They...

More than half of AP Chemistry test takers earn a high enough score to get college credit. Improve that statistic by using past test questions including precipitate, molarity, and chemical equations to prepare for a future exam. The...

Beginning biologists place a drop of food coloring into water of differing temperatures to observe the effect on the diffusion rate. They remove the shells from raw eggs and then experiment with osmosis over the remaining membranes....

If you are delving into organic chemistry with your class, here is a practical resource to assign as homework. It is a chart of 15 organic compounds for which learners fill in the name, line formula, and the complete and condensed...

It may take up less space, but the mass stays the same. Tackle a common misconception about conservation of mass using a hands-on lesson plan. Learners measure the mass of substances before and after melting, dissolving, and undergoing a...

Colorful chromium is captivating! Science sleuths solve a series of puzzles using an interactive resource. Individuals relate the oxidation states of chromium to the colors produced when the compound is placed in acidic or basic solutions.

Introduce your chemistry scholars to the periodic table's Goddess of Beauty! Through an interactive that highlights the transition metal vanadium, learners discover the colors produced in solution as vanadium changes oxidation state....

Elements, to the rescue! Scholars first review the periodic table, and then learn about the first 20 elements and their properties and uses in the fourth of six lessons in the Mixtures and Solutions unit. Applying their newfound...

Investigate the reaction between four unknown substances using a virtual activity. Eager chemists examine the reaction between the four solutions to build a stoichiometric equation. The virtual workbench provides the tools necessary to...

Textbook problems with a twist! Young chemists analyze an ionic reaction to identify the limiting reagent. They then make calculations to determine the concentration of unknown solutions. Finally, they put their work to the test and...

Can you mix two liquids to make a solid that is insoluble? Yes, you can, and pupils see this as the instructional activity uses more than one combination of liquids to form a solid. Through two teacher demonstrations and a...

Most things naturally strive for balance, and acids and bases are no exception. Neutralization of acids and bases allows scholars to explore the color changes associated with the pH scale. After this exploration, pupils neutralize two...

Students investigate diffusion using different solutions of chemicals placed in agar dishes. In this diffusion lesson plan, students observe 3 demonstrations of diffusion using perfume, food coloring in water and sugar cubes in water....

Students recognize whether a solution is an acid or a base. In this acids and bases lesson plan, students use chemicals and identify if those chemicals are acids or bases. From the conclusion, students will be able to identify if the...

Students participate in lab activities in which they examine immersion, stain resistance, and stress cracking of synthetic polymers. Students use their collected data to discuss service applications and possible performance of materials.

Explore the chemical components of water through an electrolysis reaction. Scholars use a battery to divide various water solutions into different gases. As they collect the gases, they measure the volume and make a comparison to the...

In this chemistry worksheet, students fill in the chart for question one. The chart is filled out examining the mass, protons, electrons, and neutrons for specific atoms.

Decide on the most efficient plan to supply drinking water. The second project-based learning task in a two-part series builds upon the first project. Pupils revisit the wells to supply drinking water, but they must make sure the...

Let the data tell the story. A lab activity has pupils collect temperature data on solutes as they melt and freeze. They use their data to create a cooling curve and then calculate the molar mass using the freezing point depression.
