Here is a unique assigment: compare and contrast ionic and covalent compounds in an extensive data table and then analyze Lewis dot structures in antoher. Three columns are to befilled in: "characteristic or feature," "applies to ionic...

Believe it or not, it is possible for liquids and solids to get along! A hands-on lesson has individuals explore dissolving properties of candies in water. They complete an activity guide to record observations about different candies...

It's time to test observation and dissolving skills! After investigating the process of dissolving in previous lessons, pupils see if they can use their dissolving skills to identify substances. They dissolve known and unknown substances...

Sometimes liquids just don't get along together. A fun experiment has scholars determine whether various liquids dissolve in water. They pour isopropyl alcohol, vegetable oil, and corn syrup into cups of water to see which ones mix well...

Learning ... how sweet it is! A hands-on lesson uses colored candies to demonstrate how positive and negative charges interact. Pupils use different types of liquids and watch as the color from the candies spreads—or doesn't. 

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. Learners measure the mass of substances before and after melting, dissolving, and undergoing a...

From solid to liquid and then back again. Young scientists  dissolve salt in water and then evaporate the water while observing what happens to the solute. They use their observations to make predictions about other solutions.

Here's a sweet lesson plan to explore solutes and solvents. Using candies and water, learners observe properties of parts of the solution as the candies dissolve. They then modify the setup and note variations in the solution. 

Can your scholars solve the mystery of why salts dissolve? A virtual workbench allows them to experiment with temperature and solubility with no solution prep and no post-lab clean up! Users determine the solubility of a variety of...

Why does like dissolve like? While in many cases opposites attract, the same cannot be said for chemistry! Solution scholars take an up-close look at the dissolving process with a customizable interactive. The resource allows users to...

What happens to substances when they dissolve in water? Young scientists investigate the dissolving process with a colorful interactive. The resource illustrates changes in potential energy as solute particles interact with water...

Is your chemistry class finding it hard to concentrate these days? Give a short molarity video a try! Pupils learn the basics of the molarity calculation as they work along with the narrator.

Scholars learn about ionic substances, but how often do they encounter them in their daily lives? The final video in a six-part series explains ionic substances are more common that most people realize. The narrator discusses the...

This rock is on a roll! Introduce young geologists and environmentalists to the many uses of limestone using the fifth installment in a series of seven. Illustrate the components and properties of cement, mortar, and concrete, all while...

When making sweet tea, why do people dissolve the sugar in hot tea instead of cold tea? The class discusses the previous lab and builds upon it. Working in groups, they design an experiment to determine how temperature affects the...

Plop, plop, fizz, fizz, oh that one is the fastest. The teacher demonstration is the second part of a four-part series. The class observes how different pill types dissolve in simulated stomach acid. They determine which one dissolves...

Scholars first learn about Le Chatelier's principle with a two-video set. They then apply their knowledge to a short quiz. 

In the summer of 1815, snow fell every month in New England. Was this related to the volcanic eruption of Tambora in Indonesia earlier in the year? Young scientists design their own experiments to research the long-term effect a volcanic...

My name is Bond, Hydrogen Bond. Written for distance scholars working on chemistry at the high school level, the lesson includes eight weeks worth of material divided into six parts: substances you use, mixing it up, your skin, what's...

Focus on inquiry-based learning in your science class with a series of activities designed for middle schoolers. A helpful packet samples four different texts, which include activities about predator-prey relationships, Earth's axis and...

Third and fourth graders engage with a worksheet designed to help them differentiate between melting and dissolving. After reading an informative paragraph about the two actions, they consider four scenarios, and choose whether they...

Turn your class loose to experiment with the different fat content in skim milk, whole milk, half and half, and heavy cream. This is a visually vibrant experiment, as learners drip food coloring on the surface of the products and measure...

As part of a unit investigating the dissolving of M&Ms® candy coating, this instructional activity examines whether or not the different colors combine. There are no new concepts revealed in this particular instructional activity,...

Little chemists address whether or not you can get sugar back out of tea after it has dissolved. The PowerPoint itself simply walks them through the questioning process, considering different possibilities. The final slide settles on...
