Middle School Chemistry: Chapter 3 - Density
Chapter three in the middle school chemistry unit explores the relationship between volume and density. Young chemists conduct experiments to find volume through displacement, observe how temperature affects water density, and how the...
Lesson Planet
Middle School Chemistry: Chapter 2 - Changes of State
The second module in the middle school chemistry unit looks at changes in the states of matter. Middle schoolers observe heat transfer, build molecular models of water from Styrofoam, conduct controlled experiments with condensation and...

Equilibria—Gifted and Talented Chemistry
Teaching is a balancing act! Keep things on an even keel with a comprehensive equilibrium lesson plan. The resource covers reversible and irreversible reactions, Le Chatelier's Principle, and the industrial applications of equilibrium...
Lesson Planet
Heat Transfer and Cooling
Astronauts train underwater to simulate the change in gravity. An out-of-this-world unit includes three hands-on activities, one teacher demonstration, and a discussion related to some of the challenges astronauts face. Scholars apply...

Can Gases Dissolve in Water?
Why does soda fizz when opened? Learners discuss the appearance of bubbles in soda bottles when opened. In groups, they design and complete an experiment comparing the amount of carbon dioxide dissolving in cold versus hot liquids.
Lesson Planet
Carbon Dioxide Can Make a Solution Acidic
Can your breath change the acidity in a liquid? A lesson plan begins with a demonstration that proves it can. Then scholars perform an experiment to determine if other gases can change the pH of liquids. Finally, they research how this...
Lesson Planet
Neutralizing Acids and Bases
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...
Lesson Planet
pH and Color Change
Did you know strong bases can feel slippery and slimy? Lesson allows scholars to practice using the pH scale to identify acids and bases and their strengths. By changing the concentration of an acid and a base, they create the entire...
Lesson Planet
Using Chemical Change to Identify an Unknown
If you discover an unknown powder, how do you determine if it is safe? Lesson uses four different tests to identify the properties of various powders that appear the same. Then scholars get an unknown powder and have to determine which...
Lesson Planet
A Catalyst and the Rate of Reaction
More than 90 percent of chemical products are made using a catalyst. Lesson demonstrates the way a catalyst changes the rate of reaction without altering the chemical reaction. A catalyst doesn't appear as a reactant or a product, yet it...
Lesson Planet
Temperature and the Rate of a Chemical Reaction
Putting glow sticks in the freezer makes them last longer, but why is that? Lesson focuses on how temperature impacts the rate of a chemical reaction. It begins with a teacher demonstration, then scholars design their own experiments...
Lesson Planet
Forming a Precipitate
Can you mix two liquids to make a solid that is insoluble? Yes, you can, and pupils see this as the lesson uses more than one combination of liquids to form a solid. Through two teacher demonstrations and a hands-on activity, scholars...

Controlling the Amount of Products in a Chemical Reaction
Everyone enjoys combining baking soda and water. Here is a lesson that challenges scholars to analyze the reaction three different ways — the real substances, the chemical equation, and the molecular models. Class members experiment to...
Lesson Planet
Temperature Affects Density
Different substances can have different densities, but can the same substance have different densities? Lesson explores the effect of temperature on the density of water. Extension idea connects the concept of how melting ice in lakes...

Density: Sink and Float for Liquids
We don't think of liquids as floating typically, but a quick look at any oil spill tells a different story. Lesson explores various densities of liquids and why this fact is important. After observing the density variation, scholars...
Lesson Planet
Density: Sink and Float for Solids
Steal cubes sink, but steal ships float. Lesson explores the density of solids as well as the density of water in determining what will sink and what will float. A hands-on group activity helps pupils see that weight and volume are two...
Lesson Planet
Density of Water
We know solids have a density we can measure, but what about liquids? Lesson explores this concept and allows scholars to explore the relationship between volume and density. Graphing and analysis questions round out the activity.
Lesson Planet
Finding Volume: The Water Displacement Method
We have formulas for finding the volume of geometric shapes, but what if the shape is irregular? Lesson describes how to find volume through water displacement. After a demonstration, scholars practice in small groups. Then analysis...
