Middle School Chemistry: Chapter 5 - The Water Molecule and Dissolving
Through demonstrations, hands-on activities, and discussions, young chemists explore water molecules and their polar characteristics. Groups design and carry out their own experiments to examine solubility, determine if the type of...
Lesson Planet: Curated OER
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: Curated OER
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...
Lesson Planet: Curated OER
Middle School Chemistry: Chapter 1 - Solids, Liquids, and Gases
The five lessons in the first module of the Middle School Chemistry unit focuses on solids, liquids, and gases. Young chemists use science to explain what appears to be magic tricks, build thermometers, study the impact of temperature on...
Lesson Planet: Curated OER
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...
Lesson Planet: Curated OER
Global Warming: Facts and Our Future
According to the United Nations, climate change affects every country on the planet. This research project encourages scholars to explore the factors that affect climate change from different perspectives: climate scientist, policy...
Lesson Planet: Curated OER
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: Curated OER
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: Curated OER
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: Curated OER
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: Curated OER
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...
Lesson Planet: Curated OER
What is Density?
Density: the reason a giant pumpkin will float, but a tiny cranberry won't. Lesson begins with a demonstration of two of the same-sized cubes having different densities. Then pupils take eight cubes, each of the same size, and have to...
Lesson Planet: Curated OER
Temperature Changes in Dissolving
Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...
Lesson Planet: Curated OER
Why Does Water Dissolve Salt?
Individuals explore solubility by modeling how water dissolves salts. They then view a video and compare how well water and alcohol dissolve salts, relating their comparisons to the structure of each molecule.
Lesson Planet: Curated OER
Surface Tension
A drop of dew holds a sphere shape even when sitting on a seat thanks to the surface tension of water. Learners observe the phenomena of surface tension in water. Through demonstrations, hands-on activities, and discussions they explore...
Lesson Planet: Curated OER
Can Liquids Dissolve in Water?
How does food coloring work? Classes watch a demonstration showing liquids dissolving in liquids. In groups, they then explore the ability of other liquids to dissolve in water (alcohol, mineral oil, and corn syrup) by setting up and...
Lesson Planet: Curated OER
Why Does Water Dissolve Sugar?
Did you know that if you wait long enough, the M on the outside of an M and M will float to the surface when submerged in water? Learners observe the sugar coating of an M and M while it is dissolving in water. They explain how this...
Lesson Planet: Curated OER
Water is a Polar Molecule
A water strider is a bug that taps into the attraction between the positive and negative ends of water, allowing the bug to walk on water. Learners view short videos showing polar characteristics of water. Pairs then discuss what polar...
