Finding Volume: The Water Displacement Method

For Teachers 6th - 8th Standards
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...

What is Density?

For Teachers 6th - 8th Standards
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...

Phase Change: What Does Hot Cocoa Have to Do With Chemistry?

For Students 9th - 12th Standards
Hot cocoa is easy to make with only two ingredients, so what does it have to do with chemistry? The lesson begins with what seems like an obvious question. Then scholars perform simulations to focus on phase changes. Lastly, they...

Gas Laws: What Can a Basketball Teach us About the Gas Laws?

For Students 9th - 12th Standards
Ever have a tire or basketball that has no leaks go flat? The lesson starts with that scenario and scholars use a simulation on the computer to learn about three gas laws. The next day, hands-on experiments reinforce the same concepts.

Kinetic Molecular Theory: What Can a Spray Can Teach Us About Chemistry?

For Students 9th - 12th Standards
Ever left a can in a hot car and had it explode? Scholars complete an online simulation in which they choose the dependent and independent variables related to kinetic molecular theory. Then after a brief lecture, pupils complete an...

Diffusion: What Can Popcorn Teach Us About Diffusion?

For Students 9th - 12th Standards
Why do some smells, like popcorn, linger when others seem to vanish as quickly as they arrive? Learners think through that concept then complete an online simulation to determine if temperature and/or mass affect diffusion. Next, pupils...

Changing State: Melting

For Students 6th - 8th Standards
Dry ice is extremely cold — it is -109.3°F or -78.5°C. Scholars observe and explain the molecular motion associated with melting. Then they design their own experiments to speed up the melting process. Finally, a teacher presents a...

Changing State: Freezing

For Students 6th - 8th Standards
There are five types of frost: ground frost, air frost, hoar frost, glaze, and rime. Scholars mix ice and salt in a metal container to observe frost forming on the outside of the can. Animations and videos enhance the learning. 
Lesson Planet

Changing State: Evaporation

For Teachers 6th - 8th Standards
Why do experiments require a control? Guide scholars through designing an experiment to see what they can do to evaporate water faster with a lesson that stresses the importance of controlling all variables. The second activity allows...
Lesson Planet

Heat, Temperature, and Conduction

For Teachers 6th - 8th Standards
How does heat move from one item to another, even when the items are in different states of matter? Pupils experiment with adding washers to hot water and adding hot washers to room temperature water to observe the heat transfer. 
Lesson Planet

Biological Oceanographic Investigations – Call to Arms

For Teachers 5th - 6th Standards
How many simple machines does it take to make a robotic arm? An inquiry-based lesson explores that topic and challenges pupils to build a robotic arm that can stretch, turn, and more. A few questions help guide them in the right...

Why We Love Sugar

For Students 9th - 12th Standards
Now that's sour! Did you know lemons contain more sugar than strawberries? Here is a resource that helps pupils explore sugar, where it comes from, different types, why organisms need it, and how much we ingest.

The Science of Overpopulation

For Students 9th - 12th Standards
The population of the US increased 300 percent in the 20th century, but the use of raw materials increased by 1,700 percent. Explore human population growth over time with a video that examines the history of why such growth has occurred...

Ebola Outbreak

For Teachers 6th - 12th Standards
As of April, 2016, more than 28,000 suspected cases of Ebola were recorded in Western Africa with over 11,000 human deaths. Classes discuss the Ebola virus outbreak in 2014 and then groups develop an action plan based on research,...

Simplified MRI

For Teachers 9th - Higher Ed Standards
Cancerous tissues contain more water than normal tissue, which causes the cancerous tissue to resonate longer on the screen and be seen. High school learners can see how MRIs detect tumors in someone's head. Radio transmitters emit their...

Sugar and Salt Solutions

For Students 6th - Higher Ed Standards
Ionic bonds form from electrostatic energy, allowing for higher conductivity than those seen in covalent bonds. In the simulation, learners add sugar and salt to water and see the effects on concentration and conductivity of their...
