Seventh graders investigate the scientific methods of testing the effectiveness of soap use against germs. They study the history and chemistry of soap as it has helped control the spread of germs. They make bubble soap.

Students study and examine crystal shape. They create the two basic unit cells (one a tetrahedron) out of pipe cleaners and dip them into soapy water to see if they can form bubbles to represent a silicon atom in the center of a...

In this work worksheet, students are given a picture of people in a Victorian street doing all different types of work. Students fill in bubbles with what each person may be thinking.

Students work in groups and observe chemical reactions inside zip-lock bags. They use all of their senses, except taste, to observe the reactions.

How are chemical reactions affected by gravity? Learners explore the phenomenon of effervescence as part of the Christa's Lost Lessons series. They compare findings in an experiment on effervescence to a video of a similar experiment in...

Where does the pop in pop rocks come from? An engaging activity asks scholars to measure the amount of carbon dioxide in a package of Pop Rocks candy. Learners dissolve the candy in water and use the solubility of CO2 to determine its mass.

If you are up for constructing a wooden frame, you can do this demonstration of the interference patterns when light reflects off of layers of soapy film. Both constructive and destructive interference can be seen as evidenced by the...

Create a little scientific magic within your classroom! Learners mix powders and liquids and identify chemical reactions. Based on the reactions, individuals determine the identity of various powders.

A fantastic presentation with great images should improve student understanding of lipids and their involvement in the body.  The chemistry of different fats, phospholipids, and steroids are explained. Additionally, the specific...

Here is a lab activity adequate for use with any full instructional activity on environmental factors that shape animal adaptations or marine animal characteristics. Pupils will discuss the role plankton plays in the environment and...

What a wonderful resource! This presentation describes key vocabulary and information relating to volcanoes. The visuals are inviting and the descriptions useful. It provides everything a teacher needs to introduce or review this topic...

If you aren't part of the solution, you are part of the precipitate! Young chemists learn about single and double displacement reactions including precipitation reactions, neutralization reactions, and gas forming reactions. They perform...

A fantastic presentation with great images should improve student understanding of lipids and their involvement in the body.  The chemistry of different fats, phospholipids, and steroids are explained. Additionally, the specific...

Researchers use scientific data to understand what is inside each of the planets. The first in a series of six, this lesson builds off of that concept by having pupils use a data table to create their own scale models of the interiors of...

All of the gas giant's atmospheres consist of hydrogen and helium, the same gases that make up all stars. The third in a series of 22, the activity challenges pupils to make scale models of the interiors of planets in order to...

Ever made solar s'mores? Or recreated the solar system using peanuts? Astronomers young and old investigate all things solar using a variety of activities. Explore how the sun works, types of light it emits, and methods of charting the...

Little chemists observe the effects of acid on calcium carbonate as an example of chemical change. As a demonstration you will place a raw egg in vinegar overnight, and as a lab activity, learners drip vinegar onto a piece of chalk....

Why don't we just capture carbon dioxide in the air and store it somewhere else? A hands-on instructional activity allows scholars to explore a complex concept. First, they will create a carbonated beverage, and then they...

After listening to a story about the water cycle, learners create their own versions of this tale. This is a great way to have your class review the concepts of evaporation, condensation, precipitation, and runoff.

Although the worksheet for the lab activity is not included, this is an activating activity for your class to do when learning about the greenhouse effect. They lay three thermometers underneath a lamp: one out in the open, one under a...

The arctic seas contain currents that are both warm (with high salinity) and cold (relatively fresh water) that circulate throughout the year. Through discussion, a lab, and a web quest, participants explore the impacts of melting and...

I love big mural projects. They bring a sense of ownership to the classroom, look great for parents, and can be a great way to complete a unit. Here are the steps and suggestions needed to create an ocean mural for your class. Learners...

The scientific method is emphasized in this engaging and exciting chemistry lesson. Learners get to create Alka-Seltzer cannons out of film cannisters, water, and Alka-Seltzer tablets. Carbon dioxide gas builds up inside the cannister,...
