Does Dye Die...? : Foreign Chemicals In Our Environment

If you have taught the first lesson in this mini unit, learners already know that cabbage juice and vinegar cause chemical changes in some materials. Now, they get a chance to use them to compare the liquids' reactions to five known and...

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...

After a discussion of chemical reactions and electricity, scholars break into groups and follow a scripted activity to discover if fruit can power a clock. After a concluding discussion, the class a presented with a challenge.

Through the analysis of paper chromatography to separate ink from the pen found at the crime scene, learners analyze the different stains and through calculations determine the thief. 

High schoolers use chromatography to separate plant pigments collected from a fictitious crime scene and suspects. They compare the Rf values of the plant pigments to determine whether the plant pigments found on any of the suspects...

Do you think chromatography paper suffers from separation anxiety? Young chemists make soap, slime, silly putty, and experiment with chromatography in this lesson. The material includes clear instructions for each experiment along with...

Why does a plant grow toward the sun? The video, part of a Fuse School Plants playlist, explains the chemical processes behind plant growth. It details how auxins, gibberellins, and the sun work together. From curving plant stems to...

Polyatomic ions... where do I begin? One of the most difficult concepts for budding scientists to learn and recognize comes to life in an enlightening resource. Show pupils some demonstrations, via the sixth video in a series of 10, to...

The anode, the positive electrode, attracts negative charges, which is why we call negatively charged atoms anions. The interactive allows pupils to match six different anions to the associated properties when testing. Offering four...

Four percent of the world's CO2 emissions come from the chemical industry. The video discusses the environmental impact of industry. From using non-renewable resources, requiring high levels of energy, to polluting the ground, water, and...
