 Liquid Nitrogen Frozen Gummy Bears

My most popular video. Lots of annotations 

provide extra science information! 

I also explain some ways science uses

Liquid Nitrogen! 

 Cats in Sinks: A Science Lesson

An internet website showing cats in sinks led

me to wonder, "What is the best way to determine

how many cats will fit in a large lab sink?" 

I have some help from a couple of young people.

I explain Theoretical vs. Experimental

methods plus the use of models in science. 

Gummy Bears Demonstrate

Osmosis and Crystallization

A happy accident of trying to make these

insulators conductive to electricity shrunk a bear

and causes crystals to crash out of solution!

 Determining the Mass/Length of Gummi Bears

How to set up a lab notebook, use a balance and

calipers. The difference between accuracy and

precision, weight and mass, and more! 

Sonicating a Gummy Bear

The video that started it all.

A student wondered

if a gummy bear could be sonicated,

so I obliged with an experiment!

I explain how scientists use

sonication in the cell biology lab, too!
