The Bond Breaker lab activity is a very fun and hands on lab for students to compare the strength of ionic and covalent bonds.
In this very affordable (only costs a few dollars for ice, salt, and sugar), quick, and easy set-up lab you will provide students with three different substances (Ice, Salt, Sugar). The students are asked to answer the question in the lab are ionic or covalent bonds stronger and must create a procedure to test their hypothesis.
You will need to provide students with bunsen burners or hot plates in order to heat up each material. My students LOVE to use bunsen burners just because there is fire involved. Safety is paramount in this experiment as they are using heat.
I have attached a teacher lab activity guide/answer key to the end of the document so that you can quickly understand how to carry out the lab and what results the students should be getting.
This lab is a great way for students to explore ionic and covalent bonding which is content that is difficult to create or find a hands on labs and activities.
Bag of sugar
Bag of ice
Bunsen Burner or Hot Plate
Beakers or Test Tubes
Enjoy and Godspeed!
