This empowering activity provides students the opportunity to drive their own lab experience. It allows students to perform research, execute lab techniques and identify an unknown substance.
Some metals and metal alloys undergo a transition to brittleness at cold temperature. This phenomenon likely contributed to the demise of the Titanic.
This lab guides students through taking data and constructing their own heating curve for water. It requires no special equipment, is low prep, is safe, and can even be done at home for homeschool or distance learning. Even though the lab activity itself is relatively simple and straightforward, the concepts still engage students in higher level thinking and gives them important practice with laboratory techniques and forming hypotheses.
Use a simple experiment to get to know students, demonstrate experimental design and discuss classroom policies about cell phones.
You can solve Chemical Mystery #20 if you know your chemistry...and your magic!
Why does the "Whoosh Bottle" experiment behave differently at different temperatures?
Can Alkaline Water Change the pH of your body? We use chemistry to put this claim to the test!
The "Two-Faced" thionin reaction involves causing a purple solution to fade to colorless by shining light on the solution. I wondered if it could be demonstrated the color of light that caused this transition.
