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.
Science Practice: Asking Questions and Defining Problems
Use a simple experiment to get to know students, demonstrate experimental design and discuss classroom policies about cell phones.
Why does the "Whoosh Bottle" experiment behave differently at different temperatures?
In this lab, students are presented with nine unknown substances. By performing a series of tests, analyzing chemical structures, and applying their understanding of how intermolecular forces affect the properties of a substance, students will ultimately determine the identity of each unknown.
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.
Michael Jansen runs this engaging "big picture" lab on day 1 of Grade 11 Chemistry, which is the students' first dedicated Chemistry course.
Recently, Josh Kenney took time from his regular scheduled chemistry curriculum to investigate a student's claim that chocolate cake was an acid-base indicator.
This is a simple small-scale distillation that can be used several different ways.
