If you are looking for ideas to create an authentic opportunity for students to apply their knowledge of gas laws while integrating some of the most important science practices, then this activity may fit your needs.
Science Practice: Constructing Explanations and Designing Solutions
Have you ever seen the liquid nitrogen cloud? Do you wonder how the cloud forms when hot water is thrown onto liquid nitrogen? This post explores the liquid nitrogen cloud and possible explanations for its formation.
In this activity your students will be introduced to the concepts of claim, evidence and reasoning. The activity is POGIL- like in nature in that no prior knowledge is needed on the part of the students.
The solution to "Chemical Mystery #16: A Red, White, and Blue Chemistry Trick for You!" is presented. How this experiment can be used as a springboard to carry out a simple quantitative analysis of salt solubility is also discussed.
Watch this video and see if you can figure out how red, white, and blue colors can all be made from the same chemical solution!
The solution to Chemical Mystery #15: The Leaky Cup is shown here.
This lab is one of my favorite activities to do in my classes and I look forward to it every year. The lab is simple, requires limited supplies, students love it (i.e. high engagement level), and I have found it to really set students up for stoichiometry.
Time for a new chemical mystery! Watch the video below and see if you can use your chemical knowledge to figure out how this experiment is done.
I was excited for the opportunity but I never thought my science coach would be interested in developing and executing lessons with me. Luckily for me, my experience ended up being nothing like what I expected. You can apply for this experience too. The deadline to apply for Science Coaches for the 2019–2020 school year is September 1, 2019.
Biosorption is a method that can be used for the removal of pollutants from wastewater, especially those that are not easily biodegradable. This experiment uses citrus fruit peels as part of a iodometric titration to conduct a wastewater treatment binding copper.
