The author explains a virtual chemistry lab activity for use in a high school chemistry class. This activity is an excellent way to introduce measurements, significant figures, and the concept of density.
Science Practice: Using Mathematics and Computational Thinking
Using the online simulation tool (Atomsmith Classroom Online) and the ADI framework students investigate the properties of gases, along with two gas laws. An ADI "whiteboard discussion" helps in getting students to really process what the results of experiments mean to us as chemists - and how this leads to expanding our understanding of matter. This activity lends itself to an online classroom.
With the school year quickly approaching, science teachers will at some point need to decide the role of laboratory investigation within their new learning environment. To help this decision-making process, the author focuses on two available options that he believes have the greatest potential for offering a legitimate approach toward authentic investigations in a digital environment.
The Ruben's Tube (also known as a Flame Tube) is a classic experiment used in physics classes. There's also a bit of chemistry to be learned while experimenting with a Ruben's Tube...
This unique microscale gas collection technique provides students with reasonably good data in a short period of time. Students have more time to analyze the data and communicate their findings.
This experiment in chemical kinetics can be conducted using materials as simple as a smartphone, hydrogen peroxide, sodium carbonate solution, and blue food dye! The experiment is useful when discussing the order of rate laws with respect to reactants.
I had the opportunity to develop an advanced chemical lab design course for a small group of ambitious students. I have outlined the resources I used and how I pulled the course together,
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.
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.
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.
