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.
Science Practice: Analyzing and Interpreting Data
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.
My district recently provided a professional development session focused on utilizing three dimensional formative assessments in the classroom. The ideas I learned in the session as well an an activity for students to engage in formative assessment are outlined.
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.
We all know how fundamental the mole concept is for stoichiometry. This year I brainstormed ways to really make it stick. I decided to do multiple mini-practicums, one for each learning target of the mole unit. I am sharing brief descriptions of the mini-practicums I did for each learning target.
I will share how I use the Target Inquiry activity, Change You Can Believe In. I have realized that I need to include particulate models within the assessments after the lab to fully evaluate my student's conceptual understanding.
Whether you are introducing collision theory or something more demanding like reaction order, the reaction between sodium thiosulfate—Na2S2O3 and hydrochloric acid can provide a consistent, accurate, and engaging opportunity for investigating these topics.
Last winter I watched a webinar put on by ACS and AACT called "NGSS in the Chemistry Classroom." As a result of watching that webinar, I took an activity that had NGSS Science & Engineering Practices (SEP) integrated into it and tried it out in class. In this activity, students are required to develop their own procedures and data tables.
