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: Engaging in Argument from Evidence
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.
I facilitate a working group of chemistry teachers in the New York area and we recently created our own activity surrounding the topic of oxidation. The goal of the probe was to force students to think about what the meaning of oxidation is, as well as to allow students to engage in the science and engineering practice of argumentation. This was an introductory lesson to my oxidation and reduction unit prior to students learning the terms oxidation and reduction.
Use Mega M&Ms, M&Ms minis, and regular M&M’s in this activity to examine the concept of isotopes and average atomic mass. The color of the M&M’s represent that they are the same element and have the same number of protons. The size represents, in a relative sense, the different numbers of neutrons.
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.
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!
Like most concepts in chemistry, intermolecular forces takes a bit of imagination and critical thinking to fully comprehend and apply when explaining a variety of situations. Though demonstrating the presence of these forces in a simple and explicit manner can easily be done, I wanted to change how I introduced IMFs a bit this year by focusing on a more data-to-concepts approach.
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.
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.
