Last week marked the introduction of elements, compounds and mixtures. I always like to begin the unit with an activity that will make my students pose questions and raise their level of curiosity. One great activity that I came across by Flinn Scientific, Inc. is titled “Classifying Matter: A Nuts and Bolts Demonstration”. Click here for a copy: Nuts and Bolts Activity What I like about this activity is that you are representing elements, compounds and mixtures with bolts, nuts and washers. You provide the students with different scenarios such as: all bolts, or bolts with nuts attached or bolts with nuts attached and scattered washers. Students are a little confused at first when you ask them to identify which ones represent elements, compounds or mixtures but they quickly pick up on the pattern and enjoy the activity. After, I give them the short quiz, which is provided on the second page of the attached activity and have them work in teams to see who can correctly identify the most scenarios (this time using shapes). For homework, since my class is flipped, I assign a video that defines elements and compounds and explains where they are located on the periodic table. See my flipped video below for more information.
After watching the video, I want my students to become even more engaged with the periodic table. The next lesson does just that utilizing the power of augmented reality. Using DAQRI’s Elements 4D Blocks, students now have the ability to manipulate elements they could never see in a middle school science laboratory setting. Today, my students scanned up to 36 different elements and discovered concepts such as location of the periodic table, color, state of matter and classification.

Tomorrow we will be making pyrite! Looks like an exciting unit in science. Stay tuned and thanks for reading!
