Videos 1 through 3 show lithium, sodium and potassium reacting individually with water. Video 4 shows all three metals reacting in side by side beakers of water (without voice over).

The ChemEd X video library also offers a series of videos that allow students to compare the reactivity of three alkali metals. Since I was able to access my lab, I created a video to share with my students (you can use this LINK to view). It was not ideal but provided the best option given our setting.

Since my class is virtual, the wet lab portion was achieved through video. The lab class can then concentrate on whats important and fun: doing chemistry. Teach or review chemistry fundamentals with cards. The virtual element cards are included in the Google Slide presentations. Periodic tables show elements arranged by atomic number, electron configuration and chemical properties. Most of these 16 cards do not show the atomic mass. In my class, students worked on this in breakout rooms and as before, there was a video to provide some gentle hints. As the instructor I provide the final checkpoint.Īccess the Pre-Lab assingment, the Google Slides presentations (including student instructions and instructional videos) and all related keys by logging into your ChemEd X account and downloading the Teacher Document from the Supporting Information below.

Students already have the first 10 cards sorted as in the previous Google Slideshow. They then complete the next two periods with the remaining 16 cards. This was more of a challenge. There is an “Unknown Card - Xx”. Several years ago this site featured an activity, Trend Setter Lab, that was developed as part of Target Inquiry. I have used “Trendsetter” for years with great success. The activity introduces relevant vocabulary that students have covered or will cover. There is a nice wet lab portion to the activity. The periodic table activity that features a relevant card sort that involves trends and patterns. One of the many reasons I like this activity is that the card sort involves searching for periodic patterns that actually exist. Many other similar activities involve a card sort that involves trends and patterns but they are about colors, symbols and / or drawings rather than real chemical properties. “Trendsetter” actually involves patterns and trends about electronegativity, atom radii, properties of reactivity and ionization energy. All of these are topics that students eventually will cover in depth. This activity provides a nice “frontloading” opportunity that other similar activities do not provide. A final advantage is that students are asked to predict these properties for a “missing element” just as Mendeleev did. As the students work through their reasoning, more often than not, they discuss their ideas much the same way as Mendeleev. Students eventually master multiple objectives with this one activity. I was reluctant to give this activity up when we went virtual. Below is an attempt at a virtual option.įigure 2: The first two periods of the periodic table students will organize. “What are we doing to try to help kids achieve?”
