Review for:Brainiac Alkali MetalsIf you used this resource in your own classroom, please add your review. posted: on February 27, 2007 at 1:42PM
My rating of this resource: *****
My experience using this resource: Chemistry
Topic I was teaching: Reactivity of alkali metals - Periodic Trends in Reactivity
My learning goal for which this resource was used: To see that the reactivity of alkali metals increases as the principal quantum number increases.
Course Level: Honors or Advanced
How I/my students used the resource: We watched the clip and then discussed the reasons for the observed phenomena.
Value Added: Provides visualization or animation, Provides a virtual lab
Strengths: This is nice because it engages the students. I tend to not show many clips, so when I do they are interested. They saw that the reactivity increases, and are able to see reactions that I can not do in a class room.
Weaknesses: The clip does not include any information on the actual reaction taking place, 2 X + 2 H2O --> 2 XOH + H2. And did not offer an explanation on why the reactivity changes.
