Today we reviewed metals, non metals, and metalloids during our warm up. After our warm up, we reviewed the Groups on the Periodic Table from last class. Last class, the students completed the videos on the groups of the periodic table and took notes on each group.
We then moved on to doing an introduction lab on density. The lab involved calucluating the density of water at different volumes. Here are the conclusion questions:
1.The density of water is 1.0g/mL. Why do you think your calculated density was not 1.0g/mL?
2.As volume of the liquid increased, what happened to the mass of the liquid?
3.What do you notice about the density as you change the volume?
4.What predictions can you make about the density of water if you use 100mL?
Homework tonight is to pick any element on the periodic table (except Sodium and Helium) and write about any thing you can think of based on the periodic table. I do not expect you to research your element, just identify as much info as possible using the periodic table. Here are some suggestions.
•Atomic number
•Protons
•Electrons
•Neutrons
•Atomic mass
•Metal, non or metalloid
•Period number
•Group number
•Reactivity-how reactive is it and what makes it act that way
•Number of electron shells
•Which other elements does your element have similarities with?
This should be written in paragraph form, not list form!!
