Elements and The Periodic Table Year 1 Sciences

Pre-Note Activity (KWL) K- write down what you already know about atoms and the periodic table W- during the videos, write down questions you may have (what you want to know) L- after the videos, write down what you have learned Study Jams: Protons, Neutrons, and Electrons (Review) Study Jams: The Periodic Table BrainPOP- The Periodic Table

Note Taking Expectations notes must be written neatly letters should not be too BIG! write on each line, unless instructed to skip a line for another section have a puke page on standby: if you run out of room on the first page, then continue writing on the puke page (glue after the presentation!)

Atom: the smallest part of (INB pg. 9) Atom: the smallest part of matter that still has the same properties of its element.

Element: substance made up of the same atoms combined (INB pg. 9) Element: substance made up of the same atoms combined examples→ gold, helium, aluminum

Brain Break! Discuss with your group: What is the difference between atoms and elements?

(INB pg. 9) Periodic Table: table where elements are organized by increasing atomic number (# of protons).

(INB pg. 9) In the late 1800s, Dmitri Mendeleev devised the first periodic table based on atomic mass. In 1913, Henry G. J. Moseley arranged elements by atomic number and is what we use today.

REVIEW

The periodic table is arranged by groups and periods. (INB pg. 9) The periodic table is arranged by groups and periods.

(INB pg. 9) Groups : vertical columns of elements with similar properties - groups are numbered 1-18.

(INB pg. 9) Periods: horizontal rows of elements that contain increasing numbers of protons and electrons. Periods are numbered 1-7.
