What are the five phases of matter? Describe the atoms in each state of matter?
Lab Color Periodic Table Adopt an Element Notes Go over atom worksheet for yesterday
Today’s Activities
Use Alien cards to organize them into groups
How can you organize them? Show me what you have done
Now organize them into rows and columns How do they have fit together? What have you seen like this?
Periodic Table Lab
Get computer, if you remember what number
you used for matter lab, use that computer Log in Once log in, go to the following website
www.ptable.com Play with website and see what you notice
Lab
Color Periodic table according to metal,
nonmetals and metalloids on the website Then select an element you would like to
“adopt” Let me know what you choose, I only want one
group doing an element Fill out worksheet
Make facts interesting for the whole class I am going to ask you to share 2
Lab
Warm-up
Finish atom paper Go over atom worksheet Take notes over Periodic Table
Very quick, small amount Reading
Highlight Video Notes Worksheets
Today’s Activities
Periodic Table of Elements
Columns Grouped by having similar physical and
chemical properties 18 groups in total
Groups (Families)
Rows Going across, the number of electrons in the
outer shell Same number of electron shells 7 periods
Periods
Back in HistoryWe used to think that there were only 4-5 elements. This was before we
found out that these elements, like water, had even smaller parts.
What is a molecule? How are molecules
formed? Molecules form when atoms are
chemically joined together and are made up of two or more atoms
Molecules
What is an element?
When a molecule is only made up of one type of atom
What are 2 types of molecules are there? Compounds and elements
Example of an element atom Ar, Ne
Example of an Element molecules O2, N2
Elements
What is a compound?
Molecules that have more than one type of atom
What is a compound made of? Same as above, leave blank
Give an example of a compound molecule CO2, H2O
Compounds
What is a mixture?
Composed of two or more substances which each keep their original properties and do not combine chemically.
What can mixtures be made up of? Salad, brownies, salt water
What is air (atmosphere)? A mixture because it contains different
elements and compounds but each have their own properties
Mixtures
Warm-up
What is the difference between a compound and a mixture?
What is the difference between an atom and a molecule
Finish worksheet and complete new worksheet Go over worksheet “All Mixed Up” Matching cut outs
