January 8 and 9
Objective: Differentiate between a pure substance and a mixture.
Use the characteristics of different substances to separate them from a mixture
DO NOW: How would you define a substance? What makes one substance different from another?
Plans:
Go over qualities of a substance that students listed in their Do Now
Discuss water and ethanol differences, bring up solubility
Show students that sugar dissolves in water but not ethanol
Discuss mixtures- how mixtures can have variable compositions
Have students make a prediction about what will happen when we add sugar to a 50/50 mixture of water and ethanol
Discuss different separation methods
Have students try to separate a mixture of salt, sand, and iron filings
After lab, discuss water, show that electrophoresis can split water into two different gasses (http://www.youtube.com/watch?v=OTEX38bQ-2w) Water is a compound- it is made up of two smaller types of particles but it stays in a fixed composition. Those smallest unique types of particles are known as elements
Show video of sulfur and iron/ iron sulfide (http://www.youtube.com/watch?v=p5gf-odaxKA )
Have students whiteboard what the mixture looks like and what the substance looks like
Draw a diagram of element,compound, and mixture so students have a model of what these different categories look like

January 10 and 11
Objective: Students understand that compounds are fixed ratios of elements bonded together. Students know how to read a chemical formula
Do Now: Have two chemical compounds on the screen. What do these formulas tell us?
Lesson: Introduce John Dalton and the first atomic theory
Dalton’s Atomic Theory
1) All matter is made of atoms. Atoms are indivisible and indestructible.
2) All atoms of a given element are identical in mass and properties
3) Compounds are formed by a combination of two or more different kinds of atoms
4) A chemical reaction is a rearrangement of atoms
Relate these four points to the water electrophoresis experiment we watched last block.
Regard the question: How do we know water is made of two atoms H and one atom of O? Complete worksheet 2 as notes
Give time in class to work on review worksheet
Assignment: Review worksheet, group quiz next block

January 29 and 30
Objective: Students can write the names and formulas for simple ionic compounds
Due: Ionic and Covalent substances worksheet
Lesson: Review what an ionic compound is
Conductivity experiment
Discuss how “ions” are atoms that become charged- ionic substances are neutral but when they are dissolved the atoms separate and you can see that they are charged
Ionic substances however, share their electrons and so molecules have a stronger bond to them
Draw two models at the particle level- one of sugar and one of salt. Ask class which one is which. Class models depicting difference of salt and sugar
Melting point of sugar and salt- ask students based on their model which one would melt (or burn) fastest à test it!
