Transcript of Warm Up

Do Now
1. Retrieve your lab notebooks from the crate and make a new entry into your table of contents marked "Vocabulary"
2. On the right side page make two Freyer model squares like the one on the board. On the left draw two circles in a Venn diagram.
3. Do this for the next pages as well.
Warm up
Using Lewis dot structures show the bonds for FeO2
Warm Up
1. Define these terms:
Heterogenous
Kinetic Energy
Homogeneous
Colloid

In your interactive journals:
1. Start a new page for the experiment: "Graph the heating curve of water." Put it in your T.o.C.
2. Begin the steps of the scientific method in your journals. Your question will be "What does the heating curve of water graph look like?" Try to guess in your hypothesis.
3. In your interactive notebooks (on a new page) create a table with slots for time and temperature.

Warm Up
1. Get your Lab notebooks out.
2. Make a new entry in your table of contents for History of Atomic Theory
3. Turn to that page and divide it into 4 sections.
4. Label Each section with a name from the board
Warm Up
1. A candle is placed on one pan of a balance, and an equal weight is placed on the other pan.

What would happen if you lit up the candle and waited for a while?
Design your own
Get together in small groups and everyone take out your Lab notebooks.

Make a new entry in your ToC called Design your own experiment. Turn to that page and answer the following questions.

How is the law of conservation of matter related to balancing equations?

What steps would you use to design an experiment to verify that matter is conserved in a chemical reaction?
2. Suppose the candle was placed in a large, sealed jar that allowed it to burn for several
minutes before running out of oxygen. The candle and jar are balanced by an equal weight.

In this situation, what would happen if you lit up the candle and waited?
