Chemistry Labs, Week 10

This week the kids completed two experiments:

• Experiment 4.4: The Kinetic Theory of Matter
• MicroChem Experiment 2: Melting Points, Super Cooling

Chemistry Labs, Week 9

This week the kids performed the experiment 4.2: Distinguishing Between Chemical and Physical Change.

The kids dissolved an egg shell with hydrogen chloride (toilet bowl cleaner). The reaction is awesome, but beware - it stinks! Make sure you have good ventilation in the room.

Chemistry Labs, Week 8

This week, the kids performed experiment 4.1: Separating a Mixture of Sand and Salt

Chemistry Labs, Week 7

We took a break this week from our chemistry labs. {I was suffering from a migraine} So, the kids will double up next week to stay on track with the lab schedule.

Chemistry Labs, Week 6

This week the kids performed two science experiments:

• Experiment 3.2 - Electrical Conductivity of Compounds Dissolved in Water
• MicroChem Lab 3 - Electrical Conductivity of Several Solutions

The wire initially emanated bubbles, but after a few minutes the copper started turning into copper sulfate - CuSO4.

Chemistry Labs, Week 5

This week the kids completed the lab for experiment 3.1:
The Conservation of Mass ~ mixing vinegar and purple cabbage juice (chemical reaction #1), then added lye (chemical reaction #2). The second reaction also created heat. The kids really liked this experiment.

Chemistry Labs, Week 4

This week the kids completed the lab for experiment 2.2: Measuring the Specific Heat of a Metal.


We also spent time going over the math problems in the module. They are finishing up module 2, taking the module test and starting on module 3.

Chemistry Labs, Week 3

This week the kids completed experiment 2.1: Calibrating Your Thermometer
We discovered that our thermometer was off by 1 degree.

They also viewed the following websites:

• Significant Figures Fable: http://chemteam.info/SigFigs/SigFigsFable.html
• Powers of 10 Demonstration: http://micro.magnet.fsu.edu/primer/java/scienceopticsu/powersof10

Chemistry Labs, Week 2

The kids completed two experiments this week.

Experiment 1.3: Comparing Conversions to Measurements - math based experiment
~and~
Experiment 1.4: The Density of Liquids - classic density experiment with math & measurements.
