Today we discussed the lab activity that we will do tomorrow.
Handouts
Remember all our discussion about safety precautions. I will expect you to treat safety as the first priority when we are conducting the lab.
We then went through the lab procedures together to ensure that you understand the topic we are investigating. During a chemical reaction we expect mass to be conserved throughout. This means the total mass of the products is the same as the reactants. We will investigate if this is true when we perform a reaction in a closed container and in an open container.
We took some time to write down our hypothesis.
Then we looked at the procedures to make sure that you are familiar with all the equipment we will be using.

| Here's the setup for part A of the lab. |
Finally, we discussed how to describe the appearance of chemical solutions. Try describing milk and water using the proper terminology. Which one is transparent or opaque? Which one is colourless or white? Which one is more viscous? Which one is liquid?

Be prepared to conduct the lab tomorrow!
