Moving on to Chemistry
You’ve spent a couple of weeks studying global climate change and some pretty high-level science, including the IPCC report I showed in class. You should have some good notes from class including the drawings and table of greenhouse gases. In addition last Friday we did a summary and I provided you with a long list of web resources.
Be sure you are studying for your test on Friday and complete your poster project due 4/11.
Now we have begun our study of chemistry. A little introduction last week with a video and a fun Hershey Kiss lab today. Remember the lab write-up is due Thursday. Tomorrow we’ll take a closer look at atoms and the periodic table.
Grade reports will be sent home with you tomorrow.
what kind of question of key question would u be looking for lyk how the diffrent methods dissolved and if there was a diffrence in the time periods or are u looking for somthing else?
on this pariticular lab i dont get wat our back ground is supposed to be about or do we not do it
You’re on the right track.
how do we do the back ground for this lab , im lost
can give a hint on how to do the background section of the lab ?
My earlier comment “you’re on the right track” was directed to anonymous who asked about the key question.
Your background information should be about your key question. Your key question should be about what you are measuring.
In this experiment you measured how long it took for the Hershey kiss to dissolve (i.e. the rate it dissolves).
So you want your background to be about dissolving things and what might change the rate at which something dissovles.
I also had 3 words on the front board for you: solvent, solute and solution.
