The Week is Half Over!

Homework:-Enzyme chart with reading (also use section 33 in textbook)
-visit Mrs. Stein in her office for a homework pass!
-sign up for science contest (for extra credit)
-Nutrient lab due some time in class on Friday

First in class, we discussed nutrients and here's what we discussed...

I -testing for carbs-simple--SMALL, less energy
                          -complex--BIG, more energy (starch)

II -testing for protein---> amino acids

III -testing for fat (lipids)--->glyceol & fatty acids

IV - testing for food <UNKNOWN>

Nutrient Lab

Today, we got our new lab groups and STARTED the nutrient lab. We only did the starch part of the lab.
We had to put starchy water into a beaker and then we added iodine. If the test was positive, then the startchy water would turn blue-ish black...

here's what it looked like when we put the iodine in.. (the iodine started out being orange-ish brown)
When we stirred that up, the whole thing turned darker and black and dark blue.
