Hydra...

What did you think of the hydra??? Were you able to identify structures? Why was is green? Did you notice any symbiotic relationships? If so, what were they?

Suspensions, Colloids and Solutions

Someone emailed me tonight looking for clarification on the difference between a colloid and a suspension. This video goes into more depth than you are expected to know, but it is very informative.

For the test you should be able to give examples of each. You should also know the main differences between them. Both are composed of larger molecules than a solution.

Colloids
composed of smaller molecules
usually do not separate on standing
can not be separated by filtration
Example: Fog

Suspensions
composed of larger molecules
separate on standing
can be separated by filtration  
Example: Blood

Separation Challenge!!!

What physical separation techniques did you use to separate the sand, rock, salt, iron mixture? What challenges did you run into today? If you were to do this again, would you do anything differently? What other mixtures could you separate with the techniques that you used today? What solution did you make today?  What was the solute and solvent?

Owl pellets...day 2

What did you find in your owl pellet day? Were you able to identify specific bones? Were you able to determine what organism may have made up this tasty owl meal? What other clues, besides bones, did you use to make this identification?

Rainbow Lab

Great job today!!! Can you tell me what solutions can be made of? What is a solute? What is a solvent? Did you observe a chemical or physical change today?
