Science Class-Mar 3o-Apr 3

This week, we started by finishing with our science project.  There isn't a lot to discuss about that.  We also had a test.  There isn't a lot to discuss about this, either.  Before we took the test on Thursday, we started a new unit.  We started this on Wednesday.  

The first thing we did when we started the unit was discuss observations:

+we use our senses to observe things

+what we notice happen

+can be qualitative or quantitative

+qualitative- description

+quantitative- numbers

+can be emotions or behaviors

+patterns, changes, trends

+can draw conclusions from it later

+used to answer questions and come up with more

+can be your opinion, but not frequently

+background variables- time, temp., date, ect.

+pictures- draw or from a camera, ect.

+macroscopic verses microscopic observations

Then, we observed cockroaches.  So far, I have observed that :

-they hiss

-can be big or small

-longish body

-brown

-feeler things on head

-shell

-have six legs

-hiss when they are being touched or held

-can be light or dark brown

-has white circles under feet (may have been used to stick)

-have small mouthes

-uses feelers for main sense (I think)

-looked like it was cleaning its foot (doing something with its mouth)

That is all that we did this week.
