The class of t 7 December

(This is a diagram for a part that is farther down.

Hy!

Today in class we first redid the lab we did last class because it didn't really work.

Than we talked about pigments and how we see colors.

Our next theme was photosynthesis and respiration. While we were talking some of the test tubes popped.
Here is a song about photosynthesis:

This will tell you what photosynthesis.
Celliar Respiration: (not breading)
-happens in cells


-1st stage: (happens in the cytopats)
× takes the foodand breaks it down into smaller molecules (small energy produce
× sends CHO (charbohydrates), proteins, and fats to the cell to be used as energy.
× takin glucos and providing energy.





-2nd: (happens in the mitochondria)
× glokos + oxigen = reaction (no light)
× produces a lot of energy
× C6H12O6 + 6O2 = 6CO2 + 6H2O + energy







After this we did genedicts , because we have flover babies( these are sackes of flower that you have to carry around everywhere like baby) and they nead faces. We were flipping coins so we couldfinde out hove our baby will look.

The homework was to draw the face. http://zagreb.ceesa.net/

Class on Tuesday November 30, 2010

Hi everyone,

During science class on Tuesday we did many things. But first of all remember there is homework that is due on Thursday December 2, 2010 in science class. The homework that is due is the Team Plant Lab. If you lost the sheet go to Moodle under 8 Science 10-11

Make sure that you have the following things in your NOTEBOOK for the Team Plant Lab:

Graph - Make sure its on grid or graph paper (not line paper)

IVs

DVs

UVs & CVs - As many of these as possible

Hypothesis

Paragraph - can be typed or handwritten but must be in your notebook. In here make sure you mention if your hypothesis was supported or negated. Mention at least three errors and why they happened.

State whether everyone put in the same amount of work and effort into the lab (This is separate from the paragraph)

There is also homework due on Friday December 3, 2010. Make sure to do the blog comment by Friday at 4 PM. If you commented twice on this blog you should make sure to also comment on the 7th Grade Blog.

In class we took notes on photosynthesis and started a lab.

Make sure you know these things about photosynthesis:

Photosynthesis is the process of cells taking NRG from the sun to produce food. This takes place in the chloroplasts. CO2 is needed for photosynthesis to happen.

1st stage - Plant captures NRG from sunlight

2nd stage - uses NRG to make food for plant

Some definitions that we learned in class:

Carnivore - eats meat only

Herbivore - eats plants only

Omnivore - eats plants & animals

Scavenger - eats dead stuff

Decomposer - break dead stuff down

Stomata - Opening (pore) on the underside of a plant leaf.

For the leaf stomata lab we started in class we were in groups of two:

Fabi and Davide

Iva and Reza

Terez and Ciprian (Cip)

Viktor and Antonia

Vance and Sophie

Bryce and Giovanna (Gio)

Noam and Valentin (Val)

Calvin and Daniel (Dan)

The main thing you should remember about class on Tuesday is Photosynthesis. Make sure to know about it. If you want to learn more about photosynthesis watch this video.

That was what we covered in Science on November 30, 2010 and the next scribe is...
