Hey Everybody!
The first thing we did today was the plant of the day. Today's plant was a moss ball (which is actually made of algae).
Mrs. Stein then stamped our homework that was due. (UP 67-68)
We then got started on our plant pigments lab. It was based on what kind of pigments are found in different plants. We looked at a spinach leaf and a red leaf. We determined the different pigments in the plant by first transferring the green/red from each plant onto a drawn line on this paper called chromatography paper. We then rolled up the paper and put the bottom portion of it into alcohol. We waited about 10-15 min. Once the time was up, we saw how the different colored pigments separated on the paper. This is what our results looked like once the pigments were separated:
We also took some notes on photosynthesis. The main things you have to know are:
- (reactants) 6CO2 + 6H2O = (products) C6H12O6 + 6O2
- Photosynthesis takes place in the chloroplast!!
You have to know this picture!!!
The HW for tomorrow is :
- UP 81-85 OR Cornell notes
- Finish Pigments Lab
- National Parks Research
KELLI will be our next scribe!
