Today’s Lesson:
Your Investigating Genes project is due tomorrow.
NLT midnight of Thursday, Feb. 11th
This is the daily classroom agenda for Paxton Center School Grade 7 Science. Lesson plans, homework, and other relevant information will be posted here each class.
Due February 11th by midnight
This will form the basis of the following project:
Review requirements
Due February 11th by midnight
Summit View, Wachusett Mountain 6:15am
Carbon dioxide
Needed for photosynthesis
plants obtain from air
Water
Needed for photosynthesis
dissolves and caries nutrients in soil
Nitrogen
necessary for amino acids which make up proteins
proteins control traits
Phosphorus
cell membranes and ATP
ATP is how organisms package, store an access energy for life
Potassium
key in controlling plant metabolism
growth, photosynthesis, etc.
Common fertilizers supply these three nutrients
NPK
“20-27-5 fertilizer” will be 20 percent nitrogen, 27 percent phosphorus, and 5 percent potassium
mixtures vary for different kinds of crops and plants
Plant growth is also affected by having the right amount of:
Light
needed for photosynthesis
plants have evolved to different niches
shade, full sun, etc.
correct conditions very important
water
plants 60% water
dissolves and moves nutrients
temperature
warms encourages germination/growth
cool temps slow development
nutrients
obtained from soil
needed for the chemistry in the plant
