Fifth graders are into their second science standard, energy for humans and other living things!
Our overarching question for this unit is,
We have spent time learning and building food chains and food webs to understand how energy is passed from organism to organism. This week we are delving into photosynthesis and learning more about this fascination process. There are new terms that we are tackling!

DEFINITIONS/TERMS TO KNOW:
basic needs--all living things need the following:
Roots--they absorb water from the soil and carry it to the rest of the plant; also carry nutrients from soil to plant (osmosis)
Stem (Vessels)--water and nutrients move up and down through tubes called vessels; smaller vessels connect stem to leaves; this system helps feed and water all parts of the plant
Leaves--the air plants need moves directly into leaves through tiny openings called stomata; leaves biggest role is to collect sunlight; tubes in leaves that help carry water to the stem are called xylem
Photosynthesis--a process used by plants to convert light energy into chemical energy that can later be released to feed the plant
Chloroplast--food producers of the cell; convert light energy of the sun into sugars which can be used by cells; they take in carbon dioxide, sunlight, and water while giving off oxygen
