LS1 2 Modeling Systems in Organisms

Biology and Life Science Safety Guidelines

Project Zero THINKING ROUTINES--see below

HS-LS1-2.    Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.

[Clarification Statement: Emphasis is on functions at the organism system level such
as nutrient uptake, water delivery, and organism movement in response to neural stimuli. An example of an interacting system could be an artery depending on the proper function of elastic tissue and smooth muscle to regulate and deliver the proper amount of blood within the circulatory system.] [Assessment Boundary: Assessment does not include interactions and functions at the molecular or chemical reaction level.]

LAB activities follow safety guidelines linked above and in the activity
​
Lab #1 Plant cells NSF
Lab #2 Seeing cells activity-go to High School (If no microscope/ pond water use this video--Microbehunter  Draw & name the single-cell specimens
​
EXTENSION material for the curious
​

Look closely-and slowly-at the image of a root with root hairs below.  Use your eyes to "zoom in" on the hairs and think about their structure with cells on the outer edge.  How will the structure of the root hair enable water to enter the plant?

Think further about the rest of the plant--and how water (and other nutrients) will reach all parts of the plant
