Product Details

Students will gain experience and understanding using semi-permeable membranes to simulate the absorption of nutrient molecules into cells. Experiments are carried out using starch and glucose to further demonstrate why some of the foods we eat must be chemically broken down before they can be taken up by the small intestine. Results are graphically illustrated by unmistakable color changes which are easy for your students to follow and identify. Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students working in pairs.

Performance Expectations

MS-LS1-2. Develop and use a model to describe the function of a cell as a whole and ways parts of cells contribute to the function.
MS-LS1-7. Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism
HS-LS1-2. Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
