The probability that a photon of light will be absorbed by a solution is directly proportional to the concentration of the absorbing molecules, the thickness of the sample and the degree to which the molecules absorbs light. This relationship is called the Beer-Lambert Law and is used in analytical…

Students will study the movement of water and nutrients across a cell membrane and observe osmosis in living tissue. They will then investigate the relationship between surface area and volume as it relates to cells and diffusion. They will also examine the concept of molarity and how it relates to…

Be prepared for spills in your lab. This universal absorbent eliminates the guesswork and is safe for use on all chemicals except hydrofluoric acid. This kit contains enough material to absorb 10 liters of solvent. Complete with instruction sheets and SDS. Kit Contains: 1.1kg Universal Absorbent 1…

Students will use a respiration chamber to measure and record the rate of oxygen consumption (cellular respiration) using germinating seeds versus a non-germinating control sample. Teachers manual and Student Study Guide copymasters are included. There are enough materials provided for 8 lab…
