Biology Prep

Lab . (Skills lab) Use of the microscope practical. Be able to set up and view a prepared slide. Know the parts and types of microscopes we are using.

Lab . A review to find the density of a tissue model- a sponge.

Measure its mass, volume to determine its dry density.

Measure a known volume of water (H2O) and place it in a petri dish. Place the sponge by it and observe what happens. Describe the action- what is it called? Reweigh the wet sponge and find its new mass. Determine with your data you've collected the ratio of the dryweight to the wet weight to determine the percentage and volumetric water weight. What if we started out in the reverse order of this?

Ok let's do it. Allow the wet bit of sponge to sit over night till it is dry. (How could we speed up this drying process?=critical thimking) How could this information be helpful in determining the water weight of some organism?=more critical thimking. Pass Objectives UC
