Abstract In our Berlese Funnel lab we sampled two different types of forest‚ deciduous and coniferous‚ both on our school campus. We set up multiple funnels in our classrooms with heat directly above them. After collecting leaf litter from our designated forest we placed them in a funnels above beakers of alcohol. We let them sit for two nights in a row and while in class checked for different organisms under microscopes. We calculated the different amount of species and how many there were of each

The Marsh funnel is a simple device for measuring viscosity by observing the time it takes a known volume of liquid to flow from a cone through a short tube. It is standardized for use by mud engineers to check the quality of drilling mud. Other cones with different geometries and orifice arrangements are called flow cones‚ but have the same operating principle. A modern plastic Marsh Funnel In use‚ the funnel is held vertically with the end of the tube closed by a finger. The liquid to be

Discussion: First of all‚ rinse all the apparatus that being used in the experiment with hydrochloric acid (HCL) then followed with distilled water (H₂O). Then‚ prepared the saturated calcium hydroxide (Ca (OH) ₂) solution into a filter funnel and filter paper over a second conical flask. Pour 100.00mL of saturated Ca (OH)₂ solution into a beaker and pour the solution through the filter paper by flowing the solution through a glass rod. After that‚ use a thermometer to measure the temperature of
