Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

conditions; low‚ medium‚ and high density. The effects of different population densities on the survivorship and reproduction of Daphnia are observed over a two-week period within a lab environment. Over the two week period‚ the numbers of parent Daphnia alive and dead are recorded daily‚ along with the amount of offspring produced each day. From the main parameter investigated‚ the net reproductive rate‚ the results of the experiment support that higher densities result in less successful reproduction

Using a simple pendulum to find the acceleration due to gravity/g Task 1 Aim: To find the acceleration due to gravity/g Objective: To find the relationship between the length of simple pendulum and the period oscillation Hypothesis: The longer the length of the simple pendulum‚ the longer the period of oscillation will take. Variables: a) Independent- the length of the pendulum; b) Dependent- the time it takes for 20 oscillations; c) Control - the mass of pendulum. Task 2 References
