Summary
The first thing the students must do is determine the density of solids. Students must obtain a regular shaped solid and record its identification number and then with a ruler determine the physical dimensions to the nearest 0.2mm. Then students will determine the mass of the regularly shaped solid to at least the nearest mg (0.001 g). Having the mas and the volume students then must calculate the density of the solid. Students then must obtain a sample of metal pellets and record its identification code number and weigh a sample of the metal of approximately 50 g, but students must record the actual mass of the metal taken to the nearest mg. Students must fill a 100-mL graduated cylinder approximately to the 50-mL mark with water and record the exact volume of water in the cylinder to the precision permitted by the calibration marks of the cylinder. Students must then pour the metal sample into the graduated cylinder and have to make sure that none of the pellets stick to the walls of the cylinder above the water level. Students must stir or shake the cylinder to make sure that no air bubbles have been trapped among the metal pellets and ruin the calculations. Then students will move to the density of pure liquids and have to clean and dry a 25 mL graduated cylinder and weigh it to the nearest mg. Then students have to add distilled water to the cylinder so that the water is above the 20mL mark but, below the 25mL mark and, then determine the temperature of the water. Students then must weigh the cylinder again to the nearest milligram and record the exact volume of water in the cylinder. Then students must calculate the density of the water and compare the measured density of the water with the

Brain Size Lab Summary

Introduction The topic examined in Lab 4 is how Body Mass, Brain Size, and Life History variables, demonstrate the distinctions amongst humans, apes, and other primates. These variables are related because they demonstrate positive correlations in the scatterplots in the Data Analysis worksheet for Lab 4 of Age of First Reproduction (years), Maximum Lifespan (years), and Observed Brain Size (cc) of the species, in relation to an increasing Body Mass (kg). By examining these variables, the Encephalization…
