xxx1 xxxxxx Ms. xxxx Biology 20 November 2013 Osmosis Lab Problem: What’s the order of the concentration for each solution and how does it affect the movement of water? Hypothesis: Experimenter thinks the order of the solutions according to their concentration is D‚A‚E‚C‚B‚ from smallest. And the water will pass through semipermeable tubing bag from low to high concentration to thin the concentration inside the bag. Osmosis is a diffusion of water particles and is one of the passive transport

PsychSim 5: HUNGER AND THE FATRAT Date: 1/27/15 This activity provides a simulated experiment on weight regulation in rats. The Hypothalamus • What are the two techniques used to study hypothalamic dysfunction? How do they differ? The two techniques used to study hypothalamic dysfunction are stimulation and destruction. To simulate the hypothalamus a small wire probe is inserted into the hypothalamus and a weak but constant current is passed through its insulated tip. Generally‚ simulation makes

is divided into several well-defined sections. Each section must be present in a complete report. To earn an outcome point for the laboratory report‚ a student must submit a formal lab report that earns a score of at least 90/100. Each error (factual‚ grammatical‚ typographical‚ spelling) results in a deduction of 5/100. Several opportunities will be offered through the second half of the semester for students to submit a successful report. Sub-par reports may not be resubmitted for regrading. The

Flame Lab Objective: How an electron absorbs energy and re-emits it as light and why different elements have different spectra. Also to learn how to use flame tests to determine the identity of unknown mixtures. Hypothesis: We know that certain compounds will burn certain flame colors because they emit different wave lengths. Introduction: Neils Bohr made the “Bohr’s Model” in 1922‚ he found that electron travel in specified fields – which‚ when excited‚ will jump to different rings
