points are properties that can easily be determined and help in identifying a substance. These properties can be found in chemical literature ad reference tables‚ and can be used to distinguish a pure substance from many other pure substances. In this lab you will use the pure substance Paradichlorobenzene and determine its melting an freezing points by warming and cooling a sample of the substance‚ then plotting heating and cooling curves and analyzing them. Data that you collect will represent the

Enzyme Lab Marcus James. December 20‚ 2013 HL Biology 3 Period 1 Purpose and Background The purpose of this lab is to explain how enzymes act as catalysts for biological reactions in different temperatures. This lab relates to enzymes‚ proteins‚ and substrates; that we learned in class. The union of the enzyme and the substrate is called the enzyme-substrate complex. The make-up of an enzyme is proteins and made up of chains and amino acids. Enzymes

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
