Seed Lab I. Purpose/Question: A. What is the variable you are testing? Radish seed vs. Pea seed B. Question 1: How does seed type affect when the seeds germinate? C. Question 2: How does seed type affect the length of the stem? II. Research: List two pieces of information you learned about the variable you are testing below. The radish stem was longer. Both seeds germinated equally fast. III. Hypothesis: Make these an “If-then” statement and do not use pronouns (I‚ we‚ he‚

the weight hanger. 3. Record this as the equilibrium position of the system. 4. Add 5 g to the weight hanger and again record the actual vertical scale reading. 5. Repeat this procedure for 10‚ 15‚ and 20 g added to the weight hanger. 6. To determine the force‚ F‚ needed to displace the spring‚ measure each of the slotted masses‚ individually‚ then convert the sum of the added masses to a weight in dynes (see lab manual for conversion). 7. The extension of the spring‚ x‚ is found

Fermentation Lab: Conclusion & Evaluation of the Effect of Type of Carbohydrate on Amount of CO2 Produced IB Biology/Topic: 3.7 05 February 2013 Question: Which type of carbohydrate‚ glucose‚ sucrose‚ or starch‚ will produce the greatest amount of fermentation over the class period? Why? Hypothesis: If the carbohydrate starch is added to the set up of yeast‚ then it will create the greatest amount of fermentation because starch is a polysaccharides

McLean 1 Creating Acetylene Gas Introduction The purpose of the lab was to determine the ratio of air to acetylene results in complete combustion of acetylene gas. The balanced chemical equation for this experiment was C2H2(g) + O2(g) --> CO2(g)+ H2O(l). Complete combustion is the reaction of an element or compound with oxygen to produce the most common oxides and energy. Complete combustion occurs when the fuel and oxygen combine in exact proportions to completely burn the fuel

Procedure Access the virtual lab and complete the experiments. Part One (Flame Test): 1. Create and complete a data table for Part One of the lab. It should include the name of the element (or unknown) examined and the color of the observed flame: Barium-green Calcium-red Sodium-yellow Rubidium-purple Potassium-blue Lithium-pink 2. Identify each unknown from Part One of the lab and briefly explain why you identified each unknown as you did.: Unknown 1-yellow. I think it is Sodium because

planting them in dry ground due to the risk of the moisture being taken out of the seeds instead of sticking with it to germinate‚ leaving the seed back to its original state. purpose - There are many factors that affect germination‚ however this lab will determine how moisture‚ specifically presoaking seeds will affect germination. To achieve the purpose of the experiment‚ one group of seeds will presoak for a required amount of time‚ for example‚ fifteen minutes to half an hour‚

Butter lab 1 Introduction: While doing this experiment we used 3 terms. We used cream‚ butter‚ and butter milk. Cream is unhomogenized butter. Butter is what we got after the lab was finished. Butter milk is the milk around the butter after it is homogenized and it is thicker than normal milk. If we shake the cream in a jar than will it turn into butter? If I shake the cream than it will turn into butter because it will homogenized. In this lab you will shake a jar of cream and see if will
