Some important points in this experiment is that you need to crush to strawberry very well and when you add the lysis solution not to make bubbles while mixing. It will be extracted out of the test tube using a wooden spool. The results of the experiment will be viewed under a microscope. Introduction This lab report is about how to remove DNA from a strawberry. This study was performed to help teenagers in school learn about the make-up of DNA.
* TTW explain to students that they will need to pay attention o the story so they can know what colors to mix. Procedures * TTW instruct the students to gather around the carpet sitting in their assigned spaces, criss cross apple sauce with hands in their laps, and with their listening eyes and ears. (1 min.) * TTW begin reading the story (10 mins) * TTW then discuss the story with the students afterwards. (5 mins) * TTW ask students to predict what they think they will happens to the colors (2 mins) * TTW break students into groups and have them sit down in their assigned spots (5 mins) * TTW explain to the students that they are going to do a mixing color activity ( 5 mins) * TTW pass out each child a bag of shaving cream, and a sample of two paint colors ( 5 mins).
* Stirring * Temperature * Time * Amount/Type of solute * Amount/Type of solventAsk ch to put hands up and to call out ideas of factors which may influence dissolving and write them on the board. Tell ch that today we are going to focus on TEMPERATURE.Teacher will guide Ch to discuss in talk partners WHY and HOW they think TEMPERATURE may affect sugar from dissolving and then to feed ideas back to teacher and rest of ch.Ch to make predictions about what will happen to the sugars rate of dissolving in each temperature | The teacher will introduce the lesson by discussing with the ch about what they already know about dissolving. * What do the children already know * Any misconceptions * Any new ideas to be discussed * Teacher to make sure that temperature is discussed to obtain any misconceptions about temperature. The teacher will provide ch with post it notes to write down factors which they think may affect dissolving of sugar – make sure temperature is included. Teacher to write these ideas on the board.
Based on this result, what biological molecules are present in the chocolate chip cookie solution? starch What is the relationship between monosaccharides and starches? monosaccharid are the building blocks from which starches are made they are like a monosaccharide Experiment 3: Lipid Test Fill in the table below with the results from the lipids test experiment. Results Lipids Test Solution Initial Color Color with Sudan Solution corn Oil yellow orange-red water clear clear What results would you expect from a sudan test of chicken soup? it would stay clear no change What is the size difference
Why? Experiment 2: Starch Test Fill in the table below with the results from the starch test experiment. Results Starch Test Solution Initial Color Color with Iodine Solution starch solution water Iodine solution is added to a chocolate chip cookie solution. The color changes to purple. Based on this result, what biological molecules are present in the chocolate chip cookie solution?
Purpose and Hypothesis The pupose of this project is to investigate how the presence of seed crystals changes the growth rate of rock candy. My hypothesis is that seeding the string will affect the growth rate of sugar crystals. Materials 1 quart saucepan 1 glass container with a lid 2 cups of regular table sugar 3/4 measuring cup a few drops of food coloring 1/4 teaspoon of flavoring (such as peppermint, lemon, cherry or strawberry extract)optional 1 thin wooden stick or string ruler tape or plastic wrap Experimental procedure 1.measure 3/4 of water and pour it in sauce pan. Heat on medium high until it comes to a boil. 2.pour 2 cups of sugar in sauce pan and stir.the solution should look cloudy at first then i will become clear .then keep stirring for 2 minutes 3.After the sugar is dissolved pour the solution into the jar.
I want to test different kinds of small chocolate candies to find out which kind melts the fastest. I will test these differences: ➢ wrapped vs. unwrapped ➢ rectangle bar vs. kiss shape ➢ big vs. little ➢ plain chocolate vs. chocolate mixed with other ingredients ➢ different kinds of chocolate like milk, and special dark. VARIABLES Independent Variables: The temperature at which the chocolate is melted, the type of chocolate, and how is melt it. Dependent Variables: The dependent variables would be how fast the chocolate melts, and how long it takes. Constants: The shape and size of the chocolate.
Put waxed paper on a cookie sheet. Drop chocolate mixture by spoonfuls onto waxed paper. This will make between 15 and 24 candies, depending on how big you make them. Chill for 3 to 3 1/2 hours in the refrigerator. | | | Substitutions | To avoid soy, select chips without soy lecithin.
Graded Assignment Physical Science Foundations (Sem2) | Nature of Matter | Lessons 5 and 6 Graded Assignment—Physical Science Foundations, Unit 1, Lessons 5 and 6 Lab Report: Viscosity Answer the questions below. When you are finished, submit this assignment to your teacher by the due date for full credit. (3 points) Score 1. Write the goal of the lab or the question you tried to answer. Answer: you will investigate how temperature influences viscosity by methodically racing quantities of honey down a cookie sheet.
Save all Xerox copies, interview notes, Internet printouts, pamphlets, etc. You will need these items to submit with your final paper. 8. As you begin to write your sections of the research paper, you must use MLA format for a research paper and review the paper rubric (to be distributed later) to ensure you are meeting all the criteria both individually and as a group. We will review and practice MLA format in class and you will receive several handouts.
