Exercise 2 began with measuring the milliliters needed to fill a coffee mug and measuring the liters in a gallon. Then we went to the sink and filled a graduated cylinder with 70 ml of water and then placed a pencil in the water. Our lab partner, Temi had to use both of her hands to push the pencil in the water in order to completely submerge it, because it kept floating upward. After completing these steps, we then calculated and recorded the volume. Once we finished this, we then repeated steps (a-d) to measure and record the rock 's volume.
Water boils to produce steam at 100 C (212 F) b. Water produces gas with sodium metal c. Water and oil separate when combined d. Water dissolves sugar 22. In the experiment, students put brine shrimp in water with different concentration of salt and counted the number. Which of the following changes to the experiment will increase confidence in the validity of the result? a.
The recipe I chose to modify was biscuits and cocoa gravy, a sweet treat that is high in sugar content but very filling. Beginning with the biscuits, I preheat the oven to three hundred and fifty degrees; I poured five cups of self rising flour and a cup of dehydrated rehydrated milk, and half a cup of skim milk into a bowl. Mixing by hand, after I floured my hands to prevent sticking, I added another half cup of skim milk into the bowl. With the biscuits mixed and formed into a ball, I pour olive oil into my cake pan to prevent the biscuits from sticking to the pan. Forcing the dough into small
Those that were not were introduced to our secure procedures (Appendix D) which led to the division process of the experiment. Participants were asked to pull up the chits themselves (Appendix C) and which randomly allocated and indicated them either into the control group or the experimental group. Before the experiment had been conducted, in both procedures of the control group and the experimental group, participants were told about the 24 sets of words (Appendix A/B), and were asked to read out the directions of the study. During the procedure, they were timed individually, one by one outside of the classroom where no distractions could occur which could have affected the results of the study. After the participants were timed, they were sent back together, and were debriefed (Appendix F) about the true aims of the study, and were told that the results were kept confidential and ethical considerations were taken care
I will test the experiment to observe the process of osmosis. The membrane of the egg will all that will be left once the egg has been soaked in vinegar for the significant amount of time. After viewing a video over the experiment and reading on the background and science of it, I will understand why everything happens the way it does. This chemistry experiment has many learning experiences behind it that I will
Our whole group met I could not make it because of SCAD transportation. I agreed to editing and the rest of the group agreed that I would edit the footage that they filmed. To make sugar glass we had to cook. The ingredients we used for this project are 2 cups of distilled water, 1 cup of light corn syrup, 3 1/2 cups of Sugar, and a 1/4 teaspoon of cream of tarter. First we add all ingredients into the metal cooking pot.
investigating the difference in results of using two different types of plant food Ans: identification of Relationship because trying to identify difference between two types of food. h. calculating the mean score on a final exam for a class of 100 students Ans: data reduction because trying to reduce everything and shows meaningful part. i. studying whether exposure to a certain type of chemical results in more frequent cancer diagnoses Ans: Inference because it tries to conclude how certain types of chemical results in more frequent cancer diagnoses. 3. Tell which type of sampling is used (random, cluster, systematic, convenience, and stratified and give clear reasons to support your answer.
The chi square table is shown in the results section as Table 2. A chi square test is an analysis test to see if the results of an experiment match the normal dihybrid ratio (9:3:3:1) that is being looked for. Our experiment was to observe unknown flies and based on their phenotypes, then try and discover the genotypes of the parental generation. We hypothesized that both parents were heterozygous making the ratio
Check the taste after adding 1 tsp and then add another tsp if required. Eggless Chocolate Cupcake Recipe step2 Take cupcake moulds or stainless steel bowls as I showed in the picture. Grease the bowls with olive oil or butter. Fill the batter in each mould. Make sure to fill only 2/3 full as the batter will rise and it should have room for rising in the bowl.
These led her to the idea that maybe the DNA molecule was coiled into a helical shape. Linus Pauling, the US chemist, and author of The nature of the chemical bond, began to think along similar lines. After all, Pauling had already discovered helical motifs in protein structures. Around this time, Francis Crick - with a background in maths and physics, and the younger James Watson, with expertise in the molecular biology of phage (viruses that infect bacteria, then used as a laboratory tool for genetic studies), joined forces at the Cavendish Laboratory in Cambridge, (Picture 2 on the Left) intent on cracking the DNA structure themselves, using a model building
After cutting a block of the fungus, we placed it on the petri dished in the section that was appropriately marked for that specific strain. After the four sections were placed, the lid was placed on the petri dish, and then the dish was with tape to keep close, and wrapped in aluminum foil and placed into the correct bin to sit. After two weeks the petri dishes were ready to be observed. We used a toothpick to scrap lightly the top of the agar in the petri dishes, ensuring we were collecting from one of the dividing lines. With the spores on our toothpicks, we then smeared them onto a slide that was provided to us.
