We are doing a gummy bear lab. Gummy bears come in different sizes, shapes, and colors. Gummy bears are squishy, chewy, and sticky, they are made of sugar which are glucose and glucose are carbohydrate. We predict that during this stage of lab the solute and solvent will go through the stages of hypertonic, hypotonic and isotonic. We get 4 gummy bears and 4 cups filled half way with different types of liquid, such as Salt-Water, Coffee-Creamer, Vinegar, and Soda. We place one gummy bear into each type of liquid. Our question is, how the type of liquid effects the mass and the color of the gummy bears. If we put the gummy bear in different type of liquid, then the mass and the color would change, because of the acidic level. Each day we would
In this lab, we soaked a gummy bear in water for twenty four hours to see the effects osmosis would have on it. When we got our gummy bear we would take its measurements and soak it in water. After twenty four hours we would take it out and record the measurements again and find the percent change. The question that we addressed in this lab was, what would happen if you soaked a gummy bear in water for twenty four hours? I hypothesized that after this time the gummy bear would increase in size.
On Januray 26, 2023, Jelly Bones was found dead in room W1106, a lab in Huntley Highschool’s science wing. The victim was a caucasian female who appeared to be roughly in her mid to late teens with straight, shoulder length blonde hair. When investigator’s arrive on scene it seemed evident that a homicide had occured in the school. The body was discovered by chemistry and foirensic science teacher Mrs. Zuniga, lying unresponsive in the lab. The victim was wearing light blue jeans with a pale gray colored t-shirt.
In this experiment, we observed the relationship between the number of domatia, the number of mites and the size of leaves of water oaks (Quercus nigra L.) and sweet gum (Liquidambar styraciflua). Domatia are small chambers often located on the lower surface of leaves that serve as homes for predaceous mites. In return, the mites protect the plant from herbivory and pathogen attack. This type of interaction between plants and mites is a form of mutualism, more specifically facultative mutualism. Mutualism is an interaction between individuals of different species in which both species benefit.
Unknown Lab Report Unknown # 25 By: Jenna Riordan March 19, 2018 Bio 2843 1. Introduction Microbiology is the study of microorganisms found in all different environments throughout Earth, from the hot thermal vents at the bottom of the ocean to the ice at the top of a mountain.
The data observed and recorded in this lab shows that the concentration of miracle gro’ does affect the growth rate and germination speed of black eyed peas. The data is shown through two graphs and two data tables. The control group in this experiment is the seeds with a 0% concentration of miracle gro’, therefore the seeds with just water. The experimental groups are different concentrations of miracle gro’ including a 10%, 15%, 20%, 25%, and 30% concentration. The variable in this experiment is the amount/concentration of miracle gro’.
The gummy bear in the vinegar solution shrank to 1 cm. The sugar water helped the gummy bear grow close to 2.5 cm and the gummy bear in the plain water didn't change in size.
Rationale The cell membrane, also called the plasma membrane is found in all cells and separates the extracellular side of the cell from the cytosolic side (Cell membrane (plasma membrane), 2023). The purpose of the cell membrane is to communicate with the cell’s external environment, to contain the cell’s contents and to control the transport of molecules in and out of the cell. Diffusion is the passive movement of molecules from an area of high to low concentration.
Urias Fuentes So far, I have learned So far, I have learned that a popsicle stick chain reaction normally comes from potential kinetic energy. When you twist the popsicle sticks together, you are frequently creating potential energy. When you are forming a popsicle chain reaction you need to make sure that each popsicle stick is vertically on top and under the previous stick which creates the tension in the wood of the popsicle stick. When you have your preferred chain length you release, and all the tension and potential energy is released in a chain reaction of kinetic energy.
With inconsistent structures, it is probable that the composition of sugar in chewing gum will contrast between ones that are sugar-based and others that
Does chewing gum really help improve concentration and short term memory? According to many scientific experiments and research that seems to be the case, chewing gum, did in fact improve concentration and short term memory in the test subjects, but why? It couldn 't be some simple coincidence that we could just chalk up to being one of those silly wives tales or just an act of nature that couldn 't be explained. So I decided to do my research and dive into the web, looking at many test and experiments to see what I could find on this topic. Apparently I was not the only one to think this and there had actually been an experiment to test why.
The sugar used in this experiment was created by mixing ten milliliters of starch,glucose, and regular countertop sugar. This was transferred into the joint water bottle tunnel using a funnel. Both ends of the tunnel were sealed shut and each measurements were taken every three minutes and final measurements were taken after 21 minutes. The results were
When we collected liquid from our distillation separation method, liquids #5 and #4 came out clear (without the food coloring). We believe solid #6 is what made our sludge purple. The density of food coloring is the same as water: 1 gram per square millimeter, our density was very close to this it was 0.51g/ cm3 and we could have made mistakes when reading the graduated cylinder.
In this lab we used two processes called Diffusion and Osmosis. Diffusion is the movement of molecules from areas of high concentration to areas of low concentration. Diffusion is a process that requires no energy and involves smaller non-polar molecules. In Figure 1 you can see the molecules spreading throughout the glass from the area of high concentration, so that the areas with low concentration are filled evenly as well. The other process was osmosis.
Osmosis Lab Report Research Question: How does the change in the concentration of a sucrose solution affect the process of osmosis in a potato cell by measuring its mass? Background information: 1 Osmosis is the process by which a liquid passes through a semi-permeable membrane, moving from an area with a high concentration of water to a low concentration of water. There are various factors that affect osmosis such as: concentration, surface area and temperature. The concentration of solutions can affect the rate of osmosis, as there is more difference in the concentration of the solutions, which means osmosis, will take place quicker. Surface area could affect osmosis based on the ease by which molecules can get through the semi-permeable
Next, weigh out 5 grams of sugar and 1 gram of yeast. Once in proportions, add it to test tube A. Thoroughly mix around the sugar, yeast, and tap water. You can do this by shaking the test tube gently. Make sure you do not turn it upside down. Then, cover the top of the test tube with a balloon and gently place it into a 400mL beaker filled up about half way (about 250mL) with water.
