protect a raw egg as it falls to the ground from a height of 8 feet. Your team will receive an egg and a bag of materials. You will be given time to brainstorm how you might construct a protective mechanism for dropping your egg without breaking it. You are only allowed to use the materials in your bag within the time frame allotted. It will be important to work well with your teams in analyzing the materials you are given and predicting which materials will safely protect your egg during its descent

Egg Drop (lab writes) In our science class we did an egg drop experiment. We used the scientific method to answer the question and solve the problem. Our question for this particular lab was “will an egg break or be secured‚ if covered with thick sponges and drop from ten feet above the ground?” our idea was to secure the egg from breaking and we wanted to design something that would provide a lot of cushioning directly on the egg. We came up with many different ideas until we choose

extracellular solution‚ this was deemed the baseline. When we punctured each of the DEM‚ DEL1‚ and DEL2 crayfish muscles‚ we observed a large drop in voltage (refer to Figure 1)‚ therefore indicating that inside the muscle was more negative in relation to the outside solution. The time when the pipette was intramuscular‚ the recording showed a steady reading of the intramuscular voltage potential (Figure 1). When the pipette was removed from the crayfish muscle and was back in the extracellular solution‚ the

Determining the Concentration of a Solution: Beer’s Law Purpose: The purpose of the experiment is to determine the concentration and formula of an unknown cobalt nitrate solution by measuring absorbance. Introduction: A Colorimeter will be used to determine the concentration and formula of an unknown cobalt nitrate solution. The colorimeter sends blue light from the LED light source to pass through the solution and hit a photocell. A solution with a higher concentration will absorb more

I. Research Question What are the effects of different sucrose concentrations on potato stripes which have been submerged in a range of solute sucrose concentrations. II. Background Information Osmosis is one of the four methods of moving particles across membranes along with simple diffusion‚ facilitated diffusion‚ and active transport. Water is able to move in and out of most cells freely. Sometimes the number of water molecules moving in and out is the same and there is no net movement‚ but at

to cool down in an ice bath‚ the benzoic acid crystallizes as it decreases in heat. 4) In the remaining cup‚ heat the sand until the solution is completely dissolved. The sand should be left. 5) Using the cooled solution of benzoic acid crystals‚ filter out the benzoic acid from the table salt using funnels. 6) Calculate the percentage amount for each solution and net amount‚ record data in table.

hypothesis that if a potato is placed in a tube with different sucrose concentrations then the tube with the lowest concentration of sucrose will expand the potato the most because the water will move into the potato to even out the concentration levels of the sucrose/ water ratio inside and outside of the potato was supported by the data. The data shows that the potato submerged in the lowest concentration of the sucrose water solution had the greatest percent change in mass at 15.2% for 0% concentration

Title : Osmosis in Quail’s Eggs Research Question What is the effect of different concentrations of sodium Chloride (NaCl) on the mass of the de-shelled quail’s eggs? Introduction Osmosis is an example of passive transport. Osmosis is defined as the movement of water molecules‚ down its concentration gradient‚ from an area of high water concentration (low solute concentration) to an area of lower water concentration (high solute concentration) through a selectively permeable membrane. Osmosis

with an Egg. Purpose: We are taking a large single cell (the egg) and demonstrating Osmosis. Osmosis is a type of diffusion where the water molecules is the solution that is being moved. Osmosis is the movement of water through a semi-permeable membrane. Diffusion is the movement of molecules from an area of high concentration to an area of lower concentration. Introduction: When trying to create an osmosis reaction‚ it is important to understand Hypotonic and Hypertonic solutions. When
