This will aid in cushioning the fall and weighting the bottom of the cone. 6) Place the box containing the egg into the cone and tape it into place. 7) Your egg cone carton is now ready to be dropped. Make sure that you drop the cone carton it with the pointy end down. Results: After an exhaustive research period, we came to the conclusion that our egg cone carton did not cushion the egg enough from a side impact.
Osmosis/Egg Lab By: Nicole Dressen Problem to Solve: How the mass of an egg changes in different substances. Information Collected: A. Hypotonic: a substance with lower concentration when compared to another substance. B. Isotonic: when the concentration of two substances is the same. C. Hypertonic: a substance with more concentration when compared to another substance. Hypothesis: I think the mass of the egg that is in the water will stay the same but the mass of the egg that is in the sugar will increase mass.
Make the new dilution series. Remember to start with salt concentration where the egg first floated. (If you don't have enough solution from the original serial dilution, make some more by starting from the stock solution.) 8. As before, test the egg in each cup, starting with the lowest salt concentration.
The motion of these components can be described as d=vt for constant horizontal motion, and d=1/2at² + Vit. The initial velocity with no angle will be found first, and then will be used to find the distance at which we place the bin. Apparatus: You will need: -Projectile launcher -Plumb Bob -Metric Tape Measure -Carbon Paper -White Paper Setup: * Part I * Part II Part I: Determine Muzzle velocity 1. Firmly attach the Launcher Base to a table by using a C-clamp, with the “launch point” (marked on the side with a circle and a cross) hanging over the edge. Make sure the launch range is clear of any obstructions.
There have been accidental children poisoning incidents, which led to the government stepping in. Tide Pods has since decided to put a double latch on the lids to make them more kid proof. This year alone 2012, there were more than 250 pod poisoning accidents reported within the United States. (LaCapria, 2012). Tide Pods (P&G) are working with the American Cleaning Institute to educate and promote the safe handling, use, and disposal of all laundry detergents, and to remind everyone that cleaning products must be kept out the reach of children.
Eggsellent Lab Analysis Questions 1. Draw and label two pictures - Initial and Final - showing the movement of food coloring molecules. You must use all of the following words: high concentration, low concentration, diffusion, and cell membrane 1. Draw the egg after it has been in the food coloring for 24 hours. Explain what might have occurred (be sure to explain what conditions had to exist both inside and outside the egg)using all of the following terms: diffusion, semi-permeable membrane, high concentration, low concentration.
The solution was then drained into an Erlenmeyer flask and I recorded the weight of the flask before (W1) and after the solution (W2) and then subtract the weight of the flask with the solution from the weight of the flask alone in order to find the absolute mass of the solution (W3). I repeated these steps 2 times. In order to find the density (D) of the solution I took the mass of the solution (∆W) and divided it by volume of the solution in the buret. I then averaged the two densities and found that the average density for the egg to float is 1.05g/mL. | 1st | 2nd | | Buret volume: 24mL | Buret volume: 24.1mL | W2 | 141.87g | 141.83g | W1 | 115.18g | 116.15g | ∆W = W2 – W1 | 25.06g | 25.37g | D = ∆W/buret volume | 1.04g/mL | 1.06g/mL | Average Density = 1.04 + 1.06 / 2 = 1.05 | I repeated the same process for the Mohr pipet as I did for the Buret.
BUG BUILDING LAB - You and your partners will begin the "Bug Building" Lab on p. 76-77 Imagine that you are a designer for a toy company that makes toy alien bugs. The president of Bug Builders, Inc., wants new versions of the wildly popular Space Bugs, but he wants to use the bug parts that are already in the warehouse. It’s your job to come up with a new bug design. You have studied how traits are passed from one generation to another. You will use this knowledge to come up with new combinations of traits and assemble bug parts in new ways.
The treatment is simply to place the baby in an incubator with fluorescent light shining on them. The bilirubin breaks down into a form that can be easily excreted when exposed to light, and the colour fades within a couple of days. It is important that this is done because bilirubin is poisonous. If the concentration of bilirubin in the blood gets too high, it can cause permanent brain damage. A bilirubin level of less than 12 ml per dl of blood in the first few weeks of life is generally considered normal for a healthy, full-term baby.
We also collected an accurate amount of acidified water, used to start the reaction. Everything before that point was done with accuracy so we believed it would be a successful experiment, however, we encountered a small problem while swirling the reactants in the”R” tube. The directions stated to swirl untill the solution is in room temperature and we followed this rule but other groups swirled until they saw the reaction getting to a pale yellow. We put the solution over the bunsen burner while it was still pretty brownish in color. For our second experiment, we did not repeat this possible mistake.
