After we test it, we find the egg holder is too weak to save the egg. So in the second day lab, we do the adjustments for the new contraption. We use the tapes to reduce the weight of the contraption, and we find the relationship between the dependent variable impulse and the independent variable weight is more weight has more impulse when the contraption hit the ground. We add the support around the egg holder, and we also add a cross under the egg holder to reduce the impulse. We improve the egg holder to a diamond shape container, and the new egg holder perfectly protect the egg from any directions.
My research paper is about Bouncing Eggs. An egg is hard, but if the egg drops it will break. A bouncing egg will bounce, and not break. The egg has certain minerals in the eggshell to make it hard. The vinegar removes these minerals, and the shell becomes soft, allowing the egg to bounce without breaking the shell.
Also, I was aware the cotton stuffing would move more than the paper towel, which would result in a in the egg receiving the shock which would cause the egg to crack. Once my two designs were desirably built it was time to test it. I decided to drop the egg on concrete because being dropped on a soft surface such as grass could have an impact on the success of the eggs. I tested each egg individually; I held the first design (the unsuccessful one) in front of me and dropped the egg. The egg broke due to the cotton stuffing moving around and not being able to absorb the shock.
Write these concentrations down in your lab notebook. 4. Now, starting with cup 5 and working your way up, test the egg in each solution to see if it will float. Use a soup spoon to lift the egg in and out of the cups. 5.
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.
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.
These peroxisomes produce hydrogen peroxide which is very toxic and if Plankton gets in contact with it, it may harm him. Along with the Peroxisome traps SpongeBob has told his nucleus room operators to make as many enzymes as possible that help protect the room by breaking down anything that is trying to break inside. Again Plankton stands up from his chair, this time more dramatically,”Ah ha I figured it out again. I am so smart that not even SpongeBob can stop me this time from finally stealing the krabby patty formula. I am going to get inside the nucleus room through the nuclear pores that allow the mRNA and other small proteins to travel out in and out of the nucleus.” This time equipped with a fully fledged plan he leaves the room with confidence that he is going to steal the krabby
Minimise exposure to nauseating smells, such as cooking or chemical odours (glue/solvents). Change of work pattern where appropriate to avoid long periods of sitting or standing. Minimise risks to infection i.e. rubella, chicken pox by ensuring all children in contact are immunised or not in school if has an infectious condition eg. chickenpox.
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.
The dialysis tubing was one I especially monitored, checking every hour with recordings. After this observation, the raw egg was observed while placed within the jar, followed by the kayo syrup with the dialysis bag. With this I noted that osmosis caused the syrup in the dialysis bag to somehow seep out into the water, then allowing water too within the bag until a point of equilibrium was reached. Concerning the raw egg and vinegar, I noted that bubbles were formed leading me to believe that another compound or element from the binegar was the cause, along with the possible explanation of the egg shells disappearance. The egg also expanded in size with the vinegar, leaving me
