Additionally, it was difficult obtaining a piece of rhubarb that was thin and particularly red, therefore the effect could not be best observed in the cells. Part B: Design your own experiment Parts of this practical were taken and slightly altered from the following link http://www.markedbyteachers.com/gcse/science/investigate-the-effect-of-surface-area-on-osmosis-in-potato-tissue.html Aim: To observe the effect different surface area: volume ratios have on osmosis in potato tissue. Hypothesis: If the potato has a larger surface area: volume ratio, the quicker osmosis will take place and the larger the mass will be at the end of the experiment, therefore the difference in mass of the potatoes from the start of the experiment to the end of the experiment will be larger. Additionally, the potato pieces left in a saltwater solution will decrease in mass, whereas the pieces left in water will increase in mass.
The golf ball would fly down a race track and then set off another mousetrap. Next, the mousetrap would pull a string out of a book which would close the book on top of scissors. Finally, the scissors would cut a string which is holding up a dumbbell and the dumbbell would crack the egg which is sitting in a bowl. This is the project we decided to design in order to crack our egg.
Yes the differences in the salts density will affect how much the salt floats. The dilution with the most salt will be the most dense. This is also buoyancy because the egg is floating in a liquid. I also thi9nk the one with the most volume will float the most. Did you know that saltwater is more dense than fresh water?
The egg also represents the fragile state of the
The egg was a peril white egg in the beginning to a blue splat egg in the end. Starting on Day 0, October 17, was a small, narrow, and white egg with the circumference of 140 mm. On that same day, I let the egg soaked in vinegar for a total of two days. On Day 1, the circumference of the egg was 150mm. The egg was 10mm bigger, squishy, and had a dissolved shell.
This experiment relied heavily on the goldfish, Carassius auratus. The materials needed were a tank, a jar, beaker, tweezers, sponge, fish net, spring water, calculator, a two liter bottle of ice, and oxygen probes. There was another group working, under the same conditions, while using the same tank with a different goldfish. It is important to note, that the only difference between these goldfish were their weight. Since these fishes were already pre-weighted, there was no need to weigh a beaker with water and then subtract the difference if the fish was put in the same beaker and weighed: fish and beaker of water subtracted by the beaker of water.
They really saw how the cell was semi permeable because it allowed the water to leave and enter the cell during different situations. The question that had to be answered on Day 1 was what happened to the egg cell after it was put in vinegar. The hypothesis was proven correct because the egg cell shell was eaten away at by the acidic vinegar since the circumference grew by 13mm. The shell was really soft. If it was in there a little longer that the shell would eventually disappear.
The choosing of a specific egg is random but it was Humphrey’s fate to travel with the hand to the unknown. The hand of their god came down with great force and clamped Humphrey into the palm of his sandpapery hands. Once the god gripped Humphrey firmly, he yanked him into the sky. With this sacrifice made, Humphrey was taken to a warm “fire place” that made him so hot he felt like he was frying. The god picked up Humphrey and he was scared out of his mind.
Our problem was that the cushion was not absorbing the impact like it should have. The egg then met up with the cushion, but instead of soft landing, it cracked.what we should have done was make a styrofoam box, which would be added cushion for the egg. Then line the inside of the egg with Mr.Clean Magic Eraser for padding. Then encase the egg in the Magic Eraser. I liked this project because I had to think very hard.
Additional yarn was arranged in an oval shape in order to hold the egg itself. Three lids were sealed with packaging tape, the left top was cut in a square shape in order to effectively transport the egg in and out of the container. The top lid (untapped lid) was taped on the back edges with Scotch tape at at 45 degree angle.
This essay discusses the making of an apparatus for the egg drop activity while also a lead in about calculations of the final velocity and height of the drop. The aim of this activity is to 1) to demonstrate the understanding of rate of change in momentum and 2) make the apparatus well so the egg doesn’t crack or break. To make sure I was a prepared for this activity and that my egg would survive, I made a list of lightweight things that could possibly be used to make the apparatus structure.
I decided on design 2 for my egg container for its lack of simplicity compared to design 1, and the design seemed more likely to succeed than design 3. During the research process, I found that a bounce to the container would be useful, so I attempted to incorporate that factor into the design of the outer shell by picking a material that would allow for a bounce. I also added cushioning to the egg, as recommended during my research. However, a difficulty I met during the building process was my inability to acquire the right material I wanted for the outer shell of the container. As a side attempt, the rotor I built also didn't work, since the blades were too weak.
The scrambled eggs were placed into the pan. It began to sweat then liquify, as the white and yellow separated and the delicate film of the yolk encased it again. It streamed upward back into the broken shell. The two pieces of shell fit together like a puzzle and sealed shut to keep the liquid in. It was put into the carton and back to be chilled in the fridge.
Where we had to make a shield around the egg to prevent it from cracking. As Adrianne and I did the project together I noticed how uninterested she was in the work. The project was a large part of our final grade and I was determined to get a high score, but apparently, she didn’t care much about what the final grade would be and did very little.
“Whoa! Cool egg!” Mike shouted. CRACK! The egg burst into halves and emerged as tiny baby dragon, covered with golden scales and tufts of
