Egg Osmosis Lab Introduction What is osmosis? Osmosis is a very important part of biology. It is the spontaneous passage of water or other solvents through a semipermeable membrane. A semipermeable membrane is one that blocks the passage of dissolved substances. Osmosis occurs when there is an imbalance of solutes outside of a cell versus inside the cell. A solution that has a higher concentration of solutes than another solution is said to be hypertonic‚ and water molecules tend to diffuse into

This egg drop experiment forced me to think and develop a design that I felt confident with. I developed several models and tested them numerous times‚ but could not settle on one. Eventually‚ I was able to put an addition onto one of my designs which gave me confidence in its ability to protect that precious egg. I will explain why my design worked so well in respect to impulse‚ air resistance‚ and stability. First‚ I will discuss impulse. Impulse is a force acting briefly on a body and producing

1.Discuss the structure of the plasma membrane and explain the process of active and passive transport through the membrane. 2. Explain your observations in detail in terms of concentration gradient‚ diffusion‚ osmosis‚ osmotic pressure‚ passive transport‚ and active transport. Explain what happened to the blood cells at the various levels of concentration. Be sure to refer to the solutions as being hypotonic‚ hypertonic and isotonic. The plasma membranes are made up of proteins that form

experiment was finalized the vinegar solution enlarged the eggs mass. Before the vinegar solution it was 55.1 grams and after the solution it was 67.9 grams. The volume of the egg was also increased. At the beginning it was 50 mL after the solution it was 60 mL; it had a 10 mL difference. It is visible that a hypotonic solution was present. This rejects the hypothesis made. When the egg was placed in 150 mL of vinegar and left intact overnight the egg did sink to the bottom and remain that way‚ however

Math and Science The math teacher can teach students about exponential notation. Once students become proficient in reading and writing numbers in exponential form‚ and in converting numbers between exponential‚ factor‚ and standard form‚ they can apply this knowledge to topics in science. For example‚ they can write the distance between the sun and each planet using scientific notation. For advanced students‚ you can teach them about negative exponents. Then they can explore the half-life of
