OSMOSIS IN POTATO TISSUES Vanessa Tsao‚ Lovette To‚ Wang Yeyun‚ Zhang Shenjia‚ Alicia Mak Class 101‚ Nanyang Girls’ High School‚ 2 Linden Drive‚ Singapore 288683 ABSTRACT In this project‚ the relationship between the concentration of salt solution and the length of the potato strip that was immersed in it was investigated. Five strips of potato of the same length were placed in different Petri dishes that contained water of different salt concentration. They were left for twenty minutes and the length

Rebekah Worley February 21‚ 2012 Mitchell Section 4 Biol 311 Staining and Identifying Unknown Bacteria Introduction: The microbiology lab up to this point has been used to teach the students how to stain and identify bacteria. There are several types of staining through which the bacteria can be identified based on the color and shape. The staining methods used in the lab are Gram Staining‚ Capsule Staining‚ Endospore Staining‚ and Acid Fast staining. One of the most significant method of

Eggs are fried in cooking oil‚ sometimes with a sprinkle of salt. It is common to put a fried egg on top of bibimbap or Kimchi bokkeumbap. Sometimes‚ rice dishes‚ such as bokkeumbap‚ are simply made by applying a fried egg on a top of a bowl of hot rice‚ drizzled with a spoonful of gochujang and sesame oil. Occasionally‚ salt is added to fried eggs‚ and served as Banchan‚ which refers to small dishes of food served along with bap. Fried eggs can be served on toast‚ or in a sandwich‚ with bacon

Investigating the effect of different concentrations of glucose on the percent change in mass of Gummy bears according to their respective colours In this experiment osmosis is the main process taking place. Osmosis is the diffusion of water molecules of a solvent which pass through a semi permeable layer and in most cases are due to a concentration gradient meaning that the water molecules travel from an area of low concentration to one of higher concentration. In this investigation‚ gummy bears

The Bouncy Egg Experiment! Mrs. Murosky December 19‚ 2013 Introduction: GOAL: The goal of this experiment is to get an egg to bounce. WHY IS THIS IMPORTANT? : The results of the egg experiment is important because it shows what the membrane of an egg looks like‚ but allows the experimenter to have fun in the process. LITERATURE: The acids in the vinegar make the shell deteriorate. Eggs contain "calcium carbonate"(this is what makes it hard)‚ and vinegar is an acid. When they both combine

How much salt must be added to a glass of water for an egg to float? Hypothesis: I believe it will take 5 tbsp. of salt to be added to water for an egg to float. My reason is that I think that 5 tbsp. of salt is very heavy and will make the water heavy enough to float the egg. I must make the water heavy enough to float the egg. If the water has enough salt it will float. Materials Used: Eggs – 2 medium sized chicken eggs (2.0oz each) Natural Sea Salt Iodized Salt (table salt)

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

Aim To observe and measure the effect of osmosis on the mass of potato using a starch solution. Introduction In order to measure the effect of osmosis‚ eighteen pieces of potato were cut and placed in six groups‚ each group of three pieces cut to weigh as close as possible to one another. For each potato group‚ a test tube was half filled with a starch solution varying in concentration from 0% (water) to 1%. Hypothesis Through osmosis‚ I hypothesise that as the solution of the starch in

floating egg experiment – How much salt is needed to make an egg float? Aim: To investigate the effects of salt on the density of water (and therefore the ability to float an object in said water) and to find the amount of salt needed to float one regular egg in a glass of water. Research: Internet research shows that adding salt to water increases the density‚ and in turn makes it easier for objects to float. 4-10 teaspoons of salt in 1 glass of water is said to be enough to make one egg float

Egg Baby Project & Baby Think It Over Child Development Ms. Stump You are responsible for your egg baby and must take your baby everywhere you go‚ even to school! There will be a day care center in Room 225 for you to drop off/pick up your baby each day. Please read the requirements and consequences for not following them. This project lasts for four (4) days. You will be given class time to complete the project; you will also be responsible for caring for the baby outside of class. If
