Title: Potato Osmosis Abstract: In this experiment was designed to study the effect of a concentrated solution applied to white and sweet potatoes. The solution’s impact among the potatoes were to be either hypertonic‚ hypotonic‚ or isotonic. The potatoes were first cut into fries with a fry cutter‚ and then weighed after being cut. The white and sweet potatoes’ weights ranged from .005-.015 grams. A total of 18 sugar solutions are to be made over the course of 3 trials. In each trial‚ 6 different

Making a Potato Powered Light Bulb Materials: A large potato Two pennies Two zinc-plated nails or screws Three pieces of copper wire A very small light bulb or LED light 1) Get a potato and cut it in half. Then make a small slit in each half just big enough to put a penny into. 2) Cut two pieces of copper wire and wrap one around one of the pennies a few times‚ and wrap the other one around the other penny a few times as well. 3) Take a third piece of copper

highlights the fact that we must lend as much attention to all students. In doing so‚ we praise students efforts every chance we get. A way to look at it is that students begin the day with a certain number of chips‚ chips can be earned throughout the day‚ but as they do something incorrect chips are taken away. This process is ok for an individual who has a high self-esteem but the idea is to equate learning disabled children into this equation and they are at a lost before they start the day‚ and it

Observing Osmosis in Potato Cells Planning Purpose: To observe the effect of osmosis on plant cells. Hypothesis: The higher the salt content of the water‚ the lower the mass of the potato. Variables: Independent: the salt percentage of the solution Dependent: the weight of the potato in grams Controlled: the amount of water the length of time between measurements the method of measuring the type of plant cells tested Equipment: (as seen on 2A Human Biology task sheet)

distilled water‚ 0.4% NaCl‚ and 0.9% NaCl would all appear to be inflated and could burst. This is due to the fact that the solution is hypotonic to the potato‚ thus water is entering the cell. Meanwhile‚ the cells in the solutions 5% NaCl and 10% NaCl would have shriveled cells. This is because the solution is hypertonic and water is leaving the potato out into the solution.
