variables are the potato and onions. The dependent variable is the variable whose value is measured to determine the extent of the effect of another variable to it‚ as in an experiment. In osmosis lab‚ the dependent variable is the length of the potato. The controlled variables are the amount of water‚ amount of salt‚ and the size of the potato. If the potato is placed in a higher salt concentration‚ then the potato will decrease its size. We started the lab by cutting the potato core length (44

had two sized potatoes‚ 6g and 10g‚ and placed each in three different dilutions of sucrose at 0.5M‚ 0.1M‚ and 0.05M. We also placed a 6g and 10g potato piece in water to act as a control. Based on the weight percent change over 60 minutes‚ the 6g potato piece had faster water movement than the 10g. This confirms out hypothesis that smaller potato pieces will have a faster rate of water movement. Introduction Osmosis is the diffusion of water across a selectively permeable membrane. Water

The Irish Potato Famine occurred in Ireland in 1845 to 1849‚ when the potato harvest failed. A disease that destroys the edible parts of potato plants known as Late Blight caused the unsuccessful crop. The Irish Potato Famine was the worst famine to occur in Europe in the 19th century. Almost fifty percent of the Irish population had become dependent on potatoes in their diet‚ but the entire population consumed the crop in large quantities‚ especially the rural and the poor. The Potato was very susceptible

The simple‚ sustainable‚ robust device can potentially provide an immediate inexpensive solution to electricity needs in parts of the world lacking electrical infrastructure‚ but we’re hoping that it can work a similar amount of magic for developed nations as well. Researchers at the Hebrew University discovered that the enhanced salt bridge capability of treated potato tubers can generate electricity

Some school districts around the United States are considering putting tracking chips in their students I.d. cards. I have to disagree with this idea for many obvious reasons.

It’s an invasion of privacy and goes against the first Amendment rights. A system to keep track of that many students would be very expensive for schools with low budgets. A
