Potato experiment. Set up a series of boiling tubes with each of these solutions. Updated november 17 2017. In this activity we are going to explore osmosis by looking at a dataset produced with a classic classroom experiment. Salt sugar and pure water.
Prepare a blank results table before you begin. Take the battery out of the clock if there is one. Next cut a slit in the potato and insert the copper wire end with a penny or with the alligator clips into that slit. Do this for both potatoes.
Use a different piece of wire for each penny. You should allow about two to three hours for the potatoes to soak in the water. This experiment helps students to differentiate between different degrees of concentration. The potato and hydrogen peroxide experiment is a pretty simple way to study the effect of the enzyme catalase on hydrogen peroxide h2o2 catalase is an enzyme present in almost all living organisms.
Next insert the thick copper wire into one slit and the nail into the other slit. Videos you watch may be added to. Make sure when weighing the potato cylinders that their. This is because it is essential to the cell to protect the against oxidative stress due to h2o2 which is produced in small quantities during the normal metabolic activity of the body.
You want there to me as much of the raw potato exposed as possible. Cut the other end. Make sure you slice the potato down the middle lengthwise. Stick the pennies in the slits you cut into the potato halves.
Wrap some copper wire around each penny a few times. First you need two raw potatoes two short lengths of copper wire two galvanized nails three alligator clips and a small single battery lcd display digital clock. Feel the texture of newly cut potatoes slices fill both beaker with 100 ml water each precisely with the help of cylinder add salt to one of the beaker and stir to dilute set timer to an hour and simultaneously place 2 potatoes slices in the beaker and start the timer leave last potato in air wait. First make two slits about 1 deep on each end of each potato.
In this experiment you power a clock using potatoes as electrochemical cells that convert chemical energy into electrical energy. Method prepare a range of sucrose solutions eg 0 20 40 and 100. Cut the potato in half then cut a small slit into each half large enough to slide a penny inside. Science experiments on the osmosis of a potato potatoes in saltwater.
Steps to be followed to build a potato battery first strip one of the ends of one copper wire and if you have the penny available then fit the penny into the. The 0 sucrose solution will act as the control in the.
