What affects osmosis in plants
Outline
This investigation is about what affects the rate of osmosis in plant. We will be doing an experiment with different amounts of sugar solutions in seven different beakers filled with the same amount of water. Each beaker will have a stronger solution than the first. We add three potato chips into each beaker and find out what happens to them after a period of time.
Equipment
Seven beakers – used to put the water and chips into
Potato – used to test the affect of osmosis
Core borer – pushed into the potato to get equal sized and shaped pieces
Water – put into the beaker for osmosis to take place
Sugar – put into the beaker to affect osmosis
Ruler – use to measure the chips in case of size difference
Measuring scales – use to measure the amount of sugar
Method
First we got seven beakers and poured water into each one. We then poured different amounts of sugar that were meant to be weighed on the scales and put them into each beaker but there weren’t any so we will have to weigh them next time. We got a potato and used a core borer to get 21 equal shaped potatoes. We should have measured the potatoes with a ruler making sure they were all the same size before putting 3 potatoes into each beaker. We then left it for about 1 hour. We poured out all the potatoes on the table and measured them again and wrote down the changes in size in different amounts of sugar solutions in the results table.
