following objectives: 1. To search for the plants with the same or similar starch content as the Cassava. 2. To determine if the plant starch is durable enough to be compared against mass produced “oxo biodegradable” plastics. C. Significance of the study Discovering a new and different ingredient required for the Bio-plastic will provide an alternative source if ever needed. Doing so may also inspire at the same time‚ an

I. Experiment 1 A. Description of Experiment: Three plastic beakers were used for this experiment. In one‚ a 20 mL of 1% hydrogen peroxide solution was made. In order to get this‚ the stock solution‚ which was 3%‚ was diluted using 10 mL of hydrogen peroxide and 20 mL of water. In the second beaker‚ a ¼ dilution of potato extract was made using 2 mL of potato extract and 6 mL of water. The third plastic beaker contained 8 mL of water. Using the first and second beaker the experimental assay

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)
