Topic
Number One |
Potato lab objective.
Collect data and make graph
Reference link http://www.slideshare.net/XAB00DX/osmosis-lab-report
Would like to recruit two lab groups to do a full day run of data collection for Friday. Contact asap.
We may want to alter both the concentration of sugar and salt and change the shape of the potato
