This lab requires two separate days for data collection to show the effects of osmosis using dissolved shell eggs and two solutions (Solution A - Hypotonic and Solution B - Hypertonic). The students will find starting and ending mass to calculate percent change in mass and graph their findings. Students will then reflect on which type of solutions each would be classified and what would be considered an Isotonic solution if one were given.
