Summary: This week in class we learned about Osmosis which means movement of molecules from a higher concentration to a lower concentration. There are three types of Osmosis: Hypotonic, Hypertonic, and Isotonic. Hypertonic is when there is a lower concentration of water for example if this were to happen in a red blood cell it would deflate because all the water would be flowing out of the cell. Hypotonic is when there is a lower concentration inside the cell so all the water outside the cell would go inside inflating it. Isotonic is when there is the same concentration both inside and out the cell meaning it has little to no change since water is flowing both ways.
SP3: Planning and carrying out investigations
This week in class we planned an investigation by figuring out how osmosis works and making a hypothesis on the experiment. We carried out an investigation by weighing naked eggs and soaking them in different liquids and seeing if they were: Isotonic, Hypotonic or Hypertonic.
