Science Topic 7 Osmosis and Transpiration

Today for science we learnt about osmosis and transpiration. At first we started with Mrs Sharma was teaching us about what was osmosis and transpiration, then we were watching a video about what happens if you put a celery inside salt water and the outcome is the celery starts to die. Then we watched another video about what happens if we put celery in food colouring and that the experiment are class was about to do. 

The supplies we needed was: 

-Celery

- Water

- Food Colouring

- Cups

- Scissors

When we got are supplies we needed to do theses steps:

- 200 mls of water in a conical flask - Add 10 drops of red food coloring into water - Cut the bottom of the celery - Put celery into water - Stir the water

- Put bag over the celery and tie it so no oxygen can get into the celery - Wait at least 30 minutes before moving the celery

When we did all of that we needed to wait so we learnt more about osmosis and transpiration. After that we untied the bag and took the celery out, it wasn't red that much but we cutted it open then we saw the xylem but I didn't have that much red in mine but it was ok because some of the students had food colouring inside of the xylem and that was really cool. I had lots of fun doing this and thank you to Mrs Sharma for teaching us about osmosis and transpiration.
