Topic 7: Osmosis and Transpiration

 L.I: To learn the science of osmosis and transpiration. This week for science tech we looked into Osmosis and Transpiration. Osmosis is when water moves from the bottom of a plant to the top. Xylem which is a tiny cell in the plant helps the water move upwards. Transpiration is when the sunlight evaporates the water. A thing we learnt during this lesson was photosynthesis. Photosynthesis is a process where the plants creates the food. Its made by carbon dioxide, water, sunlight, sugar or glucose and oxygen. 

Our activity was to find the xylem in a celery. First we pour 150 mls of water in a beaker and put ten drops of food colouring. Next we grab a celery and cut the end of the celery. Then we mix the celery into the food colouring water. After that we put the leaves of the celery in a bag and wait 30 minutes. After 30 minutes we open the bag and start cutitng the middle of the celery. Finally we look for the Xylem and take photos of it.

I found this activty fun because the xylem looks really cool with the food colouring. I also found the facts really interesting.
