Y3 Other Natural Disasters Week 6



Watch the following video to find out about tornadoes.

Write down some of the key facts that you learn.


Something you could try at home:


Tornado in a jar

Materials needed:

  • Pint sized jar (small jars seemed to work better)

  • Tsp of washing up liquid

  • Tsp of vinegar

  • Food colouring

Instructions:


  1. Fill a jar with warm water,

  2. Add teaspoon of washing up liquid and a teaspoon of vinegar. You can also add some food colouring. 

  3. Put the lid on very tightly and shake in a circular motion with the jar parallel to the floor for 5-10 seconds. Ta-dah! You have made a tornado in a jar...about an F1 or F2.

Have fun and experiment with different amounts of soap, water temperature and soap types to see what combination produces a better tornado. The above mentioned materials were what worked best for us.  Why it works: Inside the jar, the fluid on the outside starts spinning before the fluid at the centre. When you set the jar down, you see the fluid on the outside slowing down as the fluid on the inside continues to spin. You are seeing the formation of a vortex.  



You could draw a picture of a tornado and write about what is happening.
