Cycle Of A Fruit Tree

 

Yearly cycle of fruit trees at Hornby High School.

Apple Tree

Summer

In the Summer the fruit seeds are fully grown so the apple tree is now ready to be picked.
The apple tree when fully grown is pretty big and has a lot of apples on it.
The apples tasted a little bit dry and they weren't that juicy.
The felt like what a normal apple felt like but they were really small.
The apple smelt like nothing













The tree was really big and has a lot of apples on it. The tree has a lot of really green leaves.
Sometimes the apples are small but there were some pretty big apples too.

I think next year around this time that they will be a bit bigger then they were this year because it wasn't as sunny as normal so I think they will be bigger and juicier.

Next season there will be no leave no fruit and it will only look like brown dark branches.
Next season will be Autumn.

Hands On Fire 2017


Aim: We are finding out what its like to put your hands on fire safely in a lab.

Equipment:

  • Water
  • Gas Hose
  • Box
  • Detergent
  • Lighter
  • Safety Glasses
Method
  1. Put your safety glasses on your eyes
  2. Roll up any long sleeves to make sure its past your elbows
  3. Tie up all of your hair and tuck into your shirt
  4. Wet your hands up to your elbows and make sure its all covered with water
  5. Scoop up a handful of bubbles using the gas hose and detergent in a bucket/box
  6. Make sure your hands are straight out in front of you and no where near your face
  7. Get someone to light the bubbles at the bottom of your hands with a lighter
  8. To make the fire stop you move your hands out so it looks like you're a mime
Results: So last year in 2016 I didn't it because I was to scared but this time I stepped up my game and even went first. The fire did not do anything to my hands it only burnt the gas. It made my hands smell like gas but you can easily wash it off with a bit of soap and water. It looks pretty scary but if you ever get the chance to do this experiment you should DO IT. You will love it



























Discussion:
This was pretty safe and did not burn at all but to make it safer is to much sure there is no body around you so you have room to stop the fire.
The fire did not burn our hands because it takes a pretty long time to burn through water which was protecting us but the reason why it burnt the bubbles was because of the gas.
I really enjoyed this experiment because it was something out of my comfort zone and it has a really cool result. I would love to do this again
