I think the most dirtiest place in the school is the toilet seat because peoples butt touches it and some people accidentally pees on the toilet seat.

Rubbish bin

toilet seat

gym floor

under J block 

Library books 

under table 

food room bench

door handles 

table top 

glass window

bathroom top

inside toilet

outside toilet 

general air

our hands 

drinking fountains

White stuff 

Equipment: Cotton buds, Agar dishes, cellotape

Method:take cotton bud and wipe it firmly on the surface

 Wipe cotton bud across the surface agar jelly carefully

seal the agar plate with cellotype and write the location on the tape

stoe upside down in a dark location



conclusion


Mr stocks handle was the cleanest because after they have science they wash their hands

The rubbish bin because all the dirty stuff like food being eaten and germs grow inside it.

I was suprised by the disgusting fungus growing on the agar dishes

grew the most fungus was the rubbish bin

Grew the most bacteris is the girls door handle

How to make a Home made ginger beer

Aim:


I want to find out how to make ginger beer.


Method:

I need:

water,ginger,Lemon Juice,sugar and yeast.


Combine:
1. 600 ml  water (cold or room temp)- if its too hot you'll cook and kill your yeast.
2.1 tsp yeast
3.Ginger juice
4. 4 tsp sugar- provides food for the yeast and multiply
5. juice of 2 lemons- provides and acidic environment that helps prevent other bacteria from taking over.
6. stir all of this in the jar, cover the jar with some fabric or a paper towel and place jar in a warm area
7.Everyday for the next week feed your yeast with ginger powder and 4 tsp sugar and stir in.
8.After a week, pour the ginger beer through cheese cloth and drink.

Result:
When i smelt the ginger beer it smelt like  raw ginger.
What does it taste like: it taste like spicy ginger putted in your mouth.
When i shook it it made bubbles.

Discussion:

What is yeast: a microscopic fungus consisting of single oval cells that reproduced by budding, and capable of converting sugar into alcohol and carbon dioxide.
What did the yeast do in the ginger beer: I'm about to brew a ginger beer and was wondering if the choice of yeast is as important in a ginger beer, where the ginger dominates the flavour.
What are some other good uses of yeast:  brew beer., make chocolate
what are other bad uses of yeast: bad bacteria

What are some interesting questions that I would like to find out about this experiment: if its going to be yummy or disgusting

Food tech

Question- How does milk become youghurt

Hypothesis-I think put cream and sugar inside the milk and freeze it.

Material-Milk
               yoghurt

method- In a beaker add 150mls of trim milk and two teaspoons of Acidophilus yoghurt. stir to mix. leave out overnight repeat with cream and with blue(full milk)

Observations:Trim,Blue,Cream

Predictions:the cream was thick and looked like yellowish. and the trim milk looks like greenish and the blue milk looks like the original milk. This is what it looks like after freezing it

The cream smells like cheese.

Bacteria reproduced

bacteria fed off the sugar

Trim milk made a thinner yoghurt than blue milk or cream because it has less sugar.

My hypothesis is wrong because we had to put milk and cream together and put in a beaker and after 5 days in the fridge and 2 days out it turned like this. 

Welcome to my very own blog for learning. I look forward to sharing my learning with teachers, my school, my family and friends anywhere.

How the Earth was made

• 4.5 billions ago the sun was surrounded by gas and dust

then the earth melted into a big ball of lava

the heavier material sank to the core 

• 
  
• 
  
• 
  
• the lighter material floated to the surface 
• Every piece of meteorites has a little drop of water inside 
• over 100's of millions of years the ocean was made by all the meteorites hitting the earth  
• The life was made by a chemicals called amino acid
• the amino acid replicate themselves to make protein
• after that the amino acid turn themselves into DNA
• after the DNA was made and now they turn themselves into a bacteria
• bacteria used the poisonous gases to make and release oxygen gas into the early atmosphere
