shocking science

In year 6 we have been learning about micro-organisms so we decided to do an experiment.The experiment was to see wich places micro-organisms prefer out of : warm ,warm and damp,cold and cold and damp. After a week we went to check to see what happend we discorved that the best place to put bread so mould wouldn't go on it is to put it in the fridge and the worst place to put bread is in a warm damp place because lots of micro-organisms would go on it





This week in science


 Today in science we did a little experiment to see 'which is the best condition for yeast to grow and reproduce?' 

Method:
First of all we put the chosen ingredients in the desinated tubes, then we attached the same size balloons to the top of each test tubes. After this all we could do is wait for the results.

Ingredients:
Test tube 1: Just yeast.
Test tube 2: Yeast and a pinch of sugar.
Test tube 3: Yeast and 10ml of cold/tap water.
Test tube 4: Yeast, pinch of sugar and 10ml of warm water.
Test tube 5: Yeast, pinch of sugar and 10ml of boiling water.
Test tube 6:  Yeast, pinch of sugar and 10ml of cold/tap water.

Fair test:
Same amount of water.
Same amount of yeast.
Same size/type balloons.
Same size test tubes.
Same place.

Conclusion: 
We found out that the micro-organisms need sugar and warm water to survive.
This ment that more carbon dioxide gas bubbles were created which made the balloon on test tube 4 rise and inflate the most.
 

Experiment madness

Last week year 6 Jupiter done a very fun science experiment. We put four types of bread in driffent places. The types of bread were cold cold and damp warm and warm and damp the places were cold in the fridge and warm in the cupboard. The warm and damp got the most mold. The cold and the cold and damp got no mold at all!!!!!so this proves that cold places stop microorganisms getting on your food.down below are the bread altogether and in the places. Also check out shocking science for a driffent point of view and this week in science for are outher experiment.

Time tables


Today in year6 we have been looking at reading time tables in maths
Firstly we drew our line to count on,next we wrote our starting and finishing times and then counted on to work out the time difference
