Netbook Reflection 2013

It has been an awesome idea having and using netbooks in the classroom. Learning has been alot more easier because I am able to do research and find it easier to search for information on the Internet when needed, and play interactive maths games too. I am able to share my work on my blog, use gedit, the webcam, ceate spreadsheets and graphs. Teachers can comment on our work immediately. 

The down side to having a netbook is that sometimes the Internet is slow or not working. Its sometimes takes to long  to load and the tech person only comes once a week.

The interesting thing about netbooks is that I can go on online games, music, webcam, youtube and do our homework.

Netbook is a fantastic tool but some people mis using it.

Inflated Balloon

Question: 
Can a balloon inflate when heated.
Hypothesis:
I think that the balloon will inflate  when heated.
Equipment:
A Bowl
A Balloon
Ice Cubes
Hot Water
An empty Soda bottle
Method:
1. Place an empty soda bottle in a bowl of ice cubes.
2. After about 10 minutes take the bottle out.
3. Slip a deflated balloon on to the mouth of the bottle.
4. Place the bottle in a bowl of hot water and watch the results.

Observation:
When the bottle was placed in the cold water the balloon did not inflate but when we put it in the hot water the balloon inflated.
Result:
The balloon inflates once the bottle gets hot 
Explanation:
The balloon inflated when the bottle was placed in hot water because the warm air expands. This caused an increase in pressure in the bottle which inflated the balloon.
