Lab sessions and blog tasks

Lab session 1 - Paper balls

Individually:

• Take two sheets of paper from their notebook. The dimensions of the paper will be measured with a 50 cm (±0.1 cm) rule. 
  
• Make a ball with the paper and measure its diameter with the same rule in the way you consider appropriate, not less than 5 times. 
  
• Repeat the procedure, dividing the second sheet in halves, until 5 or 6 sets of data are obtained. The area of ​​each sheet is calculated by dividing the initial one by 2 (not remeasured). 
  
• Calculate in each case the average diameter with its absolute error and the area with its absolute error and then represent them graphically (in Excel). 
  
• The report must contain an explanation of the measurement method chosen to interpret the results, assessment of the quality of them and evaluation of the method, proposing improvements where needed.

Lab session 1 - The properties of substances

This year, your lab reports will be completed in groups as multi-media blogs. Each group must set up a blog on blogger.com and for each lab session you will be required to update your blog with the necessary information. This information is likely to include:

• Title, lab objective, background information, data stored and presented in a suitable format, conclusions, pictures/videos/diagrams and r.eferences.

The blogs should be open to the public so that your information can be shared globally.
