Science Infoblog

To get the best results in this achievement standard you need be clear about how you organise your answers.

All the basic material you need to know about is covered in three short videos, a complete course reduced to 15 mins!

The first video deals with covalent bonding Lewis structures and Lewis diagrams. There is a short quiz at the end of it.

The second video deals with molecular shape and polarity

The third video deals with metallic and ionic bonding. It also examines properties such as malleabilityor ductility and conductivity when molten or in aqueous solution. The solubility of ionic compounds in aqueous solution is also discussed.

good luck

You are going to connect  up the three circuits on page 227 of your workbook. You will then investigate the size of the current in different parts of parallel and series circuits using an ammeter.

Before you begin, a bit of revision watching a really boring video on the properties of series and parallel circuits

And now the challenge:

• get your mobile phones out
• take some pictures or video clips showing what happens during the investigation of the three circuits
• make a movie using windows moviemaker or an animated movie using Animoto. (you need to log on and create an account but you can make 30 sedcond videos for free)

complete the worksheets on pages 227-229

There is a strong financial incentive  for the producer/s of the best video

A group of Y10 students in Shelley’s class delivering information on the formation and eruptions of volcanoes with specific reference to those in New Zealand. It was an outstanding piece of filming, editing and fabulous scientific content (not to mention entertaining!

Art is often chemistry that looks good. Your mission should you chose to accept it is explain changes in the properties of clay as it is allowed to dry, bisc fired then given a final firing and glazing.

Year 9 students had an opportunity to experience the starlab when it visited on Monday
