Week 5

This week, Room 20 and 21 had their school trip to the Auckland Museum.
Room 20's favourite room was the volcano room because it was shaking. Room 20's second favourite was the war memorial because in there were old fashioned objects that we had never seen before.We can't wait until the next school trip.

Week Four

This week Room 20 did lots of exciting things.

The highlight of the week was our Year 3 assembly!

We also did cross country at College Rifles. Room 20 did exceptionally well. We had several people in the top 10 for boys and girls.  Well done to Tegan, Lilly, Alicia, Matthew and Joshua. Sheppard was the winning house with the most points. The teachers looked silly dressed up in fluorescent colours pretending to be from the 1980's!

We have been learning a lot about electrical circuits. We know how to draw a circuit diagram and make it with brainbox.

Year 3 Assembly

We have our assembly next Friday 23rd August! We are going to explain the Scientific Method to the school. Please practice the rap we have been learning in class.

Check it out here... The Scientific Method Rap.

You can also have a play learning more about Galileo (Kate shared about him in class earlier in the week).

Galileo drops ball, virtual experiment.

Have a great weekend!

Static Electricity

Take a look at this video to learn more about static electricity..

Check out this link to roll a can with static electricity... Science Bob.

Try an experiment to test this out...

Static Electricity Experiment

They say opposites attract and that couldn't be truer with these fun static electricity experiments. Find out about positively and negatively charged particles using a few basic items, can you control if they will be attracted or unattracted to each other?

What you'll need:

• 2 inflated balloons with string attached
• Your hair
• Aluminium can
• Woollen fabric 

Instructions:

1. Rub the 2 balloons one by one against the woollen fabric, then try moving the balloons together, do they want to or are they unattracted to each other?
2. Rub 1 of the balloons back and forth on your hair then slowly it pull it away, ask someone nearby what they can see or if there's nobody else around try looking in a mirror.
3. Put the aluminium can on its side on a table, after rubbing the balloon on your hair again hold the balloon close to the can and watch as it rolls towards it, slowly move the balloon away from the can and it will follow.

What's happening?

Rubbing the balloons against the woollen fabric or your hair creates static electricity. This involves negatively charged particles (electrons) jumping to positively charged objects. When you rub the balloons against your hair or the fabric they become negatively charged, they have taken some of the electrons from the hair/fabric and left them positively charged. 

They say opposites attract and that is certainly the case in these experiments, your positively charged hair is attracted to the negatively charged balloon and starts to rise up to meet it. This is similar to the aluminium can which is drawn to the negatively charged balloon as the area near it becomes positively charged, once again opposites attract.

In the first experiment both the balloons were negatively charged after rubbing them against the woollen fabric, because of this they were unattracted to each other.

Hot and Cold Holidays

Hi guys,

We missed Tegan and Ruby as they were both away last week.

Ruby was relaxing in Fiji and getting her hair braided.
