And the switch went on and - hey presto! - the light bulbs lit up - woo hoo!

Mr Muir explains a simple circuit to us today, as part of our Inquiry into electrical technology.

Success!

Using a philips screwdriver to tighten the screws - great job girls!

Who would like to be an Electrician?

Here is the circuit ready to go. Mr Muir has set the main parts up for us already. Can you see the switch, lamp fitting, battery fitting and the wires?

We are all really excited to be making a circuit. We are learning to put the wires in the correct place, under a screw, under a metal plate. We have to trace the line of the circuit with our finger to figure out if the circuit is complete. If it is not the bulb will not light up when we turn the switch on.

STEM challenge this week!

Can you design a container for holding popcorn at the movies that can stand up and prevents spillage?

1st - we made an origami prototype to hook us in! In groups of 3 we listed the pros and cons of this simple design.
2nd - Then we brainstormed and made a prototype of a container from paper which tried to use the pros and change the cons!
3rd - we made a final design and were able to use sellotape or staples as well as folding to hold it together.

Here are our designs - spot the handles, flat surfaces, curved surfaces
spot the fill holes, the lids, the folded shapes

Today Mrs T brought some popcorn to truly test our designs - Great Mindset everyone this week. It was interesting to see how different your ideas were which showed me how creative you are. There was lots of collaboration and patience displayed. You maintained a positive manner which meant you could state how your design worked and what improvements could be made next time.

Thank you to Karlia for being out photographer.

Teach the Teacher

Teach the Teacher and Room 20 - what will we be learning on Fridays?

The Seniors have Friyays but we have Teach the Teacher! Every week 2 or 3 children will present/ demonstrate/ teach the rest of Room 20 and Mrs T about something. It could be an experiment, a hobby, a sport, cooking, magic, anything that you have a passion or special interest in.

Erin had a wonderful slide presentation on Google docs to explain exactly how to make Frozen play dough. Erin did all her research at home and emailed it to Mrs T so she was ready to go!
Everyone who could brought cups and utensils in case we needed them. Thanks everyone!

Erin did such a great job with all the mixing of ingredients and the children all helped and mixed the dough up so that everyone had a bag of dough to take home!

Next Valentina took the floor with her capable assistant Ruby. Valentina demonstrated her Experiment of Reactions using milk, food colouring, and vinegar.

Valentina was a great speaker and demonstrated carefully and clearly so that we all understood her experiment really well.

The colours mixed together and created new colours then when the vinegar reacted and turned into foam there were lots of oohs and aahs!
