Science- How does sound travel?

How does sound travel? 

As part of Room 8s Science learning we explored how sound travels. In pairs we attached string to a metal object like a spoon. While one person held the ends of the strings on or in their ears, the other person struck the metal object with scissors. WOW!!! We heard some very loud noise in our ears!

How had the sound travelled so loudly to our ears?
Why was it so loud?
Did everyone have the same result?

We discovered that sound travels in waves along the string to our ears!

Maybe you know a lot about sound waves and vibrations and would like to share your knowledge with us?

Learning the Place Value of 3-digit Numbers

Learning the Place Value of 3-digit Numbers 

Our Maths groups got busy with place value blocks to learn what each digit means in a 3-digit number.

After we had made the number that the teacher had written, we made our own numbers out of the ones, tens and hundreds blocks and wrote our number on a whiteboard. We learned that there are rules about how many blocks we could put in each part of the "trend setter house" like no more than 9 could 'live' in each part. If that happened,  ten had to move out to the neighbour's house! We had a lot of fun with the blocks and went on to add on in tens, add and subtract tens. It was so easy to understand!

Matariki GIF making animation

For the last few weeks room 8 has been learning about making animations.
To begin with we looked at the planning on our class site with Whaea Debb.
To start with we went on Google Slides on our iPads. We practiced changing our backgrounds and we practiced using the Shape Tool. We also tried resizing our shapes.
Then we talked about our Topic of Matariki and we decided to make an animation about what we have learned.
Next we made shiny stars, and coloured them using the gradient colours.
Then we copied (duplicated) the slide and made little changes. We then repeated that step about 5 times.
After that we then uploaded them to the website Talltweets, where it turns them in to GIF animations.

What we liked most about making animations was colouring them, making them move, making the shapes, resizing the shapes, and copying them.
What we found most challenging was resizing the shapes because we thought we could use the pincer movement but that didn't work for slides. We had to tap on the shape and drag the corners instead.

For next time we would like to try other animations about different topics.
