Science – Strong Structures

Today we learned about shapes which make structures strong.  This is important SCIENCE and we will be talking about what made it a “Fair Test” tomorrow.  Great teamwork today and we certainly proved that triangles are much stronger than squares – even when they are 3D cubes!

All those bits of pasta and marshmellows!

First we tested how strong the triangle and square shapes were.

Then we built the 3D cube and triangular pyramid.  We tested how strong they were and found that the pyramid stood strong but the cube twisted and collapsed!

 

Then we made them stronger but adding more pasta to create more triangles!

Macroinvertebrates – Our Science Field Trip

On Wednesday we did not meet Ms Frizz and the Magic School Bus, but we did go on a Science Field Trip and we did go in a school bus!

We are going to be using the data we collected to write in our Science journals and work out how healthy our waterways really are.

Here are some photos from our excursion and a big thank you to our parent volunteers who came along as team leaders.  😎 and to Michelle Keppel from Nature Conservancy for organising this fun scientific field trip.

 

WETLANDS AND MACROS

We had so much fun working with Tracy on our wetlands excursion.  The wetland was full and the macroinvertebrates were hiding under logs and other snags or swimming in the sun, just waiting to be scooped up in our big nets.

You did a great job identifying them and proving that our Margaret River and associated waterways are healthy!

Next term, Ian Dowling (who helped one of our groups on the day) will be working with our Year 3 students to create clay tiles using your experience from this excursion, which will make a sculpture for the new school.

Thank you Sally for taking all these photos!  🙂

 

 

Science Experiment at home – Gravity on our Bodies

Don’t forget to bring in your measurements from home so that we can all find out whether gravity actually does change our bodies during the day….?  We’ll be looking at the data from your Science experiment in class tomorrow morning (Tuesday)!  🙂

Also – we will be doing BUDDY READING with T5 (Year 4) tomorrow afternoon, so don’t forget to bring in your favourite book to share!  I wonder what you will choose…?

And – remember to start collecting your recycled materials for your Spacecraft Constructions this week on Friday!  (We hope to see some Mums and Dads there too….9:00 a.m. on Friday.)

Science

Last week we had our first lesson in Science – our Melting Moments unit of work!

Students took home notes about Run, Run, Runny.  Students need to to do some research on which objects change state from solid to liquid or the other way round, and what caused the change.

What is the same and what is different? What caused the changes?

This research can be done over the next few weeks and students need to keep notes and take photos or make drawings of what happens.  They will need to be ready to present to the class what they found out with either a chart, a powerpoint or a talk with some photos and notes during Week 4 of next term.

Perth Zoo Scientists Visit Our Class

This afternoon we were very fortunate to have two scientists from Perth Zoo visit our room to tell us all about how they are working to make sure that endangered frogs and other Australian fauna will survive.  They told us how they work to capture endangered frogs’ eggs and how they grow the tadpoles into little frogs, which they then return to the wild.img_6510-small They also showed us videos and photos to illustrate how small these little frogs actually are, and how small their habitat area is, which makes them very vulnerable.

Tammy showed us the polypipe they use as a speaker to locate exactly where the frog is calling from, to find them.  Everybody learnt how to make the call of the White Bellied Frog.

img_6512-smallThank you for giving up some rest time (before heading out again tonight to track and work with frogs) to come in and talk to us today.

ROOM 6 FEEDBACK FROM THE VISIT FROM THE PERTH ZOO SCIENTISTS

Oliver said:

I think saving the frogs is a very good thing because most of them are extinct.

Sunnee said:

I think it’s a very helpful thing for the frogs because they are saving nature’s lives.

Dlveen said:

I found it interesting how they know which ones are males and which are females.

Kacey said:

I learnt that there are not many frogs left in the wild.  That made me feel really sad.

Ethan said:

The Western Swamp Tortoise used to be all over Australia and now there are only two spots.  It makes me feel quite surprised and sad.

Leroy said:

I think it’s interesting that they have put back around 4 000 endangered creatures.

Josie said:

I never knew there was such a thing as native rats in Australia.  Now I know that those that aren’t native have a tail much longer than their body.

Tori said:

I like how they put the exercise wheel in for the Dibblers so they get fit for the wild.

Gigi said:

I never knew that the way that they told the males and females apart was because they could see the eggs inside the female.

Ruby said:

I never knew that when a frog ate their eyes were pushed back inside their head to swallow.

Oliver also said:

I find it very interesting that you can only find Western Swamp Tortoise in W.A.

Dlveen also said:

I didn’t know that they also look after other endangered creatures as well as frogs.

Leroy also said:

I think it’s cool because they have had the Zoo since 1898 .

Gigi added:

That’s cool because they thought the Dibbler was extinct but they discovered it again.

Mrs Veary said:

I think it’s amazing that Perth Zoo are willing to invest money into a program which breeds endangered species and reintroduces them into the wild.  This is an important contribution to our South West fauna.

Thank you Room 6 for your thoughtful comments and for being such good listeners.  I know quite a few of you are being great CITIZEN SCIENTISTS at the moment and are counting birds using The Aussie Backyard Bird Count app.   🙂

Sometimes Solid

You have worked incredibly well as Junior Scientists this term on your investigations!  🙂

Today we will be recapping our knowledge and our findings and making a table to try to work out what it is that makes certain materials change state from liquid to solid or solid to liquid.

These are the links to activities to further investigate this:

1.  SOLIDS AND LIQUIDS

2. CHANGING STATE (challenge activity)

To answer our SO WHAT QUESTION:

How does the changing of materials from solid to liquid change their shape?

Why does this happen?

How can we use this science fact to help the environment and reduce, reuse and recycle?

here are a couple of videos you can look at:



Melting Moments

melting moments picture (Small)You all worked really well in Science today.  I loved some of your wonderings:

I wonder how long it would take to melt hail? (Oliver)

I wonder how long it would take to freeze jelly?  (Oliver)

I wonder why ice-cream is soft but not like ice in the middle when it’s frozen? (Izzy)

Can hair or meat melt? (Georgie)

What is the hottest something can get when melting? (Sajer)

I wonder how things like butter can melt in a pantry? (Charlotte)

What is the lowest temperature that can melt something? (Robbi)

If you freeze softdrink and melt it halfway, would it be chunky? (Millie)

I wonder what it would look like when plastic melts, and what temperature does it burn at? (Jase)

How long would it take to freeze a banana? (Lazane)

Could lava turn one ice-block into water in two seconds? (Sam)

I wonder why candles melt when you light them? (Grace)

Can a pencil freeze solid?  How long will it take? (Seb)

How does hail freeze? (Kyron)

I wonder if ice-cream could go so solid that you can’t bite into the ice-cream? (West)

Would a banana skin freeze? (Sunny)

I wonder what would happen if you froze a real human being? (Alana)

Don’t forget to start your science observations at home soon and make drawings and notes of what you see.  You need to collect it all and put it together in an interesting way to present to the rest of the class in week 7 to show what you found out about ‘melting’ and things becoming “Run, run, runny!”.

Year 3 Bush Scientists

A few weeks ago the Year 3s went on a Science excursion to Barrett Street Forest Reserve.  As part of our Be a Bush Scientist work, students learnt from Tracey Muir just how to recognise and identify local trees and plants, both on our school oval and in the bush.  We drew and collected bark, leaves and gum nuts of Blue Gums, Karris, Marris and Peppy Trees. 

Thank you to all our very patient and helpful parents who came along on the excursion.  Your help is much appreciated.  🙂

Enjoy this slideshow of the trip. [Students may want to help put some captions into this….?]

Year 3 Bush Scientist Excursion on PhotoPeach

Now we are looking forward to our excursion tomorrow where we will be digging pit traps to see how healthy our bush is and learn about biodiversity.  Wow – can’t wait to get our hands dirty!
