3/4R Why did our boats float, then sink?

Last week, we tested whether our boats floated or sank. All of them floated for at least one minute with no ‘passengers’ (marbles) in them. We then put marbles in the boats to see how many ‘passengers’ they could hold. All boats held between 24 and 97 marbles before they sank, well done!

Testing boats

We now need to think about why they floated and then why they sank, using the knowledge we have learnt so far. What do you think?

WALT: use an online design program to create a poster on why your boat floated.

TIB: good communicators use a range of programs to communicate their message.

WILF:

  • access the Canva website
  • ‘Log in’ using your email address and password (email = firstname.lastname@education.nsw.gov.au)
  • Select ‘Create a design’ and then the ‘Poster’ option
  • Create a poster to explain why your boat floated when it had no marbles in it. Remember to use the scientific concepts we have learnt about this term.
  • When your poster is finished, select ‘Download’ in the top right corner of the screen and then select ‘PDF: standard’
  • Your poster will download. Open it and then save it in our folder in the Collaboration drive.
  • ‘Sign out’ by clicking the face on the top right of the screen

3/4R discover a new webtool!

Today you are going to learn how to use a new webtool.

3/4R Did it float or sink?

Floating and Sinking title image

Last week, we tested whether these objects floated or sank when put in water. Today, you will be looking at your results and thinking about why objects either sink or float.

WALT: analyse collected data and suggest explanations (reasons) for your results.

TIB: it is important to explain and justify our thoughts so others can consider our ideas as important and relevant.

WILF:

  • create a new popplet
  • include a title – Did it float or sink? Include your name under the title.
  • answer the 6 questions using a new popple for each. For example: 1 = 5 of my predictions were correct.
  • save your popplet using the snipping tool
  • ‘save as’ to the collaboration drive

Questions:

  1. How many of your predictions were correct?
  2. Did your predictions get better or stay the same?
  3. Did anything surprise you?
  4. Look at the objects that sank. Describe them. Do they have anything in common with one another?
  5. Look at the objects that floated. Describe them. Do they have anything in common with one another?
  6. Based on your results, why do you think some things float and some sink?

Predicting

WALT: practice our predicting skills on a text.

TIB: good readers know a variety of comprehension strategies to help them understand a text.

WILF: 

  • create a new Popplet
  • include the title of the book
  • organise your predictions as a ‘predict-o-gram’ (words you think will appear in the text, characters, setting, problem, resolution, other) using different Popplet features

3/4R are scientists

Welcome to our new science unit!

We will be learning all about floating and sinking.

Why do some objects float?

Why do others sink?

We will be investigating these questions during the rest of Term 2.

To start, let’s get our brains thinking…

Cyan Magenta Yellow Black

 

WALT:  brainstorm and record what you already know about floating and sinking.

TIB: we can use our ideas to help us understand and learn new things.

WILF:

  • create a new popplet
  • include the title – What I know about floating and sinking.
  • organise your ideas and thoughts using  different popplet features
  • save your popplet using the snipping tool
  • save as to the collaboration drive.

 

WELL DONE!!
