Today we will be subtracting fractions.
Start off by tackling the recap, then watch the video below.
Your warm up today is to grab your book and read! Take 10-15 mins to just read your book, either to yourself or out loud to someone else (or the cat!).
Now for your independent writing!
Use the writing from last week to help you, just like we would do at school. Remember to adapt it so that you are now experiencing a storm.
Use your Independent Writing Checklist as you write – this is exactly the same as we use at school! Look on the document for instructions about how to use this.
Your story should be similar to last week’s - remember that you can use the example writing from last week to help you. Try to do this as independently as you can, using the resources here to help.
Don’t forget – this is exactly the process that we use at school for our writing! You should be able to do this on your own J
In this lesson we will be considering the effect of air resistance and aerodynamics.
You will do this by making different paper airplanes! I think you will like this.
The big question is this: WHICH AIRPLANE DESIGN WILL FLY THE FURTHEST IN A STRAIGHT LINE.
You will need
Sheets of paper such as no bigger than A4 .
Outdoor space to throw your planes
A dry not windy day! You may have to do this experiment on a different day if the weather is not suitable.
Which of the panes you made do you predict will go the furthest? Why do you think that?
The only variable we are changing is the plane design. All the planes you test must be made with the same size paper so their mass is the same. They all weigh the same. They must all be tested in the same conditions and you must try to launch them with the same force. I know this isn't easy or strictly scientific. Remember to test each plane a few times and record the result. Throw from the same point each time and measure from the point.
You may want to use the shortest or longest result for each pane or if you are feeling mathematical you may want to find the mean average.
Was your prediction correct?
How far did the best plane go?
Is there a reason that one was the best?
Can you think of any science that could explain the results?
How could you improve your experiment?
Could you do this again but test for accuracy? Distance even in a curved line? Does putting a weight like blu tack on different parts of the plane effect its flight?
Our topic next term will be materials, you learned about liquids, solids and gases in Year 4 so you already know a lot. We will be doing investigations in school and at home to learn more. I can't wait!!
