Maths

Well done on all the NRICH challenges you attempted this week- I hope you enjoyed them! 

This week I have an escape room challenge for you to do:

You have been helping your teacher to tidy up the sports equipment after a P.E. lesson. You hear a loud bang and turn around to find that you have been accidentally locked in the school hall!

Solve the clues and puzzles hidden around the room and reveal the keypad code needed to open the door.

The clues could be anywhere so you need to keep your eyes peeled and your mind sharp! Good luck!

Below are the documents you need:

The clue sheet has the questions on them. Be careful- the answer recording sheet has the answers on the second page, so don't look!

I've also included this powerpoint. It has a wide variety of challenges- pick one a day you like the look of to have a go at. 

Literacy

Thank you for all the front covers and articles you have sent in. We need to bulk our magazine out, so here are some page ideas for you!

Every good magazine has the opportunity to write in and get advice on different things from an Agony Aunt or the such. Have a go at writing your own advice page! Here are the resources.:

What else could you include? Here are some ideas:

- A mini game page with word searches, mazes, sudoku, crosswords, that sort of things.

- Fun facts page about your chosen topic

- Top tips page

Topic

We received some fantastic videos this week, so let's have a look!

We have two more types of forces to look at this week:

Water Resistance

Water resistance is the same as air resistance but with objects moving through the water. For example, if you go swimming, you have to push the water out of the way in order to move forward. This is because there is friction between your skin and the water particles. 

Science of Swimming - The level of water resistance increases if your body is completely submerged in the water and therefore it is harder to move. This is why swimmers tend to go towards the surface as much as possible because moving through air resistance allows a better speed of movement than water resistance. 

Penguins and Water Resistance - Penguins are able to glide through the water with little water resistance because they are slim and have bullet-shaped bodies. Although, their feathers do slow them down. To change their direction, they can stick out their flippers which steer them against the water.

Here are some ideas for you to try:

1. Playdough Experiment 

You will need three beakers of water and playdough. Create three different shapes out of the playdough, for example, a ball, a triangle and a square. Put each shape into a different container and and see which ones sink/ float, or take longer than others to float.

2. Aluminium Foil Experiment 

Similar to the Playdough Experiment, you will need three beakers of water, aluminium foil and a handful of small stones. Put a few stones in a ball of foil and fold some stones inside a flat piece of foil and finally, create a small boat out of foil and include the rest of the stones. Which ones sink or float? 

3. Boat Race Challenge 

Create a boat race challenge. Using junk modelling equipment and a tray full of water, make your boats, then time how long it takes each boat to cross the water. 

Friction

Friction is the force which is caused when two surfaces rub against one another. It is a ‘sticking force’, causing objects to slow down or stop as a result.

What is Friction?

Friction is the force resisting the relative motion of solid surfaces and materials sliding against each other.

The amount of friction generated depends on the surface. A rougher surface will cause more friction than something smooth.

Think about pushing or dragging something over the carpet like a box or some furniture.

It would be much easier to push or drag them over a smooth wooden floor as less friction is generated on this surface.

I want you to design your own experiment to investigate something about friction. What could you try to find out? Maybe the different surfaces of flooring in your home? How would you do this? What could you use? I look forward to seeing your ideas!

Keep up the accelerated reader tests and reading at home! It's due to be lovely weather this week (Ha!), so why not send in a picture of you reading outside somewhere fun!

And finally...

- Have you spotted the Sports Day teaser video on the website yet? Keep your eyes peeled, more news coming soon...meanwhile, prepare yourself with some Joe Wicks videos!
