Please work through these lessons about sound.

The link below has some great activities. For your science over the next few weeks you can work through some of these at home.

Light

 

Our next topic we are looking at is light. Some of you have completed the Kahoot about this too, well done. Below is a link to a series of lessons for you to complete at home with an adult.

You will find more 'light' resources here: https://www.bbc.co.uk/bitesize/topics/zbssgk7

Monday 8th June is world oceans day- see what you can find out about this. 

How can we protect our oceans? Why are they so important?

Forces and Magnets 

Week seven

 

How do magnets affect each other? 

 

Key words- attract and repel. Can you find out what they mean? 

 

If you have magnets at home, try and answer these questions. 

 

  1. What happens when you bring two magnets together?
  2. Can you feel them pull together or push apart?
  3. Can you feel this with all the magnets?
  4. Is the attraction or repulsion stronger between some of the magnets?

Week six

How strong are the magnets?

 

Look at the statements below. Can you think of a way to find out which magnets are strongest? 

Which of these is true and why? 

Week five

 

What can magnets do? 

 

Try out one or both of these investigations. The questions from week four will help you. 

Week four 

 

What can magnets do? 

 

Think of an item in your home that has a magnet. What is it being used for?

 

Did you know...?

Magnets attract magnetic materials so they can be used to separate metals that are magnetic and those that are not at a recycling plant. A magnet can also be used to pick up heavy objects such as cars at scrap yards, as they are made of magnetic materials.

 

 

Investigate the strength of a magnet by carrying out a number of different activities to answer the following questions:

  1. How many paper clips can your magnet hold in a chain?
  2. How many pieces of paper can your magnet hold on a magnetic surface?
  3. What is the distance between the magnet and the table when a paperclip jumps up?
  4. What is the distance between the magnet and the paper clip when it slides along the table? What is the weight of the heaviest object your magnet can pick up?

Week three

 

This week we are looking at magnetic materials. 

 

 

What does it mean if something is magnetic?

 

  1. Take two minutes to list as many objects in your house that you think might be magnetic.
  2. Next, if you have a magnet on your fridge, use this to test whether these objects are magnetic. The magnet should be attracted to the object if it is magnetic (it will stick to it).
  3. What do you notice about all the objects that are magnetic? What material are they made from?
  4. What happens if you try to put your magnet on a wooden door?
  5. Now try a metal radiator or door handle. What do you notice?
     

 

Note for parents- you could create a magnetic treasure hunt, hiding a range of objects in a box of sand or sawdust and your child could use a magnet to find the lost ‘treasure’. These can be placed in one pile and then the objects could be sorted further by using a sieve.

 

Your child should be able to recognise that the materials found by the magnet are magnetic and made from metal.  The Venn diagram link below will help with sorting them (challenge one) and there is an additional challenge to further their thinking about magnetic materials (challenge three).

 

 

 

Week two

What is making each object move?

Hold a hand up in front of your face and blow on it. You should be able to feel the air pushing.

 

Your challenge this week is to carry out a comparative test to find out more about how windmills work.

 

With an adult, take your windmills outside. Find a place where it will turn (if it isn’t windy then run a little to make it turn).

Is the wind stronger in some places?

Is the wind constant?

Does it matter which way you hold your windmill?

Do your windmills turn the same way?

 

 

Investigation

Equipment- timer, paper and pins for the pinwheel, scissors, straw or stick. (If you don’t have pins then you could try using blu-tack or tape instead).

Explore whether the size of the blades affects how long the windmill keeps turning. Plan how you will make your windmills so that you have four different ones to test. When you have made your windmills you will need to test them.

How are you carrying out your test? How are you recording your results? What do your results tell you? Does the size of the blade affect the time the windmill turns?

 

Air is providing the force to move the windmill, even though we cannot see it.

 

 

Here are two different pinwheels to try- which is best?

Forces and magnets

 

Our new Science topic is forces and magnets.

 

Create a spider diagram in your book to show what you already know about these.

 

Each week I will be adding different challenges relating to forces and magnets.

 

This week:

 

  1. Choose some objects from your house.
  2. Make the objects start to move and stop.
  3. Draw a diagram of the object when it starts to move.
  4. Draw an arrow to show whether the force is a push, pull or twist.
  5. Write a sentence to explain each diagram that you draw.

 

Do you have any wind-up toys? How do these move?

 

Fun facts

A force is needed to make something move, that might be a pull (like a door handle), a push (like a toy car) or a twist (like opening a jar).

 

 

----------------------------------------------------------------------

Adults: 

Demonstrate pushing a toy car along the floor and letting go and then repeat but the second time keep pushing the car with your hand.

Ask: Why did the car stop the first time? Your hand is no longer providing a force to keep it moving but there is something (another force) slowing it down.

Ask: Why does the car keep moving? It continues to move because the force is still acting on the car.

Ask: In both of these examples, what is providing the force? Your hand is providing the force. For the car to move, your hand has to be pushing the car. This is a contact force.

Ask: Can you think of any examples where something starts to move and there is not a contact force? If they suggest examples that involve the air moving the object, explain that the air is in contact with the object. This will be explored further next week. They may also suggest gravity and magnetism. It is not necessary to introduce these concepts at this stage, but just to get them thinking.
