Science

Summer 2

This half term, our online Science learning will be about famous scientists with experiments to complete linked to their work. 

Above is a long list of scientists - there were hundreds and thousands to choose from. You might like to find out more to add to the list. Now, the choice is yours as to what you do but here are some ideas. You could find out where they are from, you could focus on the female scientists (Mary Anning is pretty awesome!), you could find out what each of them did for Science or if any of them working on the same area e.g. medicine or electricity. You could find out who made a discovery first and put them in a time line or (my favourite idea) is you could make a Top Trumps card game of Scientists! (I have put a template below if you can use a printer or for ideas of how to lay them out) 

 

Feel free to send your work to year4@matchborough.worcs.sch.uk. We look forward to seeing your research. 

Summer 1

 

TIME TO EXPERIMENT!

 

Escape from the ice!

Find some small plastic figures in your house – they could be lego. You could use any small plastic item but I think people are more fun.

 

Put them in small tubes or ice cube trays and pour in water. You will need about 3 frozen items. Once they have frozen, remove them from the freezer.

 

 

How can you ‘rescue’ your toys? Think of 3 different ways to try and help them escape.

 

 

 

 

 

 

Try out your 3 different methods and time them.

Which method works the quickest?

Can you use any household items to make the ice melt quickly?

Think about what happens when the roads get icy.

 

Were the results what you expected?

Think about what you want to find out next.

Can you think of a different method?

How can you make your test fairer?

Solid --> liquid --> gas

 

Can you think of any items that can change from a solid to a liquid to gas?

Create some flow diagrams of items in your house that change state – you could even take photos of it in the different states.

The Water Cycle

Have a watch of the video below or download the sheet.

 

This is the water cycle.

The water cycle is very important to our life.

 

 

If you can't download the sheet you could always draw your own diagram of the water cycle or try some of the following activities...

 

TIME TO EXPERIMENT

Let’s try to create the water cycle. There are two different ways:

 

EXPERIMENT 1

WITH AN ADULT HELPING:

Get a cup of boiling water, a big metal spoon and an ice cube.

Place the ice cube on the spoon and then put the spoon over the boiling water (not too close)

 

THINK ABOUT IT...

What is happening to the underside of the spoon?

What is this called?
Which part of the water cycle is happening?

 

 

 

 

Draw a diagram of what you’re just completed.

Label it with your observations – what did you see happening?

Try to use the words: evaporation, condensation and precipitation.

EXPERIMENT 2

Get a zip lock plastic bag and draw on the water cycle.

 

You can simply draw a sea, a sun and some clouds or you could add on other parts of the water cycle and label with the correct vocabulary. Have a look at the photos for ideas.

 

Add a little water to the bag to make your sea. You could add food colouring if you have any.

Finally stick the bag to a window that gets lots of sun and watch what happens.

 

 

Changing State

Last half term we found out about Solids, Liquids and Gases.

Try one of the following activities to see if you can remember which 'state' objects are classed as:

 

 

 

 

 

Solids, liquids and gases

Time to experiment

1) Make some ice – you may have ice cubes in the freezer already or even a special machine to make them! If not, find an ice cube tray or a small plastic dish to fill with water. Put in the freezer overnight.

 

2) Place the ice in a sandwich bag. It’s up to you how much.

3) You may want to try this next step with your brothers/ sisters or an adult to make it into a race. Who can make the ice disappear the quickest?

SAFETY: Careful using your hands for a long time on ice – you may want to use gloves.

 

Have a think…

What did the ice turn into?

Which state was it in?

What has it turned into?

Who was quicker? Why?

Was the experiment a fair test?

What could you change next time to make it quicker?

Sky Scraper Ice  Cubes

 

Try making a sky scraper out of ice cubes.

What do you need to do?

Does it work?

How could you improve it?

What happens to the 'state' of the ice cubes?

SAFETY: Careful when handling ice for a prolonged time. Use woolly gloves! 

 

 

Find out more science experiments to try using Explorify!

You will need an email address to sign up but it's free and has lots of ideas for scientific minds!

The Water Cycle

 

Learn a new song that you won't forget! 

Listen to the song below and see if you can hear words ending in the suffix -ation.

  • Evaporation
  • Condensation
  • Precipitation

 

Can you draw a picture of what's happening in the video? 

Can you label it or explain what is happening?
