Week 18

Growing salt crystals

When you stir salt or sugar into water, it disappears but it hasn't really gone anywhere. It has dissolved - broken down into tiny bits that are mixed into the water.

Some materials can dissolve and then form again as shapes called crystals. 

You will need:

  • salt
  • hot water
  • small heatproof measuring jug
  • teaspoon
  • string
  • pencil

Instructions:

  1. Ask an adult to half fill the jug with very hot water.
  2. Stir in 10 teaspoons of salt.

   3. Keep stirring until all the salt disappears. Keep adding more salt and stirring until there is a bit of salt left at the bottom that won't dissolve.

   4. Tie a short piece of string to the middle of the pencil. Balance the pencil over the jug so that the string dangles down into the water.

   5.  Now leave the jug in a safe place for a few days. Check it every day. You should see the crystals starting to grow on the string.

   6.  When the string is covered in crystals you can take it out and look at them closely.

 

Now try this:

- You could look at your crystals even more closely, using a magnifying glass. Can you see what shape they are?

- Try adding a bit of food colouring to the water.  Can you make coloured crystals?

 

What has happened:

The salt dissolves in the hot water and breaks down into tiny bits. But as the water cools, the bits start to clump together again. Gradually the water evaporates (turns into a gas), leaving the salt behind.  The string gives the crystals a good place to stick to, so they start forming there. 

 

 

Bubble Fun

Blowing bubbles is super fun!

In this lesson, we are going to use observation skills and testing

to discover how to make the best bubbles.

Week 15

The Shrinking Puddle

Liquids can change into gases.

Gases are very spread out and can disappear into the air.

Watch this happen with a puddle.

You will need:

  • some water
  • a bowl / jug
  • an outdoor space
  • a dry, warm, sunny day
  • chalk
  • ruler / measuring tape

 

Instructions for investigation:

  1. Fill bowl / jug with water.
  2. Pour water onto the ground to make a puddle.
  3. Draw around the puddle with the chalk.

  1. Keep checking the puddle every half an hour or so and draw around the puddle  each time.
  2. When the puddle has gone measure the size of each chalk circle. If you do not have a ruler or measuring tape you could use string or wool and compare the different lengths measured. 

 

What has happened?

As the sun and the ground heat the water, it slowly turns into a gas, or 'evaporates'. The gas, called water vapour, escapes into the air. The puddle shrinks from the edges, because more heat can reach there from the surrounding ground.

13-5-20                Animal Groups

There are lots and lots of different animals all over the world.

Each animal has been classified by scientists so it belongs to a group.

Can you remember how we sorted animals into groups at school?

Test your memory by taking part in this lesson.

Discover some facts about amphibians, birds, fish, mammals, minibeasts and reptiles by clicking on the link below. 

3-5-20                                       Parts of a plant

Ask your parents if you can take a plant from the garden. Carefully dissect it.

Can you name the different parts? Do you know what they do?

The powerpoint below might help you.

 Excellent Electricity

Make a list using words / drawings to find all the things in your home that use electricity.

If you could keep only one item which would it be? Why?

 Sounds all around us

Sit quietly for 1 minute (60 seconds). Make a list of everything you can hear. Try this in different places, indoors, outdoors or even in the bath. Who in your family can hear the most sounds? Can you imagine what sounds you could hear in other places e.g. space, rainforest or maybe in a swimming pool.

Click on the robin below to see Maddie Moate and Greg's science videos

which are shown on Youtube at 11am each weekday.

 

Zoom in Zoom Out - Blue Tit

  

Have a look in your garden or out of your window and see if you can see any birds.

Look at the resources below to help you to identify each bird.

Could you count how many different breeds of birds you can see?

You could make a bar chart or check list of birds.

Investigate other objects, how are they made?

Animals and their Habitats

This term our science topic is Animals and their habitats.

Below are some ideas to help you continue your learning at home.

Can you identify each animal?

Is it a fish, an amphibian, a reptile, a bird or a mammal?

What do all the animals have in common?

Look at the picture and group the animals then go to page 2 to see if you are correct.

Fantastic Fruits

Collect a selection of fruits.

Are they all the same? Do you know what they look like inside?   

Look inside - what patterns do you notice?

What countries do the fruits come from?  How did the fruits get to us?
