Potions - Autumn 1

To finish our topic on solids, liquids and gases, we went onto learn about the water cycle. To understand it better we made our own water cycle IN A BAG.

First we drew a sun, clouds and land on a transparent plastic bag.

Next, we poured a little water into the bag which had some blue food colouring added.

Finally, we sealed the bag and stuck in on the window with tape.

The investigation was to see how the water cycle worked: as the water heated up by the sun, the water would EVAPORATE turning the liquid into a gas (water vapour). As the temperature cooled down in the bag, it would create CONDENSATION forming water droplets on the side of the bag. These water droplets would then drip down as in rain. This is called PRECIPITATION and the cycle would begin again.

Continuing on our solids, liquids and gas topic, we observed the reversible state of liquids in a solidifying state over time. We prepared coloured liquids frozen in a bottle and watched the change of state at different times at room temperature. We noted the results of our observations to show the states of matter of the material.

In our science lesson we learnt how to use a thermometer and how different surfaces have a different temperature. Year 4 used their thermometers to take the temperature of different surfaces measuring hot and cold.

For SMSJ's 60th Birthday celebration, year 4 decided to make rainbow cupcakes for their class and the visitors. Linking the activity with our 'potion' topic, the children coloured the cake mixture in different colours. The cakes were then baked to see a solidified end result. 

Following our science topic on solids, liquids and gases, we investigated how we know gases exist. We experimented to find evidence that 'air' is around us.

For R.E. we have been working on the story of Abraham, the father of a great nation who worshipped and trusted the one and only true God. The class had a task to put Abraham's family tree in the correct order. They then created the tree in their books.

The children then drew and coloured in their own family tree.

Our Science Investigation

Last week we assessed our understanding of solids and liquids. We did an investigation where we explored the properties of some materials such as ; sugar, washing up liquid, a ruler, flour, honey, a sponge and a pen. We wanted to find whether they were a solid or a liquid.

The children also looked at the property of jelly and touched on how the property is reversible.  They talked about how it starts off as a solid, turns into a liquid when added to hot water and when set, turns back into a solid.

Friday Challenge

For our Friday challenges we are set in our house teams, Ruby, Emerald, Amethyst and Diamond.

Ruby team were modelling potion bottles out of clay. The finished products looked fantastic!

The Emerald group made ‘gloop’ and experimented how the mixture turned into a liquid when picked up but set back into a solid in the tray.

The Amethyst team were showing off their sketching skills using different techniques.

Diamond group were sketching a view of their potion room.
