ELECTRIC CIRCUITS

I used my electronic circuits kit to make some circuits. I learned that you need to have a continous (with no breaks) loop for electricity to work. I learned that you need to have CONDUCTORS to make the electricity work. Conductors allow the electric current to run through. Things made of metal are conductors. The whisk made the light bulb come on, but a wooden pencil did not.

SPLITTING A SUNBEAM

Wow! Light is actually made of the colours of the rainbow!

FLOWER DISECTION

Flowers have a lot of very interesting parts.

Here is a diagram of flower parts.

 

I took the flowers apart and looked at the parts with my magnifying glass.

 

PAINTED LADY BUTTERFLIES

I have grown some Painted Lady butterflies. It was amazing watching them grow from tiny caterpillars to big fat caterpillars, then turn into a chrysalis and then into beautiful butterflies.

 

LIQUID LAYERS

Today I did an experiment with different liquids that DO NOT MIX. I used:

OIL
TREACLE
WATER (with blue food colouring)

I learned that the MOLECULES are different sizes in different liquids which is why they do not mix. If the molecules are close together then it is difficult for objects to get through them. This is why liquids and objects that have more spaced out molecules sit on the top of the treacle. Oil always sits on the top of water because it has very spaced out molecules.

BUGINGHAM PALACE BUG HOTEL

Mummy and I made a bug hotel so that small creatures such as woodlice, ladybirds and bees have somewhere dry and warm to live over the winter. This is what we used to make the hotel:

- An old pallet
- An old brick with holes in it
- Bamboo canes - bees love to go inside these
- Pine cones
- Pieces of rotten wood and sticks that we collected from Tiddesley Woods
