Science Experiment: Gases

Gases made our balloon blow up.

First, we put baking soda in a big bottle.

Then we put vinegar in a cup and poured it in the bottle.

When we put vinegar in it bubbled.

Then we put a balloon on the bottle and it blew up.

The balloon filled with gas.

Science: Solids, Liquids and Gases (Part 2)

We put ice into a cup.
Ice is a solid.
We put the cup into hot water.
The ice cubes melted away.
They became water.
Water is a liquid.
We put the water in a pan on the stove.
The water went away.
It became a gas.
The stove is hot.
Heat made the liquid change to a different state of matter.
We also put water in the freezer and it turned into an ice cube.
Cold changed a liquid to a solid.

Science: Solids, Liquids and Gases (Part 1)

Everything is made of matter.
There are three states of matter.
The three states of matter are: liquid, solid and gas.
Examples of solids: wood, blocks, bricks, stones, LEGOs, tables, trees.
Examples of liquids: water, juice.
Examples of gases: air, tooting, steam.
Salt is a solid but it flows like liquid.

Science: Organizing Things into Categories

Organizing means sorting.
Category means group.
We looked at the cutlery drawer.
It had different things in it.
We organized the cutlery into the right places.
These places are called categories.
We read a book about same and different.
We organized buttons by sorting them.
We sorted them by size.
We sorted them by colour.
We sorted them by number of holes.
We sorted them by leather, metal, plastic, bone, stone.
We played a memory game.
We organized the things on the tray into categories.
Then it was easier to remember the stickers, pencil crayons, crayons and LEGOs.
