Magic Milk Experiment #1

Teaches Kids About: Atoms and Molecules

Difficulty Level: Easy

1. Pour the milk into the bowl. Be careful not to move the bowl,

you want the milk as still as possible.

2. Put one drop of each color in different places in the milk.

3. Put just a tiny amount of soap on the end of the cotton swab,

then touch it to one of the colours. WOW!

4. Let the experimenting begin!

5. To clean up, just pour the milk down the drain. (Do not drink it)

Note: Milk is made up of minerals, proteins, and fats. Proteins and

fats are susceptible to changes. When the dish soap is added to

the milk, those molecules run around and try to attach to the fat

molecules in the milk.

Materials:

o Dish bowl

o ½ cup of milk

o Dish soap

o Cotton swab

o Food Colouring, more than one color

Water Fireworks Experiment #2

Teaches Kids About: Atoms and Molecules


1. Fill the tall glass almost to the top with room-temperature

water.

2. Pour 2 tablespoons of oil into the other glass.

3. Add 2 drops of food coloring to the glass with the oil.

4. Stir the oil into the food colouring using a fork.

Stop once you break the food colouring into smaller drops.

5. Pour the oil and colouring mixture into the tall glass.

6. Now watch! The food colouring will slowly sink in the glass, with

each droplet expanding outwards as it falls. Looks like fireworks!

Right?

Note: Food colouring dissolves in water, but not in oil. So when

you pour in your food coloring/oil mixture the oil will float at the

top of the water because it is less dense, and the food coloring

will start to dissolve once they sink through the oil and into the

water.

Materials:

o Water

o Oil

o Food Colouring (Any color of your choosing)

o 16 oz clear glass or mason jar

o Another 16 oz clear glass or mason jar

o A Fork

Tornado in a Bottle Experiment #3

Teaches Kids About: Weather


1. Fill the plastic bottle with water until it reaches around three

quarters full.

2. Add a few drops of dish washing liquid.

3. Sprinkle in a few pinches of glitter (this will make your tornado

easier to see).

4. Put the cap on tightly.

5. Turn the bottle upside down and hold it by the neck. Quickly

spin the bottle in a circular motion for a few seconds, stop and

look inside to see if you can see a mini tornado forming in the

water. You might need to try it a few times before you get it

working properly.

Note: Spinning the bottle in a circular motion creates a water

vortex that looks like a mini tornado. The water is rapidly spinning

around the center of the vortex due to centripetal force (an

inward force directing an object or fluid such as water towards

the center of its circular path). Vortexes found in nature include

tornadoes, hurricanes and waterspouts (a tornado that forms

over water).

Materials:

o Water

o Dish Soap

o Glitter

o Tall Narrow Plastic Bottle

(like a VOS water bottle)

Lightning and Thunderstorm Explained

Colour the picture.

What is a thunderstorm?

A thunderstorm is a storm with lightning and thunder.

It is produced by a cumulonimbus cloud, usually producing

gusty winds, heavy rain and sometimes hail.

What causes a thunderstorm?

The basic ingredients used to make a thunderstorm are

moisture, unstable air and lift. You need moisture to form

clouds and rain. You need unstable air that is relatively warm

and can rise rapidly. Finally, you need lift. This can form from

fronts, sea breezes or mountains.

What is lightning?

Lightning is a bright flash of electricity produced by a

thunderstorm. All thunderstorms produce lightning and are

very dangerous. If you hear the sound of thunder, then you

are in danger from lightning.

What causes lightning?

Lightning is an electric current. Within a thundercloud way up

in the sky, many small bits of ice (frozen raindrops) bump into

each other as they move around in the air. All of those

collisions create an electric charge. After a while, the whole

cloud fills up with electrical charges.
