Mexico is the next country in our trip around the World in 50 experiments. Mexico is located in North America and shares a border with the United States. It’s the 14th largest country in the World. Mexico is very hot, with deserts in the north, mountains and canyons in the centre and rainforests in the south.

Mexico is a fascinating country with a long and varied history. It’s full of incredible animals and has many interesting geological features.

Mexico Facts

• Capital city – Mexico City
• Mexico has 31 states and Mexico City which is not part of a state.

• The national symbol of Mexico is the golden eagle.
• Mexico has over 700 species of reptiles!

• The longest river in Mexico is the Rio Grande which starts in Colorado.

Mexico is part of the Ring of Fire, a

The Coriolis Effect refers to how the objects moving on the surface of the Earth appear to follow a curved path due to the rotation of the Earth. It is named after Gaspard Gustave de Coriolis who first described the effect.

The Coriolis Effect influences the movement of wind.

Wind is moving air caused by differences in air pressure. Energy from the sun warms air above land and sea. Warm air is less dense than cold air so it rises creating an area of low pressure. Cooler air moves to where the warm air has risen from creating wind!

Air tries to move from an area of high pressure to an area of low pressure.

Wind mostly blows from one direction on Earth. Warm air rises near the Equator and flows towards the Poles where it cools,

This DIY slingshot is very easy to make and only requires a couple of cardboard tubes, elastic bands and a pencil!

When the pom poms are fired out of the launcher they don’t fall straight to the ground, but instead follow a curved path. This is because there are two forces acting on them. Gravity tries to pull them down, while the forward force from the inner cardboard tube pushes them forward.

Remember to only use soft or very light items with your slingshot. We used table tennis balls and soft pom poms.

How to make a DIY Slingshot

What you need:

Thin cardboard tube. If you don’t have a thin one you can cut a toilet roll in half lengthways and roll it into a smaller tube.

Cardboard tube

2 elastic bands

Pencil

Scissors

DIY Slingshot Instructions

Check one of tubes fits easily inside the other.

Physics is key to understanding the world around us. While some aspects may seem tricky to understand, many fundamental physics concepts can be broken down into simple concepts, some of which can be demonstrated using basic equipment at home.

This list of 5 physics experiments you can try at home is a great starting point for understanding physics and hopefully a source of inspiration for little scientists everywhere!

1. Archimedes and Density

The story behind Archimedes’ discovery of density is that he was asked by the King of Sicily to work out whether a goldsmith had replaced some gold from a crown with silver. Archimedes needed to work out if the goldsmith had cheated without damaging the crown.

The crown weighed the same as the gold the King had given the goldsmith, but gold is more dense than silver so if there was silver in the crown its density would
