Clip Description

Deserts are the driest places on Earth. They receive less than 250 mm of rain in a single year. During the summer months, hot deserts (like the Sahara Desert and the Great Thar Desert) can regularly reach sizzling temperatures of over 50 °C in the day. However, temperatures at night regularly drop as low as – 4 °C. Despite being so dry, most hot deserts are full of life with plants and animals that have adapted to survive without much water.

In this fascinating clip, a remarkable plant called the resurrection plant is a true desert survivor. Despite being dead for over 100 years, it can miraculously come back to life when it finds water. How do you think this plant travels such great distances in its search for water? Watch the clip to find out. 

Quick Whiteboard Challenge

In a region of the Sahara Desert, 240 mm of rainfall fell over the course of a year. All of this rain fell during the months of December, January, February and March.

How much rain might have fallen in each month if all of the amounts were multiples of 10?
