Last night, we landed on Mars! The Phoenix robot landed near its North Pole. It will dig into the soil and learn about the water ice.
We have been talking about what can live in space or on other planets. Think about what lives on our own planet, deep underground and in the ocean. In some ways, going to the North Pole of Mars is like going to Antarctica. What could we find there?
Why is it so hard to land on Mars? This video explains:
We also figured out what would happen if too many plants were taken away. William said there would be total chaos! Aidan explained that if the plants were taken away, the animals would have nothing to eat, and then the animals who eat THOSE animals would also have nothing to eat. They would either have to move away to find food somewhere else, or die!
The next game showed us that there has to be a balance. If there are too many predators, they will eat up all the prey! In this game you can control how many plants, rabbits, and foxes there are – our graphs kept coming out looking like roller coasters because the numbers kept changing so much!
