A compound is a substance made of 2 or more elements, chemically bonded together. An element is made of only one type of atom.

In robotics we've been learning about mars and how we can build a robot to explore mars, here's a bit I've learnt about mars and how the lander needs to be designed: "Mars can be called the red planet, because of the rusty iron in the ground that makes it look red, Mars has a rocky terrain so the lander will need big wheels so it doesn't get stuck on rocky mountains or even flat terrain with a hot surface so the lander will need to be made out of something that doesn't melt or burn. Mars affects our design because of the rocky terrain, we need it to be bottom heavy so it doesn’t flip over by the extreme rocky terrain the the extreme weather conditions up on mars, it also would need to be bigger than the rocks so it doesn’t topple over and if it flips over we need to have a recovery system to flip up the robot again Our robot also has camera, censors and a claw. The camera for taking photos on mars the censor for detecting moving things and t
