You will be sketching a model building made of toothpicks and marshmallows. The building must be at least two floors (stories) high. It should be able to stand on its own and withstand shaking without toppling over. In this approach, what problem are you trying to solve? What are some of the fixed, chosen, and adjustable design features?

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
