Have you ever noticed that the world is always changing? Scientists observe changes to learn more about the world around them. Things change in many ways. Some things can change in size, color, or shape. Some changes are made by people. Some changes take place in nature. Some changes happen slowly and some changes happen quickly. Sometimes, when a change takes place, things can reverse, or change back to the way they were. Water can freeze into ice, but then it can melt into water again. Other changes cannot be reversed. Once a caterpillar changes into a butterfly, it cannot change back into a caterpillar. Some changes are easy to observe. Other changes must be studied over time. You, too, change in many ways. How have you grown over the past year? What have you learned this week? What changes will you make in your world in the days ahead?
Our year will be filled with growth and change. Watch as our scientists study and observe the seasons of a tree!
