Introduction
Today you will learn to use science tools to observe, measure, test, and analyze. To observe means to look closely and notice. Picture a schoolyard in Texas after a spring rain. A grasshopper from a Texas field sits on a wet rock. Use a hand lens to see its legs and eyes up close. Write what you see in your notebook. A camera, a tablet, or a computer can save a picture or a number so you can look again later. A collecting net can catch the grasshopper gently. A terrarium is a tank for land animals, and an aquarium is a tank for water animals. Both let you watch how a living thing lives.
