Here is an introductory lesson to what Science is. Many young students may not have a good grasp of just what science is so this worksheet give them the idea that there are really 3 areas of Science: Life, Earth and Physical Science. They are given the words that will be used in sentences on the next page. This worksheet would work for 2nd and 3rd graders who can read well. When this worksheet is done, you could have them cut and paste pictures from magazines into the 3 areas described as a collage or have a discussion on what areas of science different objects in the room would go into. Even though planets technically go with physical science, I put them in with the earth science group as that would make more sense to them at this point. I did not give them the names Life Science, Earth Science and Physical Science but you could if you want to.
