Taking Care of EarthHow Can People Protect the Earth? We can use our resources wisely. That means we must use all resources carefully and not waste them. Do not waste water. Do not litter – throw trash away in a trash can. Do not put bad things in water. Bad things can pollute water. Remember the three R’s: Reduce, Reuse, and Recycle.

WeatherWhen someone asks, “What is the weather today?” you know what they are asking. They are asking what it is like outside.

What is science?Science is the study of the world around us. Scientists study the world around us. When studying things like plants, animals, and rocks, scientists use their senses: Eyes - to see. Nose - to smell. Ears - to hear. Hands - to touch. Mouth - to taste. Scientists study many things – like the things YOU study in 2nd grade: plants, rocks, weather, fossils, solar system, animals. Read more...iWorksheets :3Study Guides :1Vocabulary :1

Hands-on lab skills/Science InquiryPredictions Based on Patterns. Scientists often make predictions based on all the things they already know are true.
