Grade 1

Physical Sciences

• Materials come in different forms (states) including solids, liquids, and gases. As a basis for understanding this concept students know:
  
  
  • Solids, liquids, and gases have different properties
    
    
  • The properties of substances can change when the substances are mixed, cooled, or heated

Life Sciences

• Plants and animals meet their needs in different ways. As a basis for understanding this concept, students know:
  
  
  • Different plants and animals inhabit different kinds of environments and have external features that help them thrive in different kinds of places
    
    
  • Plants and animals both need to take in water, and animals need to take in food. In addition, plants need light
    
    
  • Animals eat plants or other animals for food and may also use plants (or even other animals) for shelter and nesting
    
    
  • How to infer what animals eat from the shapes of their teeth (e.g. sharp teeth: eats meat; flat teeth: eats plants)
    
    
  • Roots are associated with the intake of water and soil nutrients, green leaves with making food from sunlight

Earth Sciences

• Weather can be observed, measured and described. As a basis for understanding this concept, students know:
  
  
  • How to use simple tools (e.g., thermometer, wind vane) to measure weather conditions and record changes from day to day and over the seasons
    
    
  • The weather changes from day to day, but trends in temperature or of rain (or snow) tend to be predictable during a season
    
    
  • The sun warms the land, air, and water
