The skills for the year

  • 1Ask questions about natural phenomena and conduct simple investigations
  • 2Plan and carry out observational and hands-on science investigations
  • 3Describe and classify materials by observable properties (texture, color, size, flexibility)
  • 4Investigate how materials can be changed by heating or cooling
  • 5Construct simple arguments about which materials are best for a purpose based on their properties
  • 6Understand and model the life cycle of plants and animals, including birth, growth, reproduction, and death
  • 7Compare the diversity of life in different habitats and discuss animal and plant adaptations
  • 8Describe relationships between plants and animals in a habitat
  • 9Explore how wind and water can change the shape of land
  • 10Communicate solutions to reduce the impact of humans on Earth’s land, water, air, and living things
  • 11Record, analyze, and describe weather data using simple tools (thermometer, rain gauge, wind vane)
  • 12Recognize and describe patterns in daily and seasonal weather changes
  • 13Identify daily and seasonal patterns of sunlight and temperature
  • 14Observe and predict changes in the sky, such as movement of Sun and Moon
  • 15Analyze maps and models to show Earth's features and patterns
  • 16Engage in scientific discussions using evidence from investigations
