Use all senses as appropriate to identify the component parts of objects and the materials from which they are made.


Characterize materials as solid or liquid, investigate their properties, record observations and explain the choices to others based on evidence (i.e., physical properties).


Experiment with simple methods for separating solids and liquids based on their physical properties.


Observe and compare properties of sand, clay, silt and organic matter. Look for evidence of sand, clay, silt and organic matter as components of soil samples.


Choose, test and use tools to separate soil samples into component parts.


Observe a variety of soil samples and describe in words and pictures the soil properties in terms of color, particle size and shape, texture, and recognizable living and nonliving items.


Observe over time the effect of organisms like earthworms in the formation of soil from dead plants. Discuss the importance of earthworms in soil.


Classify living organisms according to variations in specific physical features (e.g., body coverings, appendages) and describe how those features may provide an advantage for survival in different environments.


Observe organisms closely over a period of time in different habitats such as terrariums, aquariums, lawns and trees. Draw and write about observations.


Observe and explain that plants and animals have basic needs for growth and survival plants need to take in water and need light, and animals need to take in water and food and have a way to dispose of waste.


Describe how animals habitats, including plants, meet their needs for food, water, shelter and an environment in which they can live.


Observe and describe ways in which animals and plants depend on one another for survival.


Use all senses as appropriate to sort objects as being composed of materials that are naturally occurring, human made or a combination of the two.


Choose two animals that build shelters within their habitats. Compare the shelters in terms of the materials and tools they use and the type and purpose of shelter they provide.


Construct a simple shelter for an animal with natural and human-made materials.
