Ecosystems

2-LS2-1 - Plan and conduct an investigation to determine if plants need sunlight and water to grow
2-LS4-1. Make observations of plants and animals to compare the diversity of life in different habitats
2-LS2-2 - Develop a simple model that mimics the function of an animal in dispersing seeds or pollinating plants*

Earth's Place in the Universe

2-ESS1-1. Use information from several sources to provide evidence that Earth events can occur quickly or slowly.
2-ESS2-2. Develop a model to represent the shapes and kinds of land and bodies of water in an area.
2-ESS2-3. Obtain information to identify where water is found on Earth and that it can be solid or liquid.
2-ESS2-1. Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land.*

Matter and Its Interactions

2-PS1-1. Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.
2-PS1-3. Make observations to construct an evidence-based account of how an object made of a small set of pieces can be disassembled and made into a new object.
2-PS1-4. Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot.
2-PS1-2. Analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended purpose.*
