2.E.2 The student will demonstrate an understanding of the daily and seasonal weather patterns.
2.E.2A Weather is the combination of sunlight, wind, precipitation (rain, sleet, snow, and hail), and temperature in a particular region at a particular time. Scientists measure and record these conditions to describe the weather and to identify patterns over time. Weather scientists (meteorologists) forecast severe weather so that communities can prepare for and respond to these events.
2.E.2A.1 Analyze and interpret data from observations and measurements to describe local weather conditions (including temperature, wind, and forms of precipitation).
2.E.2A.3 Develop and use models to describe and compare the effects of wind (moving air) on objects.
2.E.2A.4 Obtain and communicate information about severe weather conditions to explain why certain safety precautions are necessary.
P.3 Physical Science: Properties of Solids and Liquids
2.P.3 The student will demonstrate an understanding of the observable properties of solids and liquids and the special properties of magnets.
2.P.3A Solids and liquids are two forms of matter that have distinct observable properties. Some matter can be mixed together and then separated again. Solids and liquids can be changed from one form to another when heat is added or removed.
2.P.3A.1 Analyze and interpret data from observations and measurements to describe the properties used to classify matter as a solid or a liquid.
2.P.3B Magnets are a specific type of solid that can attract and repel certain other kinds of materials, including other magnets. There are some materials that are neither attracted to nor repelled by magnets. Because of their special properties, magnets are used in various ways.
2.P.3B.1 Conduct structured investigations to answer questions about how the poles of magnets attract and repel each other.
2.P.4 The student will demonstrate an understanding of the effects of pushes, pulls, and friction on the motion of objects.
2.P.4A An object that is not moving will only move if it is pushed or pulled. Pushes and pulls can vary in strength and direction and can affect the motion of an object. Gravity is a pull that makes objects fall to the ground. Friction is produced when two objects come in contact with each other and can be reduced if needed.
2.P.4A.1 Analyze and interpret data from observations and measurements to compare the effects of different strengths and directions of pushing and pulling on the motion of an object.
2.P.4A.3 Construct explanations of the relationship between the motion of an object and the pull of gravity using observations and data collected.
2.P.4A.4 Conduct structured investigations to answer questions about the relationship between friction and the motion of objects.
2.P.4A.5 Define problems related to the effects of friction and design possible solutions to reduce the effects on the motion of an object.
L.5 Life Science: Animals and Their Environments
2.L.5 The student will demonstrate an understanding of how the structures of animals help them survive and grow in their environments.
2.L.5A There are many different groups of animals. One way to group animals is by using their physical characteristics. Animals have basic needs that provide for energy, growth, reproduction, and protection. Animals have predictable characteristics at different stages of development.
2.L.5A.1 Obtain and communicate information to classify animals (such as mammals, birds, amphibians, reptiles, fish, or insects) based on their physical characteristics.
2.L.5A.2 Construct explanations for how structures (including structures for seeing, hearing, grasping, protection, locomotion, and obtaining and using resources) of different animals help them survive.
2.L.5B Animals (including humans) require air, water, food, and shelter to survive in environments where these needs can be met. There are distinct environments in the world that support different types of animals. Environments can change slowly or quickly. Animals respond to these changes in different ways.
2.L.5B.1 Obtain and communicate information to describe and compare how animals interact with other animals and plants in the environment.
