Grade one — Life Sciences: 2. Plants and animals meet their needs in different ways. As a basis for understanding this concept: a. Students know different plants and animals inhabit different kinds of environments and have external features that help them thrive in different kinds of places. c. Students know animals eat plants or other animals for food and may also use plants or even other animals for shelter and nesting. d. Students know how to infer what animals eat from the shapes of their teeth (e.g., sharp teeth: eats meat; flat teeth: eats plants).
Grade one —Investigation and Experimentation: 4. Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept and addressing the content in the other three strands, students should develop their own questions and perform investigations. Students will: e. Make new observations when discrepancies exist between two descriptions of the same object or phenomenon.
Grade two — Life Sciences: 2. Plants and animals have predictable life cycles. As a basis for understanding this concept: a. Students know that organisms reproduce offspring of their own kind and that the offspring resemble their parents and one another. c. Students know many characteristics of an organism are inherited from the parents. Some characteristics are caused or influenced by the environment. d. Students know there is variation among individuals of one kind within a population.
Grade two — Earth Sciences: 3. Earth is made of materials that have distinct properties and provide resources for human activities. As a basis for understanding this concept: e. Students know rock, water, plants, and soil provide many resources, including food, fuel, and building materials, that humans use.
Grade two — Investigation and Experimentation: 4. Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept and addressing the content in the other three strands, students should develop their own questions and perform investigations. Students will: a. Make predictions based on observed patterns and not random guessing. c. Compare and sort common objects according to two or more physical attributes (e.g., color, shape, texture, size, weight). d. Write or draw descriptions of a sequence of steps, events, and observations. g. Follow oral instructions for a scientific investigation.
