Washington DC Standards for First Grade Science

DC.1.1. Scientific Thinking and Inquiry: Broad Concept: Scientific progress is made by asking relevant questions and conducting careful investigations. As a basis for understanding this concept, and to address the content in this grade, students should develop their own questions and perform investigations. Students:

1.1.1. Observe, describe, draw, and sort objects as a way of isolating and categorizing some of their properties.

1.1.4. Use tools, such as rulers and magnifiers, to investigate the world and make observations.

1.1.5. Measure the length of objects having straight edges in centimeters or non-standard units to the nearest unit.

1.1.6. Demonstrate that magnifiers help people see small features of objects.

1.1.7. Describe and compare objects in terms of number, shape, texture, size, mass, color, and motion.

DC.1.2. Earth Science: Broad Concept: The Earth is composed of land, air, and water. As a basis for understanding this concept, students:

1.2.2. Investigate and explain that air is a mixture of different gases that surrounds us and takes up space, and whose movement we feel as wind.

DC.1.3. Physical Science: Broad Concept: The motion of objects can be observed, measured, and changed. As a basis for understanding this concept, students:

1.3.1. Observe and describe that the way to make something move (faster or slower or in a different direction) is by giving it a push or a pull, which is called a force.

1.3.4. Recognize and demonstrate how things near Earth fall to the ground unless something holds them up (they are subject to the force of gravity).

DC.1.4. Life Science: Broad Concept: Different types of plants and animals inhabit the Earth. As a basis for understanding this concept, students:

1.4.1. Explain that most living things need food, water, and air.

1.4.3. Observe and explain that animals eat plants and/or other animals for food.

1.4.4. Recognize that animals (including humans) and plants are living things that grow, reproduce, and need food, air, and water.

1.4.5. Identify the external features that local plants and animals have (such as those found in schoolyards or in city neighborhoods) that enable them to survive in their environment.
