Minnesota Standards for Second Grade Science

MN.2.1. The Nature of Science and Engineering

2.1.1. The Practice of Science

2.1.1.2. The student will understand that scientific inquiry is a set of interrelated processes incorporating multiple approaches that are used to pose questions about the natural world and investigate phenomena.
2.1.1.2.1. Raise questions about the natural world and seek answers by making careful observations, noting what happens when you interact with an object, and sharing the answers with others.

MN.2.2. Physical Science

2.2.1. Matter

2.2.1.1. The student will understand that objects can be described in terms of the materials they are made of and their physical properties.
2.2.1.1.1. Describe objects in terms of color, size, shape, weight, texture, flexibility, strength and the types of materials in the object.
2.2.1.2. The student will understand that the physical properties of materials can be changed, but not all materials respond the same way to what is done to them.
2.2.1.2.1. Observe, record and recognize that water can be a solid or a liquid and can change from one state to another and that the amount of water stays the same when it melts and freezes.

2.2.2. Motion

2.2.2.1. The student will understand that the motion of an object can be described by a change in its position over time.
2.2.2.1.2. Demonstrate that objects move in a variety of ways, including a straight line, a curve, a circle, back and forth, and at different speeds.
2.2.2.2. The student will understand that the motion of an object can be changed by push or pull forces.
2.2.2.2.1. Describe how push and pull forces can make objects move.
2.2.2.2.2. Describe how things near Earth fall to the ground unless something holds them up.

MN.2.3. Earth and Space Science

2.3.2. Interdependence Within the Earth System

2.3.2.2. The student will understand that weather can be described in measurable quantities and changes from day to day and with the seasons.
2.3.2.2.1. Measure, record and describe weather conditions using common tools.

MN.2.4. Life Science

2.4.2. Interdependence in Living Systems

2.4.2.1. The student will understand that natural systems have many components that interact to maintain the living system
2.4.2.1.1. Recognize that plants need space, water, food and air and they fulfill these needs in different ways.

2.4.3. Evolution in Living Systems

2.4.3.1. The student will understand that plants and animals undergo a series of orderly changes during their life cycles.
2.4.3.1.1. Describe the characteristics of plants at different stages of their life cycles.
