Science Topics Covered this Year in Second Grade
Nature of Science- Students will raise questions about the natural world, investigate them in teams through free exploration and systematic observations, and generate appropriate explanations based on those explorations.
Topic 2: Properties of Matter- Students will observe and measure objects in terms of their properties, including size, shape, color, temperature, weight,texture, sinking or floating in water, and attraction and repulsion of magnets.
Topic 3: Changing Matter- Students will investigate that materials can be altered to change some of their properties,but not all materials respond the same way to any one alteration.
Topic 4: Uses of Energy/Energy, Force, and Motion- Students will discuss that people use electricity or other forms of energy to cook their food, cool or warm their homes, and power their cars.
Topic 4: Forces and Motion/Energy, Force, and Motion-Students will investigate the effect of applying various pushes and pulls on different objects.
Topic 1: Rocks and Soil/Earth's Surface and Weather- Students will recognize that Earth is made up of rocks. Rocks come in many sizes and shapes. Describe how small pieces of rock and dead plant and animal parts can be the basis of soil and explain the process by which soil is formed. Classify soil types based on color, texture (size of particles), the ability to retain water, and the ability to support the growth of plants.
Topic 1: Weather/Earth's Surface and Weather- Student will compare and describe changing patterns in nature that repeat themselves, such as weather conditions including temperature and precipitation, day to day and season to season. Investigate by observing and measuring, that the Sun's energy directly and indirectly warms the water, land, and air. Investigate, observe and describe how water left in an open container disappears (evaporates), but water in a closed container does not disappear(evaporate). Investigate that air is all around us and that moving air is wind. Measure and compare temperatures taken every day at the same time.
Topic 5: Human Body-Student will distinguish human body parts (brain, heart, lungs, stomach, muscles, and skeleton) and their basic functions. Ask "how do you know?" in appropriate situations and attempt reasonable answers when asked the same question by others.
Topic 5: Life Cycles/Plants and Animals-Students will observe and describe major stages in the life cycles of plants and animals, including beans and butterflies. We will observe and record the stages of a chicken's life cycle by hatching chicks in our classroom.
Topic 6: Basic Needs/Habitats-Students will compare and contrast the basic needs that all living things, including humans, have for survival. Recognize and explain that living things are found all over Earth, but each is only able to live in habitats that meet its basic needs.
