Science Worksheets and Study Guides Second Grade. Hands-on Lab Skills/Science Inquiry

The resources above correspond to the standards listed below:

Washington Standards

WA.2. Inquiry (INQ)
2-3.INQ. Conducting Investigations: In prior grades students learned that scientific investigations involve trying to answer questions by making observations or trying things out. In grades 2-3 students learn to conduct different kinds of investigations. Although students may not yet be able to plan investigations alone, they can carry out investigations in collaboration with other students and support from the teacher. Actions may include observing and describing objects, events, and organisms, classifying them and making and recording measurements. Students should also display their data using various tables and graphs, make inferences based on evidence, and discuss their results with other students.
2-3 INQB. Investigate: Students know that a scientific investigation may include making and following a plan to accurately observe and describe objects, events, and organisms; make and record measurements, and predict outcomes.
2-3 INQB.1. Students are expected to work with other students to make and follow a plan to carry out a scientific investigation. Actions may include accurately observing and describing objects, events, and organisms; measuring and recording data; and predicting outcomes.
2-3 INQD. Investigate: Students know that simple instruments, such as magnifiers, thermometers, and rulers provide more information than scientists can obtain using only their unaided senses.
2-3 INQD.1. Students are expected to use simple instruments (e.g., metric scales or balances, thermometers, and rulers) to observe and make measurements, and record and display data in a table, bar graph, line plot, or pictograph.
WA.4. Physical Science
PS2. Matter: Properties and Change
2-3.PS2. Properties of Materials: In prior grades students learned about liquids and solids. In grades 2-3 students learn to identify different physical properties of materials (matter) and to realize that an object may be made from several different types of materials. They also learn that properties of materials change when environmental conditions change. Water, for example, changes to a solid when the temperature drops below 0 degrees Celsius. Although few students at this age will fully understand that water may change to an invisible gas (e.g., water vapor) when left in an open container overnight, they can start to become familiar with changes of state by observing ice cubes freeze and then melt, and seeing water turn to steam when heated. Looking closely at matter to describe its characteristics will eventually lead to understanding the basic nature of matter and its physical and chemical properties.
2-3.PS2A. Students know that objects have properties, including size, weight, hardness, color, shape, texture, and magnetism. Unknown substances can sometimes be identified by their properties.
2-3.PS2A.1. Students are expected to list several properties of an object.
2-3.PS2B. Students know that an object may be made from different materials. These materials give the object certain properties.
2-3.PS2B.1. Students are expected to list properties of common materials.
