SC.2.P.8.1

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.
General Information
Subject Area: Science
Grade: 2
Body of Knowledge: Physical Science
Idea: Level 1: Recall
Big Idea: Properties of Matter - A. All objects and substances in the world are made of matter. Matter has two fundamental properties: matter takes up space and matter has mass.

B. Objects and substances can be classified by their physical and chemical properties.

Mass is the amount of matter (or "stuff") in an object. Weight, on the other hand, is the measure of force of attraction (gravitational force) between an object and Earth.

The concepts of mass and weight are complicated and potentially confusing to elementary students. Hence, the more familiar term of "weight" is recommended for use to stand for both mass and weight in grades K-5. By grades 6-8, students are expected to understand the distinction between mass and weight, and use them appropriately.


Clarification for grades K-2: The use of the more familiar term ‘weight’ instead of the term “mass” is recommended for grades K-2.

Clarification for grades 3-5: In grade 3, introduce the term mass as compared to the term weight. In grade 4, investigate the concept of weight versus mass of objects. In grade 5, discuss why mass (not weight) is used to compare properties of solids, liquids and gases.

Assessment

Classification Performance Task:

Using simple items, colored shapes, students use a binary classification system to divide objects, then justify their scheme.

The task assesses primary students' abilities to perform process skills such as classification by using observable differences and similarities.

This task is designed to take students approximately 8 minutes to complete.

Type: Assessment

Lesson Plans

Candy Homes:

In this project based learning experience, students explore and sort different candies based on their physical properties and how they can be altered and changed. They will determine which properties of the candy would be most beneficial to build a successful home/structure. Students will create a model of their home using their chosen candy and support their choice by writing an opinion and preparing a presentation.

Type: Lesson Plan

Animal Sanctuary Engineering Design Challenge:

This Engineering Design Challenge is a hands-on investigation in both math and science. Students will be able to use prior knowledge and problem solving skills to solve non-routine problems and real-world situations, using mathematical and scientific models. It is a great way to introduce your students to real-world problem solving. Students will be engaged in hands-on learning by designing and creating an enclosure for zoo animals. Both math and science standards have been incorporated for an integrated lesson.

Type: Lesson Plan

May the Force Be With You:

In this lesson plan, students will explore what items are attracted to magnets. They will learn that magnets have an invisible force called a magnetic field and that objects can be moved without even touching them.

Type: Lesson Plan

Rocks, Rocks, Everywhere:

The students will be able to sort rocks based upon color, hardness, texture, layering and particle size.

Type: Lesson Plan

Classifying Candy 1:

Students will develop two binary classification systems using concrete objects. The classification systems will be based on two different properties of the concrete objects.

The task assesses students' abilities to make simple observations and apply their understanding to classification.

This task is designed to take students approximately 10-15 minutes to complete.

The Shape of Kisses:

This resource features a lesson plan for comparing the properties of Hershey's chocolate kisses in different states: solid and liquid.

Type: Lesson Plan

Sink or Float? Inquiry Investigation:

Students will predict which objects sink or float in water. They will observe, describe, and keep records about what happens when objects are placed in water, and determine whether there is consistency in their own and classmates' results. They will generate ideas about characteristics of materials that sink or float, and will ask questions about physical properties of matter.

Type: Lesson Plan

Float or Sink?:

This lesson builds on lessons regarding the different properties of solids by having students explore how different objects float or sink when placed in water.

Type: Lesson Plan

It's Attracted:

In this lesson, students will use informational text to gather information on objects made of matter that have properties that make them either attracted or not attracted to magnets.

Type: Lesson Plan

You Name It!:

Students are given a variety of materials and asked to identify each material as a solid, liquid or gas. They use their five senses — sight, sound, smell, texture and taste — to identify the other characteristics of each item.
