CCSS.ELA-Literacy.W.K.2 [CCSS page]

Use a combination of drawing, dictating, and writing to compose informative/explanatory texts in which they name what they are writing about and supply some information about the topic.

Suggested Lesson

Draw a solid, a liquid and a gas and describe them in a sentence each.

Third Grade

CCSS.ELA-Literacy.SL.3.6 [CCSS page]

Speak in complete sentences when appropriate to task and situation in order to provide requested detail or clarification. (See grade 3 Language standards 1 and 3 here for specific expectations.)

Suggested Lesson

Play this physical properties game: Hide an object inside a paper bag. Make a list of ten physical properties that apply to that object and the read the list aloud to the class. Have students use their critical thinking skills and knowledge of physical propertied to try and identify the object. Include as much detail as possible without giving too much away.

Sixth Grade

CCSS.ELA-Literacy.W.6.1 [CCSS page]

Write arguments to support claims with clear reasons and relevant evidence.

Suggested Lesson

Place 3D objects inside a shoebox. Allow students to tilt, shake and listen to the contents. From their “observations” of approximate weight, size, shape, and other physical properties, determine how many objects are in the box and what shape they have. Write a paragraph describing the object(s). Open the box and compare the objects to the students' written assessments. Discuss how scientists often make determinations about atoms and their sub-particles based on experiments of things they cannot actually observe. Share this Q&A on How do we really know atoms exist with the class after doing this activity.


Second Grade

CCSS.Math.Content.2.MD.B.5 [CCSS page]

Use addition and subtraction within 100 to solve word problems involving lengths that are given in the same units, e.g., by using drawings (such as drawings of rulers) and equations with a symbol for the unknown number to represent the problem.

Suggested Lesson

Using paper versions of thermometers, fill in the thermometers to identify freezing and boiling points on both a Fahrenheit and Celsius scale. Practice reading temperature and temperature changes too. Get some thermometer worksheets here.

Third Grade

CCSS.Math.Content.3.MD.A.1 [CCSS page]

Second Grade

Physical Sciences: PS1-2-1 [ICS page]

Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.

Supporting Content:

Different kinds of matter exist and many of them can be solid, liquid, or gas depending on temperature. Matter can be described and classified by its observable properties. Observations could include color, strength, texture, hardness, and flexibility. Patterns could include the similar properties that different materials share.

Physical Sciences: PS1-2-3 [ICS page]

Make observations to construct an evidence-based account of how an object made of a small set of pieces can be disassembled and made into a new object.

Supporting Content:

A great variety of objects can be built up from a small set of pieces. Examples of pieces could include blocks, building bricks, or other assorted small objects.

Physical Sciences: PS1-2-4 [ICS page]

Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot.

Supporting Content:

Heating or cooling a substance may cause changes that can be observed. Sometimes these changes are reversible, and sometimes they are not. Examples of reversible changes could include materials such as water and butter at different temperatures. Examples of irreversible changes could include cooking an egg, freezing a plant leaf, and heating paper.

Fifth Grade

Physical Sciences: PS1-5-1 [ICS page]

Develop a model to describe that matter is made of particles too small to be seen.

Supporting Content:

Matter of any type can be subdivided into particles that are too small to see, but even then the matter still exists and can be detected by other means. A model showing that gases are made from matter particles that are too small to see and are moving freely around in space can explain many observations, including the inflation and shape of a balloon and the effects of air on larger particles or objects. Other examples of evidence supporting a model could include compressing air in syringe, dissolving sugar in water, and evaporating salt water.

Physical Sciences: PS1-5-2 [ICS page]

Measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling, or mixing substances, the total weight of matter is conserved.

Supporting Content:

The amount (weight) of matter is conserved when it changes form, even in transitions in which it seems to vanish. No matter what reaction or change in properties occurs, the total weight of the substances does not change. Examples of reactions or changes could include phase changes, dissolving, and mixing that form new substances.

Physical Sciences: PS1-5-3 [ICS page]

Make observations and measurements to identify materials based on their properties.

Supporting Content:

Measurements of a variety of properties can be used to identify materials. Examples of materials to be identified could include baking soda and other powders, metals, minerals, and liquids. Examples of properties could include color, hardness, reflectivity, electrical conductivity, thermal conductivity, response to magnetic forces, and solubility.

Physical Sciences: PS1-5-4 [ICS page]

Conduct an investigation to determine whether the mixing of two or more substances results in new substances

Supporting Content:

When two or more different substances are mixed, a new substance with different properties may be formed.

Sixth Grade/Middle School

Physical Sciences: PS1-MS-1 [ICS page]

Develop models to describe the atomic composition of simple molecules and extended structures.

Supporting Content:

Substances are made from different types of atoms, which combine with one another in various ways. Atoms form molecules that range in size from two to thousands of atoms. Emphasis is on developing models of molecules that vary in complexity. Examples of simple molecules could include ammonia and methanol. Examples of extended structures could include sodium chloride or diamonds. Examples of molecular-level models could include drawings, 3D ball and stick structures, or computer representations showing different molecules with different types of atoms.

Physical Sciences: PS1-MS-2 [ICS page]

Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.

Supporting Content:

Each pure substance has characteristic physical and chemical properties (for any bulk quantity under given conditions) that can be used to identify it. Substances react chemically in characteristic ways. In a chemical process, the atoms that make up the original substances are regrouped into different molecules, and these new substances have different properties from those of the reactants. Assessment may include analysis of the following properties: density, melting point, boiling point, solubility, flammability, and odor. Examples of reactions could include burning sugar or steel wool, fat reacting with sodium hydroxide, and mixing zinc with hydrogen chloride.

Physical Sciences: PS1-MS-3 [ICS page]

Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.

Supporting Content:

In a chemical process, the atoms that make up the original substances are regrouped into different molecules, and these new substances have different properties from those of the reactants. Emphasis is on natural resources that undergo a chemical process to form the synthetic material. Examples of new materials could include new medicine, foods, and alternative fuels.

Physical Sciences: PS1-MS-4 [ICS page]

Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.

Supporting Content:

The changes of state that occur with variations in temperature or pressure can be described and predicted using these models of matter. Emphasis is on qualitative molecular-level models of solids, liquids, and gases to show that adding or removing thermal energy increases or decreases kinetic energy of the particles until a change of state occurs. Examples of models could include drawings and diagrams. Examples of particles could include molecules or inert atoms. Examples of pure substances could include water or carbon dioxide (compounds.)

Physical Sciences: PS1-MS-5 [ICS page]

Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.

Supporting Content:

Substances react chemically in characteristic ways. In a chemical process, the atoms that make up the original substances are regrouped into different molecules, and these new substances have different properties from those of the reactants. However, the total number of each type of atom is conserved, and thus the mass does not change. Emphasis is on law of conservation of matter and on physical models or drawings, including digital forms, that represent atoms.

Physical Sciences: PS1-MS-6 [ICS page]

Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.

Supporting Content:

Some chemical reactions release energy, others store energy. The temperature of a system is proportional to the average internal kinetic energy and potential energy per atom or molecule (whichever is the appropriate building block for the system's material). The details of that relationship depend on the type of atom or molecule and the interactions among the atoms in the material. Temperature is not a direct measure of a system's total thermal energy. The total thermal energy (sometimes called total internal energy) of a system depends jointly on the temperature, the total number of atoms in the system, and the state of the material. Emphasis is on the design, controlling the transfer of energy to the environment, and modification of a device using factors such as type and concentration of a substance. Examples of designs could involve chemical reactions such as dissolving ammonium chloride or calcium chloride. A solution needs to be tested, and then modified on the basis of the test results in order to improve it. The iterative process of testing the most promising solutions and modifying what is proposed on the basis of the test results leads to greater refinement and ultimately to an optimal solution.

Life Sciences LS1-MS-6 [ICS page]

Develop a model to describe how food is rearranged through chemical reactions, forming new molecules that support growth and/or release energy as this matter moves through an organism.

Supporting Content:

Within individual organisms, food moves through a series of chemical reactions (cellular respiration) in which it is broken down and rearranged to form new molecules, to support growth, or to release energy. Emphasis is on describing that molecules are broken apart and put back together and that in this process, energy is released. Also understanding that the elements in the products are the same as the elements in the reactants.
