# Chemistry: Standards

## Language

## Kindergarten

#### 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.

## Math

## 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]

Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.

### Suggested Lesson

In a glass container, mix ¼ cup vinegar with 1 tablespoon of baking soda. Watch the reaction. When it has stopped creating foam, add an antacid tablet such as a Rolaid or a Tums. Measure with a stopwatch to see how long the mixture takes to deplete the bubbles to almost nothing.

## Fifth Grade

#### CCSS.Math.Content.5.NBT.B.6 [CCSS page]

Find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.

### Suggested Lesson

Measure and calculate the density of several liquids. Find instructions for this activity here.
