## Kindergarten

#### CCSS.ELA-Literacy.RI.K.3 [CCSS page]

With prompting and support, describe the connection between two individuals, events, ideas, or pieces of information in a text.

### Suggested Lesson:

From a book or pictures, identify common objects in their states such as ice cubes, a glass of juice or helium in a balloon.

## Fifth Grade

#### CCSS.ELA-Literacy.W.5.7 [CCSS page]

Conduct short research projects that use several sources to build knowledge through investigation of different aspects of a topic.

### Suggested Lesson:

Most people think that there are only three states of matter, but there are actually five. Find out what the other two states are and describe details of them such as when they happen, how they happen and at what temperature they happen.

## First Grade

#### CCSS.Math.Content.1.MD.C.4 [CCSS page]

Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.

### Suggested Lesson:

List, sort, and count all of the solids, liquids and gases that your class can find using a picture or photo that contains multiple examples of the three states of matter or use this sort of activity. Create a graph of the findings.

## 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.

#### CCSS.Math.Content.3.MD.A.2

Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l).¹ Add, subtract, multiply, or divide to solve one-step word problems involving masses or volumes that are given in the same units, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem.²

### Suggested Lesson:

Measure how long it takes for an ice cube to completely change to liquid state at room temperature. Compare to the length of time it takes to change an equal amount of water to water vapor at room temperature.

## Sixth Grade

#### CCSS.Math.Content.6.NS.C.5 [CCSS page]

Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, positive/negative electric charge); use positive and negative numbers to represent quantities in real-world contexts, explaining the meaning of 0 in each situation.

### Suggested Lesson:

Absolute 0 is a temperature at which there is absolutely no molecular activity and which scientists continue to attempt to achieve. Use this interactive scale to determine common temperatures of things found in nature and around us. With teacher help, calculate differences for temperatures above and below freezing.
