Standard:
Store, copy, search, retrieve, modify, and delete information using a computing device, and define the information stored as data.

Descriptive Statement:
Information from the real world can be stored and processed by a computing device. When stored on a computing device, it is referred to as data. Data can include images, text documents, audio files, and video files. Students store, copy, search, retrieve, modify, and delete information using a computing device and define the information stored as data. For example, students could produce a story using a computing device, storing it locally or remotely (e.g., in the cloud). They could then make a copy of the story for peer revision and editing. When the final copy of the story is complete, students delete any unnecessary files. They search for and retrieve data from a local or remote source, depending on where it was stored. (CA CCSS for ELA/Literacy W.K.6, W.K.5, W1.6, W.1.5, W.2.6, W.2.5) Alternatively, students could record their voices singing an age-appropriate song. They could store the data on a computing device, search for peers' audio files, retrieve their own files, and delete unnecesary takes. (VAPA Music K.2.2, 1.2.2, 2.2.2)

Standard:
Compare how people lived and worked before and after the adoption of new computing technologies.

Descriptive Statement:
Computing technologies have changed the way people live and work. Students describe the positive and negative impacts of these changes. For example, as a class, students could create a timeline that includes advancements in computing technologies. Each student could then choose an advancement from the timeline and make a graphic organizer noting how people's lives were different before and after its introduction into society. Student responses could include: In the past, if students wanted to read about a topic, they needed access to a library to find a book about it. Today, students can view and read information on the Internet about a topic or they can download e-books about it directly to a device. Such information may be available in more than one language and could be read to a student, allowing for great accessibility. (HSS.K.6.3) Alternatively, students could retell or dramatize stories, myths, and fairy tales from two distinct time periods before and after a particular computing technology had been introduced. For example, the setting of one story could take place before smartphones had been invented, while a second setting could take place with smartphones in use by characters in the story. Students could note the positive and negative aspects of smartphones on the daily lives of the characters in the story. (VAPA Theatre Arts K.3.1, K.3.2, 1.2.2, 2.3.2) (CA CCSS for ELA/Literacy RL.K.2, RL.K.9, RL.1., RL.1.9, RL.2.2, RL.2.9)

Standard:
Explain why people use passwords.

Descriptive Statement:
Passwords protect information from unwanted use by others. When creating passwords, people often use patterns of familiar numbers and text to more easily remember their passwords. However, this may make the passwords weaker. Knowledge about the importance of passwords is an essential first step in learning about cybersecurity. Students explain that strong passwords are needed to protect devices and information from unwanted use. For example, students could play a game of guessing a three-character code. In one version of the game, the characters are only numbers. In the second version, characters are numbers or letters. Students describe why it would take longer to guess the correct code in the second case. Alternatively, students could engage in a collaborative discussion regarding passwords and their importance. Students may follow-up the discussion by exploring strong password components (combination of letters, numbers, and characters), creating their own passwords, and writing opinion pieces indicating reasons their passwords are strong. (CA CCSS for ELA/Literacy SL.K.1, SL.1.1, SL 2.1, W.1.1, W.2.1)

Standard:
Create patterns to communicate a message.

Descriptive Statement:
Connecting devices to a network or the Internet provides great benefit, but care must be taken to protect devices and information from unauthorized access. Messages can be protected by using secret languages or codes. Patterns help to ensure that the intended recipient can decode the message. Students create a pattern that can be decoded and translated into a message. For example, students could use a table to associate each text character with a number. Then, they could select a combination of text characters and use mathematical functions (e.g., simple arithmetic operations) to transform the numbers associated with the characters into a secret message. Using inverse functions, a peer could translate the secret message back into its original form. (CA CCSS for Mathematics 2.OA.A.1, 2.OA.B.2) Alternatively, students could use icons or invented symbols to represent patterns of beat, rhythm, or pitch to decode a musical phrase. (VAPA Music K.1.1, 1.1.1, 2.1.1, 2.2.2)

Standard:
Explain that the amount of space required to store data differs based on the type of data and/or level of detail.

Descriptive Statement:
All saved data requires space to store it, whether locally or not (e.g., on the cloud). Music, images, video, and text require different amounts of storage. Video will often require more storage and different format than music or images alone because video combines both. The level of detail represented by that data also affects storage requirements. For instance, two pictures of the same object can require different amounts of storage based upon their resolution, and a high-resolution photo could require more storage than a low-resolution video. Students select appropriate storage for their data. For example, students could create an image using a standard drawing app. They could save the image in different formats (e.g., .png, .jpg, .pdf) and compare file sizes. They should also notice that different file sizes can result in differences in quality or resolution (e.g., some pictures could be more pixelated while some could be sharper). Alternatively, in an unplugged activity, students could represent images by coloring in squares within a large grid. They could model how a larger grid requires more storage but also represents a clearer image (i.e., higher resolution).

Standard:
Discuss computing technologies that have changed the world, and express how those technologies influence, and are influenced by, cultural practices.

Descriptive Statement:
New computing technologies are created and existing technologies are modified for many reasons, including to increase their benefits, decrease their risks, and meet societal needs. Students, with guidance from their teacher, discuss topics that relate to the history of computing technologies and changes in the world due to these technologies. Topics could be based on current news content, such as robotics, wireless Internet, mobile computing devices, GPS systems, wearable computing, and how social media has influenced social and political changes. For example, students could conduct research in computing technologies that impact daily life such as self-driving cars. They engage in a collaborative discussion describing impacts of these advancements (e.g., self-driving cars could reduce crashes and decrease traffic, but there is a cost barrier to purchasing them). (CA CCSS for ELA/Literacy W.3.7, W.4.7, W.5.7, SL.3.1, SL.4.1, SL.5.1) Alternatively, students could discuss how technological advancements affected the entertainment industry and then compare and contrast the impacts on audiences. For instance, people with access to high-speed Internet may be able to choose to utilize streaming media (which may cost less than traditional media options), but those in rural areas may not have the same access and be able to reap those benefits. (VAPA Theatre Arts 4.3.2, 4.4.2)

Standard:
Propose ways to improve the accessibility and usability of technology products for the diverse needs and wants of users.

Descriptive Statement:
The development and modification of computing technology is driven by people’s needs and wants and can affect groups differently. Students anticipate the needs and wants of diverse end users and propose ways to improve access and usability of technology, with consideration of potential perspectives of users with different backgrounds, ability levels, points of view, and disabilities. For example, students could research a wide variety of disabilities that would limit the use of traditional computational tools for the creation of multimedia artifacts, including digital images, songs, and videos. Students could then brainstorm and propose new software that would allow students that are limited by the disabilities to create similar artifacts in new ways (e.g., graphical display of music for the deaf, the sonification of images for visually impaired students, voice input for those that are unable to use traditional input like the mouse and the keyboard). (CA CCSS for ELA/Literacy W.3.7, W.4.7, W.5.7) Alternatively, as they anticipate unique user needs, students may consider using both speech and text to convey information in a game. They may also wish to vary the types of programs they create, knowing that not everyone shares their own tastes. (CA NGSS: 3-5-ETS1-1, 3-5-ETS1-2, 3-5-ETS1-3)

Standard:
Describe physical and digital security measures for protecting personal information.

Descriptive Statement:
Personal information can be protected physically and digitally. Cybersecurity is the protection from unauthorized use of electronic data, or the measures taken to achieve this. Students identify what personal information is and the reasons for protecting it. Students describe physical and digital approaches for protecting personal information such as using strong passwords and biometric scanners. For example, students could engage in a collaborative discussion orally or in writing regarding topics that relate to personal cybersecurity issues. Discussion topics could be based on current events related to cybersecurity or topics that are applicable to students, such as the necessity of backing up data to guard against loss, how to create strong passwords and the importance of not sharing passwords, or why we should keep operating systems updated and use anti-virus software to protect data and systems. Students could also discuss physical measures that can be used to protect data including biometric scanners, locked doors, and physical backups. (CA CCSS for ELA/Literacy SL.3.1, SL.4.1, SL.5.1)

Standard:
Create patterns to protect information from unauthorized access.

Descriptive Statement:
Encryption is the process of converting information or data into a code, especially to prevent unauthorized access. At this level, students use patterns as a code for encryption, to protect information. Patterns should be decodable to the party for whom the message is intended, but difficult or impossible for those with unauthorized access. For example, students could create encrypted messages via flashing a flashlight in Morse code. Other students could decode this established language even if it wasn't meant for them. To model the idea of protecting data, students should create their own variations on or changes to Morse code. This ensures that when a member of that group flashes a message only other members of their group can decode it, even if other students in the room can see it. (CA NGSS: 4-PS4-3) Alternatively, students could engage in a CS Unplugged activity that models public key encryption: One student puts a paper containing a written secret in a box, locks it with a padlock, and hands the box to a second student. Student 2 puts on a second padlock and hands it back. Student 1 removes her lock and hands the box to student 2 again. Student 2 removes his lock, opens the box, and has access to the secret that student 1 sent him. Because the box always contained at least one lock while in transit, an outside party never had the opportunity to see the message and it is protected.

Standard:
Represent data in multiple ways.

Descriptive Statement:
Computers store data as sequences of 0s and 1s (bits). Software translates to and from this low-level representation to higher levels that are understandable by people. Furthermore, higher level data can be represented in multiple ways, such as the digital display of a color and its corresponding numeric RGB value, or a bar graph, a pie chart, and table representation of the same data in a spreadsheet. For example, students could use a color picker to explore the correspondence between the digital display or name of a color (high-level representations) and its RGB value or hex code (low-level representation). Alternatively, students could translate a word (high-level representation) into Morse code or its corresponding sequence of ASCII codes (low-level representation).
