Hello and Welcome! In this book you will find curated resources, lessons, and ideas for you to integrate the New York State Education Computer Science and Digital Fluency standards into your curriculum. These standards should not add to your load, but rather enhance your lessons. The activities should integrate into what you already do.

Explore the resources for your grade level, but be sure to also explore the resources in other grade levels as they may still apply with slight alterations, or it might spark an idea for something you can use. Not all of the lessons and activities are free and they are marked as paid if a purchase or subscription is needed. As always, check with your school administration and technology department before you sign up or use any tool that collects personally identifiable information (PII). Make sure the tools align with your Edlaw 2D approved list for your district.

If you have ideas you would like to add, please reach out! We want this to be something useful for all!

Misha Leder, a Software Engineer at Google has an activity called Message Routing which can be a nice extension activity. Internet works this way - computer networks are connected with each other via routers. Have kids sit at several tables, every child being a server. Have representatives for each tables to act as routers. Kids write messages to each other and routers help routing this messages.

eGFI-K12 has a complete lesson plans with a maths flavour Traffic Flow. Designed for advanced high-school algebra students, it can be worked out most easily using Microsoft Excel. Explore traffic engineering further with a competition developed at the University of Toronto, an animated diagram, and a game called Gridlock Buster.

So how do I protect my data?

We're already well on our way, but now it's time to actually take action. Get started today with one of the solutions below to better protect your data!

Create at least one Backup on #WorldBackupDay!

Go through the steps below and read how you can easily secure your files via backups and how you can improve the security per device and solution. March 31st is WorldBackupDay: the day to prevent data loss!

Online Backup Services

Keeping your backup in the cloud is a good and future-proof alternative to physical data storage, instead of an external hard drive or USB stick. An external hard drive or USB stick can be lost or damaged. The biggest advantage of storing files in the cloud is that they are available anytime, anywhere. In terms of security, you should always pay close attention to access and security with cloud backups.

Also check out: Best Backup Software!

Below we list the best-known parties where you can make a backup in the cloud. Many of the companies below also offer a few GB of free space online.

Cloud Backup
For full backups: Backblaze or iDrive

Cloud Storage For storing a smaller amount of photos or files:

MEGA - 20 GB Free

pCloud - 10 GB Free

Apple iCloud - 5 GB Free

OneDrive - 5 GB Free

Google Cloud - 15 GB Free
There are more services like this though, Google 'Best Smartphone Backup' and you'll see many top lists from different blogs and experts!

External Storage Backup

External Hard Disk Drives (HDD)

External hard drive backups are still quite popular. Please note that you do not use a good backup method if you then keep the physical backup at home or on the same PC. Safe storage of an external hard drive is important.

External hard drives are mainly used for data storage and PC backups. The biggest disadvantage of an external hard drive is that the hard drive can break down or get lost. Physical external hard drives are often not handled with care or they are collecting dust for too long. The biggest advantage is that the storage space only needs to be purchased once. It is also a nice addition to a cloud or online backup. Don't forget to update your physical hard drive every year.

An external hard drive is usually available at web shops that sell other electrical hardware. You can purchase external hard drives from e-commerce platforms such as Amazon.com and BestBuy.

External Solid State Drive: (SSD)

The advantage of an SSD Backup vs an HDD Backup is faster access to data by using memory chips rather than a physical spinning disk that's found in hard drives. : The speed difference between an SSD vs a hard drive is most apparent when copying and moving huge files. HDDs can copy 30 to 150 MB per second (MB/s), while standard SSDs perform the same action at speeds of 500 MB/s. (Source: Backblaze.com) Since SSDs don't contain moving parts, they're less prone to damage if you drop or bang your computer.

SSDs are usually available at web shops that sell other electrical hardware already mentioned above.

Computer Backup

Where you previously had freedom of choice regarding making a backup, and you could easily make multiple choices from the operating system on your computer. Now the PC operating systems are mainly promoting and integrating their own cloud services. However, there are still several options for making a backup. Before you go into business with a storage or backup service, you should only thoroughly familiarize yourself with the backup providers. This is partly due to the fact that you can no longer properly select these options from, for example, Windows itself.

Creating a Computer / PC Backup with Windows operating system

Make a backup of your PC on an external (and connected) hard drive via "Backup Settings".

Make a backup of your PC on OneDrive via "Settings for Backups".

Select a party specialized in Backups and have your PC made a backup via the service or application of the service.

Some commonly used PC Backup specialists: Backblaze, iDrive

Creating a Computer Backup with macOS operating system

Make a basic backup of your Mac on an external hard drive via Time Machine. Go to System Settings, search for Time Machine, and add the backup disk.
Back up some of your data to iCloud (subscription required).
For greater control over your backup setup, you can select a company that is specialized in backups and use their software.
A commonly used Mac Backup specialist: Carbon Copy Cloner.

Backup Smartphone

It often goes wrong here! Did you know that a backup with, for example, iPhone does not store your photos and documents? 9 out of 10 times these images are stored in your iCloud and therefore not on backups. (1*) So is your iCloud account stolen or hacked? Then you can still lose everything. In addition, these backups pushed from operating systems are often stored in the cloud storage of expensive services, there are cheaper alternatives!
How ​​do you solve this?
Super easy.. Use another cloud storage or backup party for backups of your crucial files. Various backup services provide additional security and safe distance from the original files.
If you seek additional backup services for smartphone backups.

MEGA - 20 GB Free

pCloud - 5 GB Free

Apple iCloud - 5 GB Free (If you want to differentiate from Android systems)

OneDrive - 5 GB Free

Google Cloud - 15 GB Free (If you want to differentiate from IoS systems)
There are more though, Google 'Best Smartphone Backup' and you'll see many top lists from different blogs and experts.

Creating a NAS Backup

Backing up to a NAS is a good safe way to backup mainly for small businesses, Tech-Savvy PC users, and smart homes. NAS is an abbreviation for Network Attached Storage. A NAS Server is a kind of computer cabinet that can convert one or more hard drives into one wireless network storage via a wireless connection.

A NAS is usually available at Webshops that sell electrical products. You can purchase a NAS from web shops such as Amazon.com and BestBuy

Other Backup Methods

Obviously, there are more methods for making backups. Both online and offline. Actually, there are too many topics to deal with per device, but we will mention most of them here briefly:

Backup via USB stick
One of the old and still effective methods is to use a USB stick, this is an easy method. Insert the USB stick into the Computer or Laptop and drag the files you want to save on the USB stick to the correct folder.

Backup from a MAC
Go to System Preferences and then Time Machine and follow the instructions within the Time Machine application to backup your Mac.

Back up your Website
If you want to make a backup of your website, open the file manager via the web hosting company or via an FTP server. Copy all folders from the website to a folder on the hard disk or to a cloud storage provider.

Back up Whatsapp
Whatsapp can be backed up via the export functionality or via the backup function, these backups (outside the export) can only be saved with the operating system. So iCloud with iPhones and with Android to Google Drive.

Secure Encrypted Backup Solutions
When you have sensitive data you need to back up consider using data-encrypted backup solutions. The Whitehouse recently said the following regarding using data encrypted backup solutions:
"Back up your data, system images, and configurations, regularly test them, and keep the backups offline: Ensure that backups are regularly tested and that they are not connected to the business network, as many ransomware variants try to find and encrypt or delete accessible backups. Maintaining current backups offline is critical because if your network data is encrypted with ransomware, your organization can restore systems."
Take the pledge
