This activity will begin with a short review of "My Robotic Friends," then will quickly move to a race against the clock, as students break into teams and work together to write a program one instruction at a time.

At some point we reach a physical limit of how fast we can send bits and if we want to send a large amount of information faster, we have to find a way to represent the same information with fewer bits - we must **compress** the data. In this lesson, students will use the Text Compression Widget to compress segments of English text by looking for patterns and substituting symbols for larger patterns of text.

In this lesson, students are introduced to the need for encryption and simple techniques for breaking (or cracking) secret messages. Students try their own hand at cracking a message encoded with the classic Caesar cipher and also a Random Substitution Cipher. Students should become well-acquainted with idea that in an age of powerful computational tools, techniques of encryption will need to be more sophisticated. The most important aspect of this lesson is to understand how and why encryption plays a role in all of our lives every day on the Internet, and that making good encryption is not trivial. Students will get their feet wet with understanding the considerations that must go into making strong encryption in the face of powerful computational tools that can be used to crack it. The need for secrecy when sending bits over the Internet is important for anyone using the Internet.

Students will learn that events are a useful way to control when an action happens, and can even be used to make make multiple things act in sync. In programming, you can use events to respond to a user controlling it (like pressing buttons or clicking the mouse). Events can make your program more interesting and interactive.

ILLUMINE community platform (https://illumine.upf.edu/) fosters a community of teachers based around evidence-based teaching practices.

The platform is an interactive, online resource for educators. It enables teachers to create, reuse (copy, share, customise) research lessons and the learning activities within such research lessons. The research lessons functionality scaffolds teacher inquiry processes.

It also enables teachers to learn about evidence-based teaching strategies (retrieval practice, distributed practice, reframing, spaced learning), access resources for applying the strategies with students, get inspiration from the experiences of teaching peers.

Additionally, the website hosts or links to all project outputs (Workshop Toolkit, Digital Handbook, Mini-MOOC on the science of learning, Classroom materials, etc.), describes the project and its objectives, and contains the news updates on project activities.
