 ## Objects
 
+In this activity, we'll explore some additional concepts that you'll encounter in more depth later on in the course.
+
 Open the Chrome devtools Console, type in `console.log` and then hit enter
 
 What output do you get?
 
-undefined/ f log() native code
 Now enter just `console` in the Console, what output do you get back?
 
-a list of all console types and how to use them
 Try also entering `typeof console`
 
-object
 Answer the following questions:
 
 What does `console` store?
 What does the syntax `console.log` or `console.assert` mean? In particular, what does the `.` mean?
-What does `console` store? The console object provides access to the debugging console. It stores text and data explicitly sent to it using methods like console.log() or console.info()
-What does the syntax `console.log` or `console.assert` mean?
-The assert() method writes a message to the console if an expression evaluates to false. The log() method writes (logs) a message to the console.
-In particular, what does the `.` mean?
-This is a Dot Notation, it is used to access an object's properties or methods
