 In racket you can create what are known as "local bindings" which are functions that are local (belong to) a parent function. You can define these individually with another define function, or to define them by using `let` or `let*`, with the latter letting later bindings use earlier bindings. Both of them let you define more than one binding at once.
 
 It was also noted how identifiers were scoped within a language, with a function arguemnt being avialable throughout the function, and when a variable is not in scope, it does not "exist" so can therefor be defined again, like in this example

+In this lab I learned about Racket recursion techniques.

+## Rainbow example
+I had great difficulty in getting the rainbow code to work. I ended up with a working definition but not much time to do much else. My function follows:
+```racket
+(define (rainbow2 p)
+  (define (color-mapper gr-obj color-list)
+    (cond
+      [(empty? color-list) empty]
+      [else (cons(colorize gr-obj (first color-list))
+        (color-mapper gr-obj (rest color-list)))]))
+        (color-mapper p (list "red" "orange" "yellow" "green" "blue" "purple")))
+```
+This deines a function called rainbow 2, which then defines another function called color mapper. color mapper checks if there is an empty list, and if so, ends. If there is not an empty list, it calls the colorize function with the first item in the list, with the passed in graphical object. If then recursivly does this until the list is empty, since each recursive call removes an item from the start of the list. In the end you get a set of colored objects in the order of the function call at the end of the definition of rainbow 2.
+## Conclusion
+I did not do much of the lab as assigned, because of my difficulty in making the program. My understanding of how my program works after getting it working will help me in getting future labs done on time
