 For students that are new to programming, here are some sample programs (what we call learning labs) that you can try.  You can learn by reading the sample programs, going to the Trinkit.io site and changing some values in the code.  Each of the labs has experiments at the end you can do to extend to see if you have mastered the concepts before you go on to the next lab.

+## Random Circles
+
+In this exercise we will draw 5 stars of different colors:
+The colors are randomly picked from the list of colors
+```
+colorList = ['red', 'orange', 'green', 'blue', 'purple', 'pink', 'brown', 'gray', 'gold']
+mycolor = colorList[random.randint(0,len(colorList)-1)]
+```
+After these line runs, the variable mycolor will be assigned some random color from the list of colors myColorList.   We will then use this color to fill a star.
+The stars are drawn at random locations selected in  x = random.randint(-max_distance, max_distance)
+   y = random.randint(-max_distance, max_distance)
+   The size of star is also randomly picked size = random.randint(15, 30)
+
+## Sample Code
+```python
+import turtle
+import random
+# this is a list of colors
+colorList = ['red', 'orange', 'green', 'blue', 'purple', 'pink', 'brown', 'gray', 'gold']
+dan = turtle.Turtle()
+dan.shape('turtle')
+dan.delay(1)
+dan.clear()
+dan.penup()
+
+max_distance = 160
+
+# draw an eight sided star
+def star(x, y, size, color):
+  dan.goto(x, y)
+  dan.color(colorList[random.randint(0,len(colorList)-1)])
+  dan.pendown()
+  dan.begin_fill()
+  for i in range(1,8):
+     dan.forward(size)
+     dan.right(150)
+     dan.forward(size)
+     dan.left(100)
+  dan.end_fill()
+  dan.right(10)
+  dan.penup()
+
+# draw a pattern at a random location on the screen
+for i in range(5):
+   x = random.randint(-max_distance, max_distance)
+   y = random.randint(-max_distance, max_distance)
+   size = random.randint(15, 30)
+   color_index = random.randint(0,8)
+   # draw a star with size and color
+   star(x,y,size, color_index)
+
+# hide so we have a nice drawing
+dan.hideturtle()
+```
+
+
+## Experiments
+1. Can you create a variable for the number of circles to draw?
+2. Go to the [Trinket colors page](https://trinket.io/docs/colors) and see the name of other colors you can use.  Note that you can use any of these colors in your lists.

+## Changing background and using keys to move the rocket
+
+We can use trinkets to change the background and change the shape of the turtle with a custom image.
+Also we can control the screen with the mouse. It gives a starting point for how to create a game.
+
+The following blog lays out the steps for creating a rocket ship
+https://blog.trinket.io/using-images-in-turtle-programs/
+
+
+The images have to be the same size as the the screen size. Here are some other images that have been resized.
+
+#Background
+![Night Sky matching screen size](../img/night_sky.png)
+
+#Rocketpanda
+![Rocket panda](../img/rocketpanda.png)
+
+## Sample Program
+[Sample](https://trinket.io/library/trinkets/eacf1bc102)
+
+## Experiments
+1. Can you map another keyboard key to take some other actions like jump, draw a circle.
+2. Use different images and create backgrounds of your choice, like rocketpanda gliding through night sky
