Here is one with IF and WHILE:

1. draw a box
2. put a turtle inside, set random heading
3. move the turtle forward until it reaches a box's side
4. then the turtle bounces like a ball and continues to move
5. stop after 5 bounces

Another one with WHILE:

1. two turtles are on a circle and move along it with different speeds
2. animate the chase until one of the turtle reaches the other

Another one with IF:

1. draw the snowflake fractal
2. but when you draw recursively, draw either to the left of the current 
segment, or to the right

Another one with WHILE and IF:

1. Use a turtle and the Monte-Carlo method to calculate pi with given 

With IF:

1. draw a Pythagorean tree until branches become smaller than 1 pixel
