Take a look at the example and consider the following questions:

  • What should I do?
  • What are the goals?
  • What are the expectations?
  • What can I already do?
  • What do I still have to discover?


View the steps at 'perform'. Then answer the following questions:

  • Which steps should I follow?
  • Which steps can I follow?
  • How much time do I need?
  • What tools do I need?


Do the steps one by one. Do you not remember how to do it? View the hints or download the solution.


Remove the cat (= sprite) from the playing field. Right-click on the cat and click on delete or click on the bin.


Add two new sprites from the library. Click on 'choose a sprite' and choose a sprite by clicking on it. Then click on 'OK'. Repeat these steps for the second sprite.

You can see at the top right which sprite you are programming. The code you write for one sprite does not apply to the other sprite. You can even write code just for your background!



Choose a new background for the playing field. Click on 'choose a background' and choose a new background by clicking on it


Now we return to our sprite. That is important because we are now going to program this sprite. Click on the icon of the sprite you want to program at the bottom right (= "have something done".)



Your sprite is not making a sound yet. For this we first have to add some blocks to our sprite. Click on the purple 'sound' category and test the following blocks:


Click on the white arrow and choose the sound you added in the previous step.

Select the block 'start sound'. Nothing happens yet when you click on the green flag. Add from the category 'events' 11this block: 12 . Stick this block to the block 'start sound'. Then click on the green flag. What is happening?


Now we are going to change the appearance of your sprite when you click on it. To do this, you first of all go to the "costumes" tab. Look closely at the image below. You right click on your sprite and choose "duplicate".

You can change one of the two sprites: change the color, make the sprite smaller or bigger ...



Make sure to change the sprite's appearance. Use the box 'switch costume to' from the category 'Looks'.

Make sure you have this code. You choose of course which sprite and which sounds to use:


What happens when you click on the green flag?

Add a 'forever' (=repeat) block to the code. You can find it in the 'Control' category.


Experiment with the following blocks:



Look back at the project you just made. Ask yourself the following questions:

  • Does the program work as I expected? Why / why not?
  • What works well?
  • What works less well?
  • How can I approach it differently?
