Scratch 101: If I Designed Monopoly...

Hello and welcome to Scratch 101! In this tutorial we will be learning to use the graphic paint editor (vector mode) by developing our own monopoly sprites. 

To learn how to use the paint editor effectively. 

Final Project:
Your student-made Monopoly cards! :)

Graphical Setup:
The graphical template is located here:

Activity 1 (Editing the Title):
Highlight the "text" symbol and click on the "Title Deed" statement. 
Activity 2 (Adding a Description):
Highlight the "text" symbol and click on an area where you wish to add the description. Click somewhere outside the text box to change the size of the text box. 
Activity 3 (Adding an Image)
Find an image which you would like to add to the card and download it to the computer. Use the "important button" to bring the file into your editor. Work around with the dimensions to finish the card.
Once you are finished with the activities you may:
  • Create another card
  • Create a script to randomly generate cards when you hit the space key. 
  • Add more features, images, or options to your card
  • Create another project with "custom sprites" (self-made) using the "Create a story" tutorial scripts available in the tutorial bar (you can see how to access that below). 

The Lewis Dot Structure for NH4+

Created by MakeTheBrainHappy
The Lewis Dot Structure for NH4+ (Ammonium) is shown above. These kinds of structures can also be shown by representing each of the bonds with two dots. Each atom in the bond has a full valence shell, with nitrogen having access to eight electrons and each hydrogen having access to two (this is why hydrogen only needs two). The covalent bonds between the N and the H are similar to the ones formed between two Hs because the relatively small difference in electronegativity between carbon and hydrogen. The whole structure is a cation due to the fact that Nitrogen is missing an electron. Neutral Nitrogen atoms have five valence electrons which are a part of the original structure, while this central atom has four. Therefore it has a +1 charge.

Ammonium is a tetrahedron structure in 3D space similar to methaneSource
The positively charged cation allows ammonium to act as a weak acid and occasionally revert to its original form (NH3 = Ammonia). NH4+ takes up a tetrahedral shape (as shown above) due to the fact that there are no lone pairs on the central atom. It is an important source of nitrogen for certain types of plant species.


Ammonium is known for forming different kinds of salts which would be classified as ionic compounds. In the image above, there are two salts shown which involve the ammonium ion. These are Ammonium carbonate and Ammonium sulphate.
