  • It really is VERY important that you have already taken my course "Learn Scratch 2.0 for Kids".
  • You should have already installed Scratch 2.0 and know how to use it (ie taken my other course).
  • screen sizes 1024 x 768 or larger
  • (Chrome 7 or later, Firefox 4 or later, or Internet Explorer 7 or later) with Adobe Flash Player version 10.2 or later installed

M.I.T. created Scratch 2.0 to be a programming language for kids aged 8-17.

This course, Create the Game Asteroids Using Scratch 2.0 will teach your kids how to create a once popular game in Scratch. It will take things slow by showing specific examples that they can recreate for themselves. Scratch 2.0 is a beginning level programming language course that anyone can take and learn. While there is no "real" coding involved it does teach the basics of what is needed in a "real" programming language. Plus it is a good foundation for those who want to learn to program for the mobile phones.

The terminology in this course would be similar to what students would find in their normal coursework.

No materials are included or needed except for the software which you can download for free.

While this course could easily be finished in a week, this course should be taken over at least a month to get the most out of it. It is expected that you should try to replicate everything you have learned in the lectures plus do all the quizzes. It is also expected that you should experiment. Try your own programs using what you just learned.

While this course is mainly for kids 8-17, anyone can take this course. This course would also be good for stay at home moms as well as grandparents who want to stay involved with their grand-kids.

The course is structured as a series of videos explaining how to think about making your game.

Why should you take this course? That is an excellent question and there are many reasons.

Computer Programming is one of the only jobs you can get a high salary in without going to college. In fact many businesses would rather have a high school student with many years experience than a graduate student with a Masters or PhD in Computer Science but little practical experience. Many of the big names like Bill Gates and Steve Jobs dropped out of college and became famous for their programming skills.

Example: You can't be a Nuclear Engineer without going to college because you can't have your own personal nuclear power plant at home but you can be a computer programmer. Scratch is an excellent start at becoming a computer programmer because it introduces you to so many new concepts instead of trying to jump into the deep end of the lake.

Example: You will learn the dynamics of making a simple game. What do you do when a laser hits an asteroid or goes off screen? These are all basic things that every programmer needs to know and understand when making games. Scratch teaches these basic things and then from there they can go on to more robust languages.

So, if you want your child to get a good start at programming, then Scratch 2.0 is the right choice and what better way to learn a language than to create a game in it?

Who is the target audience?
  • This course is for ANYONE who completed my previous Course "Learn Scratch 2.0 for Kids".
  • Kids aged 8 or above.
  • Grandparents
  • Stay at Home Moms
  • This course is NOT for anyone with good programming experience. I go over every topic thoroughly (read slowly) so you will be bored if you are a good programmer.

Bullets and speed
3 Lectures 36:12

After this class students will be able to make a bullet fly across the screen.  After they do the homework they will understand how speed affects the bullet and the target.

Bullets and Speed

This will give the answers to the homework.  So, after this class they will understand how to calculate the maximum speed of the bullets for their game.

Bullets and Speed Homework

After this lecture they will know how to make bullets move and how it corresponds to the ship.

More Info About Bullets
7 Lectures 01:29:40

After the class the students will be able to create clones of bullets for their game and of other items.

Learning About Cloning

After this lecture students will understand properties of cloning like show/hide.  Then they will be able to create multiple copies of big asteroids. 

More About Cloning

After seeing the solutions they should now know how to create objects off screen as well as determining randomly where to place them.

Homework Solutions for Cloning of Big Asteroids

The student will learn how and why to delete clones.

1st Part of New Homework for Deleting Clones

The student will learn how to create new smaller asteroids when their larger asteroid is destroyed.  If it is the small asteroid then delete entirely,

2nd Part of New Homework for Creating New Clones

The student will learn how messaging works and how it can be used for deleting clones.

Deleting Clones Using Messaging

Here the student will learn how to go through the program to see where the bugs are.
