Transcript
Animations are all about making pictures come to life. Let's get into Scratch and make it happen. I've programmed the cat to move using the steps command and the wait command. Using the wait command makes it look more realistic because the cat is pausing between each of the steps rather than just gliding along the screen. But my code is already getting quite long. If I wanted to make my animation longer, then it would soon become hard to keep track of what was going on. This is where the repeat tool comes in handy. I can take away my repeated commands, then go into control and use the repeats to tell the program how many times I want it to repeat that command before stopping. The cat is now following the same instructions, but my code is much shorter. Head over to scratch.mit.edu and have a go yourself.

Sample Questions
Here are some example of questions about this video that kids may be asked in the 1Question app to earn screen time:

How does using the 'wait' command make the cat's movement more realistic?
It makes it look like the cat is taking steps rather than gliding across the screen
It makes the cat's legs move
It doesn't do anything It pauses the animation

How does the 'repeat' tool make coding easier?
You don't have to use the same coding blocks over and over again
It writes the code for you
It makes the code work faster
It makes the code longer

Why might having a long sequence of code cause a problem?
It is difficult to keep track of the commands and spot bugs in the program
There isn't enough space on the screen
The computer can't follow too many instructions
The code will get mixed up

About 1Question
► 1Question was created by parents for parents, knowing that the average child (8-12 years) spends around 4 hours a day on screens. With the 1Question app, kids earn recreational screen time by learning. Much like sneaking vegetables into a cake, 1Question is sneaking micro-learning moments into your child’s screen time. Our award-winning app gives parents control over screen time by setting a study-to-playtime ratio and delivering Micro-Courses to kids. This video lesson is one from a science Micro-course available in the 1Question App.
