Unit 10 Electricity and Information - Lesson 2 Logic gates

This lesson is all about logic gates.  There are millions of these in a computer processor and they are used to make decisions.

Your work
1.  Watch the video
2.  Open Activity 1 worksheet and go to File - Make a copy.  Answer the questions on your copy of this worksheet.  Share it with me and Mr Surrall and paste the link onto your Blog post for this lesson.
3.  Open Activity 2 worksheet (in Activity 3 section!) and make a copy of it as before.  Answer the questions on your copy of this worksheet.  Share it with me and Mr Surrall and paste the link onto your Blog post for this lesson.
4.  Give your Blog post a title.
5.  Under the 2 pasted links, explain what logic gates are used for (see the teacher's presentation for hints).
6.  Publish your Blog post at the end of the lesson.

If you don't finish this work in the lesson, please make sure it is finished for homework ready for your next lesson

From looking at your work, some of you are struggling on the logic gates.  Hint:  AND gate - if one input is a 0, then output is always 0.  OR gate - if one input is a 1, then output is always 1 (one and OR begin with the same letter)
