Who can do Computer Science

Guess who are the Computer Scientists in the following pictures:

What can you do with Computer Science

Problem Solving Learn how to build Algorithms. . . a sequence of steps/instructions to solve a problem Algorithm type Puzzle 1. l l you have a pair of scales you have 12 coins 11 weigh the same the other is heavier How do you find the heavy coin if you are allowed 3 weighings? . .

Programming a computer can only do what it is told to do l a program is a set of instructions telling a machine what to do. l programming involves learning how to write instructions that do specific tasks l l Programming is an important part of computer science …… l BUT COMPUTER SCIENCE IS SO MUCH MORE!

So What is Computer Science? We hope we have shown you that computer science can be many things …. and computer scientists can be many different types of people ……. including YOU!!

Puzzle 2. You come to a fork in the road and meet a twin and ask the way to go. One twin always tells the truth One twin always tells lies. How do you decide which way to go?

Puzzle 3. l Three children sit one behind the other in a row. The third child can see the first two, the second child can only see the first and the first child can't see either of the other two. l A teacher has a box of five hats, two red ones and three black ones. The teacher places a different hat on each of the three children. l She instructs each one to call out the color of their hat once they are sure of it. All of the children are perfectly logical. l Within a few minutes the first child correctly states the color of her hat. l What color is it?

Puzzle 4. There is a certain type of rope that when lit at one end, will take an hour to burn. The burning however is not uniform and so it might, for example, take ten minutes for the first half to burn and fifty minutes for the second half to burn. You have two such ropes, but they are not identical Your number of matches is not a concern. How can you measure exactly 45 minutes?

Answer puzzle 1. l l l split into 3 lots of 4 take the first 4 coins and weigh against second lot with one weighing you know if the heavy coin is in the 1 st or 2 nd group because the balance will go down … or if they stay balanced it's in the 3 rd group l now take your group of 4 coins and split into 2's now you can separate the pair and see which is the heavy coin. To make this a more difficult problem try finding the coin of different weight without knowing if it's heavier or lighter. . think about it. . .

Answer puzzle 2. You say to the twin "If I asked your twin which road to take what would she say? ". . and then you take the other road. . .

Answer Puzzle 3 l l l l Black. If the third child does not reply first then she must be confused by the hats of the other two. If the hats of the first two were red, then the third would know she had a black. The second child, hearing the silence of the third realizes that he and the first child can't both have red hats. If the first child has a red hat then the second child knows, since he cannot also have a red hat, that his hat is black. The first child, noticing the silence of the other two, realizes that she cannot have a red hat. Therefore, her hat must be black.

Answer Puzzle 4. You set the two ends of one rope and one end of the second rope on fire. Once the first rope has burned out a half hour has passed. By lighting the other end of the second rope at that time, it will take fifteen additional minutes for the second rope to completely burn out.
