Write a program in which the use is asked to guess the weight of an animal. Allow the user 5 guesses to figure the weight of the animal.
Finished Project :
loop to keep track of the number of guesses and and the world function
One of the hardest concepts for younger programmers to learn is what returning a value means, a concept which Alice represents by its notion of ‘functions’. And, in Alice, a great approach is to require students to move an object based on the distance and to use a function to return the value of that distance and store it in a variable.
Every object in Alice has a set of proximity functions:
However, distance to, which most students will probably be most tempted to use is rarely what you want to use–especially when you want to move an object relative to another object using the calculated distance.
Consider, the picture below. Let’s say we want to calculate the distance between the hammer and the moon’s surface. Well, if you used distance to to calculate the distance and move the hammer down, you’ll see that the hammer actually falls down into the moon. That’ s because the distance is being calculated from the center of the hammer and the center of the whole planet!
Instead, use distance above!
In the picture below, if you want the astronaut to move to the spaceship based off of a distance, you should try the distance in front of
Before you jump into text coding with middle school coders , Alice is a powerful tool for teaching what “returning a value” means.
Alice Supports Several Boolean Logic types. They exist under the world functions :
We are going to create a Rock, Paper, Scissors game using Alice loops and if/else ‘s
3.Add a while loop based on gamePlaying
4. Make a variable called cpuChoice. cpuChoice is a number This variable will represent what the computer randomly chooses (rock, paper or scissors)
5. Use the world function that generates a random number so that the random number is an integer between 1 and 3 , inclusive.
Store the return value of that random number generator into cpuChoice at the beginning of the loop
6. Debugging has many meanings. Experienced developers build debugging and logging into the development of their programs from the start.
7. Right click on cpuChoice and select watch this variable
8 .Now we have the computer randomly choosing either 1,2, or 3 and these numbers will represent rock, paper and scissors respectively
Alice Supports many types of Math Operations.
For instance, let’s say that we have the variable someNumber and it has a value of 2
2) select “2*” which means “2 times ”
3) Select “Other” for the second number “b”
4) The calculator appears so you can choose 5
5) Select “5”
6) Viola: You know have a math expression that represents 2 * 5
8) Now let’s make a variable called “divisor” and then divide this expression by that
9) Select the down arrow
10) select as shown:
11) Viola :
The world object has many, many useful functions including a way to ask the user for information—say a number, a name or something.

Animated Gif showing the whole process of asking user for a number and then saying that number (using what as a String)
FIRST: make sure you know: how to use What as a String and perform Math expressions . You will not be able to do this assignment until you understand both of the above lessons.

Create a world that has a character (person/penguin/whatever) that will ask the user for the height of a triangle and the base of a triangle, and calculate its area
Objective : to let the user type in a number between 1 and 10 and then have a character “translate” that into Roman Numerals ( I, II, III, IV, V, VI, VII, VIII, IX, X)
Final result :
We are going to use the roman Numeral Translator file again, so it’s important that you don’t lose the file and give it a good name that you can easily recognize in the future.
Extra credit: Translate 1-20 (Note : You still need to display an error if they enter a number that is too big, which in this case would be >21)

Assignment 5-extra credit ). Look up the formulas for the volume and surface area of a cylinder . Ask the user for the height of the cylinder and the radius, which should be stored in variables. Then calculate the surface area and volume of the cylinder . See if there is a cylinder shape in the gallery to use as a visual aid. And have an object say the volume and surface areas.
During the Apollo 15 mission to the moon, astronaut David Scott performed an experiment to prove that Galileo was right when he said that any two objects dropped at the same time would land on the ground at the same time in the absence of air. Scott, standing on the surface of the moon, dropped a hammer and a feather and indeed both objects hit the ground simultaneously.(Again, you must use “do together”)
Create an Alice world that recreates the experiment. You will find classes for the astronaut, lunar Lander, and the moon’s surface in the Web gallery’s Space collection. You can find a class for the Hammer in the Objects collection. Substitute any object of your choice for the feather.
Note : for following 3 steps, see Example 1 below
Example 1 (help with steps 2-4)
Steps 2-4 are similar to what is happening in the following picture :
Create a space world with an astronaut and two spaceships(from the Web gallery’s Space collection). One of the spaceships is stranded with engine trouble, and the astronaut has arrived in the other spaceship to perform a repair.

Programming Requirements
10 points of the following
5.1: Exercise Competition:
Three girls Jenny, Kelly, and Barb are enrolled in an exercise class. One day after class the three decide to have a friendly competition to see how many sets of 10 repetitions of running in place each can do before getting tired. Barb decides to go first and gets tired at 10 repetitions. Kelly goes next and she gets tired at 20 repetitions. Jenny, who has been in the exercise class for the longest, goes next. She gets tired at 30 repetitions.
Create a world that suites the competition.
ExerciseGirl class that you created in chapter 5.
EACH Assignment below requires the use of a parameter in some way. If you do not have a parameter, as described, you will lose a lot of credit.
Here is a helpful link on how to create and use parameters, in case you forget.
Add a jumpingJack method to the ExerciseGirl class. The method should make the object perform jumping jacks .
Marcello the magician has finally mastered his disappearing act. To perform the act, he places several items on a table in front of him. He stands with his right arm extended over an item. He says the magic word “Alakazam, Alakazee” and the object disappears. He repeats this procedure for each object on the table. Create a world in which Marcello (an instance of the Magician class from the People Collection) demonstrates his new act . In the magician object
