The data from the electromagnet experiment suggest some relationships between a cause (the construction of the electromagnet) and an effect (the number of paperclips lifted).

Think about the differences between Magnets A, B, and C. Now, select a question that you could ask to help you understand how the construction of an electromagnet affects its strength.

1) What effect does increasing the number of wraps of wire have on the strength of the electromagnet?

2) Will the magnet pick up other objects?

3) Does the battery need to have energy left in it?

4) Why does the nail pick up paper clips?

Rock, Paper, Scissors

In this unit, you expanded your Python skills, and now you can really have some fun! In this lab, you are going to create a game that allows the user to play Rock, Paper, Scissors against the computer. If you aren’t familiar with this classic game, here’s how it works: two people (or a person and a computer!) each select either rock, paper, or scissors. The player who chooses the stronger object wins. Here is how the winner is determined:


Rock beats scissors because a rock can break scissors.

Paper beats rock because paper can cover a rock.

Scissors beats paper because scissors can cut paper.

Go to https://repl.it/ to write your program.


Your program should do the following:


Randomly choose rock, paper, or scissors for the computer

Ask the user to choose rock, paper, or scissors

Compare the computer’s choice to the player’s choice

Announce whether the computer or the human won

Here are two hints to help you write this program:


Test parts of your program to see if they work before moving on to work on other parts. For example, you will need to have the computer select a random number and then choose for that number to correspond to rock, paper, or scissors. You can write just that portion of the program and then test it by having the program print the word “rock,” “paper,” or “scissors” before you even begin working on the part of the program where the user inputs their choice. (Of course, don’t forget to erase the line of code that prints the computer’s choice when you are finished testing—otherwise the game will be just a bit too easy for the user!)

On a piece of paper, draw a chart that shows all nine possible outcomes of the game and use that chart to design and test the program. The chart might look like this:

TABLE 1 Rock paper scissors outcomes

Computer chooses rock Computer chooses paper Computer chooses scissors

User chooses rock


Tied game


Computer wins


User wins


User chooses paper



User chooses scissors



Run several tests on your program to be sure that the correct winner is announced.


When your program works properly, take a screenshot of your code to turn in.

Compared to a ball with a mass of 10 grams, which statement describes the change in kinetic energy of a ball with a mass of 20 grams thrown at the same speed?


1) The kinetic energy of the 20 gram ball is the same as (=) the kinetic energy of the 10 gram ball.

2) The kinetic energy of the 20 gram ball is half (½×) the kinetic energy of the 10 gram ball.


3) The kinetic energy of the 20 gram ball is four times (4×) the kinetic energy of the 10 gram ball.


4) The kinetic energy of the 20 gram ball is two times (2×) the kinetic energy of the 10 gram ball.

Compared to a ball thrown at 10 meters per second, which statement describes the change in kinetic energy of a ball of the same mass thrown at 20 meters per second?



1) The kinetic energy of the ball thrown at 20 meters per second is half (½×) the kinetic energy of the ball thrown at 10 meters per second.


2) The kinetic energy of the ball thrown at 20 meters per second is two times (2×) the kinetic energy of the ball thrown at 10 meters per second.


3) The kinetic energy of the ball thrown at 20 meters per second is the same as (=) the kinetic energy of the ball thrown at 10 meters per second.


4) The kinetic energy of the ball thrown at 20 meters per second is four times (4×) the kinetic energy of the ball thrown at 10 meters per second.
