Module 6: Quiz

1. Jane created a list called {"type":"wrapper","func":"valueList","name":"WeekDays"} and added the values ["Sunday", "Monday" "Tuesday"] into it. Then she used this block to add another item:
{"func":"blockListInsert","values":[{"type":"string","value":"Wednesday"},{"type":"choice","value":"1"},{"type":"string","value":"WeekDays"}]}
What are the values in the list?

  • ["Wednesday", "Sunday", "Monday", "Tuesday"]
  • ["Sunday", "Wednesday", "Monday", "Tuesday"]
  • ["Sunday", "Monday", "Wednesday", "Tuesday"]
  • ["Sunday", "Monday", "Tuesday", "Wednesday"]

2. What is the difference between
{"func":"blockListAdd","values":[{"type":"string","value":"Power Cell"},{"type":"string","value":"Items"}]}
and
{"func":"blockListInsert","values":[{"type":"string","value":"Power Cell"},{"type":"choice","value":"1"},{"type":"string","value":"Items"}]}

  • Both blocks add the item to the beginning of the list.
  • The add block puts the Power Cell at the beginning of the list.
  • The insert block puts the Power cell at the beginning of the list.
  • None of the other choices are correct.

3. What is the difference between
{"func":"blockListAdd","values":[{"type":"string","value":"Power Cell"},{"type":"string","value":"Items"}]}
and
{"func":"blockListInsert","values":[{"type":"string","value":"Power Cell"},{"type":"choice","value":"last"},{"type":"string","value":"Items"}]}

  • Both blocks perform the same action.
  • The add block puts the Power Cell at the beginning of the list.
  • The insert block puts the Power Cell at the beginning of the list.
  • None of the other options are correct.

4. How do you count the number of items in a list?

  • {"type":"wrapper","func":"valueListLength","values":[{"type":"string","value":""}]}
  • {"type":"wrapper","func":"valueOpLength","values":[{"type":"string","value":""}]}
  • {"type":"wrapper","func":"valueSensingNumActors"}
  • None of the other choices are correct.

5. Mark has a list with an odd number of entries. Which of these code blocks will access item in the middle?

6. How do you delete all items in a list?

  • You cannot delete all the items in a list using a single command.
  • {"func":"blockListDel","values":[{"type":"choice","value":"all"},{"type":"string","value":""}]}
  • {"func":"blockControlDeleteActor"}
  • {"func":"blockListDel","values":[{"type":"choice","value":"any"},{"type":"string","value":""}]}

7. The list "Inventory" contains the following items: 2 Power Cells, 1 Health Kits and 2 Armors. What does will this code display?
{"func":"blockLooksSay","values":[{"type":"wrapper","func":"valueListLength","values":[{"type":"string","value":"Inventory"}]}]}

  • 2 Power Cells, 1 Health Kit, 2 Armors
  • Power Cell, Power Cell, Health Kit, Armor, Armor
  • 5

  • {"func":"blockListAdd","values":[{"type":"wrapper","func":"valueListItem","values":[{"type":"choice","value":"1"},{"type":"string","value":"List1"}]},{"type":"string","value":"List2"}]}

9. What are the contents of the list Numbers after the following code is executed? Assume the list is empty. {"func":"blockListAdd","values":[{"type":"string","value":"100"},{"type":"string","value":"200"},{"type":"string","value":"300"},{"type":"string","value":"Numbers"}]}

  • ["100","200","300"]
  • ["200","300","100"]
  • ["300","200","100"]
  • ["300","100","200"]

10. Suppose you add an item to a list using the {"func":"blockListAdd","values":[{"type":"string","value":"item"},{"type":"string","value":"List"}]} block. Where does the item go in the list?

  • End of the list
  • Beginning of the list
  • Middle of the list
  • You have to specify the location.

11. Suppose we have a list called Inventory. Which block do we use to access the 5th item of the list?

  • {"type":"wrapper","func":"valueListItem","values":[{"type":"choice","value":"5"},{"type":"string","value":"Inventory"}]}
  • {"type":"wrapper","func":"valueListLength","values":[{"type":"string","value":"Inventory"}]}
  • {"type":"wrapper","func":"valueLooksSize"}
  • {"func":"blockAnimationSimpleSwitchCostume","values":[{"type":"string","value":""}]}

12. True or False: You can delete all items in a list with one delete block.

  • True
  • False

13. What will this script do?
{"func":"blockVarSet","values":[{"type":"string","value":"i"},{"type":"string","value":"0"}],"next":{"func":"blockVarSet","values":[{"type":"string","value":"a"},{"type":"string","value":"0"}],"next":{"func":"blockControlWhile","values":[{"type":"wrapper","func":"valueOpLess","values":[{"type":"wrapper","func":"valueVar","name":"i"},{"type":"wrapper","func":"valueListLength","values":[{"type":"string","value":"Items"}]}]}],"containers":[{"func":"blockControlIf","values":[{"type":"wrapper","func":"valueOpEqual","values":[{"type":"wrapper","func":"valueObjGet","values":[{"type":"wrapper","func":"valueList","name":"Items"},{"type":"wrapper","func":"valueVar","name":"i"}]},{"type":"string","value":"Power Cell"}]}],"containers":[{"func":"blockVarChangeBy","values":[{"type":"string","value":"a"},{"type":"number","value":"1"}]}],"next":{"func":"blockVarChangeBy","values":[{"type":"string","value":"i"},{"type":"number","value":"1"}]}}],"next":{"func":"blockLooksSayFor","values":[{"type":"wrapper","func":"valueVar","name":"a"},{"type":"number","value":"2"}]}}}}

  • Count the number of objects in the list "Items" and say it.
  • Count the number of Power Cell objects in the list "Items" and say it.
  • If the last item in the list is a Power Cell, it will be missed in the count.
  • Change all the Power Cell objects in the list by 1.

Key stage 3
Pupils should be taught to:
  • design, use and evaluate computational abstractions that model the state and behaviour of real-world problems and physical systems
  • understand several key algorithms that reflect computational thinking [for example, ones for sorting and searching]; use logical reasoning to compare the utility of alternative algorithms for the same problem
  • undertake creative projects that involve selecting, using, and combining multiple applications, preferably across a range of devices, to achieve challenging goals, including collecting and analysing data and meeting the needs of known users
  • create, reuse, revise and repurpose digital artefacts for a given audience, with attention to trustworthiness, design and usability
  • understand a range of ways to use technology safely, respectfully, responsibly and securely, including protecting their online identity and privacy; recognise inappropriate content, contact and conduct, and know how to report concerns
Key stage 4
All pupils must have the opportunity to study aspects of information technology and computer science at sufficient depth to allow them to progress to higher levels of study or to a professional career. Pupils should be taught to:
  • develop their capability, creativity and knowledge in computer science, digital media and information technology
  • develop and apply their analytic, problem-solving, design, and computational thinking skills
  • understand how changes in technology affect safety, including new ways to protect their online privacy and identity, and how to report a range of concerns

  • Quiz

Description

In this advanced lesson plan, students will be introduced to the physics library as they build Gravity Sling, a projectile game inspired by Angry Birds (TM). They define the behaviors of different kinds of projectiles and use physics commands such as impulse, gravity and collisions to build the game. Ninja Runner is an advanced physics platformer game with a boss fight sequence that challenges them to apply all the concepts and skills they have learned.

Students who successfully complete this lesson plan will demonstrate excellent understanding of a variety of programming concepts and computational thinking skills, and will be able to design and implement projects of moderate to advanced complexity.
