Scratch Q4-ICT Grade 4

What Scratch block makes a sprite move forward?

• A) turn (15) degrees
  

• B) move (10) steps
  

• C) if on edge, bounce
  

• D) set [score] to (20)

Which block helps the fish change its direction randomly?

• turn (pick random -30 to 30) degrees

• (pick random -30 to 30) degrees

• turn (pick random -30 to 30)

• degrees

Arrange these steps in the correct order to create a randomly moving fish:

1️⃣ forever loop
2️⃣ move (10) steps
3️⃣ turn (pick random -30 to 30) degrees
4️⃣ if on edge, bounce

• Correct Order: 4 → 2 → 3 → 1

• Correct Order: 1 → 3→ 2→ 4

• Correct Order: 1 → 2 → 3 → 4

• Correct Order: 3 → 2 → 1 → 4

A sprite clone is a copy of the original sprite that can have its own actions.

• True

• False

Arrange these steps in the correct order to increase the score when the fish touches the shark:

1️⃣ if <touching [Shark] ?> then
2️⃣ forever loop
3️⃣ change [score] by (2)

• 1 → 2 → 3

• 2 → 1 → 3

• 3 → 1 → 2

Arrange these steps in the correct order to make a timer that decreases every second:

1️⃣ change [Timer] by (-1)
2️⃣ repeat until <(Timer) = 0>
3️⃣ set [Timer] to (60)
4️⃣ wait (1) second

• 3 → 2 → 4 → 1

• 3 → 1 → 4 → 2

• 1→ 2 → 4 → 3

The touching [Shark] ? block can only detect contact with the shark sprite.

• True

• False

Which loop should we use to keep the fish moving forever?

• B) forever
  

• A) repeat (10)
  

• C) wait (1) second
  

• D) stop all

Arrange these steps in the correct order to make the fish move randomly:

1️⃣ move (10) steps
2️⃣ if on edge, bounce
3️⃣ forever loop
4️⃣ turn (pick random -30 to 30) degrees

• 3 → 1 → 4 → 2

• 4→ 1 → 1 → 2

• 1 → 2→ 4 → 3

• 1→ 2 → 4 → 3

Arrange these steps in the correct order to reduce the score when the fish touches the shark:

1️⃣ change [score] by (-1)
2️⃣ forever loop
3️⃣ if <touching [Shark] ?> then

• 2 → 3 → 1

• 1→ 3 → 2

• 2 → 1→ 3
