Grade 6 Instructional text: Building a bottle rocket quiz

What is the first step in creating the mini bottle rocket?

• Use tape to attach 3 straws to the side of the bottle so it stands up, upside down.

• Wrap the baking soda up in the kitchen roll to make a little parcel.

• When you're ready to launch, drop the baking soda parcel into the bottle, quickly add the cork, put the rocket down and stand back!

According to the text, how much of vinegar should you pour into the bottle?

• 5cm

• 5ml

• 3ml

• 3cm

What should you do with the baking soda?

What is the purpose of the cork in the mini bottle rocket?

• The cork serves as a stopper, allowing the pressure inside the bottle to build up until it is released, which launches the rocket upward.

• The cork acts as a stopper that builds up pressure inside the bottle until it is released, propelling the rocket upward.

• The rocket ascends because the cork functions as a stopper, allowing pressure inside the bottle to build up until it is released.

• All of the above

Why is it important to choose a hard surface for the launch area?

Warning - make sure you have _____ empty space and keep observers well back from the launch site as the rocket shoots up very quickly.

You'll need:

Small 500ml bottle - empty

Cork which fits tightly inside the bottle neck

Half a piece of kitchen roll

1 tablespoon of _____ _____ - bicarbonate of soda

Vinegar or lemon juice

3 straws

Tape

What safety precautions should you take when launching the mini bottle rocket?

• Ensure there is a clear, empty space, keep observers well back from the launch site, and use a hard surface for the launch.

• Look up to see the launch of the rocket.

• Use a hard surface for the launch, make sure there is a clean, unoccupied area, and keep observers well back from the launch site.
  

• None of the above

How do the straws help in the construction of the mini bottle rocket?

• • The straws help the bottle stand upside down, providing stability and a clear launch direction.

• They add weight to the rocket.

• They are used to stir the vinegar and baking soda mixture.

• They decorate the rocket.

What might happen if you don't wrap the baking soda in the kitchen roll?

• The rocket will launch higher.

• The vinegar might spill out of the bottle.

• The reaction will happen too quickly, making the rocket less effective.

• The baking soda will not react with the vinegar.
