Fizzy BalloonsInvestigating

gases!Chemical Sciences Year 5

The aim of this investigation is to explore the

chemical effects of bicarbonate of soda and vinegar

when they are combined!

To inform others of your findings you must CREATE a

Scientific Report.Please include:

• Aim• Hypothesis

• Equipment or Apparatus• Steps• Results • Conclusion

Use your

digital camera

to record your

results!

Develop your hypothesis!What do you

think will happen?

Conduct your experiment!1. Fill a plastic bottle half way up

with white vinegar.

2. Using a teaspoon and a funnel,

place 5 teaspoons of bicarbonate

of soda into the balloon.

3. Twist the top of the balloon to

ensure no bicarbonate of soda

escapes.

4. Stretch the top of the balloon

over the top of the plastic bottle.

Untwist the balloon and allow the

vinegar to fall into the vinegar.

5. Observe and record the reaction.

Equipment or Apparatus

• 600ml plastic bottle

• White vinegar

• Bicarbonate of soda

• Balloons

• A teaspoon

• A funnel

• Digital camera

What happened?

What did you observe and record?

Did the reaction prove or disprove your hypothesis?

*Record your observations and data into your scientific report.

Chemical Sciences- Science UnderstandingContent DescriptionSolids, liquids and gases have different observable properties and behave n different ways.

Elaborations• Observing that gases have mass and take up space,

demonstrated by using balloons or bubbles• Exploring the way solids, liquids and gases change under

different situations such as heating and cooling• Recognising that not all substances can be easily

classified on the basis of their observable properties
