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:
Use your
digital camera
to record your
results!
• Aim
• Hypothesis
• Equipment or Apparatus
• Steps
• Results
• Conclusion
Develop your hypothesis!
What do you think will happen?
Conduct your experiment!
1.
Equipment or
Apparatus
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.
•
600ml plastic bottle
• White vinegar
• Bicarbonate of soda
• Balloons
• A teaspoon
• A funnel
• Digital camera
What happened?
What did you observe and record?

Chemical Sciences- Science Understanding
Content Description
Solids, 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

Declarative Knowledge
Procedural Knowledge
The learner will know that
Gases have mass
Observations are made to collect and
analyse data
Solids, gases and liquids change under
different conditions
Not all substances can be accurately
classified based on their appearance
The learner will be able to
Observe and display that gases have
mass
Develop and attempt to prove a
hypothesis
Collect and analyse data
Observe and understand the change in
substances when put under certain
conditions
To test substances to investigate
