The document provides instructions for making bath fizzers. It lists the ingredients needed, which include citric acid, sodium hydrogen carbonate, and herbs or essential oils. The instructions state to combine the citric acid and sodium hydrogen carbonate in a plastic bag, add water and herbs/oils, then squeeze the bag until a ball forms. It recommends using cellophane and raffia to wrap the fizzer and labeling it with safety information and ingredients.

bath fizzers
Hayley Sherrard and Teresa McErlean

2. The ingredients and equipment needed for one
bath fizzer are:
•
•
•
•
•
•
•
Citric acid (3 spoonfuls)
Sodium hydrogen carbonate (3
spoonfuls)
Plant sprayer filled with water
(sprayer should not have
previously contained any harmful
substances)
Plastic bag
Teaspoon of dried herbs or
essence e.g. mint, lavender
flowers, rose petals, lemon or
vanilla.
Packaging materials cellophane/tissue paper/ribbon
Label / gift tag

3. Instructions
Put 3 spoonfuls of citric acid and 3 spoonfuls of
sodium hydrogen carbonate into the plastic
bag.
Add a teaspoon of your chosen herbs or
essence.
Spray 3 small sprays of water into the bag and
squeeze to combine ingredients. Continue
squeezing bag until ball shape formed. Add
water in very small amounts if necessary.

10. Glowmeet
Sound - 21st & 22nd January 2014
In need of sound advice? Then this Glow Meet is for you.
Explore a range of easily made instruments which will enthuse and engage pupils as
they study the topic of sound. Get ideas to help in the teaching of concepts
surrounding sound. Focusing on line of development 11, this workshop will
demonstrate activities suitable in Early, First and Second Levels.

11. Good activity?
Good science?

12. • What do you see?
• Is there anything you can think of
that is similar?
• What is happening?

13. Carbon dioxide is produced through the
reaction between an acid and
bicarbonate of soda (sodium hydrogen
carbonate).

15. • Through exploring properties and sources of
materials, I can choose appropriate materials to solve
practical challenges. SCN 1-15a
• By contributing to investigations into familiar changes
in substances to produce other substances, I can
describe how their characteristics have changed.
SCN 2-15a
•
I have collaborated in activities which safely
demonstrate simple chemical reactions using everyday
chemicals. I can show an appreciation of a chemical
reaction as being a change in which different
materials are made. SCN 2-19a

16. • Children and young people are not often
enough experiencing sufficient depth in their
learning across all key areas in the sciences.
One contributing factor is insufficient
awareness of Sciences: Concept development
in the sciences (2009) paper.
(The Sciences 3-18, Education Scotland)

17. The big ideas of science – Lines of Development
Based on Concept Development in the Sciences
• 15 – Learners develop their understanding
of the connection between the structure
and properties of materials
• 19 – Learners develop an understanding of
chemical reactions

18. Further activities
• Make a fire extinguisher.
• Make a lava lamp.

19. Use cellophane and the rafia provided to
wrap your bath fizzer

20. Write an advice and instruction label.
• Remember to include the following
information:• The bath fizzer should not be eaten.
• Not suitable for small children.
• List the ingredients.
• When ready for use it should be placed into a
bath where it will fizz!
• Add your name to the label.
