AHDS2013 WS 5 Science in primary school

  1. 1. Making bath fizzers Hayley Sherrard and Teresa McErlean
  2. 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. 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.
  4. 4. SSERC Scottish Schools Education Research Centre What can SSERC do for you?
  5. 5. Science and Technology related Health & Safety for schools
  6. 6. Science & Technology Bulletin
  7. 7. Web-based resources
  8. 8. CPD
  9. 9. NQT/Probationer Course “All workshops were very insightful and provided practical, useful, simple and quick ideas that I can implement in the classroom ... starting Monday.” 31st Jan-1st Feb 2014 & 12th May 2014
  10. 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. 11. Good activity? Good science?
  12. 12. • What do you see? • Is there anything you can think of that is similar? • What is happening?
  13. 13. Carbon dioxide is produced through the reaction between an acid and bicarbonate of soda (sodium hydrogen carbonate).
  14. 14. Curriculum for Excellence Materials Properties and uses substances. Chemical changes •line of development 15 • line of development 19
  15. 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. 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. 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. 18. Further activities • Make a fire extinguisher. • Make a lava lamp.
  19. 19. Use cellophane and the rafia provided to wrap your bath fizzer
  20. 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.
  21. 21. Contact information
