  2. Who can save the most snow 1 ? L.O. To use our knowledge of energy transfers to preserve the greatest amount of snow possible in the laboratory. Aim. To research, carry out and evaluate the best method of keeping things cool. Starter In 5 minutes write down as many words as you can related to heat, temperature and energy.

  3. If we wish to keep something cool we have to stop energy transfer as heat. For each answer write the page number and book or FULL website you got the information from. There are 3 main forms of energy transfer. Decide on the best way of stopping Conduction Convection Radiation. From a normal plastic cup or beaker. Sources of information Sources of information p 104 – 111 of Science works 2. P24 – 29 of Spotlight Science. http://www.bbc.co.uk/schools/gcsebitesize/science/ocr_gateway/home_energy/ Research.

  4. List at least 3 sources of information that you have used with full weblinks or book and page number. Bibliography.

  5. Who can save the most snow 2 ? L.O. To insulate a beaker in the most effective manner to preserve 50g of snow or crushed iced. Starter 5 minutes In a group of 2 or 3 at most compare your answers from last lesson. Agree on a way of insulating your beaker effectively. Nothing can go inside the beaker. It may have a lid if you can attach it quickly. You may use any 3 pieces of the following. A paper towel, a piece of silver foil, a tissue, a piece of card, a heat proof mat, bubble wrap, a plastic lid, a circular section of rubber tube, 1 larger beaker, white paper, black paper, a spoon full of salt.

  6. Who can save the most snow 2 ? Prepare your snow preserver. You may use 1 elastic band and upto 50cm of masking tape. Your snow will arrive in 5 minutes. Your teacher must be able to quickly add the snow.

  7. Who can save the most snow 2 ? Leave the snow in the beaker for 15 minutes. While waiting each group should fill in their materials into the results table .

  8. ResultsRemove your beaker from it’s wrapping.Set up a measuring cylinder and funnel.Pour out the water and record the result in the table.

  9. Who can save the most snow 3 ? L.O. To analyse and evaluate our results. Starter Draw a bar chart with the group number and mass of snow melted.

  10. Is it what I expected. Was it what you expected to happen ? What did your research suggest. How could you make the experiment better, what could have made your experiment more accurate. What health and safety risks were there. If time allows draw a poster advising people how to preserve snow and ice this winter.

  11. Looking for patterns. Look at the 3 groups that melted the least of snow. Which materials did they use, were any used by 2 or 3 groups Look at the 3 groups that melted the most snow. Which materials did they use ? Were there any used by 2 or 3 groups. Conclusion Level 3 . The best insulating materials were….. Level 4. I know this because…….. Level 5/6 The reason for this is ……..
