Hot, Hot Days and Science Fairs

Water Knowledge
  • Once we have an understanding of knowledge and concepts, we can make predictions about unfamiliar situations.
Jan 30th & Jan 31st - Lesson 4
  1. Heating up water!  (15 mins)
  2. Quiz yourself (20 mins)
  1. Science Fair: (25 mins)
    1. Feb 13/14th: Design deadline
    2. Feb 17/18th: Data collection deadline
    3. Feb 19/20: Data processing, conclusion and evaluation deadline
    4. Feb 21/24: Presentation materials deadline
    5. Feb 25/26: Refinement and ready for presenting
  1. How do I make a research question from a topic that interests me?
You only require a partner if you have a difficult investigation or you are collecting lots of data.
Content: Students will
  • Describe how thermal energy (heat) is transferred by conduction, convection, and radiation, and how heat conduction differs in conductors and insulators.
  • Explain how thermal energy is transferred throughout the water cycle by the processes of convection, conduction, and radiation
Skills:
  • To categorize examples.
  • Study Skills:
    • To use question and answers to prepare for a test








      At the beginning of the class, we checked on the water purification experience we made the other class. We've seen that our experiment didn't work as well as the other class' because our container didn't have enough depth for the evaporated water to fall off the plastic where the rock was placed.
      Also, we tried a different way to create clean water by using electricity to heat up a container where the evaporated water would go through a plastic tube, and finally get to another container purified. Unfortunately, the hot water got some taste from the plastic, and wasn't that pleasant to drink. 

Next...
      We watched a quick video that shows someone with a mug full of boiled water(90 degrees Celsius) outside(with the temperature of -30 degrees Celsius). Then, he throws the water into the air, and it automatically turns into a gas, then snow. That happened because the viscosity of the water was lower because the water was hotter, then the water spread into the air when it was thrown. Next, it immediately lost its heat, and became a gas. Finally, it froze and became snow immediately after becoming an gas.

Then...
      We had the task to define how things/water transfers heat. Either being through radiation, conduction, or convection. 

After...
      We watched an Bill Nye video about transferring heat which we've done the task on.

Next...
      We went on to Quizlet to study some for the test. On this task, we developed the skill of studying and staying focused and on task. 

Finally...
      We proposed a question for the science fair.

  1. Hi Mari, I really liked your post since it is very neat and easy to understand. I really enjoyed the pictures since they have a high resolution (which makes it easier to se them) and helps us better understand the experiment's procedure.

    On the other hand, I wouldn't have added so many links. Instead, I would select the most important information on each link and summarize it. Overall, your post is great!

    1. In addition, your post has too much written information. You should try to improve your summarizing skills. Furthermore, you have just stated things we've done without giving any explanations or examples. For instance, when you said, "After... We watched an Bill Nye video about transferring heat which *we've done the task on.* " What task? You should have taken a picture of the task or explained it so people who didn't come to school on that day will be able to do it at home.
