lab Intro

Hurumanu - Science Laboratory introduction

Aim: To learn about the expected behaviour in a science laboratory.


Our R9 Class Treaty
  1.    bags under your desk 
  2.    no food and drink
  3.   no running
  4.   don't touch experiments
  5.  report any breakage or spills
  6.   do not taste or sniff anything
Safety in a laboratory.

teacher   shoes   practical  teacher laboratory   ask  sniff teacher  breakages

  2.   You must not enter the laboratory without your shoes.
  3.   Report all accidents to your teacher.

In your group, discuss how the following scenarios could be dangerous.
  1. Not putting your bag under your desk.  someone can trip
  2. Running around in the laboratory. someone can trip
  3. Not wearing shoes in a laboratory. you can stub your tow
  4. Shaking a test tube with your thumb over its mouth? chemicals could harm your skin
How do we work in this laboratory?
  1. Beginning and End of class: Lining up, Entry, Seating, 
  2. Equipment tray: equipment list and details.
  • Test tube - This is used for experiments using liquids. They have a bung that can be placed in the top. Test tubes sit in a test tube rack.Image result for test tubeConical Flask - This is used for experiments with liquid up to 150 ml. The flask has a rubber bung for the top and the glass is heatproof.Image result for Conical Flask
  • Glass Stirring rod - This is a 20cm glass rod used to stir and mix any liquids together.Image result for Glass Stirring rod
  • Test tube tongs - These are used to hold a hot test tube after an experiment.
  • Image result for Test tube tongsSpatula - This is for holding very small amounts of chemical powders.

AIM: TO LEARN ABOUT WATER ON EARTH.

Scientific words:

  • Evaporation. When water is heated by radiant energy it turns into water vapor.
  • Transpiration. Evaporation from plants.
  • Condensation. When water vapor cools, molecules join together and form clouds.
  • Precipitation. When clouds get heavy the waters falls as rain, sleet, hail, or snow.
  • Acidification: the action or process of making or becoming acidic.

THE WATER CYCLE EXPERIMENT

Bag 1: Normal Water cycle
Bag 2: Water cycle with CO2 added: like Oceans in climate change
Bag 3: Water cycle with ice added: like Antarctica in climate change

Material:

  1. plastic bag
  2.  water
  3. litmus paper 
  4. baking soda

Steps

Bag 1
  1. Get a ziplock bag and a vivid pen
  2. Draw the water cycle (label the parts of the water cycle)
  3. Carefully pour 1 cup of cold water
  4. Carefully drop 2 drops of blue food colouring
  5. Stick the ziplock bag in a window where it receives sunlight.

Bag 2
  1. Get a ziplock bag and a vivid pen
  2. Draw the water cycle
  3. Carefully pour 1 cup of cold water
  4. Carefully drop 2 drops of blue food colouring
  5. Carefully put 1 teaspoon of baking soda
  6. Stick the ziplock bag in a window where it receives sunlight

Findings:





The Water Cycle: Bag 1

Amount of Water
32
Acidity
02

Key: Water and acidity amount: 1 = none 
2 = small 
3 = large

Conclusion:

what I learned is new words evaporation condensation and transpiration



    ACIDIFICATION

    DEFINITION:

    ACIDIFICATION: HOW DOES CLIMATE CHANGE CONTRIBUTE TO THE ACIDIFICATION OF OUR OCEANS?









    DEFINITION:

    DEFORESTATION: HOW DOES DEFORESTATION AFFECT CLIMATE CHANGE?







    ICECAP MELT


    DEFINITION:

    ICECAP MELT: HOW DOES ICECAP MELT AFFECT CLIMATE CHANGE?




    WATER VAPOUR

    DEFINITION:

    WATER VAPOUR: HOW DOES  WATER VAPOUR AND EVAPORATION CONTRIBUTE TO CLIMATE CHANGE?

     Hi, guys today we were talking about self-management. In this topic, We talked about how we can manage our learning. She told us to get into a group of two and make a DLO. Something I did that shows that I am a self-manager is I was organized with all my things at the right time. What can I do to be a better self-manager? I can sit alone. Here is our DLO.
