As a follow-up to Uncle Chris’s presentation, the first graders observed how to plant the `ōhi`a lehua tree.  These two trees will represent the first graders and will be part of the project next year.  Yesterday, Uncle Chris returned and graciously brought an orange lehua tree for us to plant.  So now we will have an orange and a red `ōhi`a tree.  Also helping us was Uncle Kaimi who dug the holes and helped install the tree carefully.  Kumu Crabbe also shared his mana`o on the tree parts, chanted and provided a pule over the trees, students and the project.

I look forward to continuing this project next year as well as the years to come.  Mahalo to Chris Wong, Greg Ho, Kumu Kaleo, Kumu Littrell and Kumu Crabbe for all your support.

Iʻve been getting many questions regarding page 4 of the solar boat packet.  So Iʻve put together more information and resources on the blog.  On the top menu bar there is a section called “Solar Boat Resources”.  I have updated the sections on ʻenergy transferʻ and ʻenergy sourcesʻ. Please use it to help you.

Also, click HERE for another great visual resource.  It is an illustration summary of energy. It has cool graphics, information, diagrams that you can interact with.  Check it out to help you with your solar boat packet reflection questions.

Thank you to the ones who emailed me with questions and concerns.  I appreciate you taking the initiative to ask and seek help.  All the best!

Many of the students explained to me that they saw the hot water (red water) move upward and the cold water (blue water) move to the bottom. One students explained that the blue water is going down because it is denser or heavier than the hot water, which is lighter. Another student compared it to being in the ocean. He explained that when hanging out in the water, he sometimes feel the cold water on the bottom and the warmer water at the top. Then another student realized that this experiment was like a thermometer. When the liquid in the thermometer gets hot it expands up and when cold it contracts and goes down.

What do you think?

Please watch the following video about how to set up your experiment for today’s class.
