Agreement on Plants!

5/19/2020

 
After a thoughtful discussion on what we know about air, water and light, we came to an agreement that:

1. Air is made of matter because it has weight.  If it has weight, it must be made of particles, too! And since air was compressible in a syringe (Mrs. Brinza did a demo w/one of her kid's syringes used to administer medicine), there has to be a lot of empty space around the particles!

2.  Water is also made of particles, too!  Duh--water obviously has weight, no?!?!?!  We also tried it in the syringe and while it's compressible, it was BARELY compressible, which means the particles in water must be really close together.

3. Light doesn't have weight and can't be made of particles, NO WAY!  Since it travels in straight lines and comes from a source, we agreed that an arrow would be the best way to represent it!
Picture
Mrs. Brinza built out an animation to see how air, water, and sunlight are used to help a plant grow!
We continued to see another pattern emerge...if an organism gets bigger, then something else (in this case, the air and water) had to be getting smaller!  All this couldn't take place without energy present, too!  Check out our mathematical model we built!
Picture
Next steps:  return back to the dead raccoon that started this all!

    Have you ever seen something like the dead raccoon above?  Did it disappear?
