Transcript of "Leaf Science Gr2"

  1. 1. Leaf Science! An Adventure & Exploration By Mr. Jarrett K-4 Computer Lab
  2. 2. Leaf Science! <ul><li>Leaves, leaves – most are still in the trees! (But not for long…) </li></ul><ul><li>Leaves give us SHADE in the summer. </li></ul><ul><li>But that’s not WHY they exist! </li></ul>
  3. 3. Leaf Science! <ul><li>Trees and plants need leaves to survive. </li></ul><ul><li>Trees and plants use leaves to make their own food. </li></ul><ul><li>When trees don’t need to make food any more, the leaves fall off. </li></ul>
  4. 4. Leaf Science! <ul><li>Leaves use water from the roots and carbon dioxide from the air into food for the tree using sunlight and something called chlorophyll . </li></ul><ul><li>This process is called Photosynthesis . </li></ul>
  5. 5. Leaf Science! <ul><li>Leaves are FOOD FACTORIES for trees and plants! </li></ul>
  6. 6. Leaf Science! <ul><li>Leaves get their GREEN from something called Chlorophyll . </li></ul><ul><li>When the Chlorophyll is all used up, the leaf changes color, usually to red, yellow or orange. </li></ul>
  7. 7. Leaf Science! <ul><li>Leaves come off the trees in the fall and need to be picked up. </li></ul><ul><li>Did you ever wonder why trees drop their leaves? </li></ul><ul><li>It’s because the trees are getting ready for winter – by closing their food factories! </li></ul>
  8. 8. Leaf Science! <ul><li>Winter days are short and dry. As the days have less sunlight, plants know to stop making food. </li></ul><ul><li>The chlorophyll goes away and leaves change into the colors that were in the leaves all along. </li></ul>
  9. 9. Leaf Science! <ul><li>Leaves have these main parts: </li></ul><ul><ul><li>Petiole (stem) </li></ul></ul><ul><ul><li>Veins </li></ul></ul><ul><ul><li>Blade </li></ul></ul><ul><li>Today we’re going to see leaves up CLOSE! </li></ul>
  10. 10. Leaf Science! <ul><li>You and your partner will have a turn using the microscope. </li></ul><ul><li>You will also get a turn using the computer. </li></ul><ul><li>You will get to explore a leaf and take snapshots. </li></ul><ul><li>What will YOU find?!? </li></ul>
  11. 11. Leaf Science! <ul><li>Do all the leaves look the same? </li></ul><ul><li>How are the leaves different? </li></ul><ul><li>Are there any features that all the leaves have in common? </li></ul><ul><li>How many 'points' do the leaves have? </li></ul><ul><li>Let’s find out! </li></ul>10x 60x 200x
