    • Third to Fourth GradeScience Project
      Life cycle of plants
      Using measuring devices
      Created by future teacher Annabel Lee
    • Life cycles of plants
      Exhibit A:
      Pine Cone
      NJCCCS 5.3.2.B.1
      and 5.3.2.B.3
      and 5.3.4.D.1
    • Pine Cones
      This pine cone contains the seeds to grow pine trees
      This pine cone is 8 inches tall
      How tall do you think the pine tree will grow that comes from this pine cone?
      Look at the beautiful pattern!
      What other patterns in nature have you seen?
    • Exhibit B: Avocado tree and avocado pit
      This tree grew from a small round pit
    • Here’s the avocado pit close up…Can you see the root beginning to grow?How can we help that root to sprout?
    • Sprouting and growing seeds
      First put the seed into water – use toothpicks to hold the top of the seed out of the water and let the tiny root use the water for nutrients. Why is half the seed out of the water?
      When the root is sprouting put the seed into soil where the root can spread and gather nutrients
      Don’t forget to water that seed in the soil because the plant needs both soil and water to grow
      Watch the plant grow up toward the light. How long do you think it will take before leaves form on the stem?
    • Leaves, stems, roots, fruit
      The stem will grow up toward the sunlight
      The leaves will take in nutrients from the sun
      The roots receive nutrients from the water and the soil
      If you take care of your plant it will bear fruit
    • Trilobites
      Trilobiteswere extinct before dinosaurs even came into existence!
      NJCCCS 5.4.4.B.1
    • Trilobites lived under the ocean
      Scientists believe that trilobites had hard shells and many legs so they could walk on the bottom of prehistoric oceans and gather their food
      Scientists have identified gills on trilobites which means they lived underwater
      This trilobite was found on dry land far away from the ocean. What was it like in prehistoric times in the place where this trilobite was found?
    • Measuring and weighingusing common household tools
      NJCCCS 5.1.4.B.2 and 5.2.4.A.3
    • Measuring cups
      Using a 1/3 cup measuring cup, measure 1/3 cup of lentils. The lentils must fill the cup.
      Now pour those same lentils into a ½ cup measuring cup
      How much space do they now take up?
      Use fractions to discover how much of the ½ cup measuring cup they are filling
    • Using measuring cups for dry ingredients
      Now pour those same lentils into a full cup measuring cup
      Does it still look like the same amount of lentils?
      Does it look lie more or less than it did in the 1/3 cup measuring cup. Fill the 1/3 cup measuring cup with more lentils now and compare
    • Liquid measuring cups
      Now pour 1/3 cup of lentils into a one cup liquid measuring cup. How does it look? Does it fill much of the space in the cup?
      Now take a two cup liquid measuring cup? How does it look? Does it look like fewer lentils? A lot fewer? Why?
    • Measuring spoons
      On your own try measuring the lentils with the measuring spoons. How many tablespoons fill a cup?
      Weigh the lentils in each container and in each spoon. Do they weight the same? Why or why not?
