Created by future teacher Annabel Lee

2. Life
cycles of
plants
NJCCCS 5.3.2.B.1
and 5.3.2.B.3
and 5.3.4.D.1
Exhibit A:
Pine Cone

3. 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?

4. Exhibit B:
Avocado
tree and
avocado pit
This tree grew
from a small
round pit

5. Here’s the
avocado pit
close up…
Can you see the
root beginning
to grow?
How can we
help that root to
sprout?

6. 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?

7. 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

8. Trilobites
were extinct
before dinosaurs
even came into
existence!
Trilobites
NJCCCS 5.4.4.B.1

9. 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?

10. Measuring and weighing
using common household tools
NJCCCS 5.1.4.B.2 and 5.2.4.A.3

11. 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

12. 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

13. 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?

14. 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?

15. Sea Creatures
NJCCCS 5.3.2.C.2

16. Scallops and Coral
live in the sea
• Sea water is salty
• Many living organisms live
in the sea
• Some sea creatures live
inside shells
• Some sea creatures live at
the bottom of the ocean
and move and grow
without shells

17. Sponges and Barnacles
•Have you ever seen a
barnacle on the side
of a boat or on a
dock? Did you know
that it was alive?
•Did you know that
sponges are sea
creatures?

18. Clam, Oyster, Scallop
•Have you ever eaten one
of these sea creatures?
•We eat these fresh
shellfish raw or cooked
