Trees and Plants Around Us

Noticing plant parts, needs, and places where plants grow

Science - Grade K-1

Instructions: Read each problem carefully. Draw or write your answer in the space provided.
  1. 1

    Look at a tree. Name one part of the tree you can see.

    Think about the tall middle part or the green parts.

    One part of a tree you can see is the trunk, leaves, branches, roots, flowers, or fruit.
  2. 2

    Circle the things a plant needs to grow: water, sunlight, rocks, air.

    A plant needs water, sunlight, and air to grow. A plant does not need rocks to stay alive.
  3. 3

    Draw a plant with roots, a stem, and leaves.

    Roots usually grow down, and leaves grow up where they can get light.

    The drawing should show a plant with roots under the soil, a stem above the soil, and leaves on the stem.
  4. 4

    A seed is planted in soil and gets water and sunlight. What can happen to the seed?

    The seed can sprout and grow into a new plant.
  5. 5

    Which part of a tree helps hold it up and carries water to the branches?

    It is the big, strong middle part of a tree.

    The trunk helps hold up the tree and carries water to the branches.
  6. 6

    Name one place where plants can grow around your home or school.

    Plants can grow in places such as a yard, garden, park, sidewalk crack, pot, or school playground.
  7. 7

    Look at a leaf. Tell one thing you notice about it.

    You can notice its color, shape, size, or lines.

    A leaf may be green, flat, smooth, bumpy, round, pointy, or have lines called veins.
  8. 8

    True or false: All plants look exactly the same.

    False. Plants can look different because they can have different sizes, shapes, leaves, flowers, and colors.
  9. 9

    A plant has dry soil and droopy leaves. What should you do to help it?

    Dry soil is a clue.

    You should give the plant water because plants need water to stay healthy.
  10. 10

    Match each plant part to what it does: roots, leaves, flowers. Roots take in water. Leaves use sunlight. Flowers can help make seeds.

    Roots take in water, leaves use sunlight, and flowers can help make seeds.
  11. 11

    Which is usually bigger: a tree or a small flower plant?

    Think about which one may be tall enough to stand under.

    A tree is usually bigger than a small flower plant.
  12. 12

    Why should we be gentle with plants?

    We should be gentle with plants because plants are living things, and pulling or breaking them can hurt them.
  13. 13

    Draw or write about one plant you have seen outside.

    Think about a plant in a park, garden, yard, or near a sidewalk.

    The answer should show or name a real plant, such as grass, a tree, a flower, a bush, or a vegetable plant.
  14. 14

    Look at the picture of two plants. One plant is in sunlight, and one plant is in a dark box. Which plant is more likely to grow well?

    The plant in sunlight is more likely to grow well because plants need light to grow.
  15. 15

    Put these steps in order: small plant, seed, sprout.

    A plant starts very small before it grows leaves.

    The correct order is seed, sprout, small plant.
