Kindergarten Lesson: Plants, Insects, & Humans

Common Core:

Next Generation Science Standards

K-LS1 From Molecules to Organisms: Structures and Processes

LS1.C: Organization for Matter and Energy Flow in Organisms. All animals need food in order to live and grow. They obtain their food from plants or from other animals. Plants need water and light to live and grow. (K-LS1-1)


The purpose of this activity is to create a skit where the children can see the cycle of food consumption. Also, to see how plants, animals, and humans rely on the sun for energy and life.

Key words (Make a Vocab Tree):

Sun, Energy, Nutrients, Photosynthesis


  • Food Chain Diagram
  • Pen
  • Index Cards (labeled 1,2,3,4) for all students.

1 = Sun (Only 1 card with #1)

2 = Plants (3 – 4 cards with #2)

3 = Insects & Animals (5- 7 cards with #3)

4 = Humans (remaining number of students)


Introduce to the students that they will be creating a skit about the food cycle. Give an example of the food cycle, to interest students.

Talk with class about the importance of food, and how the food cycle works. Talk about how we all need energy to live, and energy comes from food. Plants need sun for energy, insects and animals eat plants, humans eat plants and sometimes animals, and the sun provides energy to plants. The sun also provides insects, animals and humans with energy by providing them with food.

The next step is to assign the students their roles.

Randomly distribute index cards to each student. Ask which student has the card with a 1 (the Sun). Have that student stand in the middle of the room. Next have the students with a 2 card stand in a circle around the Sun. These are the Plants that need the Sun’s energy to grow through photosynthesis. Ask the students with a 3 card to stand in a circle around the Plants. These are the Insects & Animals that eat the Plants that need the Sun’s energy to grow. Finally, ask the students with a 4 card to stand in a circle around the Insects & Animals. These are the Humans that eat the Insects & Animals that eat the Plants that need the Sun’s energy to grow.

From here, you can ask different elements of the food chain to disappear (by either leaving the circle or laying down), and explain that sometimes this happens when the climate changes and plants, insects & animals can’t adapt quickly enough.

You could also have the Insects & Animals “eat” the Plants (so the Plants disappear), then have the Humans “eat” the Insects & Animals (so the Insects & Animals disappear). Ask your students what happens when we eat everything, and there are no insects & animals or plants left?

Ask students if they have a favorite plant, and how they would feel if that plant disappeared. What about a favorite animal?
