Unobserved Science Lesson
Grade Level: 1
Specific Lesson Objective: Students will know what plants need. Students can conduct simple
experiments/investigations related to plant needs by testing one variable at a time.
Materials: The Tiny Seed, sprouted lima bean, poster-size paper, marker, plastic sandwich
baggies with blank labels, bean seeds, paper towels, water.
B. Instructional Procedures
Engage: Read The Tiny Seed while kids are seated on the rug. Ask students what the seed
needed to sprout and grow into a big flower. Show students the sprouted lima bean. Ask: what
does the seed need for the baby plant inside to sprout? What do plants need from their
environment? *Go over the meaning of environment: Ooh, I just said a really big word,
“environment.” Let’s all say it: environment. Who can tell me what environment means? Make
sure they understand it means everything that is around us. (If children have difficulty with the
word “need,” remind them they talked about it the other week: Remember when you talked with
Mrs. Z about the difference between a want and a need? Who remembers what a need is?)
So, what do plants need from their environment to survive? Record answers on poster. Ask
students, “How would we find out? I wonder what we could do to find out what seeds or plants
need to grow.” Record answers on poster. This is called investigating! Say it with me,
“Investigating!” Now we get to investigate!
Explore: Demonstrate to children how they will be placing a bean inside a plastic bag with a wet
paper towel. Say: we know seeds and plants need water, air, food, and sunlight from their
environment, but we are only going to put water in the bags. There will be air in the bags and the
seeds will get some light from the windows because we are going to tape the bags to the
windows.
Excuse children back to their desks.
I am going to give each of you a seed. I don’t want you to touch the seed. What I want you to do
is draw a picture of what your seed looks like in box #1 on your worksheet (point to box #1 on
the graphic organizer).
Say: Everyone point to box #1 (the top box). In this box, draw a picture of what your seed looks
like.
Now I am going to give each of you a baggie with a water-soaked paper towel in it. First, I want
you to write your name on the name tag.
Say: Everyone point to the white tag; now write your name on it.
Now I want you to put the bean seed in the baggie and close the baggie tightly. What are we
going to do with the seed? (Make sure they understand directions.)
Demonstrate as you put a seed in a bag.
*Circulate room to help as needed.
Collect bags.
Say: Everyone point to box #2.
Now have them make a prediction on their worksheet: I want you to write a sentence and draw in
box #2 what you think will happen to your seed after being in the baggie for a week. Do you
think it will sprout? Do you think the baby plant inside will start to grow? Will it stay the same?
Put graphic organizer under the doc cam and demonstrate a think-aloud: I think my seed will …
(sprout, grow, stay the same). Mention that this is called a prediction; we are predicting what we
think will happen. Is it ok if our prediction is wrong? Yes!
*Circulate room and help as needed.
Explain: Now that we have started our investigation, think about what plants need from their
environment to grow and survive, then share with your neighbor. Have children use the sentence
frame, “Plants need from their environment …” (Have them repeat it after you.)
Ask: what do plants need? Record answers on the whiteboard: water, air, food, and sunlight. And
what can we do to find out what plants need?
Elaborate: Check student understanding by connecting to what other living organisms like
people need to survive. Ask: if plants need water, sunlight, air, and food to survive, what do you
think people and other animals need to survive? What do we need from our environment to
survive?
Evaluate: Exit Ticket (students may draw or write answers).
