Science Unit Lesson Plan
Mary Blair Elementary
Inside a Seed
Literacy Focus: Vocabulary
Literacy Instruction: Buddie Reading, Individual Reading
Colorado Standards: Standard 1, 4, 5
Lesson Objective: Students will observe lima beans that have
been soaked in water overnight and identify the major parts of
the seed. This will help them understand how a plant begins.
- Hook and activating background knowledge: remind them
that one of the questions from our KWL was “what happens
to seeds as they grow?” With a reading buddie, read the
book Growing Radishes and Carrots which show diagrams and
time charts of how specific seeds grow.
- Pre-Assessment: Ask them to think about “what happens
when a plant grows?” for a minute and then discuss it with
their partner. Listen to their discussion to gain information
about what they believe about seeds.
- Explantion of what will be learned: Tell them that all seed
coats consist of two part, the little plant(or embryo) and
the seed coat. The seed coat protects the developing plant;
the embryo is inside the seed. Cotyledons store food. They
are the leaves that are attached to the little plant or
embryo. When the seed begins to grow, one part of the
embryo becomes the root and the rest becomes the upper
stem and leaves.
- Explain and Model: Give each student one water soaked
seed and one dry lima bean. Observe and write down the
color, texture, firmess, etc. Share their information with
their buddie. Remind them to use good descriptive words.
Trace the seed on the ruler and measure its length. How is
the wet seed different from the dry seed?
- Written directions and guided practice: Look at the seed
coat and find the spot where the seed was attached to the
pod. This small hole in the seed coat lets water into the
seed. Carefully remove the seed coat and place it to one
side. Identify on the worksheet. Carefully split the seed
into two parts. Look at the two halves. Identify the
embryo. Find the food storage area of the plant.
- Formative Assessment: ask questions such as “What did the
dry seed look like?” “Could you find the spot where the seed
was attached to the pod?” Describe the inside of the seed.
-Instruct students to complete the seed to plant process by
drawing it in their Science Journal.
-Post Assessment: Look over their labeling sheet and their
Journal to make sure they understand the parts of the seed and
the growing process.

Closure: This lesson should help you to answer a few of the
questions you had about plants and to better understand how a
