Free 4th Grade Types Of Germination Lesson Plan (Science)

Topic: Types of Germination

Objectives & Outcomes

• Students will be able to explain the different types of germination and describe the characteristics of each type.

Materials

• Small containers (such as egg cartons or cups)
• Soil
• Seeds
• Water
• Desk lamp or sun lamp (optional)
• Handouts with photos of different types of germination

Warm-up

• Ask students if they have ever seen plants grow. Ask them to describe what they saw.
• Review the different stages of plant growth (seed, root, stem, leaf, flower, fruit). Ask students to name each stage.
• Ask students if they know what happens before a plant grows into a seed.

Direct Instruction

• Explain that before a plant grows into a seed, it needs to germinate, or sprout. Germination is the process by which a seed begins to grow and develop into a plant.
• Show students different types of seeds (e.g. beans, peas, corn). Ask them to identify each seed type.
• Explain that different types of seeds germinate in different ways. Some seeds need to be soaked in water before they will sprout, while others need to be placed in the soil. Some seeds will sprout only if they are exposed to certain temperatures.
• Explain that there are four main types of germination:
• Hypogeous germination: Occurs when a seed sprouts underground, without any visible sprout or stem above the ground.
• Epigeal germination: Occurs when a seed sprouts above ground, but the sprout remains under the seed coat.
• Emphyllous germination: Occurs when a seed sprouts above ground, with the sprout and stem emerging from the seed coat.
• Euterpean germination: Occurs when a seed sprouts with the sprout and stem emerging from the seed coat, and the seed coat remains on the sprout.
• Have students take notes on the different types of germination.

Direct Instruction:

• Divide students into small groups and give each group a set of seeds.
• Have each group make a chart showing the type of germination each seed undergoes. Have them write a sentence explaining why each seed germinates in the way it does.
• Have each group present their charts and sentences to the class.
• As a class, discuss why different seeds germinate in different ways. Ask students if they can think of any reasons why a seed might germinate in a certain way.

Guided Practice:

• Have students work in pairs to find a seed and a medium to germinate it. They should carefully monitor the germination process and take notes on any differences between the seed they have and the seeds in the previous activity.
• Have students present their findings to the class and explain why the seed germinated in the way it did.

Closure:

• Review the different types of germination that were learned in the lesson.
• Ask students to share something they learned about germination, or something that surprised them.

Assessment:

• Observe students during the simulation activity to assess their understanding of the different types of germination.
• Collect and assess the classification worksheets to ensure students can accurately and confidently identify the type of germination of different seeds.
• Have students complete a short reflection on the lesson, including what they learned and what they found most interesting or surprising about germination.
