Life Science · 40 minutes
Grade 1
5E lesson flow
01
Engage
6 min
Teacher Does
Show a dry seed beside a germinating seed without naming the stages.
Students Do
Notice visible differences and ask questions.
Ask
- What changed?
- Which details can you see without guessing?
Look For
Split seed coat, visible root, size or color changes.
02
Explore
12 min
Teacher Does
Set up matched damp and dry seed samples.
Students Do
Label setups, make a prediction, and record starting observations.
Ask
- What will change?
- What should stay the same?
Look For
Water condition changes; seed type, place, and observation schedule stay the same.
03
Explain
8 min
Teacher Does
Use a stage visual to identify seed, root, shoot, and seedling.
Students Do
Sequence the stages and connect names to visible structures.
Ask
- Which part appeared first in our sample?
Look For
Root before shoot in the observed bean sample.
04
Elaborate
8 min
Teacher Does
Present a new seed observation record with slightly different timing.
Students Do
Decide what claim is supported and what remains uncertain.
Ask
- Can one seed tell us exactly when every seed will germinate?
Look For
Recognition that timing varies.
05
Evaluate
6 min
Teacher Does
Collect the evidence check.
Students Do
Write one observation and one evidence-based claim.
Ask
- What evidence supports your claim?
Look For
Claim about the tested conditions, not an overgeneralization.
Student goal
I can use seed observations to explain what helps germination begin.
Learning objectives
- I can put germination observations in order from seed to seedling.
- I can compare a damp and dry setup and use evidence to explain why one seed begins to germinate.
- I can name the first visible root and shoot without claiming every seed sprouts at exactly the same time.
Materials
- Bean seeds
- Clear zip bags or cups
- Paper towels
- Water droppers
- Labels
- Hand lenses
- Rulers or centimeter strips
Before class
- Start one damp bean-seed sample 2–4 days before class so students can see an emerging root.
- Prepare a dry comparison sample using the same seed type.
- Keep an unstarted dry seed for the beginning-stage comparison.
- Do not seal wet seeds for long-term storage after the lesson.
Prior knowledge
- Plants are living things.
- Living things change as they grow.
- Scientists can compare two setups and record observations.
Vocabulary
- seed
- A young plant in a protective covering with stored food.
- germinate
- To begin growing from a seed.
- root
- A plant part that grows into the soil or growing material and takes in water.
- shoot
- The young stem and leaves that grow upward from a germinating seed.
- seedling
- A very young plant that has begun growing from a seed.
Differentiation
- Use real seeds plus enlarged visual stages.
- Offer the frame: I observed ___. This is evidence that ___.
- Allow students to point and orally describe before writing.
- For extension, compare two seed types without requiring them to germinate at the same speed.
Assessment
- Check sequencing of visible stages.
- Check fair-test reasoning.
- Check that observations are separated from predictions.
- Check that the final claim refers to this test.
Exit ticket
A seed on a damp towel grows a root. A matching seed on a dry towel does not. What is one claim the evidence supports?
Extension
Observe the same damp seed over several days and make a dated picture record of root and shoot changes.
