SEED GERMINATION
The goal of this lesson is to explore the process of seed germination and understand the scientific principles behind plant growth.

Lesson 1
Step-by-Step Instructions:
Step 1: Gather materials – plastic bag, paper towel, seeds, water dropper, tape, marker.
Step 2: Fold the paper towel to fit inside the plastic bag.
Step 3: Dampen the paper towel—moist, but not soaking.
Step 4: Place the seeds on the towel and seal the bag.
Step 5: Label with your name and seed type.
Step 6: Tape the bag to a sunny window.
Step 7: Check every few days—remove rotting seeds, keep the paper towel moist.
Step 8: Once the seedlings reach the top, carefully pot them!

How Seeds Grow & Why It Matters
Seed Anatomy
Seed Coat: Protects the seed.
Embryo: Baby plant inside.
Cotyledon: Stores food for early growth.
Germination Process
1. Water Absorption: Seed swells, coat breaks.
2. Energy Activation: Stored food is converted into energy.
3. Root Emergence: Roots grow down for water.
4. Shoot Growth: Stem and leaves push upward.
5. Seedling Stage: Leaves form, photosynthesis begins.
Photosynthesis: How Plants Make Food
Ingredients Needed:
Sunlight: Provides energy.
Water: Absorbed by roots.
Carbon Dioxide (CO₂): Taken from the air.
The Process:
Plants use sunlight to mix CO₂ and water, creating:
Glucose (sugar): Food for the plant.
Oxygen (O₂): Released into the air.
Why It’s Important:
Produces oxygen for us to breathe.
Powers the food chain.
Helps plants grow into the fruits, vegetables, and trees we rely on!
Respiration: How Plants Use Energy
Opposite of Photosynthesis: Instead of making food, respiration breaks food down for energy.
Process:
Oxygen + Sugar → Energy for growth.
Produces CO₂ and water as waste.
Why It Matters:
Keeps plants growing, repairing, and surviving—even at night
Provides energy for fruit, flowers, and new seeds.
How Plants Drink Water
Osmosis: Water moves from high to low concentration through plant roots.
Why It’s Important:
Brings in nutrients
Keeps plant cells firm
Prevents wilting
