Lesson 1: Plant Life Cycle
Lesson 1: Plant Life Cycle
Plants are living things that belong to a special group called Plantae. Most plants make their food using sunlight. They do this with tiny parts inside their cells called chloroplasts. Chloroplasts use a green substance called chlorophyll to capture sunlight and turn carbon dioxide and water into sugars, which give the plant energy to grow.

The Life Cycle of a Sunflower
The Life Cycle of a Sunflower
Step 1 - Seeds
Sunflower seeds have black and white stripes. When the seeds are planted in the ground or they fall from the seed head and settle, they can begin to grow.
Step 2 - Germination
About three days after planting the seeds will germinate. This means that the hard shell softens and splits. Roots begin to grow downwards and shoots begin to grow upwards.
Step 3 - Seedling
After about a week the shoot will appear above the soil. Then leaves will start to grow. As time passes the leaves and stems will get taller, broader and thicker.
Step 4 - Young Plant
As the seedling grows buds will form. These will begin to unfold into petals.
Step 5 - Adult Plant
: The sunflower reaches adulthood, and the flower blooms.
Step 6 - Seeds Fall
The plant wilts and dies. The seed head dries out and releases the seeds for the cycle to begin again.

Self Watering Milk Jug Planter
Self Watering Milk Jug Planter
What You Need:
An empty milk jug
Scissors
Milk lid
Drill, bit & wood
Seedling
Soil
Permanent markers to decorate
Step 1: Take the label off the milk jug. If it’s hard to peel off, fill the jug with warm water and wait a couple of minutes. Then try again.
Step 2: Cut the jug in half, just under the handle. You should use the 'big scissors' from the wall. Remember to trim the edges so they aren’t sharp.
Step 3: Decorate the bottom part of the jug any way you like! You should write your name and plant type on it, plus today's date.

Date
Step 4: Turn the top half of the jug upside down. Drill holes in the lid and place it inside the bottom half.
Step 5: Fill the top half with 1 cup of soil and plant your seedling. Pour some water into the bottom half of the jug. The plant will drink the water when it needs it!
Plants are living things that belong to a special group called Plantae. Plantae is the Latin or scientific name for plants. See if you can read the following scientific names and guess what they stand for, such as Plantae and plant.

Lesson 2: Green House
Lesson 2: Green House
A greenhouse is a structure, typically made of glass or transparent plastic, used to grow plants by creating a controlled environment that is warmer than the outside temperature. It utilises the greenhouse effect to trap heat from solar radiation, allowing plants to thrive even in cooler climates or seasons.
Transparent Covering:
The key feature of a greenhouse is its transparent walls and roof, usually made of glass or plastic. This allows sunlight to enter and heat the interior.Heat Trapping:
The sunlight that enters the greenhouse warms the air, plants, and other materials inside. This warmed air is then trapped by the transparent covering, creating a warmer environment than the outside.Controlled Environment:
Greenhouses allow for the regulation of temperature, humidity, and light, providing optimal conditions for plant growth.Plant Cultivation:
Greenhouses are used to extend growing seasons and cultivate plants that require specific temperature and humidity levels.Plant Protection:
The greenhouse will protect plants from harsh weather conditions. Animals, wind and storms can cause plants to die.
My house is made to trap sunlight.
My greenhouse has a watering bottle and a door that opens.
My pea plant is growing tall!
I made a house to keep my plants safe.
Task:
Task:
Make your 'self watering milk jug planter' into a greenhouse.
A: Transparent Covering, you should be able to open and close the house.
B: Heat Trapping, you must be able to trap heat by making it close tightly.
C: Plant Cultivation, you must be able to water the plant and have room for it to grow.
D: Plant Protection, you must be able to keep the plant safe from wind and predators.
Remember: You are building a prototype! Next week, we will adapt or change your greenhouse as needed.

If fertiliser is used on a plant
then the plant
will grow taller than the non-fertilised plant.
