Lesson 1 : Plant needs
Activity 1: Can you explain?
How do the structures of a plant use water ,
air and light to perform life processes?
- Plants have roots , stem , leaves and
Sometimes flowers or fruit.
- Each part of a plant has its own function ,
Where the roots help the plant and nutrients
from the soil and other parts of plant help it survive.
Activity 2: tree needs
- Plants use structures that are unique
among living organisms to produce
Their own food using sunlight.
- When a tree is planted , it begins to grow
From a seedling into a mature tree depending
On some resources such as water , air and sunlight
to make their food to survive.
Circle the items that plant needs to grow :
Activity 5: what do you already know about plant needs?
- Water and air are basic needs of plants,human and animals.
- Humans and other animals need to eat
food to gain energy and nutrients to live and grow.
- Most plants get nutrients from
soil and make their own food through
a process known as
“ photosynthesis process” that
takes place in the plant leaves.
- Soil may not have been included as
a basic plant need because:
Some plants only
grow in water
Some plants grow on
other plants instead
of having roots in the
Soil.
Plants and food :
Plants make their own food which is
a type of sugar that provides the plants
with energy to grow.
- Plant make their own food in their leaves
by means of photosynthesis process ,
where the roots of plant absorb water and nutrients from
the soil.
- Water and nutrients are carried from the
roots to the leaves through the stem.
Activity 6: Do plants need soil?
- We will germinate some seeds in a wet paper towel ,
measure their growth and then compare their growth to
the growth of the other seeds which are placed in soil :
Tools :
plastic cup
contains
potting soil
Paper towel six bean seeds (fava beans)
Metric ruler
water
Plastic plate
Steps :
1- use the water to wet the paper towel.
6- Measure the growth of each seed using the metric ruler.
2- place 3 seeds in the top half of the paper towel and
Fold the bottom half of the towel up so that it
covers the seeds then ,place the paper towel
inside the plastic plate.
5- Check the growth of seeds over the next several days .
Wet the paper towel and water the soil as needed .
3- plant the other three seeds in the cup that
Contains potting soil then , water the seeds.
4- place the plate and the cup in a place where
they can get sunlight .
Observation :
The initial growth of the seeds
placed in the
paper towel is similar to that of the
seeds planted in the
Soil.
Conclusion :
- The seeds can grow without soil if
they have water and sun.
- Plants can grow without soil for a
while , but finally they need soil.
Photosynthesis
Photosynthesis process: is
the process through which
plants use the energy in
sunlight to make their own
food.
Activity 7 : Sunlight :
a basic need
Photosynthesis is important
because it provides two main
things:
Food Oxygen
- Green plants use their leaves to collect sunlight
and carbon dioxide from the air .
- Inside the green plant, sun light allows carbon
dioxide to combine with water to make sugar ,
which gives the plant the energy it needs to grow.
Oxygen that is produced during photosynthesis is
released into the atmosphere. This oxygen is what
we breathe and we cannot live without it
We will do an experiment to show the
effect of light on plant growth:
Tools :
Two plastic
cups
Potting soil
Two bean
seeds
Water
Steps :
1- Add soil to the two cups , place the bean seeds
on the soil , one per cup and cover the seeds with
about 2 centimeters of soil.
2- Add the same amount of water to each cup to
moisten the soil.
3- Place the red cup where it will receive light and
place the other cup in the dark.
4- Water both plants regularly and observe them
along two weeks.
- Observation:
After two weeks , we observe that :
- The plant in the first cup grew
taller than the plant in the other
cup.
- The plant in the first cup has four
leaves with dark green color ,
while the plant in the other cup
has two small leaves with pale
green color .
- Conclusion :
- Light is a basic need for the plants ,
like water , air and nutrients .
- Light is important to plant growth
because plants use light to make
their own food so the plant
without light does not grow well
because it had less food.
Activity 8 : plant structure
- Plants roots absorb water and nutrients from
the soil and carry them to the rest of the
plant.
- Water and nutrients move up the plant’s
tubes or vessels called xylem.
- Leaves collect sunlight.
- Also , the air that plant need moves into
the leaves through tine openings called
stomata .
Stomata : they are pores on the
surface of plant’s leaves that allow
gases to move into and out of the
plant .

  • 1. Lesson 1 : Plant needs Activity 1: Can you explain? How do the structures of a plant use water , air and light to perform life processes? - Plants have roots , stem , leaves and Sometimes flowers or fruit. - Each part of a plant has its own function , Where the roots help the plant and nutrients from the soil and other parts of plant help it survive.
  • 2. Activity 2: tree needs - Plants use structures that are unique among living organisms to produce Their own food using sunlight. - When a tree is planted , it begins to grow From a seedling into a mature tree depending On some resources such as water , air and sunlight to make their food to survive.

  • 4. Activity 5: what do you already know about plant needs? - Water and air are basic needs of plants,human and animals. - Humans and other animals need to eat food to gain energy and nutrients to live and grow. - Most plants get nutrients from soil and make their own food through a process known as “ photosynthesis process” that takes place in the plant leaves.
  • 5. - Soil may not have been included as a basic plant need because: Some plants only grow in water Some plants grow on other plants instead of having roots in the Soil.
