The twins Mike and Mary are fascinated by jungles after learning about them. They ask their mother if they can make a plant jungle at home. Their mother thinks it may be possible. The document then provides instructions on how to create a plant jungle by putting soil and compost in a plastic jar, planting lettuce and bean seeds, watering them, and observing their growth over weekly periods. Key factors for plant growth like water, light, soil, temperature, and nutrients are also explained.

12. Creating a plant jungle
The twins, Mike and Mary, have been
reading books and watching television
programs about jungles. They are
fascinated by all the plants and trees
that grow there and how different it is
from their garden. ‘I wish we lived in
the jungle,’ Mary said to her mum.

13. Well,’ mum said ‘I don’t think we can
do that but we can try to make one’.
That’s impossible,’ said Mike.
What do you think-is it possible?

14. The factor for plants growth
Water: Water is essential because it moistures the soil
and dissolves important nutrients that the plant needs
in order to grow.
Light: Light is a factor required in order that
photosynthesis can occur in plants.
Soil: The soil serves the needs of the plant by providing
water, air, nutrients, and stability.
Temperature: Plants grow well only within a limited
temperature range. Temperatures that are too high or
too low will result in abnormal development and
reduced production.

15. Oxygen: Plants require oxygen for respiration to carry out
their functions of water and nutrient uptake.
Carbon Dioxide: Carbon Dioxide (CO2) contributes to
plant growth as part of the miracle of nature known as
photosynthesis. This enables plants to combine Carbon
Dioxide and water with the aid of light energy to form
sugar.
Mineral Nutrients: Green plants must absorb certain
minerals through their roots to survive.
Humidity: The relative humidity present in the air is
utilized by the plants and this is a crucial factor for the
transpiration process of the plants.

be tested.
To be able to make and record
observations.
To know how to use drawings to present
results.

19. How to create a plant jungles
1.Put the soil and the peat-free compost in
the sweet jar, and mix them together.
2.Drop some seeds of the little gem
lettuces and the runner bean seeds in
the sweet jar.
3.Water the seeds by using the plastic
spray for water.

20. 4.Place each sweet jar on a flat surface
where it is warm and light.
5.Each week ,you will need to observe the
jungles closely and complete your
photocopiable pages.

21. Look at your sweet jar jungle each
week. Draw and write what you see.
