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.

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?

The factor for plants growthWater: 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.

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.

How to create a plant jungles1.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.

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.

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