Report
Introduction
The term, 'biome' developed by scientists, is used to describe areas of the Earth and characterised by flora and fauna, which is maintained according to the climate of the region. The types of biomes explored include tropical forest, tundra, desert, grasslands, temperate forests, polar lands, boreal forest and mountain vegetation. In this experiment, everyone is assigned a biome to maintain and hopefully gain new findings, goals and achieve their experiment. During this experiment, the biome, desert is the main focus. Deserts, cover one fifth of the Earth’s surface and are extremely hot and dry yet some deserts can be cold at night. Through this study,
Hypothesis
Based on the knowledge gained about deserts during research, the desert will most likely not make any major changes. Over the weeks of maintaining the biome, it is predictable that cracks on the sand will form.
Materials and Methods
Materials
• Sand
• Another type of sand
• Rosemary
• Pebbles
• Rocks
• Lawn seeds
• Plastic container
Method:
1. Researched the layers of a desert.
2. Filled 1/4 of the container with normal sand and made a hill.
3. Filled another layer with bricky sand (regular orange sand)
4. Picked out rosemaries which represents a spinifex tree and placed it on the sand.
5. Placed rocks and pebbles on the sand.
6. Scattered lawn seeds.
7. Sprinkled drops of water.
Discussion
Some changes the biome showed include cracks on the sand, the grass growing and the rosemary dying. Over the weeks of maintaining my biome, the cracks on sand grew more bigger. The biome was only watered once and the lid was kept closed yet the grass still managed to grow. During the last week of keeping record of the biome, the rosemary began dying.
Conclusion
Over the weeks of keeping the biome in a good condition, it is evident that it has made significant changes such as cracks on the sand, the grass growing and the rosemary (which represents cacti) dying. Through this project, the biome, desert maintained in order to achieve our experiment, to attain what a biome is like.
