- In term 2 the 5/6’s at M.P.P.S did a unit on the deadly deserts. During this unit we had to do a project on a plant or animal that lives in the Australian desert, we did not choose our animal however we did a lucky dip. My partner and I focused on the Australian mulga (acacia aneura). In our project we had to complete a certain criteria. We had to put in the main adaptations from three areas: Behavioural, Structural and Physiological. We also had to add in how the animal would survive in their environment but without their adaptations. A piece of extra piece of information that we added was the life cycle, this showed how they have evolved, what happens in their life, their life expectancy and also how tall they get . I worked with Tirth for the project and I think we work well together and finished our project earlier than needed but to quite a high standard.
3 facts I found interesting
- I found out that the spencers burrowing frog was large eyes that helps it swallow it’s food and also that it has 2 back legs that help it burrow deep into the ground so that it can wait until there is water or moisture to help it survive and when there is it comes up to the surface.
- I found that the Thorny devil camouflages when it is cold, warm or even alert. The thorny devil also grows a lot during the period of time from birth to death. These creatures have an animal that looks a lot like it but has some different adaptations.
- I found out the Australian mulga has long and deep roots to help it get nutrients from deep in the soil to cool itself down because further down in the soil it gets cooler and cooler because it is not exposed to the hot or warm air that is above surface. I also found out that it grows to at least 7 metres in 70 years which means it grows 1 metre every 10 years and it grows to a maximum of 10 metres over 100 years which is about half their life span.
2 understandings that I gained
- I know understand how evolution helps animals to fit in to their environment and that evolution takes a long time, an example of an adaptation that has evolved over time for the Australian mulga is it’s long and deep roots which help it cool down, it also has phyllodes which are thickened leaf stems that are not leaves as such but do the job of them
- I now know that not all deserts are hot and not all deserts are sandy. I learned that Antarctica is a desert because it does not get much rain fall which is a factor of a desert. I now know that the Sturt’s desert in central Australia is rocky. I thought before this topic all deserts were hot all the time but most deserts are extremely cold at night.
1 question I still have
- How do the eyes of a spencers burrowing frog help it to swallow it’s food and how things change on an animal over time?
What where the most important things I learned
- I think the most important things I learned where the importance of team work and how it can help you finish what you need to do.
How did I learn it
- Some days when I was working with my partner we were not working well together and other days we were and then we got more of our work done. I think something that could help next time is not having one person take over the entire project and you have to evenly split the work load. I also think having more patience is key to a good presentation.
