现在有很多的同学都很重视IB考试,有的则正在准备IB考试,这个考试是世界通用的一个预科文凭考试,它的含金量还是比较高的,并且IB考试的科目有很多,大家在选择科目的时候,还是要慎重选择的,其实IB环境系统就是其中的一种,它越来越受大家关注了,那么IB环境系统主要学习什么?IB环境系统考试技巧是怎样的呢?下面易伯华国际课程辅导就给朋友们详细的来阐述下这些内容。IB环境系统

IB环境系统学什么? 一起揭开这个冷门课程的神秘外衣

一、IB环境系统学学什么?

ESS相当于生物里面ecology的一个拓展,然后它除了单从生物学上来讲ecology(生态环境的关系,一些生态系统的循环过程),同时也讲它和社会的关系,跟人文社科有关(一些工厂,human impact on natural environment之类的)。其实ESS作为既是实验又是社科,科学的成分有,但是它主要是像ecology之类的。所以它所需要的设备并不需要很高的要求,它主要是涉及户外的一些活动。

如果同学们十年级没有学过生物或环境的话,也是可以选择这门课程的,就是你可能会比别人背稍微多一些的概念和定义。

二、IB环境系统学Presentation与Essay情况

会有presentation,但不会很多,不像商学。这些presentation都会计分,而我准备起来大概要花一到两个小时。理论上来说应该是要写很多essay的,但是我们并没有写过essay。

关于分数方面的,ESS的7分挺难拿的,但是6分就比较容易(大多数学生都是6分,只不过是low 6和high 6的区别)。

IB环境系统学考试技巧

首先,快速想一下这个问题会涉及到的topic以及题目想要让你答的知识点,具体回答的时候一定要囊括到题目想要问的知识点就好。(记得看所答题有几分,答题时至少要有和分值相符的知识点数量)。而平时就是做好上课的笔记,书上关键的地方读一读,记一些关键的词汇,答题思路还是靠平时积累。

如果你的理科能力不是很好,还是可以考虑选择IB环境科学作为自己的科学课的。同样如果你没有选择人文类课程,也可以选修IB环境科学。IB环境系统

IB环境系统相关介绍

System and Models

system – a collection of interrelated parts that work together by way of some driving process.

surroundings – everything around the system being studied

open system – exchanges energy and matter with surroundings. Most ecosystems are open.

closed system – exchanges energy but not matter with surroundings. Our planet is [usually] closed.

isolated system – exchanges neither energy nor matter with surroundings. Laboratory experiments are usually isolated.

- First Law of Thermodynamics: Conservation of energy.

Energy cannot be created or destroyed, only transformed from one form to another. There is a fixed amount of energy in the universe. Therefore living organisms must get their required energy from their environment and surroundings.

-Second Law of Thermodynamics: In an isolated system entropy tends to increase spontaneously.

When energy is converted from one form to another, some of the energy is degraded into less-usable heat which disperses into the environment. Thus the amount of energy remains the same, but its usability decreases.

Entropy measures the amount of disorder in the universe – usable energy is more organized whereas less-usable energy is more diffuse/disorganized. Entropy increases naturally, or spontaneously.

Equilibrium – A state of balance among the components of a system

Stable equilibrium - The condition of a system in which there is a tendency for it to return to a previous equilibrial condition following disturbance

Steady-state equilibrium – The condition of an open system in which there are no changes over the longer term, but in which there may be oscillations in the very short term. There are continuing inputs and outputs of matter and energy, but the system as a whole remains in a more-or-less constant state.

Dynamic equilibrium – there is no specific ‘average’ state; the system has different average states at different times. After a disturbance, the system may move to a different ‘average’ state.
