This idea is part of a worldview which sees a oneness in all things. According to this, there is no true separation deeper than appearances. If something happens to one person, it affects many others to which that one is connected. In an ecosystem, if the primary consumers suffer, the secondary consumers suffer, and so on. The work we did in class on the topic of energy flowing through an ecosystem showed this.
Sustainability means positive actions now so that the world is better in the future. Simply put, it’s thinking ahead. If we cut back use of fossil fuels now, the world will be a more pleasant place to live 50 years from now than it would if we were to continue on our present course. Many of our projects done in this class have had at least one question on the topic of sustainability (e.g. “What is the impact on the environment?”).
I wanted an app that would help me memorize the periodic table.
I was hoping that it would be fast and simple, with the element name, atomic number, and atomic mass.
The app I chose is called K-12 periodic table. It has the options of showing classification, melting point, boiling point,outermost orbital, radius, ion radius, electronegativity, and ionization energy. There is also the option of the temperatures in the app being shown in Celsius, Fahrenheit, or Kelvin. This makes it user-friendly to both Canadian and US citizens.
I found that although the app has its uses, it often lags and is generally slow. It doesn’t have any particularly intuitive or creative features, and is more complicated than it needs to be. Many of the options in this app are unnecessary for the understanding level of a ninth grade student. So, for all the above reasons I wouldn’t recommend this app for learning about the periodic table.
