Acids and Bases 5/14/17

Summary:
The pH scale tests how acidic or basic a substance is. Acids have a pH ranging from 0 to 6.9. The lower the pH, the stronger the acid. An acid that has a pH of 6 is weak while an acid that has a pH of 1 is strong. Bases have a pH ranging from 7.1 to 14. The lower the pH, the weaker the base. A base that has a pH of 8 is weak while one that has a pH of 13 is strong. Neutral substances have a pH of 7. One example of a neutral substance is water. Acids have a sour taste, while bases have a slippery feel. Acids turn a litmus paper red and bases turn litmus paper blue. A litmus paper tests a pH of a substance. Fun fact, even though it is better to drink an acid rather than a base cough syrup is a base (it stabilizes the acids in your stomach).
S&EP:
Even though we didn't do anything big this week, like an experiment, my group and I carried out a mini investigation of our own. As we have been doing lately, we play the legends of learning games, but we focused in on the topic of the environment to prepare us for the science portion of the end of the year project. We did cover this topic last year, but there were some things we just forgot. When a question popped up that we didn't know we worked together using the process of elimination to figure out which answer is correct. Using this process throughout the week my team and I learned a lot. For instance, I can clearly remember that the geosphere is dirt and soil while the hydrosphere is all the bodies of water like lakes and rivers. As for the biosphere, it is all livings things and the stratosphere is the gasses or the air. Without this mini-investigation or legends of learning, I don't think I would have been this productive this week.
XCC-Cause & Effect:
This week there was a very obvious cause and effect relationship I noticed while learning about the Environmental Accords. The Environmental Accords are 21 different policies, that would make the city or the community you live in sustainable, clean, and a better place to live. The Accords are divided into energy, waste reduction, urban design, urban nature, transportation, environmental health, and water each hoping to better the environment. I know you are probably still wondering where the cause and effect relationship comes in? Well, Each specific policy has a direct result. For example, implementing wastewater management guidelines as well as reduce the volume of wastewater discharges by 10% in 7 years will result in preserving clean water for more people to use. Another policy states that creating a rule that prevents waste from entering landfills by 2040 will lead to less methane gas produced slowing down the heating of the earth. This cause and effect showed me that adding these policies into your community will make it very eco-friendly.
Multiplier:
This week I was a mutant, to be more specific a learner because I tried to soak up as much information as possible on this new topic (Environmental Accords).
