Demonstrate Understanding of Chemical Reactions

Goal: Be able to use the law of conservation of mass to write balanced chemical equations, identify the basic types of chemical reactions, and predict the possible products from a given set of reactants.

You must demonstrate your achievement of this goal.  In a blog post, (1) explain how to balance an equation and why it is important, and (2) describe different labs you did, what type of reaction it was, and provide a balanced reaction for each.  You have done synthesis, decomposition, single-replacement, and double-displacement labs.

You must also (3) describe how to predict the possible products that will occur from a given set of reactants, and (4) demonstrate your ability to predict reaction products.

As of the first week of March, chemistry students have conducted the below list of chemistry labs. Use this list to support your evidence of attainment of the above goal.

1. Baking Soda to Salt Lab
2. Limiting Reactants Lab
3. Chemical Reactions Webquest
4. Three Types of Chemical Reactions
5. Reactivity of Metals
6. Hydrate Lab
7. Molecules of Candle Burned
8. Molecules of Chalk In Your Name
9. Covalent or Ionic Bonding Lab
10. Halides Lab
11. Periodic Trends
12. Ionic vs Covalent
13. Half life of Candium
14. Isotopes of Vegium Lab
15. Rutherford Lab
16. Law of Conservation of Mass
17. The quality of Laboratory Measurements
18. Measuring Stuff: Tools and Skills
19. Density Problems
20. Lab Skills Lab
21. Observations Lab

My Environmental Ethic

Assignment To Students:

Todays question is “What do you do to contribute to a sustainable environment?” Write a 300-word blog post on your environmental ethics.  Previously you have written in your journal about “what is an environmentalist”; you have also learned some new terms such as “sustainability”, “environmental footprint”, and “tragedy of the commons“. Finally, you have your own personal reason for being in this class. Combine all of these things with your class learning and tell us what are your environmental ethics. You might also think about things you want to do in the future that you have not done before; for ideas on these, go to What Can You Do?

My 300 (or more) Words:

I am deeply connected to our planet Earth and I think I always have been. My parents raised me to respect the planet, take care of her, and to know the names of her New England inhabitants. My mother would take my little sister and me on walks in the woods and name the trees and flowers and wild herbs. My father used organic gardening methods for our food (and all of our vegetables came from our garden) and was disgusted by builders who clear-cut a lot to put in a house; he knew they could have left some of the trees and still built the home, he felt the builder was just being lazy. This background is the structural foundation for the environmentalist in me.

When it comes to environmental ethics, every individual can make a difference and everyone should do their part. I do what I can. Here are my principles, and how I try to keep them:

• I respect and care for Earth and life in all its diversity.  Everything in the universe is connected to everything else and has value regardless of its worth to human beings.  In addition, with the right to own, manage, and use natural resources comes the duty to prevent environmental harm and to protect these resources for the future.
• We should protect and restore the integrity of Earth’s ecological systems, with special concern for biological diversity and the natural processes that sustain life. In my yard I have converted an acre of invasive species (bittersweet, Norway maple, Alianthus) into an acre of native trees and shrubs that provide food sources for birds. With the exception of poison ivy killer, I use no chemicals on my yard. The birds, bats, and dragonflies help control mosquitoes in my yard.
• I promote the recovery of endangered species and ecosystems. This can be seen in my lessons and teaching of science to high school students.
• We must manage the use of renewable resources such as water, soil, forest products, and marine life in ways that do not exceed rates of regeneration and that protect the health of the ecosystems.
• The goal of my life has been life-long learning of the knowledge, values, and skills needed for a sustainable way of life. In this regard, I have tried to provide others, particularly children and youth, with knowledge to empower them to contribute actively to sustainable development.
• It is my belief that every individual has the right to potable water, clean air, food security, uncontaminated soil, shelter, and safe sanitation. As a consumer I make a sincere and definite effort to buy products that are either manufactured in the U.S. or are certified as Fair Trade. Rather than shopping at Walmart, where products are cheap and poorly made and 91% are made in China, I spend the extra money to make purchases from local shops and small online boutiques. If at all possible (which is impossible for some electronics) I do NOT buy “made in China” products; China has an atrocious human rights (non-rights?) record and is the greatest polluter of the planet. As much as I am financially able to, I buy organically grown foods, including free-range chicken eggs and grass-fed beef. I also look for where the product has been grown and choose the one that has traveled the shortest distance, thus has a lower carbon (via transport) footprint.
• My daily intent is to treat all living beings with respect and consideration, and to promote a culture of nonviolence and peace.  “Peace” is the wholesomeness created by right relationships with oneself, other persons, other cultures, other life, Earth, and the larger whole of which all are a part. I do not always succeed, but it is always my intent and when I falter I just try again.

Biomes, oh Biomes

So recently in class we did a project on Biomes. We had to make a pretty little brochure and present it to the class. I had Temperate Grasslands which was fairly interesting and i liked learning about it. I certainly learned things I did not know previously. However, one thing about the project i did not like was that it seemed really rushed. It was very brief and the presentations were hardly memorable. Overall however, i think it was a fair project.

Biome Discussion

This biome discussion and research were very interesting, the biome that I did was the Hot Desert Biome. The ones that I was interested in were probably the Tropical Rainforest biome and the Deciduous forests. the tropical rain forest is very rainy usually and they apparently stay around 65 to 85 degrees all year round, while deciduous forests

( http://www.saburchill.com/chapters/chap00513f.html ) are cooler and have much different organisms living in it. Tropical forests have animals like tree frogs and what you would think of tropical creatures, while deciduous forests have organisms that would live in places like New England, which have bears and white-tailed deer. From my prospective I thought those two biomes were the most interesting, but of course the one I researched was also very interesting. This project was very interesting, but the only problem I saw with it was that people only really learned about the biome they were researching, also we did not have that much time to make these brochures.
