Ocean Acidification

Ocean Acidification | Chemistry - How can chemistry affect our world? | Scoop.it
Lisa Gan's insight:

The Acid Ocean site by VirtualUrchin is a very content heavy flash site that guides students through the phenomena of ocean acidification and the science behind it. As you make your way through the source you are introduced to the basics (such as pH etc.) before guiding you through the chemistry behind ocean acidification. Scattered through the site are short activities (such as ranking substances by their pH) that allow the student to learn through first hand practise. At the end of the flash site the students are presented with a summary as well as being introduced to the idea of modelling the concepts in a science lab.

 

Despite this source requiring quite an extensive base knowledge of chemistry I feel its a good source for addressing the science behind the concept of ocean acidification. It builds up towards the more difficult scientific concepts by building a foundation of knowledge for the students. In order to use this source to its full potential students will require background knowledge in chemistry and acid/base interactions. It would be best to use this source as a collective class rather than individually as this would allow the teacher to guide the students through all the information being presented. 

 

Overall this source has its advantages and disadvantages of use. By presenting this resource to the class as a whole the teacher has the advantage of being able to guide the students and explain the concepts using the resource to demonstrate the steps involved in ocean acidification. Students would otherwise find this resource quite challenging to do individually, resulting in it being quite a time consuming activity to perform in the classroom.

Footprint calculator
Lisa Gan's insight:

The carbon footprint calculator developed by the World Wildlife Foundation (WWF) is a simple representation of an individual's carbon footprint. The simple flash quiz has students input either simple or more detailed data about an individual's food/gas/electricity consumption etc. and then uses this information to develop data on an individual's impact on the environment and the earth. 

 

I found the resource very simple to use, and well suited for students studying climate change. By developing their individual carbon footprints a student may be able to better relate to the subject matter and develop a more concrete understanding of just how an individual's actions can affect the health of our atmosphere. In a classroom I feel the resource would be well suited to an ICT lesson, where students are able to develop their personal carbon footprints. They could further develop their understanding of just what their carbon footprint means by further researching some of the data considered during calculation (e.g. the effects of transportation, agriculture, electricity etc.)

 

The calculator doesn't seem to require any particularly high level of prior knowledge of scientific literacy, terms used are simple and readily understandable. It would be well-suited to introducing a topic on climate change by making it relatable to each individual student, prior to developing the science associated with the phenomena.

Free Online Energy Games Using Alternative Energy Souces For Kids

Free Online Energy Games Using Alternative Energy Souces For Kids | Chemistry - How can chemistry affect our world? | Scoop.it
Visit different locations around the world & implement the best alternative energy sources including wind, hydro, tidal, geothermal & solar
Lisa Gan's insight:

Wonderville's "Save the World" game is a simple, interactive way for students to develop their knowledge of alternative energy sources. They set up a scenario where the world's energy supplies are in crisis and you are in the position to implement alternative energy sources in order to provide each area with the required amount of energy. 

 

After completing each area a short animation describing the energy source and how it works comes up; if any information is misunderstood or misheard during the animation students are provided with the ability to go back over the points covered. 

 

I found the resource to be a helpful way of introducing students to alternative energy sources; a point I feel should be addressed while investigating the effects of polution, climate change etc. on the environment. It is engaging, and can be used in conjunction with other activities or worksheets to cement the information gained. The scientific literacy required to fully understand the site is fairly low, however there are some terms that may benefit from prior development in knowledge such as glossaries.

 

Prior to using this resource, I feel it would be best to introduce students to climate change and the detrimental environmental effects (as well as what causes these effects). This game would be suited to help students develop potential solutions to our increasing environmental problems.

Seafood Buffet

Seafood Buffet | Chemistry - How can chemistry affect our world? | Scoop.it
Lisa Gan's insight:

This interactive flash site introduces the students to some of the organisms who may face the effects of ocean acidification and climate change. 

 

Students explore the image, clicking on different organisms (e.g. the lobster, the girl, the fish in the tank) in order to bring up a dialogue box with information on the individual organism (e.g. its role in climate change, the effect of ocean acidification on the organism etc.)

 

This interactive site is a simple means for students to develop a knowledge of the living organisms effected by climate change, as well as potentially developing a food web that allows them to see the effects ocean acidification has on society, even if it isn't first hand. I would use this source to help students develop their understanding of the relationship between everything on our planet and how something that they may not believe impacts them can have ripple effets on their own lives. 

 

Overall I think the source is an effective and engaging tool that allows students to explore the effects of ocean acidification at their own pace. It is quite wordy at times, and requires some prior understanding of some scientific terms (e.g. acidification, carbon dioxide, pH, saturation etc.) so in terms of sequencing I would likely use this source once students have developed their understanding of acid/base chemistry. It may also require some focus on literacy and numeracy in order to fully comprehend some of the information being addressed.

Climate Change

In which Hank details the five scariest things that will likely happen because of climate change. Follow SciShow on Twitter: http://www.twitter.com/scishow L...
Lisa Gan's insight:

SciShow has a wide range of educational videos suited for both students and adults. This video focusses on Climate Change, and five things that will likely happen because of climate change. 

 

This video is quite long but I feel it is a great introduction to the effects of climate change. The teacher can then build upon some of the effects addressed in regards to why and how they occur, and the potential for management or even reversal of the effects occuring. As a resource, I feel the video is a great start for promoting discussion in the classroom, perhaps using group brainstorming to develop some of the ideas adressed in the video. 

 

In terms of it's appropriate use in the classroom, I feel the video would be better suited to a year 9 or 10 class, if not older. It requires a somewhat more developed scientific literacy in order to fully understand some of the content. Perhaps prior activities to develop literacy could be employed (e.g. Reading tasks with newspaper articles or websites devoted to climate change or the effects of climate change.) 

 

I personally believe this is a strong resource, highlighting the effects of climate change succinctly, and providing a good foundation on which to develop students' understanding of the effects of climate change. However, it can be considered quite challenging material to understand and may require quite a large amount of knowledge development in order to fully understand the content being presented.
