Explain the concept and importance of biodiversity in tropical rainforests. Examine the causes and consequences of reduced biodiversity in this biome.
Part 1: Intro to Biodiversity
The sun supplies the overwhelming majority of energy
The energy is absorbed by plants through photosynthesis
It is then redistributed to other species through
The biosphere is the part of the earth where all living thing live.
All elements are directly or indirectly interdependent.
An ecosystem is an interdependent community of plants and animals together with the habitat to which they have adapted.
Organisms can be either producers or consumers:
Producers convert energy from the environment into carbon bonds
Plants are the most obvious examples of producers; plants take energy from sunlight and use it to convert carbon dioxide into glucose (or other sugars).
Another word for producers is autotrophs
Energy and nutrients are passed from organism to organism through the food chain as one organism eats another.
Decomposers remove the last energy from the remains of organisms.
Inorganic nutrients are cycled, energy is not.
Biodiversityis the biological diversity of all forms of life on earth: plants, animals and microorganisms. It refers to to species diversity, variations within species, interdependence of species, and habitat diversity.
Exercise: In groups, you will explain one of the following model. Create a (max) one page factsheet to share with the class
Sonaar Luthra demonstrates his quick and simple test to gauge if water is safe.
Engineer Michael Pritchard demonstrates his Lifesaver Bottle, capable of sterilizing dirty water in seconds. He believes that his invention could easily help meet the Millenium Development Goal of halving the number of people without access to safe drinking water by 2015.
What is one possible explanation for the dominance of black athletes in sprint events? Why is this a dangerous and/or erroneous assumption to make?
Write a blogpost explaining your understanding of the Nature VS Nurture debate. Using examples, give your opinion on the theme. Is our behaviour dictated by our genes or our environment? When you write about psychological studies, you must refer them by the name of the read researcher(s).
Using the Nature vs. Nurture (handout 1 and 2), read the arguments and then fill out the chart on the back, and check with your family tonight on whether or not they agree with you, and please bring your completed sheet for tomorrow’s class , ready to discuss your answers.
PART 2 – graphing results, analysis, conclusion and evaluation
Please use clear headings for these sections.
First you will graph your data in order to analyse your findings
* Note – Graphs can be computer generated or done by hand and must have titles, referred to and be integrated into the text, where you talk about them. You should use a variety of suitable graphs to display data. They must be clear, have labelled/numbered axis and titled. Be as creative as you want when illustrating all of your work.
Write your analysis under the headings of each Hypotheses. You will state what we expected with reference to our studies on coastal processes and landforms.( use what we have learned in class! ) You will analyse ( describe and explain ) the data you collected with regard to the expectations of a destructive beach, and state whether or not you have proved or disproved each hypothesis. DO NOT ANSWER THE RESEARCH QUESTION. You will do this in the conclusion.
The beach gradient is steeper towards the back of the beach
Create a beach profile by graphing the angle of slope from each quadrat of your transect and analyse this bearing in mind what we know about a destructive profile (use class averages)
Beach material will be larger and more angular towards the back of the beach
Create 1 graph to illustrate your findings roundness and size and analyse what you found. (use class averages )
The waves will be high ( 1 metre or more ) and frequent ( more than 12 per minute )
Using a table to illustrate the data and graph the 2 class averages..
There will be a strong longshore drift
Analyse your findings referring to prevailing wind, direction of movement and time taken for any movement of material over 10m. If it is over 3m per minute then it is considered strong.
5. There is natural evidence (erosional landforms) and evidence of Mitigation (man-made defences) which illustrate that show the beach is being destroyed.
Using a field sketch and the observational notes you made as well as photographs present any evidence of the above. Use lots of photos and be creative here. Annotate your photographs to show what they illustrate.
Sum up what you found. Are your hypotheses mainly proven or disproven? Go through each hypothesis and state whether it’s proved or disproved, based on the summary of your findings you will conclude and give your answer to the question: “ Is the beach at Kamakura Inmuragasaki a destructive beach?”
Briefly evaluate (discuss positive and negatives)
the methods and how these might have been improved (not the execution of your peers!)
suggest how the study/methodology might be improved
I will be in Kamakura today, conducting fieldwork with the grade 10 InS class. Here is your work:
10 minutes to prepare your presentations
Once the presentations are done sit around the table at the centre of the room.
You will now have a 15 minute (or longer if the conversation is good) socratic seminar ( open discussion where each comment must be supported by a fact you have researched) answering the following IB-style questions:
“The causes of global climatic change are essentially human.” Discuss this statement.
“Global climate change will increase disparities in development.” Discuss this statement, referring to examples.
