Learning Intention: Students will understand the relevance of specific chemical reactions to everyday life and be able to describe the usefulness of those reactions to society.
Success criteria: Students will produce a poster, slideshow or video that investigates and describes a specific chemical reaction and it’s usefulness in our lives.
Your task is to research one of the following materials and how they can react to produce useful results – a release of heat, a new product or a portable source of energy for example. Find out how these materials are extracted or produced, the useful reaction that occurs and how this reaction benefits society. Are their any disadvantages of this reaction? (eg. greenhouse gases produced, finite resources being used or toxic by-products?
This project is due next Monday, 14th May and will be assessed for your end of term report.

Learning Intention: Students will understand the meaning of exothermic and endothermic reactions.
Success Criteria: Students will be able to identify exothermic and endothermic reactions and give examples of each. They will be able to explain why these processes to considered to be exothermic or endothermic.
Endothermic reactions absorb energy, causing a decrease in temperature (eg. photosynthesis, melting and evaporation all require energy to be added to the system). Exothermic reactions release energy, causing an increase in temperature (Combustion, freezing, and condensation release energy from the system).
Mr Kent’s Chemistry page has some excellent examples of exothermic and endothermic processes and chemical reactions. We will be conducting four experiments in class and measuring the temperature change to determine which are endothermic and which are exothermic reactions. Leave comment below about what you found from your experiments. Can you think of any examples of exothermic and endothermic processes from home?
Learning Intention: Students will understand that the different properties of substances allow them to be separated in different ways – particle size, density, magnetism etc.
Success Criteria: Students will be able to identify 10 different methods of separation and give an example of each. They will be able to draw a flow chart to separate a mixture of sand, salt, rice and iron filings.
This term in Year 7 Science you will be starting a unit of work on Separating mixtures. You will be learning about the following processes and how they are used when separating mixtures:
Can you think of some examples of how these methods are used in the home and in the workplace? At the end of this unit of work you will be asked to separate a mixture of salt, sand, rice and iron filings. Download a worksheet to check your understanding of the definitions for each of these processes here: Separating Mixtures worksheet

So far this term we have done lots of experiments to demonstrate the properties of different materials, such as:
Well done Sarah and Emma for making their own homemade cosmetics – an exfoliating gel with poppy seeds and a shampoo from an emulsion of honey and egg yolk. The image above is from Quizlet, where you can create your own flashcards, scatter games and other activities to assist you to remember the improtant terms and definitions for this unit of work.
Materials scientists are constantly working on innovations to improve the manufacture and use of fabrics, structural materials and packaging. This article, from Web Urbanist, describe “8 Substances that will shape the future“.
While I am on Year 7 camp at Roses Gap (19th to 21st March) those Year 9 students not on the Advance camp should be studying for their science test. This test will be on Friday 23rd March and include all the work we have done this term. You should read your text book chapter and write some study notes as well as review your workbook with the practical experiments we have completed.
Welcome back to school for another fabulous year of science and learning! Please bookmark this site for future reference as this will be the starting point for all our science studies during the year. Our first unit of work will build on your knowledge of matter, atoms and molecules, elements and compounds and chemical reactions.
Learning Intention:
(1) Students will understand that all matter is made of atoms which are composed of protons, neutrons and electrons; natural radioactivity arises from the decay of nuclei in atoms.
(2) They will know that chemical reactions involve rearranging atoms to form new substances; during a chemical reaction, mass is not created or destroyed.
(3) Students will understand chemical reactions, including combustion and the reactions of acids, are important in both non-living and living systems and involve energy transfer.
Isn’t this a great infographic about Smallpox? It came from AJC1 at FlickrCC
Your task is to research a disease of your choice and answer the following questions in your own words:
1. Is it infectious/contagious?
2. What are the symptoms of this disease?
3. What causes the disease?
4. Is it spread by vectors?
4. How is the disease treated?
5. How can the disease be prevented?
Create a slideshow about the disease, adding creative commons images from Search Creative Commons or Flickr Creative Commons (be sure to select Creative Commons images only).
Make sure you have a Title slide with your first name only and the topic of study and a page for all your References at the end. Then upload your slideshow to Slideshare and embed the slideshow into a post on your blog.
The last step is to send me an email with the link to your blog post. Daniel has done each of these steps and can explain to you how to do it, or perhaps Mrs Davey can help you in ICT. This is Daniel’s project on pulpy kidney, a disease in sheep, goats and cattle:

The school is trialling a new source of information resources, online databases and eLearning modules, that I would like you to test out. Please access http://fofweb.com/demo and I will let you know the username and password. Go to the Medical and Health section, just below the science links and search for your disease.
Also, try the ebooks at http://ebooks.infobasepublishing.com, (same username and password) which has a range of digital enyclopedias for you to search for your information.
Fifteen minutes before the bell goes, I would like you answer the following questions in a comment on this post:
1. What are the advantages of using these types of digital resources over a Google Search?
2. What are the advantages of using these types of resources over similar non-fiction books in the library?
3. Are there disadvantages of using online databases and ebooks? Explain.
4. Did you like using these resources? How did you find getting the information – easy, medium, difficult?
5. Would you recommend that the school purchase these resources, basd on your experience?

Learning Intention: To understand how technology has contributed to our knowledge of our solar system and beyond and to be able to describe the characteristics of planets and other objects in space.
Success Criteria: You will be able to list and describe our sun and it’s terrestrial planets and gas giants, as well as asteroids, comets, meteorites and other space objects. You will be able to list and describe some of the inventions and equipment that has enabled us to probe space and gather and send back data.
We are starting a new unit of work, looking at our Solar System, which consists of our nearest star (the Sun) and the eight planets that orbit it. Your first task is to list as many different space-related objects from the picture above, that you know the names of. Then go to this scavenger hunt and download the questions. You will find the answers at the Solar Systems and Planets page at the Science.spot KidZone. You may also find some answers at The Nine Planets; “Our Solar System” and “Amazing Space”
When you have finished these directed questions, you are asked to produce a digital product that answers one of the following open-ended questions:
1. How has technology contributed to human understanding of how the earth formed and our planet in relation to the solar system? Make sure you describe some of the inventions that have helped us to discover more about the planets.
2. What do you think would be required to make it possible for humans to survive on other planets? Make sure you describe the environmental conditions on at least two different planets.
Your work can be presented as a slideshow, video, e-poster or magazine article. Please leave a comment on this post with a link to your blog where you have embedded your Slideshow using Slideshare.
