Year 8 Diseases Project

online_databases

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?

Year 8 Nutrition

Nutrition_mindmap_JG
James’ Mindmap using Bubbl.us and Clipart.

Your first task today is to create either a Bubbl.us (or paper) Mindmap or a (virtual or real) Poster reviewing what we learnt yesterday. The title is Nutrition and you need to include each of the five nutrients, with what they are made up of, why they are needed and at least five examples of each food type. Post your finished product on your blog and send the link to my gmail address. When you have finished check out this activity from BBC Bitesize: Nutrition.

Nutritional Information panels contain data about the amount of energy (measured in kilojoules), carbohydrates, proteins, lipids, vitamins and minerals in packaged food. They are compulsory in Australia and give consumers information about their the food they are purchasing and consuming. You will have a variety of packages to read, interpret and record the data in the Google Document at this link:

Nutritional Information of Food Products

This is an interesting interactive from PBS that demonstrates how different nutrients are used in your body.

Next week, while you are on camp, I would like you to keep a food diary, to work out how many kilojoules you consume each day. For each day, you need to record the quantity and type of each food you eat for breakfast, lunch, dinner and snacks. When you get back from Apollo Bay, we will do some food tests to investigate what types of nutrients are in different foods, so make sure you bring in a small sample of food to test. These are the tests we will be doing:

1.Brown paper or Emulsion test for fats and oils (lipids).
2.Iodine test for starch.
3.Benedict’s solution and heat for glucose (sugar).
4.Copper sulphate (10 drops) and sodium hydroxide (5 drops) for protein.
