Food and what's in it: focus on carbohydrates, proteins and fats
- Biological compounds activity - Interactive animation that starts with an an overview of what is in the organic molecules of proteins, carbohydrates and fats (and then goes onto carbon, oxygen and nitrogen cycles, which is useful for the Micro-organisms topic).
- Body needs - Are you what you eat? A flash mouse-over animation to investigate your nutritional requirements. Includes details of what you get if you don’t get enough of particular nutrients. Focus on carbohydrates, proteins, lipids
- Diet and Digestion - Includes what’s in food, a nice diagram of the digestive system, an animation of peristalsis and a wee bit about physical and chemical digestion. Has an easy and a hard Test Bite at the end.
Organs in the digestive system (mostly in order of usefulness)
- Digestion - This interactive e-source about food groups and the digestive system allows you to complete summary sheets to check your progress as you go, and there’s a quiz at the end too. Really quite a good overview, so highly recommended.
- Organs of digestion - animation with good step-by-step descriptions of wha's going on in each organ as food moves through. Was one that went with an activity in your booklet.
- The digestive system - Short animated movie with narration.
- The real deal on the digestive system - An informative and easy to understand article that leads you through the organs involved. Updated June 2010. Has an animated diagram for a very basic review of structures and functions on page 1.
- Food processing - Interactive showing basic processes in a highly no-scientific manner. Good reminder about what is digested where, and how, and by what, though. Pretty basic!
- Diet, drugs and health - Very basic overview, maybe even too basic? This Revision Bite covers: Nutrients; Some effects of a poor diet; Digestive system; Digestion and enzymes; Absorption and egestion (plus more).
- The Digestion and Absorption of Fats - Step-through or narrated animation. Warning: Pretty complex and thorough, but shows absorption nicely, and includes villi. Shows roles of bile and lipase acting on fat molecules too.
Enzymes and digestion
- Enzymes and their uses - Text resource with a few diagrams and animations about enzymes. (Not very interactive!) Includes: Enzymes; Types of enzymes; Enzymes in digestion; The properties of enzymes; How do enzymes work?; Effect of temperature and pH; Uses of enzymes; Immobilised enzymes
- Enzymes - Enzymes in general and their role in digestion too. Test Bites for both.
After food has been absorbed
- Circulation - about the heart and blood vessels, briefly. Not specific to transporting nutrients.
- Life Processes – Respiration and the role of lungs - A quick text overview of respiration and how the lungs are involved. See pages 3, 4 and 5 only. (The rest reviews muscles and bones). Bit much detail on lungs, but a couple of nice animations showing the exchange of CO2 and O2.
- Insulin and Glucose Regulation - How hormones from the pancreas regulate the level of sugars in the blood after and between meals. An 'Extra for experts', definitely.
- A Cow's Digestive System - Explanation of rumination in the first chambers of a cow’s stomach, with animation and narration (as embedded above) 1:35
- Skull science - How the skull shape and teeth relate to the diet of various mammals. A brochure-type resource.
