year 8 BIOLOGY TOPICS

In Year 8 Biology you will learn about how and why we breathe and how our bodies are supplied with energy. You will learn about microscopic organisms and how many organisms interact together with their environment.
8B Respiration
8c microbes and disease
8d ecological relationships

8a food and digestion

Here are the learning objectives for this topic

I can
o Name the 7 nutrients that humans need
o Give an example of a food or drink that is a good source of that nutrient
o Name some problems caused when we don’t eat a balanced diet
o Name the 4 different types of teeth we have
o Name one enzyme
o Label a diagram of the digestive system

I understand
o Why we need to eat each of the 7 nutrients
o That different teeth have different jobs
o Why brushing teeth is important
o What an enzyme is
o How enzymes work
o Why enzymes are important in digestion
o What happens to food in each organ of the digestive system


USEFUL digestion WEBSITES

Look at the bitesize activity but focus only on the food part (it is also about drugs which is Year 9)

Look at the bitesize pages for nutrients, diet, the digestive system and enzymes.

Try Doc Brown´s quiz.

Label the digestive system on the CGP books website.

Learn about enzymes on skoool.co.uk (a bit harder than Year 8 level)

Have a look forward to IGCSE Units B3 and B4 as well as the B4 Photosynthesis unit.
