INFO SHEET - The human digestive system - The human digestive system consists of a long muscular tube and several accessory organs such as the salivary glands, pancreas and gall bladder. It is responsible for food ingestion and digestion, absorption of digestion products and the elimination of undigested materials.
TEACHER RESOURCES - Seeds, Stems and Spores - A plant reproduction resource for NZ Curriculum levels 1 and 2. Explore some of the science ideas behind plant life cycles, seed dispersal and how some plants reproduce without seeds.
New Zealand’s unique ecology - New Zealand has a rich and unique range of plants, animals and fungi. The level of distinctive biodiversity is as high as such world-renowned ecosystems as the Galapagos Islands. So how have our unique ecosystems developed?
TEACHER RESOURCES - Pollination - Learn about the role of flowers in the life cycles of flowering plants. Discover how flowers ensure the transfer of pollen, and meet some of the unsuspecting animal pollinators.
ANIMATION - The digestive system plays a critical role in breaking down large food molecules into smaller readily absorbable units. This animation details how food is processed as it moves through the digestive system.
INFO SHEET - Hidden heat - Converting a liquid at its boiling point to a gas at the same temperature requires an input of heat energy. The reverse process releases heat energy. This ‘hidden heat’ is called ‘latent heat’.
INFO SHEET - Reflection of light – Specular reflection is when light hits a smooth surface and bounces off at the same angle. Diffuse reflection and scattering are when light reflects off rough surfaces and travels in many directions.
INFO SHEET - Greenhouse effect – The greenhouse effect is the natural warming of the Earth’s atmosphere. Solar radiation enters the atmosphere mainly as light, and some of that radiation is absorbed by the Earth’s surface then changed to heat that is reradiated into the atmosphere where it is absorbed by greenhouse gases then reradiated back to Earth again.
