3 Teachers notes Establishing a tank of brine shrimps This is very straightforward, so don t worry! The best time to establish your tank is betweem April and September. Brine shrimp eggs are available from pet shops. First, obtain a glass or plastic tank. Make up saltwater (the amount will depend on the size of your tank), using a ratio of 30 35g of salt per litre of tapwater. Put some sand and fine gravel on the bottom of the tank, but only just enough to cover it. Brine shrimps feed on algae, so it is crucial to have good algal growth in the tank for two to three weeks before shrimp eggs are added. To get the algae growing, add one drop of a fertiliser per litre of saltwater. Put the tank on a south-facing window sill sunlight will encourage algal growth. Once the tank substrate and the water has a greenish colour (which, along with small bubbles of oxygen rising to the water surface, indicates the growth of algae), sprinkle the eggs onto the surface of the saltwater. Tiny shrimps (called nauplii) will hatch hours later, if the water temperature is C. It takes newly hatched shrimps about three weeks to reach the adult stage, at which point they will measure roughly 1cm long. It is helpful to stir the tank substrate once per week and particularly advantageous if you can get some substrate (three to four tablespoons) from an already well-established tank of brine shrimps. The addition of this substrate, with its algal and bacterial organisms, will generally ensure that the new tank gets off to a flying start.

6 Teachers notes Talking points This photocopiable offers suggestions for further talking points with lower and upper Key Stage 2 children. Ages 7 9 Why are most shrimps found in the lower third of the tank? Like most herbivores, brine shrimps eat regularly so must predict where food will be. For brine shrimps this is at the bottom of the tank or lake, although algae is also found suspended in the water. Adult brine shrimps are always able to find food if they swim down to the bottom. Adult shrimps also graze on the tank sides, but young shrimps feed on algae in the water. If the children were to repeat this experiment, what would be useful to add to a graduated cylinder, and why? Add substrate, to make the cylinder environment more like the tank. Two cylinders, one with substrate and one without, could be compared, side by side. Ages 9 11 Why have the brine shrimps shown a preference for the edge? Usually, brine shrimps are in the edge of the tank or lake. The ratio that spend time in the two areas varies but it is often around three or four: one in favour of the edge. In the wild, the edge is the shallow area at the lakeside. Shrimps prefer it because the water is shallower, warmer and more light penetrates, giving good conditions for algal growth. The edge may offer hiding places from bird predators, such as flamingos, although these birds concentrate their feeding on shrimp in shallow water. How might this observational study be developed? Two examples. Firstly, clean saltwater is not their natural habitat so shrimps may change their behaviour after a while and move away from the edge. Pupils may suggest putting substrate in one half of the dish, to see if it affects the ratio of shrimps in the edge and centre. Secondly, WORDS POLLY LEE, JOAN BOSWELL, DR MICHAEL DOCKERY the dish does not have a typical lake profile as its depth is constant. Tilt the dish slightly. Does that alter shrimp behaviour? Do other animals hug the edge of their containers or cages? Children could try this at home if they have a pet mammal, such as a mouse or gerbil. Mice and gerbils also hug the edge. (This is thought to be an anti-predator strategy and, in the wild, may also offer protection from the weather.) PHOTOCOPIABLE 8 LIFE PROCESSES APRIL 2007 JUNIOR EDUCATION TOPICS

17 Name < Glossary JOHN DAVIS, TEACHER AND FREELANCE WRITER Adaptation: The process of how a living thing changes to fit into its surroundings or environment and improves its chances of survival. Bacteria: Tiny single-celled organisms. Camouflage: Patterns, colours and shapes that disguise an animal so that it cannot be seen by predator or prey. Cells: The microscopic building blocks that make up all living things. Chlorophyll: A green colouring in a tree s leaves. It uses energy from the Sun to turn carbon dioxide, water and minerals into a type of food called sap. Cold-blooded: An animal that cannot generate or release its own body heat and relies on its surroundings for the regulation of its body temperature. Ecology: The study of the relationship between living things, and between living things and their environment. Ecosystem: A collection of living things and their environment. Examples can be as small as a pond or as big as a forest. Extinction: The dying out of the last member of a species. Food chain: A food pathway that connects several different species. On land, most food chains begin with a plant. Food web: A collection of interconnected food chains in a particular habitat. Habitat: The type of place a plant or animal lives in, such as a forest, mountain or desert. Invertebrates: An animal that does not have a backbone or bony skeleton. They include insects, crustaceans and molluscs. Metamorphosis: A change in body shape as a young animal develops into an adult. It is common in invertebrates and also in fish and amphibians. Migration: The movement of animals from one place where conditions are unsuitable, to another where they are, and back again. Organism: A living thing such as an animal or plant. Parasite: A living thing that lives on or in another species, known as its host. Photosynthesis: The process by which a plant makes its own food. It uses energy from the Sun to take carbon dioxide from the air and adds water and minerals from the soil to produce simple sugars. Vertebrates: An animal that has an internal bone structure and backbone or spine. Warm-blooded: An animal that can maintain a constant internal body temperature independent of its surroundings.
