Beetroot Beetroot is a brilliantly versatile veggie. There are many ways to eat it including the traditional pickled beetroot but also more modern recipes such as marinated beetroot with grilled goat’s cheese and creamy beetroot risotto. To grow beetroot‚ sow 2 seeds every 10cm (4 inches) into a 2cm (0.75inch) deep trench. The children will enjoy using a stick to make the trench

CORE PRACTICAL ONE Describe how the effect of caffeine on heart rate in Daphnia can be investigated practically‚ and discuss whether there are ethical issues in the use of invertebrates. Daphnia‚ the water flea‚ is a small freshwater crustacean which lacks physiological methods of maintaining a constant body temperature. This means that if the environmental temperature changes‚ its body temperature does so too and its metabolic rate will be expected to rise or fall accordingly. So the temperature

The results produce a graph with negative correlation‚ a curve that has a negative gradient. The graph shows that as the temperature is increased‚ the colorimeter reading is decreased.

Background An indicator is a halochromic chemical compound that is added to a solution to determine its pH. It is a chemical detector for hydronium ions. The indicator changes colour to show the pH of the solution. Some indicates are not very precise and only tell us whether the solution is acidic or basic. When the indicator is added to the solution‚ they bind to hydrogen or hydroxide ions. The different electron configurations of the bound indicator cause the indicator ’s colour to change.
