This is primarily a list of Greatest Mathematicians of the Past, but I use birth as an arbitrary cutoff, and two of the "Top " are still alive now.
Grate the lemon rind from 2 lemons into a large container or bucket. Grate the fresh ginger as well using the coarse teeth of the grater. Squeeze out the juice from about 6 lemons.
You will need ml. Add the juice to the mixture. Add the dried ginger, raisins and sugar. Add 1 litre of hot water not boiling and stir for about 3 minutes until the sugar has completely dissolved.
Add another 4 litres of warm water. Make sure the water is cool enough for you to hold a finger in it comfortably otherwise the yeast will die!
Sprinkle the sachet of dried yeast over the top of the water and leave it for a few minutes. Stir everything with a wooden spoon.
Pour the liquid into a large bottle and attach a balloon over the neck of the bottle. Secure the balloon to the neck with a thick rubber band. Place the bottle in a warm place but not in direct sunlight.
Let it stand for approximately 4 - 5 hours. When the raisins float to the top the ginger beer is ready to drink. Strain the liquid through a sieve. Make sure you work over a basin or similar area. Pour the ginger beer into clean clear glass bottles and add a raisin to each bottle. Make sure that you do not fill the bottles completely but leave at least 7 - 10 cm between the liquid and the top of the bottle's neck.
Attach a balloon to the necks of half of the bottles and secure these with rubber bands. Screw the lids onto the other half of the bottles. Store the bottles away from heat or sunlight. They do not need to be in a warm place. Leave it to stand overnight for at least 8 hours. Gentle unscrew the caps.
The gas inside will want to escape so do this slowly and carefully. What are the reactants in the reaction to make ginger beer? The chemical reaction occurs between sugar and fermenting fruit and the yeast. So the reactants are the sugar and fruit ginger and raisins.
What is the product in the reaction taking place in the ginger beer? The product is carbon dioxide and a very small amount of alcohol. Why are there fizzy bubbles in the ginger beer? It is the carbon dioxide gas that is was trapped in the liquid.
Where do you think the gas came from? It is a result of the chemical reaction between the yeast, the sugar and the fermenting fruit. Another example of where we see a chemical reaction taking place is when we burn wood in a fire, either in our homes or to cook food.Words in science are often used in different ways from ordinary English.
Completely different meanings even occur in different branches of physiology, e.g.
for the word "accommodation". followed by fermentation. Use formulas to write a chemical equation for cellular respiration. Label the formulas with the names of the compounds. + C6H 6C02 + 6H20 + Energy (oxygen) + (glucose) (carbon dioxide) + (water) + (Energy) Draw and label a .
The first resource is a simple worksheet that starts by asking pupils to label a forcemeter. The second part is a recording grid for pupils to write down how much different objects weight when they are .
Aerobic respiration (with oxygen) can produce 36 to 38 ATP molecules from each glucose molecule. Anaerobic respiration (without oxygen) only allows glycolysis to continue which produces 2 ATP molecules from each glucose molecule.
Therefore, aerobic respiration is some 19 times as efficient as anaerobic respiration. Cell Respiration Webquest Objective: Describe the function of, state the site and chemical equation for cellular respiration, and distinguish between anaerobic and aerobic respiration. Directions: Use the links provided throughout the quest to help answer the questions on a separate piece of paper.
