Elephant’s Toothpaste Mix two solutions together and you get an amazing eruption of foam. (Submit Review) Mix two solutions together and you get an amazing eruption of oxygen-filled foam that looks like a giant stream of toothpaste... or elephant toothpaste. The classic reaction is a favorite of chemistry teachers who have access to these chemicals that you will not find around the house.

others aren’t possible. Movement For living things to find energy/nutrients they have to interact with their surroundings‚ this is only possible if movement is able to happen. A plant will turn its leaves to the sun (phototropism): strands of xylem and phomen provide a skeleton like structure for the plant to grow towards the light source. Whilst a plant’s roots grow downward in response to the pull of gravity known as gravitropism. Nastic movement in plants do not involve growth and do not

Temperature range Background: All organisms are adapted to a particular environment with its characteristic temperature range. The temperature range allows the organism’s enzymes to control its metabolism by operating at their optimum efficiency within this range. Some organisms are adapted to live at high temperatures (80 - 100oC) and these are called thermophiles
