Why is science important?
in pairs. Which of the following latest scientific discoveries 1 Discuss do you think is the most important? Why? VV Initiative to grow organs and regenerate human tissue. VV Scientists discovered an alien planet that’s the best candidate for life. VV Scientists found a new continent under the sea in the South Pacific.
at the instructions for two scientifc experiments, A and B, 2 Look and answer the question. In your opinion, which set of instructions is easier to read? Consider the following elements: the way the information is arranged, (paragraph vs list), the use of pictures and the use of graphic elements (bullets, pictures, or numbers). A B Materials 2 plant pots with garden soil one package of plant seeds
pots: (pl. n.) a container, usually round. funnel: (n) an object with a wide round opening at the top, and a narrow tube at the bottom used for pouring liquids into containers. seeds: (pl. n.) a small, round, or oval object produced by a plant and from which a new plant can grow.
Materials 2 spray bottles with water lemon juice
Place several seeds in soil. Label one pot “acid” and the other one “normal”. Water both pots and put them under direct sunlight. Water each pot until each plant has a sprout with leaves. Choose one spray bottle and add lemon juice (5 drops of lemon juice per one liter of water). Water each plant as usual and then spray each plant with the acid mix or normal water as labeled. On the 14th day measure both plants and compare their aspect.
plastic bottle vinegar small balloon
funnel teaspoon of baking soda
ss First, fill the bottle halfway with vinegar and stretch the balloon as if you were to blow it up. ss Then, use the funnel to put the baking soda inside the balloon and shake it gently until all the baking soda goes to the bottom. ss Next, stretch the opening of the balloon until it’s completely over the opening of the bottle. ss After that, lift the rest of the balloon so that the baking soda falls into the vinegar. ss Finally, watch the balloon inflate!
