Talja [164]

Answer:

1) IV: The quantity of salt added

DV: The resultant density of the salinated water

Hypothesis: The egg will float when the mass of the volume of the salinated solution displaced by the egg is equal to or larger than the mass of the egg

2) IV: The extension of the rubber band above original length in centimetres

DV: The distance flown by the rubber band

Hypothesis: The potential energy stored in the rubber band by pulling will be transformed into kinetic energy and the larger the extension, the larger the stored potential energy, and the larger the resultant kinetic energy, the higher the velocity and the further the distance flown

3) IV: The wing span of a paper airplane

DV: The distance flown by the plane

Hypothesis; The glide of the airplane is a factor of the wings span increased wingspan increased glide and increased travel distance

4) IV: Presence of more light

DV: Height to which plant grows

Hypothesis: Photosynthesis, which is the conversion of carbon dioxide and water into glucose and oxygen in the presence of Sunlight is essential for plant growth and the more the presence on light is increases the higher plant will tend to grow

5) IV: Amount of vinegar in the canister

DV: The height a rocket will launch

Hypothesis: With a given amount of baking soda, in the canister a little amount of vinegar causes a delayed launch but an increased build up of carbon dioxide resulting in higher height reached than when more vinegar is used in which case the lift off will be more rapid but the power will be lesser and the height reached reduced

6: IV: Surface area of the coin

DV: The number of drops held

Hypothesis: Due to surface tension and cohesion which are properties that increase with surface area and as such a coin with a larger surface area holds more water drops

7. IV: Number of hours of study

DV: Science score

Hypothesis: A student science scores is directly related to the amount of science topics thought the student is able to respond to in a test and it is directly proportional to the amount of study the student has done related to the science topics

Using two or more sentences, describe how a light microscope creates a magnified image.

a_sh-v [17]

Answer: A microscope is an instrument that produces a clear magnified image of an object viewed through it. A microscope must be able not only to magnify objects sufficiently but also to resolve, or separate, the fine details of the object that are of interest to the viewer. In the optical microscope visible light rays, reflected from or transmitted by the viewed object, pass through a series of lenses and form an enlarged image of the object. This image is produced at the normal distance of clearest vision, which is about 10 inches, or 25 centimetres, from the eye of the viewer.
