U key reasoning 2 3 our glass objects are shown: a measuring cylinder, a test tube, a round bottom flask and a funnel. raduations (marks), which are only on the measuring cylinder, allow different amounts of water to be measured accurately. bserve the diagram carefully: the eyes are at the end of the long tentacles. he column (bar) graph that represents the number of backbones is a little under, so () is the best answer. U asy asy asy 4 5 6 7 8 9 ptions, and all contain the three coloured minerals showing in the block, but only option () has the black line crossing the layers of the brown mineral and the three minerals in the correct sequence. he teacher explained that when a plastic bag was placed over a plant, the water that formed on the inside of the plastic bag had come from the plant. or the test to show that water came from the soil in the same manner, the water must form inside the plastic bag over the pot with soil in it (pot ), and water must not form inside the plastic bag over the pot with no soil in it (pot ). s all drops were the same measured size, the fastest spreading liquid would wet the biggest area of paper. his would be the liquid that was best absorbed by the paper. ater has the biggest wet area. ote that there are two scales, one for the nail and another for the graph. he nail is 4.5 cm long. he end of column is in line with the end of the nail but the graph scale indicates that the column is only 2 cm long, and so column is wrong. olumn is 5 cm long and column is almost 8 cm long, so they are both wrong. here are four string phones. rom the diagram, the far left phone is the best phone. t is short, it has a tight string and large cans. he students tested which phone worked best by changing the length of the string, the tightness of the string and the size of the cans. ptions, and describe the variables that the student changed in the test(s). ption describes the variable that needed to stay the same. s the shadows of the trees, buildings and walls are toward the bottom left hand corner, the un must be toward the top right hand corner. s this is early morning and the un rises in the east, the top right hand corner must be east. edium edium edium edium ediumard ediumard ard cience ractice uestions aper
