I'll add my score here: 56 %. In my defense, Dutch education sucks; i've had only one year of basic physics/biology/chemistry, plus English isn't my native language.<br><br>The ones I missed:<br><br>2. Beans and coal both have stored energy. Where did the energy come from that is stored in beans and coal?<br>c. From the heat in the Earth's core. is not correct. The correct answer is:<br>b. From the Sun's light.<br>33 percent of students answered correctly.<br><br>I though since coal was mined, sunlight was incorrect. Shows what I know...<br><br>4. The Earth's Moon is<br>d. Sometimes closer to the Sun than it is to the Earth and sometimes closer to the Earth than it is to the Sun. is not correct. The correct answer is:<br>b. Always much closer to the Earth than it is to the Sun.<br>49 percent of students answered correctly.<br><br>I need more caffeine... I obviously know the sun is allways further out; I just didn't pay attention.<br><br>6. To keep a heavy box sliding across a carpeted floor at constant speed, a person must continually exert a force on the box. This force is used primarily to overcome which of the following forces?<br>d. The gravitational force exerted by the Earth on the box. is not correct. The correct answer is:<br>c. The frictional force exerted by the floor of the box.<br>52 percent of students answered correctly.<br><br>I thought the floor was tilted, therefore gravity exerts force on the box. Obviously, I missed the fact that the box wasn't been lifted up, but was sliding. <br><br>9. A 10-liter sample of CO2 gas contains the same number of molecules as how many liters of O2 gas at the same temperature and pressure?<br>a. 5 liters is not correct. The correct answer is:<br>b. 10 liters.<br>36 percent of students answered correctly.<br><br>Like I said, I had one year of chemistry. If I remember, CO2 means one carbon, two oxygen molecules, so if one has sets of three, and the other sets of two, then obviously, the container couldn't hold as many sets. I was obviously wrong.<br><br>So for me what it comes down to is: I don't pay as much attention [because I know this doesn't mean anything like a grade] And although I have a basic grasp of physics and chemistry, I lack the knowledge to adequately apply it.<br>
US Students continue to decline in basic sciences
<br>
... and um, those questions and answers were worded in such a way, as to piss people off, but i understood completely the mistake i made, after i relaized that they were the incorrect answers.<br><br>oh and those national results mean nothing, they just mean that with the huge increase in population, we also have a huge increase in stupid people. thats been a growing trend since people were invented.
