The moon’s gravitation force is determined by the mass and the size of the moon. Since the moon has significantly less mass than the Earth, it will not pull objects toward itself at the strength that Earth will. This means that if you went to the moon you would weigh…
Pied Piper, the fictional startup headed by a tech genius who created a revolutionary algorithm from Silicon Valley, doesn’t exist in real life. People in the real world are hard at work trying to rebuild the internet in a way that comes closer to its decentralized ideal. Pied Piper, which…
Hydrated copper(II) sulfate, CuSO4. 5H2 O(s), (HARMFUL, DANGEROUS FOR ENVIRONMENT) – see CLEAPSS Hazcard HC027c. The copper(II) sulfate should be provided as fine crystals. In this experiment students will measure the mass of hydrated copper(II) sulfate before and after heating and use mole calculations to find the formula. Would your…
Each point on the least-squares regression line represents the predicted y-value at the corresponding value of x. Looking for an answer to the question: Would it be reasonable to use the least squares regression line to predict the final exam score for ? Would it be reasonable to use the…
Presently, the moon does not have an internal magnetic field as it can be observed on Earth. However, there are localized regions on its surface up to several hundred kilometers in size where a very strong magnetic field prevails. This has been shown by measurements on rocks from the Apollo…
Calcite has more uses than almost any other mineral. It is used as a construction material (in the form of limestone and marble), pigment, agricultural soil treatment, pharmaceutical, acid neutralizer in the chemical industry and more. Calcite gemstone is a relatively soft gemstone and it can easily be scratched therefore…
There is a famous question often asked online: Would you rather fight a horse-sized duck or 100 duck-sized horses? For Wired Science blogger Rhett Allain, the answer is the horse-sized duck. Here, Rhett tells you how physics helped him select his adversary. President Obama’s handlers failed to alert their boss…

Scientists are extremely employable, make exciting discoveries and help solve huge global problems. Why would you not want to be involved? I have always wanted to be a scientist because there are few joys to compare to that of discovery. There is a wonderful thrill that comes from understanding … Would…
The rotation of our planet principally determines the length of the day. A faster rotation speed would mean a shorter day, so the number of days in a year would increase (provided that Earth still revolves at the same rate). What would happen if the Earth started rotating faster to…
