Welcome to Mr. Zepp's Wikispace Hompage.



NOTE: This wikispace web page is being phased out and replaced

Since our district moved to Google Apps, I have created new class specific WEBPAGES. The links are BELOW.

Questions

1) Potassium-40 is a radioactive isotope with an abundance of 0.012%. Bananas, on average, contain 422 mg of potassium (K). Calculate how many atoms of potassium-40 there are in a typical banana!

2) Seawater contains, on average, 0.10 to 2.0 mg/ton of gold, depending on location. Assuming the value is 1 mg/ton, how many gold atoms are there in a ton (2000 lbs) of seawater? How many atoms are there in a liter of seawater (assume the density of seawater is 1.0 g/mL and 1.0 kg = 2.2 lbs)?

The Scientific Method

In science, "fact" can only mean "confirmed to such a degree that it
would be perverse to withhold provisional assent." I suppose that apples
might start to rise tomorrow, but the possibility does not merit ... See More equal time in physics classrooms.
