It's pretty unlikely you'll be wandering Paris in shorts - especially since you're used to such warm weather -- the oldtimers count mid-May as the final frost date! (sometimes it works that way, sometimes it doesn't -- but they publish garden advice to protect your plants until mid-May).
Dihydrogen Monoxide (DHMO) is a colorless and odorless chemical compound, also referred to by some as Dihydrogen Oxide, Hydrogen Hydroxide, Hydronium Hydroxide, or simply Hydric acid.
Students are asked to learn about the chemical by visiting the FAQ section of www.dhmo.org. As part of the assignment, students complete an acrostic assignment in which they write a factual statement about dihydrogen monoxide that starts with each of the letters of the term (see Figure 2).
