ANTS

WRITE A QUESTION

TURN TALK AND

WRITE DOWN YOUR GUESS IF YOU TOOK ALL THE ANTS IN THE WORLD AND COMPARED THEM TO ALL THE HUMANS, WHICH WOULD WEIGH MORE?

How Many Ants are there? Part 1: The BBC article writes “British entomologist C.B Williams calculated that the number of insects alive on earth at a given moment was one million trillion. Write this number in scientific notation. Part 2: If 1% of the insect population consists of ants, how many ants would there be? Show your work. Part 3: In the The BBC Four documentary, one claim for the number of ants is 100 trillion. Write this number in scientific notation. Part 4: So, how many ants do you think there are? Give a reasonable range below. High Estimate: Low Estimate:

How much do the ants weigh? Read the three quotes from the BBC article below and address the synthesis question at the bottom of the page. QUOTE 1: Individual workers weigh on average between 1 to 5 mg, according to the species. QUOTE 2: The common ants which live in British gardens weigh about 1mg or 2mg. QUOTE 3: It's probable their weights vary greatly - though most experts seem to agree the average weight of an ant is less than 10mg. Synthesis Question: Use all of the information given so far to construct a reasonable estimate for the total weight of all ants on Earth. Include a high number, low number and best estimate.

How much do all the humans weigh? Average Human Adult = 62 kilograms. Write this number in scientific notation.
