This page contains all the challenges I have used in my classroom that are mentioned in the blog posts. Enjoy!
Challenge 1
Q: A person uses on average 80 gallons of water a day!
Astronauts on the International Space Station (ISS) use only 3 gallons of water
a day! Compare the two numbers. What percent of 80 gallons of water does an
astronaut use? Convert the percent to a decimal and a fraction. Create a
diagram of the fraction.
A: 3/80 = 0.0375
0.0375 x 100 = 3.75
3.75% of water
3.75gallons / 80 gallons
Challenge 2
Q: The following gases are found in Earth's atmosphere: Argon, Neon,
Carbon Dioxide, Nitrogen, Methane, Nitrous Oxide, Helium, Oxygen, Water
Vapor, and Ozone. Select 5 gases that you think are the biggest percent
to make up the atmosphere. Create a bar graph of the percentages of each
of the 5 gases you pick. The total does not have to equal 100%. Ex:
Neon = 20%; Nitrogen = 15%; Oxygen = 10%; Oxide = 5%; Helium = 1%
A: Nitrogen 78% Oxygen 20% Argon 0.9% Carbon Dioxide 0.03% Neon 0.001%
