ENIGMAMODERATELY DIFFICULT

What should the next diagram in this sequence look like?

TREASURESDIFFICULT

Can you locate 12 hidden treasures

in the empty cells of this grid? The

numbers outside indicate how many

treasures there are in each row or

column. Each arrow points directly

toward one or more of the treasures –

and does not share a cell with one. An

arrow may be immediately next to a

treasure it points to, or it may be farther

away. Not every treasure will necessarily

have an arrow pointing to it.

A WEIGHTY MATTEREASY

The mass of an object in kilograms (kg) stays the same no

matter where it is, but its weight in newtons (N) changes

along with gravitational conditions. On earth, Mari weighs

686 N and has a mass of 70 kg. Her German shepherd,

Chip, weighs 343 N with a mass of 35 kg. On Mars, they

each weigh 38 per cent of their earth weight. On the

moon, they each weigh 16 per cent of it. Which one

weighs more: Mari on the moon or Chip on Mars?

Bonus: Which one has the most mass?
