Make your own metric balance scale.
Cut 8 pieces of cord into equal lengths.
Tie four strands together in a knot at the top and at the bottom to make a sling.



Cut the middle part out of the coat hanger and turn the hook sideways.

Be careful of sharp edges.
 Hang the hook on the edge of a table,
but place a piece of cardboard under the hook to protect the table.


 Hang one sling by one of the knots you tied on one hook and the other on the other hook.
Next place two small saucers that have the same weight in each sling.  (Use plastic!)

To find the mass of an apple, put the apple in one saucer. 
Then put nickels, pennies, paper clips, etc. in the other sauce
until both saucers are even with each other.

Experiment with small objects you find around your house. 
Keep a record of each item and its gram weight.
