LaptopBikeBag of rice Grams are tiny units, so we use them for light things like pencils and paperclips. Kilograms are bigger, so we use them for heavier objects like laptops, bikes, and rice bags.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A small pencil weighs only a few grams.
Pencils are tiny and light, so we measure them in grams, which is the small metric unit for weight.
2. A laptop is heavy, so we measure it in kilograms.
A laptop weighs a few pounds, which equals a few kilograms, the bigger metric weight unit.
3. One kilogram equals 1000 grams.
By definition, 1 kilogram is made of 1000 grams, so kilograms are used for heavier objects.
4. A paperclip weighs about 1 gram.
A standard paperclip weighs roughly one gram, which makes it a classic example of this small unit.
5. A bike weighs about 10 kilograms.
A kid bike weighs around 10 kilograms, so kilograms are the right metric unit for it.
Part C: True or False?
Read each statement. Circle True or False.
1. A feather would be measured in kilograms.
True False
Feathers are so light that grams fit them; kilograms are for heavier objects.
2. 1 kilogram is larger than 1 gram.
True False
Since 1 kilogram equals 1000 grams, a kilogram is much larger than a single gram.
3. Paperclips are usually weighed in kilograms.
True False
A paperclip weighs about one gram, so grams are the right unit, not kilograms.
4. A bike is best measured in kilograms.
True False
