I would suppose it is referencing and mimicking the movements of a scale/balance which moves its own arms when the mass is being taken; lighter objects would be higher and heavier objects lower, movements which can be gestured using one's own hands.
To use real objects in teaching, one should use them as examples. If a person is trying to teach about bugs, use an actual bug. This can help with hands on learning.
the pollen might stick to their clothes, hands/fingers and hair, which can be an easy source to find out where the person has been.
Assuming the fingers are in contact to push or pull the object, the amount of pressure put on the fingers to move an object would increase with the weight of the object. This results because friction force that must be overcome to push or pull the object is proportional to the object's weight. [Elementary physics.] And the print definition varies with the pressure used to implant the fingerprint. If the fingers are not pressed hard enough against the object, some of the print will be missing from the object. If they are pressed too hard, the print will be smudged and ill-defined. And that's the answer. Fingerprints are likely to be smudged with moving heavy objects, missing in part with moving light objects, and better defined when moving medium weight objects. All this assumes we're using the fingers in all cases. In fact, we'd probably use the palms of our hands if we are moving heavy objects; so the fingers might not even touch the object.
There are several printed signs in a laboratory that ask for hands to be washed upon entering and leaving the lab. There are also signs that display a person at a sink washing their hands.
They are generally used to hold objects like a small bowl that would be heated by something like a Bunsen burner, the bowl would be too hot to hold with hands.
A simile is a sentence comparing two or more objects by using the words "like" or "as." An example would be to say "Her hands were as clammy as a fish," or "His hair was as red as fire."
It is important to use potholders when holding hot objects to prevent burns to the hands.
Tools or their hands.
Heat, acid, sharp objects, blunt force trauma to the hands.
Kafooty means to keep your hands and other objects to your self and to respect like all of the character traits! KHFOOTY = "Keep Hands, Feet and Other Objects To Yourself"
They believe in harsh discipline and don't feel their bare hands can hit children hard enough like objects can.
the answer is hands wax and other objects
It is important to use potholders when holding hot objects to prevent burns to the hands.
It depends on how you define "hands". Cats do not have opposable thumbs; however, cats do use their front paws to manipulate objects.
Mittens
so animals can use their hands to hold or grab objects
Washing your hands or washing dirty objects by hand.
