Heavier and Lighter Worksheets

Helping students understand the concept of heavier and lighter is a unique one. We normally teaching topics that are better suited to one style of learning, but this is one that stretches the gamut. You want to be hands-on here, but not too much as you will want to help students use this concept in a more generalized setting. In order to help them achieve this stick with things that they are comfortable with and that they know very well. Students can use these worksheets and lessons to determine the relative weight of an object that is provided. We provide them with things that most students have a good level of experience with.

How to Judge What is Heavier or Lighter

Weight Scale

Visually, people and things can be deceptive. Especially in the case of their weights, one can find it very difficult to judge between two things and determine which one of them is heavier. In the case of people, it can be more difficult to guess the weight of someone. There can be people who look slim in appearance but weigh more than expected. Or there can be an opposite case as well. So, while making a comparison, how to judge who weighs more or less?

What makes things especially tricky regardless of the type of object we are discussing is the concept of density. Density is a measure of how tightly packed together an objects molecules are together. The tighter these things are packed together, the less space they take up. Some substances have very high densities and as a result a small amount can be very heavy. Other substances have very low densities, and the same size material could be very light. A really good example of this is the difference between gold and water. We are all familiar with a gallon container of water. You will see them often in the grocery store, they weigh about 8 1/3 pounds each. Water has a relatively low density. Gold, on the other hand, is very dense. So much so, that the same gallon container made of gold would weigh 160 pounds.

A common method of weighing things or people is to compare their weights with some commonly known weights. It is an easy way of finding out what weighs more and what weighs less. First, you make a known weight, a yardstick, and then you compare the weights of the other two things that you wanted to compare. For example, the average weight of a refrigerator is somewhere around 100 kg. Now, to determine the weight of two persons, one can make a comparison visually by making them stand next to a refrigerator.

If both of them have the same width, but one is a bit taller than the refrigerator, and the other one is a bit shorter, the taller person will weigh more. And by comparing their weights with that of the refrigerator, we will have an idea about their weights as well. It is one of the many ways through which one can judge who weighs more or less.
