Weight tells us how heavy or light something is. We use a tool called a scale to find out how much things weigh. We measure weight in pounds (lb) or kilograms (kg). For example, a loaf of bread weighs about 1 pound, a dollar bill weighs about 1 gram, and a pineapple weighs about 1 kilogram. Did you know that 1 kilogram is the same as 1,000 grams? Also, 1 kilogram is about 2 pounds!
We can guess how much something weighs and then check our guess with a balance scale. Let’s try it! Imagine a dog. Do you think it weighs more or less than 1 pound? Since a dog is bigger than a loaf of bread, it probably weighs more than 1 pound. If we put the dog and the loaf of bread on a balance scale, the side with the dog would go lower, showing it weighs more.
Now, think about a paperclip. Is it more or less than 1 gram? It might weigh about the same as a dollar bill, which is 1 gram. If we put a paperclip and a dollar bill on a balance scale, they would balance, showing they weigh the same.
What about a sock? Is it heavier or lighter than 1 kilogram? A sock is lighter than a pineapple, which weighs 1 kilogram. On a balance scale, the sock would be higher than the pineapple, showing it weighs less.
Capacity tells us how much something can hold inside. We measure capacity with cups, pints, and quarts. A cup is like a small measuring cup used in cooking. A pint is like a bottle of juice, and 1 pint equals 2 cups. A quart is like a milk carton, and 1 quart equals 2 pints or 4 cups.
We can guess how much a container can hold by thinking about these measurements. Let’s try it! Look at a soup ladle. Do you think it holds more or less than 1 cup? Since the ladle is smaller than a cup, it holds less than 1 cup.
Now, think about a fishbowl. Is it more or less than 1 pint? A fishbowl is bigger than a juice bottle, so it holds more than 1 pint.
Finally, look at a jug. Do you think it holds more or less than 1 quart? Since the jug is bigger than a milk carton, it holds more than 1 quart.
Did you know that if you fill a 1-liter bottle with water, it weighs about 1 kilogram? That’s because 1 liter of water is the same as 1 kilogram!
Weight Guessing Game: Gather a few household items like an apple, a toy car, and a book. Ask the children to guess which item is the heaviest and which is the lightest. Then, use a kitchen scale to weigh each item and see if their guesses were correct. Discuss why some items are heavier or lighter than they appear.
Capacity Challenge: Provide children with different containers such as a cup, a small bowl, and a large jar. Fill a measuring cup with water and ask them to estimate how many cups of water each container can hold. Let them pour the water into each container to check their estimates. Encourage them to think about why some containers hold more than others.
Observation Walk: Take a walk around the house or classroom and identify objects that are measured by weight or capacity. For example, a bag of flour (weight) or a bottle of juice (capacity). Ask the children to think about why it’s important to know the weight or capacity of these items in everyday life.

**Weight and Capacity**
Weight measures how heavy or light something is. We measure the weight of objects by placing them on a scale. Weight is measured in pounds (lb) or kilograms (kg). For example, a loaf of bread is about 1 pound, a dollar bill weighs about 1 gram, and a pineapple weighs about 1 kilogram. There are 1,000 grams in 1 kilogram, and 1 kilogram equals about 2 pounds.
We can estimate how much something weighs and check our estimates by using a balance scale. For instance, let’s estimate the weight of a dog. Is it more or less than one pound? Think about whether a dog weighs more than a loaf of bread or less. I estimate that a dog weighs more than a loaf of bread, so the dog weighs more than one pound.
Using a balance scale, we can see that the dog weighs more than one pound since it is lower on the scale compared to the loaf of bread.
Now, let’s estimate the weight of a paperclip. Is it more or less than 1 gram? Could it be about the same weight as a dollar bill? I estimate that a paperclip weighs about the same as a dollar bill, or 1 gram. The balance scale shows that the paperclip weighs 1 gram, and since the scale is even, both the dollar bill and the paperclip weigh the same.
Next, let’s estimate the weight of a sock. Is it more or less than 1 kilogram? Is a sock heavier than a pineapple? I estimate that the sock weighs less than a pineapple, or less than 1 kilogram. The balance scale confirms that the sock weighs less than 1 kilogram, as it is higher than the pineapple on the scale.
**Capacity**
Capacity measures how much something can hold. We measure capacity with cups, pints, and quarts. A cup is a measuring cup used in cooking. A pint is similar to a bottle of juice or soda from a vending machine, where 1 pint equals 2 cups. A quart is like a milk carton, where 1 quart equals 2 pints and 1 quart equals 4 cups.
We can estimate the capacity of containers by thinking about these types of measurements. For example, let’s look at a soup ladle. I estimate that the soup ladle is less than one cup. We can use a measuring cup to check our estimate, and since the cup is bigger than the ladle, the ladle is indeed less than one cup.
Now, let’s estimate the capacity of a fishbowl. Do you think it is more or less than one pint? I estimate that the fishbowl is more than one pint. We can use a juice bottle to check our estimate, and since the bottle is smaller than the fishbowl, the fishbowl is more than one pint.
Finally, here is a jug. Estimate the capacity. Do you think it is more or less than one quart? I estimate that the jug is more than one quart. We can use a milk carton to check our estimate, and since the carton is smaller than the jug, the jug is indeed more than one quart.
