The learning aim for your child this week is to use everyday language to talk about weight and be able to order objects from the lightest to the heaviest. To introduce the concept, you can simply practice comparing weights by holding different objects in your hands.

 

Here is a great discussion to have with your child:

How does an object's size affect its weight? Does bigger always mean heavier?

 Collect several objects, some that are big in size but light in weight and some that are small in size but heavy in weight, for example, a feather, a marble, a beach ball and a golf ball. First, you can ask your child Which ones are bigger? Both the feather and the beach ball are bigger. Then you can ask Which ones are heavier? The marble is heavier than the feather, even though the feather is bigger. And the beach ball is much lighter than golf ball, even though it is much bigger.

Why? Most kids will quickly realize that the beach ball is full of air, and air is very light. It's fun to hear what they think is inside of a golf ball (rock). After some discussion, they will understand that the more "stuff" (or matter) is inside of a given area, the more it will weigh. 

The above discussion will help your child understand that size and weight are not always related and that big objects can sometimes be light and that small objects can sometimes be heavy.

How many cubes/Lego blocks does it take to balance your object?

Today your child can use the weighing scale that they made yesterday to compare different objects like pencil, glue stick, small hair brush, spoon, small fruit or vegetable against number of blocks/cubes. This will help your child to find out how many blocks are needed to balance the object. The word ‘balance’ means both sides of the scale are the same weight. Watch the video below and have a go yourself with weighing various objects.

 

Key questions you can ask your child:

How many blocks do you think we will need to weigh the same as ……?

Is it lighter at the moment and why?

Is it heavier at the moment and why?

Write a list of number of cubes/blocks used for each object. Can your child find out which object is the heaviest by looking at the number of blocks used?

 Floating foil boat experiment: 

They will enjoy designing and making tin foil boats and testing how well these float. They can investigate how many gems in weight each boat can hold before it starts to sink, maybe even have a little competition!

 

For this activity you will need:

  • tin foil 
  • glass gems (alternatively you could use pennies or tiny stones)
  • water tray

Use various objects around the house that will fit into the weight balance to compare the weights. Ask your child to hold one item in each hand and estimate which is heavier and which is lighter. They can then use the balancing scales to identify which object is heavier and which object is lighter each time.

Which object is the lightest? Which object is the heaviest? which two objects are exactly the same in weight?
