How much tea can actually fit in a tea cup? To find out your child will need a measuring cup and some household objects. This worksheet is all about determining the volume of an object. To complete this activity your child will need to look at the objects pictured, estimate how much liquid they can hold, and then measure the volume and write the findings on the page. How close were his estimates? This worksheet will support the important scientific principle of making a hypothesis and then testing it through experimentation.
