![]() The volume of a cone with height H and radius r, is exactly one third of the volume of the smallest cylinder that fits inside it. Volume of a Cone = ▁ x Area of circular base x Height Volume of a Cylinder = Area of circular base x Height You can use a “ What’s the big idea?” or “ Lab report/Science experiment” Kami template. Can the one hold 4 time as much as the other?Įxplain your discoveries about the volume of the cylinder and the cone.Can the one shape hold 3 times as much as the other?.Can the one shape hold twice as much as the other?.Explore how much coloured liquid each shape can hold.Now you have a cylinder and a cone shape with the same height and the same circular open top. If you didn’t do an extra flap, simply tape the sectors together into a cone shape, with cellotape or an extra piece of pealed contact. Peel off the paper and stick the sticky sides together. It can be helpful to cut a larger flap on one of the sectors. Place a piece of paper over your screen and trace the cone net sector shape.Ĭut out 2 sector shapes in plastic contact. Resize the cone net annotation (using the little purple circle in the bottom right of the annotation) to make the blue circle the same size as the circle shape of your glue stick lid. Your cone and your cylinder need to be the same height and have the same sized circle-shape at the top. a cone (we’ll make one using contact plastic). ![]() Using everyday materials, let’s make some connections to prior knowledge about a cylinder and see what we can learn about a cone. ![]()
