Look at this drinking straw in my hands. What do you think will happen if I gently bend it?
Now look at this wooden ruler. What do you think will happen if I gently try to bend that one?
Today's words: bendy — it curves when we gently push it. stiff — it stays straight and does not bend easily.
Look at our tray. Which things do you think will bend? Which do you think will stay stiff?
At your tray, gently try to bend each thing with two hands. Does it curve, or does it stay straight? Take turns. Keep it away from faces.
Now sort your things at your group's hoops. Put the bendy ones in one hoop. Put the stiff ones in the other hoop. Tell a friend why each one goes there.
On your Investigation Journal page, show the bendy things and the stiff things. Draw or mark one bendy thing and one stiff thing. Point to which is which.
