Changes are happening all around us. We observe change as we watch trees lose their leaves, smell bread cooking, feel a footpath become slippery with the rain or watch the sun set slowly over the horizon. We cause changes to the shapes of things around us as we wring a towel out to dry, stretch a watchband to fit our wrist, bend a straw towards our mouth to drink or scrunch up a piece of paper before throwing it away.
The Bend it! Stretch it! unit is an ideal way to link science with literacy in the classroom. It provides opportunities for students to explore how we use twisting, stretching and bending to physically change the shape of everyday materials. Through hands-on activities, students investigate the effect of heat on the ability to shape playdough.
