Characteristics of Objects

This week's episodes and hands-on activity explore re-engineering.

Students will learn about the different types of fasteners to investigate which fastener is best for a particular material or job and why.

Students develop and apply comparing & contrasting, observing, and predicting as they investigate the properties of familiar objects and materials.

Will it slide or stick? Students conduct a fair test to investigate how different solid surfaces affect the movement of an object on a ramp.

Students identify and sort objects, including fasteners, according to material and purpose.

Students work collaboratively to design and build a floating device.

Students work collaboratively to design and build a boot tread that will use friction to prevent slipping on an incline.
