Twig Science Module 1 Vocab Quiz

Material

• Scientists use different methods of observation while

  investigating materials. These methods help them to identify

  materials without changing them in any way.

• All objects are made of some kind of material, or a combination of

  materials. There are lots of different types of materials. Animals and

  plants are made up of living materials.

• a material that water cannot soak into

  My new raincoat is 100% waterproof; it keeps my clothes completely dry!

• The characteristics of a material are its properties. Some can be

  observed; others can be discovered through testing.

Methods of

Observation

• Scientists use different methods of observation while

  investigating materials. These methods help them to identify

  materials without changing them in any way.

• Changing only one thing (variable) at a time in an experiment keeps

  it fair and gives accurate results.

• The characteristics of a material are its properties. Some can be

  observed; others can be discovered through testing.

• An item or condition that can be changed or controlled (kept the

  same) in an investigation.

Property

• An item or condition that can be changed or controlled (kept the

  same) in an investigation.

• A combination or two or more substances (or materials).

• The characteristics of a material are its properties. Some can be

  observed; others can be discovered through testing.

• When two or more substances are combined and a NEW

  substance is produced with new and different physical and

  chemical properties.

Opaque

• how a material feels (rough or smooth)

  The rocks at the beach hurt my feet while the texture of the sand is much softer.

• does it attract or repel a magnet?

  All magnetic materials are metal but NOT all metals are magnetic.

• not transparent (you can’t see through something that is opaque)

  The blackout curtain is opaque so light cannot travel through it.

• can electricity travel through it?

  Electrical conductivity is tested through a closed-loop circuit.

Waterproof

• not transparent (you can’t see through something that is opaque)

  The blackout curtain is opaque so light cannot travel through it.

• can heat travel through it?

  Material that conducts thermal (heat) energy would not make a good potholder!

• how a material feels (rough or smooth)

  The rocks at the beach hurt my feet while the texture of the sand is much softer.

• a material that water cannot soak into

  My new raincoat is 100% waterproof; it keeps my clothes completely dry!
