Energy and Change

 

2.1 Students demonstrate different ways that forces (including push and pull) change the shape and motion of objects.

2.2   Students identify and describe forms of energy in their community (including heat and energy of movement).

Different ways forces can be used to change shape and motion of objects:

·        dropping, throwing

·        pushing, pulling

·        squeezing, stretching, twisting

·        colliding

·        propelling

Factors which can affect motion and shape of objects:

·        size, shape

·        texture

·        mass — heavy, light

·        different surfaces

·        size of force

Exploration of students’ own concepts of different energy forms — electricity, light, heat, movement, sound:

·        different ways of making a golf ball or balloon move

·        produce and describe different types of sound and different coloured light

·        sources of heat in the home

·        ways to control heating and cooling in the home

·        sources of heat — fuels, friction

·        items in the classroom that use electrical energy

·        sources of sound — doorbells, musical instruments, various objects in the school

·        animals use light to see

2.3 Students illustrate the ways that energy is used in their community.

 

Uses of energy in the community:

·        cars, trucks, boats, planes require fuel to move

·        electricity in shops, factories, dentists’ surgeries and for street lighting

·        sounds

·        heating in the home — oven, kettle

·        different ways people use solar energy — drying clothes, heating water in the home, growing plants
