<strong>Primary</strong> <strong>Science</strong> & <strong>Technology</strong> Teacher Manual – Resources – K – 4<br />
The groups will compare <strong>and</strong> discuss their findings.<br />
Teacher can challenge students to use identical sheets of paper to investigate<br />
what happens when different variables are changed e.g. the shape of the<br />
paper, the height from which the paper is dropped, the mass of the paper<br />
etc.<br />
Students can then compete to design from identical size of newspaper<br />
sheets, the slowest falling object/ the fastest falling object, etc.<br />
Teacher asks students to think of everyday occurrences where objects are<br />
designed to increase or decrease air resistance. For example, parachutes are<br />
slowed down by air resistance, racing cyclists wear a special type of helmet<br />
to reduce air resistance.<br />
ASSESSMENT<br />
Sample questions:<br />
1. What is the atmosphere made of?<br />
2. What do we call the pressure caused by air around us?<br />
3. Summarise the effect of air on a falling object.<br />
Sample answers:<br />
1. The atmosphere is made of a mixture of gases.<br />
2. The pressure caused by the air around us is called atmospheric<br />
pressure.<br />
3. Air slows down the motion of falling objects.<br />
