Investigate the science of sticking and joining
FRIENDSHIP !
Did you enjoy doing the carbon conga and exploring chemical bonds with Harvey in this month ’ s Friendship ! issue of AQUILA magazine ? Perhaps it made you think about other types of sticky science . Let ’ s investigate !
HARVEY ’ S MISSION
There are lots of ways to join things together ; you can glue , nail , stitch , paperclip , tape , tie or fasten . But how do you know what method is BEST ? In this activity , we ’ re going to test them all out , tabulate the results and see which proves to be the most successful .

ACTIVITY SKILLS
1 HOUR +
STEP 1 : Use the various ways of joining two strips of paper / card as shown in the diagrams .
DIFFICULTY
STEP 2 :
Test each join with a gentle waggle and pull . Then try a harder waggle and pull . Score each of the joins out of ten , according to the following criteria . Make notes to show your findings .
• Did it really join ? ( Did it succeed ?)
• Does it waggle ? Much ?
• Does it separate easily ?
• Does it spoil the things you joined ?
STEP 3 :
Ask a friend to carry out similar tests . Compare your results . Which method proved to be the best ? Can you explain why you think this was ?
YOU WILL NEED o A responsible adult
