Equipment (To join entirely optional practicals)
It is a good idea to have a whiteboard or paper, pen, ruler and calculator to hand in each session.
To extract DNA:
- Small jug or beaker
- a fork
- 1/4 of a banana (a similar volume of kiwi or defrosted peas or a couple of strawberries should also work)
- A teaspoon of table salt
- A teaspoon of liquid soap / washing up liquid
- About 50mL very warm water (approx. 60℃) Take care against scalding and with water near electronics. Supervision with younger children is strongly recommended)
- A thermometer is helpful but not essential
- Filter paper: a coffee filter paper is fine (+ spare if possible), a muslin cloth would also work, but might be more difficult to handle.
- approx. 10mL very COLD isopropyl alcohol / surgical spirit / rubbing alcohol (available at most pharmacies and supermarkets) This should be placed in the freezer for at least an hour before use and only taken out when needed towards the end of the session.
- Tall, narrow glass or 50mL measuring cylinder
- A Pipette is helpful but not essential
- Long skewer / slim stick / pipe cleaner
To make a personalised hanging DNA model mobile:
- Two long pipe cleaners (ideally 30cm, but shorter would also work)
- Beads: four colours, at least three of each colour
- Scissors (take care with sharps)
- Dark felt pen or marker (fine tip)
- Four paper straws cut into pieces about 2cm long
- Colour pens / pencils (optional)
- eight pipe cleaner pieces, each cut to approx. 6cm.
