1991 Brownie Guide Badge Book - Science Investigator Badge
Keep a record of all your investigations and be ready to tell the tester all about them.
1) Carry out all these investigations:
a) Make some plain yoghurt. Divide it into separate containers and find out what happens if lemon juice or vinegar or bicarbonate of soda is added to one portion.
b) Grow a broad bean and find out what happens if it is left in the dark and then put in the light. If broad beans are not available you can use runner beans or garden peas instead.
c) Heat some egg white and explain how it changes.
d) Fill some bottles (or glasses) with water and play a tune.
e) Use a magnet and find out what happens when you put it near some iron, wood, paper and two other substances of your choice.
2) Choose and carry out two projects from the list:
a) make a device to measure time. Use your device to time a job. Tell the tester how accurate it was.
b) build an object that will transport a small load (such as a stock cube).
c) make an electric circuit that could be used as a torch.
d) build a tower and find out what load it would support.
3) Choose and carry out one of the following:
a) Visit a museum or exhibition that is of scientific interest. Tell the tester about your visit.
b) Find out about the discoveries of two famous scientists. Tell the tester about their work and how it has affected our lives.
