STE 15100 Experiment Pack - The Vegetable Kingdom

 

INTRODUCTION TO THE PACK

This Experiment Pack comes with a comprehensive Instruction and Teaching Guide with numerous drawings and illustrations.

 

Each of the 33 experiments is clearly introduced, explained and accompanied by a series of student exercises in the form of Student Worksheets. With a clear progression these aid both the teacher and student to plan and carry out a clear programme of work covering essential parts of the GCSE syllabus and developing an understanding of the structure, growth, reproduction and behaviour of different types of vegetable organism.

 

An example experiment is given here. Fuller information on request.

EXAMPLE SECTION AND EXPERIMENT

 

 

7) ROOT VEGETABLES

 

The term “osmosis” has already been defined in the root section. Now you will be able to observe osmotic processes within a root vegetable: the potato.

 

EXPERIMENT 9

 

REQUIRED APPARATUS

3 test tubes

test tube rack

scalpel

ruler

1 potato

water

sugar

 

Step 1

Cut out 3 small cuboid shapes from the potato, size 50x5x3 mm, using ruler and scalpel.

 

Step 2

Fill the three test tubes with equal quantities of water and different quantities of sugar. Insert the potato pieces inside the test tubes and let them rest for 30 minutes.

 

Step 3

Extract the potatoes and measure their size:

 

A: mm………...x…………..x.……………..

B: mm………...x…………..x.……………..

C: mm………...x…………..x.……………..

 

EXERCISE

What conclusions have you reached about the sugar solutions inside the test tubes?

Did each have a sugar concentration that was smaller, equal or greater that that of the potato? Why?
