Question 2

MAKE YOUR OWN KEY TO IDENTIFY FRUITS


Plants and animals are useful to humankind. We need plants for food and medicine, to supply the

atmosphere with oxygen, to help water conservation, etc. It is important to identify the plants to

know its’ usefulness. One way to identify plants or animals is using keys. One of example is the

following keys that can be used to identify nuts and beans. You may try to use the keys.


Objectives:

In this experiment you will identify some fruits based on a key you made using known beans and

nuts.


Materials:


1\. Small bags


2\. Various kinds of beans

a. Red beans

b. soy beans,

c. coffee beans

d. cashew nuts

e. peanuts


3\. Baby carrot (15 kg)


4\. Passion fruit (15 kg)


5\. Zalacca (10 kg)


6\. Mangosteen (10 kg)


7\. Baby radish (15 kg)


8\. Radish (5 kg)


Procedure:

Creating your own keys

Observe five different beans and nuts available on your desk, use the following keys and put the

beans on little plastic bags available inside a red color code bag.


Use the following keys to identify the object



1\. Is the beans smells coffee? If yes ………………..Coffee bean

If not …………………………………………….. go to no 2



2\. Is the beans has black spot ? ……………………. Soy bean

If not …………………………………………….. go to no 3



3\. Is the beans has red color? …………………….. Red bean

If not …………………………………………….. go to no 4



4\. Is the beans longer than 4 cm ……………… Cashew nut

If not ……………………………………………. Peanut


Questions:


1\. Keys are made based on a range of biological character such as shape, color etc. Create

keys as many as you can to identify the following objects available on the bucket.


2\. With your ruler measure the dimension of those objects and plot your measurement in the

following graph. Use the axis of each object to measure the length and width see the example


3\. Keys are made based on a range of biological character such as shape, color etc. Create

keys as many as you can to identify the following objects available on the bucket. Remember

each item (number) maximum contain only two statements.


4\. With your ruler measure the dimension of those objects and plot your measurement in the

following graph. Use the axis of each object to measure the length and width see the example
