Teaching methods and activities
For many students science has no real meaning if material is covered
by the read and discuss method. A hands--on approach is a wonderful way
to teach a concept.
1. Demonstration ? show your students a one?half piece of each of the
fruits. Help them observe and identify the placement of the seeds in each
piece of fruit. Then have students group the fruits according to how the
seeds are enclosed. You may wish to introduce the words berry, drupe,
and pome to your students. If so, explain that many fruits commonly called
berries are not berries according to the scientific definition.
II. Exploration ? give each group three pieces of fruit (one berry, one
drupe, and one pome), a plastic knife, and a piece of plastic. It may
be helpful to precut the fruit for your students. Have students cut their
fruit apart on the plastic, count the number of seeds in each piece, and
record their observations on a worksheet.
Tying
it all together There are many fruits found in farms and in
the wild in many African countries. Some of these fruits are sold in markets
and by the way side. Using the above classification into berries, drupes,
and pomes, the fruits in Africa can also be classified. The teacher should
find out if other forms of classification are used to classify fruits
in their country.
Assessment
The teacher should encourage the children to come up with their own classification
of fruits presented to them. The point to be emphasized is that there
should be consistency in the approach.
