Combinations of different spices were used at variable concentrations in the preparation of various curry blends. The sample showed the highest sensory attributes in comparison with control curry sample was compounded with different spices, onion and garlic at variable concentrations in corresponding seasoning blend. The oleoresin of the seasoning blend that possessed the highest quality scores was prepared and subjected to freeze drying process after dispersion on suitable carrier. The flavour contribution percentages of the characteristic notes; light sweet top, medium aromatic, full boiled spicy and pungent spicy were calculated for each curry and seasoning blends. The hydro distilled (HD) oils of the selected curry and its constituents were subjected to GC-MS analysis. The results revealed the high contribution of the components possess spicy note in the raw curry sample. The components possess pungent notes showed less representation. β-Caryophellene was the major compounds in the HD oil of raw seasoning blends followed by δ-carene and arturmenone. The qualitative and quantitative variation in the volatile compounds separated from the HD oil of the freeze dried sample may be attributed to the interaction between such components and the used carrier (10% maltodextrin in water).

The research aimed at studying the effectiveness of Web Quests in learning science to develop the scholastic achievement and the skill of the environmental decision making for the preparatory stage pupils.

The study was applied to an intentional subject of (82) pupils, prep two. It was divided into an experimental group (40 pupils) and a control group (42 pupils). The researcher used the experimental method with two equivalent groups (experimental and control). The Web Quests were used with the experimental group, where the control group used the traditional technique of learning. The research tools, such as an achievement test, the measure of the environmental decision making, were applied. The results showed a statistically significant difference between the average score of the two groups on the post application in favour of the experimental group. This result confirms the effectiveness of Web Quests in developing the scholastic achievement and the skill of decision making.
