Semanoor Science Formula allows you to explore all about a three-variable formula. It deals with 24 of the most common three-variable formulae, in an interactive manner. Each formula is introduced with a brief overview about the lesson and presented in the form of a Workbench with 5 buttons:1-Proportionality: where you can drag slider(s) to study the proportionality and deduce the relations among variables, then confirm by answering a checkup question.2-Table: which summarizes the information about each term in the formula (Definition & unit).3-Calculator: which allows you to find the value of the unknown variable in the formula.4-Graph: which represents the relationship between any 2 variables in the formula.5-Evaluation: where you can review your knowledge by completing a set of exercises about the formula (including: match, multiple-choice & calculation questions). Some formulae include high order thinking question, where you have to analyze an illustrative figure to pick out the required information.The result is represented in the form of a report, which displays the correct answer, shows the number of attempt and allows you to repeat incorrect questions. *Some formulae are provided with a brief biography about the concerned scientist. 24 " " 1-: 2-: ( ).3- : .4- : .5-: ( ). . . .
