| Question | Answer |
| Life Science | Chapter 1 :SCIENTIFIC PROCESSES |
| PROCESS SKILLS | techniques and the ability to use our senses and acquired scientific knowledge to gain an understanding about scientific investigation. |
| OBSERVATION | an everyday process of noticing what is around us. |
| MEASURING | involves observing and taking measurable data by comparing the known units of measurement with unknown units . |
| ESTIMATING | involves the use of senses to observe and compare any object or observation with what has been previously observed or experienced. |
| PREDICTING | foretelling the likely result before an experiment is carried out. |
| INFERRING | the process of drawing conclusions based from observed data. |
| COMMUNICATING | process whereby we share information our findings. |
| DRAWINGS | drawings are used to communicate findings |
| MAGNIFICATION | extent or ratio at which the size of the actual object has been increased or reduced. |
| CALCULATION OF MAGNIFICATION | Magnification=size of image/drawing mm is divided by the actual size of specimen /object mm [the ratio magnification is always expressed with an x in front of the figure] |
| A MICROSCOPE | an instrument used to observe very small objects or organisms that are difficult to see when using our naked eyes. |
| THE EYE PIECE | the eye piece is the upper part of the microscope where one looks through to see the image of the object . |
| BODY TUBE | the body tube is a long tube holding the eye piece. |
| THE NOSE PIECE [TURRET] | the lower end of the body tube which holds three small tubes of varying lengths called objectives. [low magnification= x5] [medium magnification = x10] [high magnification= x40] |
| THE STAGE | the stage is widened platform where a glass slide with a specimen is placed. |
| ADJUSTMENT WHEELS [FOCUSING KNOBS] | two knobs that include the coarse adjustment knob and the fine adjustment knob |
| THE PRINCIPLES OF MAGNIFICATION OF A MICROSCOPE | eye piece lens x objective lens = total magnification |
