| Question | Answer |
|---|---|
| Define science | the study of a way to solve problems |
| The International System of Measurement (SI) is the | measurement system |
| What is the base unit for distance? | meter |
| What is the base unit for liquid volume? | liter |
| What is the base unit for mass? | gram |
| What is the metric unit for temperature? | Celsius |
| What is the abbreviation for meter? | m |
| What is the abbreviation for liter? | l |
| What is the abbreviation for gram? | g |
| What is the abbreviation for Celsius? | C |
| What are the 3 steps for using a formula? | Write the formula.Substitute the measurements with labelsAnswer with labels |
| Definition of perimeter | Distance around an object |
| Formula for perimeter | P= S + S+ S+ ... (s=sides) |
| Possible labels for perimeter | cm, m, mm, ... |
| A rectangle has one side that measures 4 cm and another side that measures 2 cm. Figure out the perimeter. | 4 + 4 + 2 + 2= 12 cm |
| Define area | measure of flat surface 2 dimensions |
| How do you calculate the area of a regular quadrilateral? | l x w or b x h |
| What is the label for area? | cm2 or mm2 or m2.. |
| Find the area for a rectangle that measures 4 cm by 2 cm. | 4 x 2 = 8 cm2 |
| Define volume of a solid object. | amount of space inside an object |
| Formula for volume of a solid object. | l x w x h |
| Label for the volume of a solid object. | cm3 |
| How is liquid volume measured? | with a graduated cylinder |
| What label do you use for liquid volume? | ml or cc |
| What are the rules for measuring with a graduated cylinder? | Measure on a flat surface. Measure at eye level. Read the bottom of the meniscus |
| What is the meniscus? | curve formed by the water adhering to the sides of the graduated cylinder |
| What is the graduation on a cylinder? | the little lines |
| Graduated cylinders are named by | how much it can measure- 10 ml, 100 ml, 250 ml |
| What is the method used to find the volume of an irregular object? | liquid/fluid displacement |
| List the five steps of fluid displacement | 1. Fill the graduated cylinder with water to cover the object2. Record the starting volume3. Gently insert object4. Record ending volume5. Subtract ending volume minus starting volume |
| What is mass? | the amount of matter in an object |
| How is mass measured? | with a triple beam balance |
| What are the four rules for using a triple beam balance? | 1. Carry with both hands2. Return all riders to zero before removing object3. Do not put chemicals or liquids directly on the pan.4. Calibrate |
| What does it mean when the triple beam balance is calibrated? | all of the riders are at zero and the pointer points to zero |
| What do you do if the triple beam balance is not calibrated? | turn the zero knob |
| To find the mass of a liquid, subtract _____ from _____ | mass of the container with liquid from the mass of the container= mass of the liquid |
| The mass of the container is the ____ | tare |
| Define weight | the pull of gravity on mass |
| Weight is measured with | spring scale |
| Label for weight | Newtons |
| Temperature | the amount of heat energy |
| What is the temperature at which water freezes _____ degrees C? | 0 degrees |
| What is the temperature at which water boils _____ degrees C? | 100 degrees |
| What is body temperature _____ degrees C? | 37 degrees |
