Scientific Investigation
Tell me 2 lab safety rules
examples: never drink, taste, or smell anything during a lab, wash your hands, wear safety goggles, close toed shoes, report accidents to teacher, learn where safety equipment is and where emergency exits are
What are the difference between prokaryotic and eukaryotic cells?
prokaryotic are single cellular organisms- unicellular
eukaryotic are single or multi-cellular organisms and they have a nucleus
Motion occurs when a force is applied and an object changes position...True or false
True
Kinetic and potential
If the Southern Hemisphere receives more direct sunlight would it be winter or summer?
summer
What are the units of measurement for mass, area, and volume
grams, meters, and liters
Name 4 parts of a cell
What is the unit for force? (Hint named after a scientist)
Newton
False
What are some ways the Earth moves?
on an axis, rotating, revolutions, and orbiting
There are 7 parts of the scientific method- name 4
1. Problem, observations, hypothesis, experiment, collect data, interpret and analyze data, and conclusions
Chloroplast is only found in what type of cells
plant
Name at least 2 of the types of friction
Examples: static, sliding, rolling, fluid
Name 3 of the 5 types of energy
physical, chemical, mechanical, light, nuclear, gravitational potential energy
Does the Earth have a bigger gravitational pull on the moon than the moon has on Earth? Why?
Yes because Earth has more mass
What do the three types of variables mean- independent, dependent, and constant?
independent- something is changed
dependent- something is measured
constant- something staying the same
What are the 5 phases of Mitosis?
Interphase, prophase, metaphase, anaphase, telophase
What is the opposite force of gravity?
air resistance
What is a complex machine?
2 or more simple machines working together
Why do tides happen and how often do they occur?
They occur every 24 hours (12.5 hours for high tide and 12.5 hours for low tide) and they happen because of the gravitational pull on Earth
Give me an example of a lab we did this year using the scientific method
penny lab, ball drop,
What is the difference between mitosis and meiosis?
Mitosis creates copies of body cells to repair or regrow, meiosis produces gametes for sexual reproduction
How many Newton's laws are there and tell what one of them means.
3, example: an object at rest will stay at rest and an object in motion will stay in motion, force is the outcome of mass and acceleration, for every action there is an equal but opposite reaction
Name at least 4 of the 6 types of simple machines
inclined plane, wedge, screw, lever, wheel and axle, pulley
Name the phases of the moon starting from new moon
new moon, crescent, 1st quarter, waxing gibbous, full moon, waning gibbous, 3rd quarter, crescent, back to new moon
