| What is life science? | the study of living things
🗑
|
||||
| Describe the scientific method. List the steps involved. | Scientific methods are how scientists solve problems. Steps of the scientific method include ask a question, make an observation, form a hypothesis, test the hypothesis, analyze the results, draw conclusions, communicate results
🗑
|
||||
| What is a hypothesis? | an educated guess
🗑
|
||||
| How do you test a hypothesis? | by using a controlled experiment
🗑
|
||||
| What do you do if the hypothesis is correct or incorrect? | If correct, repeat the experiment to see if you get the same results, and if incorrect, either adjust your hypothesis or redo the experiment.
🗑
|
||||
| Explain what variables are involved in a scientific method. a. experimental variable. b. controlled variable | experimental variable - variable that is being tested
controlled variable - variable that stays the same in an experiment

| Why is the metric system (SI) of measurement an important tool in science? | Because scientists around the world use the same measurements so it is easy to share results of experiments

| Microscope parts: ocular lens (eye piece) | what you look through - it magnifies
🗑
|
||||
| objective lens | magnifying glasses/makes objects look closer/bigger the lens=more magnification
🗑
|
||||
| diaphragm | also known as light condenser - controls the amount of light coming through the stage
🗑
|
||||
| stage | place to put slide/specimen
🗑
|
||||
| stage clip | holds slide in place
🗑
|
||||
| nose piece | holds the objective lenses
🗑
|
||||
| course adjustment knob | lets you adjust the stage or magnification/this is largest change in magnification/you can see movement
🗑
|
||||
| fine adjustment knob | final focus/makes what you are viewing look as clear as possible/little movement
🗑
|
||||
| Explain the differences between a compound light microscope and electron microscope | compound - uses light to view objects that can be living; electron - focuses a beam of electrons to magnify objects - cannot view living things
🗑

| Characteristics of living things cells | all living have to have cells-basic level of life
🗑
|
||||
| responds to change | stimulus - change that affects the activity of an organism-reacting
homeostasis - maintaining a stable internal environment-balance
🗑
|
||||
| reproduction | sexual - 2 parents
asexual - 1 parent
🗑
|
||||
| DNA - heredity | all living things contain DNA in their cells
🗑
|
||||
| energy-metabolism | total of all the chemical activities that the organism performs
🗑

🗑
|
||||
| a place to live | need shelter from the elements
🗑
|
||||
| food | need nourishment to keep cells developing
producers - make their own food
consumers - eat other plants/animals
decomposers - break down nutrients in dead organisms
🗑

| proteins - amino acids | needed to build and repair body structures
🗑
|
||||
| carbohydrates | source of energy and energy storage
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
