Midterm Review
1. Graphing
• Reading graphs--correctly read a specific value --compare two different values within the same graph
• Identify trends
• Find areas of increase and decrease--sharp or gradual increase and decrease
• Read values from a scatter plot
•Match table to graph
Which graph matches this table of data?
Food items Fat (in grams)
Raw clams 2
Fish sticks 10
Canned tuna 6
Lean ground beef 8
Lamb chop 4
Canned Ham 2
•Select one or more points from a table
Make a graph• Multiple bar graph• Multiple line graph• Scatter plot
For all three:--Informative title--Labeled axes--evenly spaced--Graph uses as close to full space as possible--Includes key if necessary--points correctly plotted--correctly drawn best fit line if applicable
2. What is and is not science• Science is the search for answers about the
natural world and how it works.
It is not “the truth”—science is always changing based on new information.So we don’t say we have proved a hypothesis: our hypothesis is supported.It is not simply experimentation.It cannot answer every question.
3. Observation and Inference
• Observations: what you perceive with your senses
• Inferences: conclusions drawn from observation and background knowledge
4. Variables: Independent, dependent, controlled• Identify independent and dependent
variables:--by definition--in a table--in a graph--in a purpose question--in a description of an experiment
Controlled variables
• Definition• Identify in an experiment• List controls based on understanding what
would make a comparison “fair”• Identify control group vs. experimental group• Identify what’s wrong with an experiment
5. Scientific Inquiry• Know steps of Scientific Method
• Know that the steps don’t have to be in a certain order: there is no fixed Scientific Method
• Know definition of hypothesis: --A tentative explanation for an observation, phenomenon, or scientific problem that can be tested --Must be falsifiable (can be proven false if it is false)
6. Cells
• Properties of living things• Cell Theory• Prokaryotic cells—types, role in Earth history
and present• Prokaryotic vs. eukaryotic cells
