MTTC Integrated Science
WITH COMPLETE SOLUTIONS
- should not be altered, erased, or whited-out to make corrections
Observational recordings
- drawing a single line through it
1. title
2. abstract
- contain the hypothesis
- include a control and one variable
Parts of a lab report
3. introduction
4. methods
5. results
6. conclusion / summation
Volumetric flask - used to accurately prepare a specific volume and concentration of solution
used for mixing, transporting, and reacting
Erlenmeyer flasks
NOT appropriate for measuring
Meniscus where the liquid measurement is read
- precise measurements
Graduated cylinders
- more accurate than Erlenmeyer flasks or beakers
- glassware to accurately dispense liquid
Burette
- has a stopcock and a tip
- typical = 1 lens
Typical vs. Compound microscope
- compound = 3 lenses
Chromatography set of laboratory techniques used to separate or analyze mixtures
Diluting Acids - always add the concentrated acid solution to water
- used to separate the components of a heterogeneous mixture by spinning it
ex. separate blood cells and plasma
Centrifuge - the heavier cells settle on the bottom of the test tube and the lighter plasma stays
on top
ex. salad spinner to dry lettuce

Calorimetry used to determine the heat released or absorbed in a chemical reaction
Titration helps determine the precise endpoint of a reaction
- meter: length
Metric system - liter = volume
- gram = mass
*independent variable = what is being manipulated is on the x-axis
Graphs of independent vs dependent
variable *dependent variable = the ones that may change as the independent variable
changes is on the y-axis
1. understand scientific concepts
2. appreciate "how we know" what we know in science
3. understand the nature of science
5 skills developed from the National
4. Develop the skills necessary to become independent inquirers about the natural
Science Education Standards
world
5. develop the skills necessary to use the skills, abilities, and attitudes associated with
science
Scientific fact an objective and verifiable observation
greater body of accepted knowledge, principles, or relationships that might explain
Scientific theory
why something happens
Hypothesis - an educated guess that is not yet proven
Law an explanation of events that always leads to the same outcome.
1. identify a problem or posing a question
2. formulating a hypothesis or an educated guess
3. conducting experiments or tests that will provide a basis to solve the problem or
Scientific Method
answer the question
4. observing the results of the test
5. drawing conclusions
1. able to ask questions about objects, organisms, and events in the environment
2. devise a simple investigation to answer a question
3. use tools such as magnifying glasses, rulers, and balances to gather data and
make observations
6 abilities of K - 4 Students
4. use the gathered data and observations to provide an explanation
5. talk about, draw pictures, or use another method to communicate the results of an
investigation and what they learned
6. understand the scientific inquiry
