Scientific Procedure
What is the first step in the scientific procedure?
Observe- gather information on a topic of interest
What PPE should be worn at ALL times in the Lab?
Safety Glasses or safety goggles
Which of these should not be disposed of in the sink?
a. lemon juice
b. colored water
c. sand
d. baking soda dissolved in water
sand
the series of steps for scientists to follow in order to understand how things work, and why they work the way they do is known as the
Scientific Method
Type of data that tells us how many, how much or how often. This data uses numerical data.
Step in the scientific method that looks at the results and determines whether or not the experiment supported or contradicted the hypothesis
Conclusions
It is important to know the location of which items in the lab to ensure safety of everyone?
Fire Extinguisher, First aid kit, eye wash station, fire alarm, gas shut off switch
True or False: You can eat food in the lab if all tables are wiped down before hand
False
the variable in an experiment that is deliberately changed on purpose
Independent Variable
Type of data that helps us understand why, how or what happened. This data uses non numerical data
Qualitative
What step in the scientific method is the actual step where scientists design, carry out tests, or trials that will help determine if their hypothesis was supported or not
Experiment
True or False: If you spill something in the lab, it is okay to wait until the end of the hour
False
Which of the following is acceptable lab behavior?
a. leaning across the lab table
b. using a dustpan to clean broken glass
c. eating snacks in the lab
d. directly smelling a chemical mixture
using a dustpan to clean broken glass
The variable in an experiment that is the result of the changed variable.
Dependent Variable
Observations and data that is collected throughout the experiment is known as the
Results
What is the 3rd step in the scientific procedure
Form a hypothesis
What is the correct way to check to odor of a substance in the lab?
Use your hands to wave / waft the scent towards your nose.
Students with long hair and jewelry should do what in the lab?
Students should pull their hair back and take off any jewelry before entering the lab.
Which variable always stays the same in an experiment and why?
Control- something needs to stay constant so that the only way the dependent variable is changed is directly a result from the independent variable
What is step 2 of the scientific method after observing / gathering information
Identify a problem or reason to support the experiment and hypothesis
After forming a hypothesis and before starting the experiment you need to do what to ensure you have all of your items for the experiment?
This is also step 4 of the Procedure
Gather Materials
What is the number 1 priority in the science lab?
Safety
What is one example of a time a student may need to use the eyewash station?
Chemical in the eyes
other answers may be accepted
Why is it important to follow the steps in the correct order for the scientific procedure?
This ensures all steps are being taken in the correct order and nothing is forgotten. There are also safety features that may have to be done in a certain order.
Other answers are accepted as well
What is the most important thing to remember when completing a lab in the science lab, shop or classroom?
Safety
