Engineering & Design Process
A problem is identified in this step of the Engineering and Design Process
What is ask?
We use variables to write this predictive statement.
What is a hypothesis?
In a hypothesis, we state what we think will happen in the experiment. It is also known as a ________________.
What is a prediction/educated guess?
Laboratory tools are used to sharpen our five sense and take measurements. They also help us gather this important evidence for experiments.
What is data?
In this step, you are working to make your design better.
What is improve?
This variable is changed by the scientist; it's the action.
What is the independent variable?
These two things help us write a clear hypothesis.
What are variables?
This tool is used to see very small objects that cannot be seen with the eye alone.
What is a microscope?
In this step, you are testing your plan out to see how it works.
What is create?
This variable shows what is being measured; it's also your prediction.
What is the dependent variable?
Use the variables to state the hypothesis.
Independent Variable: Read small print
Dependent Variable: cause a headache
If I read small print, then I will get a headache.
Thermometer's measure _____________________ in degrees Fahrenheit, or Celsius.
What is temperature?
In this step, you are drawing a diagram; or you are creating a step-by-step procedure.
Read this hypothesis and identify the independent variable.
If I increase the amount of time I spend in the sun, then I will get a sunburn.
Increase the amount of time in the sun
Use the variables to state the hypothesis.
Independent Variable: increase the amount of time studying
Dependent Variable: increase test scores
If I increase the amount of time I study, then my test scores will increase.
This tool measures mass in units called grams.
What is a triple beam balance?
This is the "hypothesis" stage; or when you're coming up with ideas.
What is brainstorm?
Read this hypothesis and identify the dependent variable.
If I increase the amount of time I spend in the sun, then I will get a sunburn.
I will get a sunburn
How can a science student make a good prediction about what will happen in an investigation that has not been done yet?
a)There is no good way to make a good prediction.
b)She can think about what she wants to happen next.
c)She can look at what happened in the past.
d)She can make a wild guess.
What is c?
She can look at what happened in the past.
This tool measures force in units called Newtons; it also measures weight.
What is a spring scale?
