Scientific Investigations
What is the definition of an independent variable?
A factor of an experiment that is changed intentionally
What is the formula to calculate volume?
L x W x H
What is the last step of the Engineering Design Process?

In Cornell Notes, where to you write down questions?
On the left 1/3 of the page
What metric unit best compares to the height of a flagpole? - mm, cc, m, km
M, or meters
What is the definition of data?
Information gathered by observations and experiments, used for analysis
What is the main formula for finding the density of an object?
M/V
What is a trade-off?
A trade-off is giving up one advantage to keep another
In Cornell Notes, what do you write for the summary?
The summary addresses the EQ of the lesson and answers the questions
How do you find the diameter of a circle?
You measure the length across it
What comes after identifying an independent variable? (Scientific Method)
Collecting and organizing data
What is the difference between mass and weight?
Mass is the amount of matter in an object, and weight is a measure of gravitational force
Why are trade-offs useful?
Trade-offs are useful because they allow you to keep one advantage and give up another, and the kept advantage might really help
In Cornell Notes (revisions) , what does an asterisk mean?
An asterisk means to identify information that is used in a test, essay, exam, etc...

1050 grams
How can you tell between a reliable source of information and a non-reliable source?

Reviewing your notes
What is the volume of a pyramid whose length is 6 cm, width is 5 cm, and height is 5 cm? Hint - The formula is length times width times height divided by 3
50 cc
Why are hypothesis always testable?
If they are not testable, they cannot be proven
What is density?
Density is the measure of the amount of mass in a given volume
Why do you build a prototype?
You build a prototype to test an idea with a small model, because it is safer and will tell you if that idea works
In Cornell Notes (revisions) , why does it help to highlight main ideas?
Challenge: How does this connect to the real world?
It helps to highlight main ideas so when you are taking a test, you can find the highlighted word(s) easily
This connects to the real world because everyday, people highlight main ideas to help with organization
ex. Take a look at your science textbook
Do the highlighted words stand out? Is it more organized and easier to read?
