Sadie decides to do an experiment on her dog to see if adding eggs to his diet changes his appearance. In her initial observations, she describes the dog as overweight, furry, and tall. What is wrong with her description?
It sucks! What does tall even mean? Can't she use a ruler?
The amount of matter something has, how much space it takes up
A 7kg bowling ball is pushed down a lane. This causes the ball to accelerate at a rate of 10 m/s. What is the force on the ball?
70N
What is oxygen?
An element! (made of only one type of atom)
You are doing a test to see how much sunlight affect's tomato plants growth. What are three constant or control variables?
Temperature of room, pH of soil, amount of water, time of water, amount of fertilizer, height and width of plants to start.
In the USA, it has been found that people with more than 5 TVs have better dental hygiene. What is the connection here?
What is the term for pushing or pulling on something?
Force
Ms. Cunningam's dog, Dakota, has a mass of 80kg. What does she weigh on the moon (where the gravitational force is 2m/s2)?
160N
What is salt (sodium chloride)
A compound (made of 2 or more different types of atoms)
Jonny did a scientific experiment one day and discovered during his trial that when he plays video games for more than an hour, he actually gets more energy. What is the biggest flaw with this experiment?
Number of subjects, number of trials!
A group of rats is given skittles every day to see if skittles make them hyper. What would be a control group?
A group of rats that gets NO skittles.
How does the magnitude of a force relate to the movement of an object?
Generally, the greater the force, the greater the movement or impact on the object.
Fill in the blank: Newton's First Law means that all of the forces on an object are:
Balanced
What is freshly squeezed orange juice?
A pure substance (even though it has TONS of different atoms, elements, and compounds in it)
Put these following steps in order for the scientific method:
Observations, Data Analysis, Hypothesis, Materials and Procedure, Conclusion
Hypothesis, Materials and Procedure, Observations, Data Analysis, Conclusion
Why does a science report with the scientific method need to be SO detailed?
So someone can repeat your experiment EXACTLY the way you did it.
Why does Mr. Pilling weigh less on the moon than he does on the Earth?
Buoyancy
What type of mixture is a caesar salad?
Heterogeneous Mixture (hetero meaning DIFFERENT)
A group of chickens is given Omega-3 in their diet and then injected with the avian flu virus to see if the Omega-3 had any impact on the course of their disease. What would be a good measurable dependant variable for this experiment?
If the chickens live or die, or how sick they get.
Ms. Cunningham observes that the birds in the park have become smaller in the last few years, likely due to climate change and wants to publish her findings in a new book. What is wrong about her conclusions?
For every ghost pepper hot wing I eat, my stomach churns and burns more and more. This is a loose example of what physics law?
Newton's Third Law-for every for force, there is an equal opposite force.
What kind of force are magnets?
Action-at-a-distance force
