Hypotheses
How many parts are there in a hypothesis?
2, the what and the why
What does abiotic mean?
NOT living things, for example rocks
What does LOBF stand for?
line of best fit
What is the mnemonic that helps you remember the correct order of the metric units?
King Henry Died By Drinking Chocolate Milk..Maybe..Not
What part of a trophic level pyramid is the producer?
the bottom
What is it called when we can test something multiple times?
Repeatability/repetition
What does biotic mean?
Living or ONCE living
What is interpolation?
the part of the LOBF for which we DO NOT HAVE data
What does DRUL mean?
down, right
up, left
What are the 2 types of competition?
Intraspecific- within the same species
Interspecific- between 2 or more species
Name the 4 parts needed for a good hypothesis
Variables, Quantity, Testability, Justification
A student in your classroom wants to know if his toy dinosaur plushie is biotic or abiotic. What do you tell them?
Experimental set up with the absence of a variable, serves a reference against which change can be measured.
What is the standard unit of measurement for distance?
meter
How does the 10% rule relate to trophic levels?
10% of the energy from one level can be passed to the next level
Missing a good justification
Let's take a look in Claire's backpack: she has a notebook, a couple of pens, a wooden keychain, and a can of yogurt for lunch. Is each item biotic or abiotic?
All abiotic
What is a scientific law?
A hypothesis supported by repeated testing that consistently predicts what will happen
What is the standard unit of measurement for mass?
gram
Food chains follow a single path, food webs can have multiple paths
One requirement of a hypothesis has two parts. Which requirement is this and what are the 2 parts?
Testability. Is it testable? Is it testable multiple times?
If a trophic pyramid has 3 levels, and the mossy/leafy level has 1000 units of energy, how many units of energy are on the other levels?
Second level- 100 units
Third/top level- 10 units
What are the 5 elements of a high quality experimental design?
You have 4.56cl of water in your ecosystem tank, how many liters of water do you have?
0.0456 liters
Who receives a greater energy transfer PERCENTAGE? Primary consumer or a secondary consumer? Why?
They receive the same percentage because of the 10% rule. They would technically receive different amounts, however.
