How many parts are there in a hypothesis?

2, the what and the why

100

What does abiotic mean?

NOT living things, for example rocks

100

What does LOBF stand for?

line of best fit

100

What is the mnemonic that helps you remember the correct order of the metric units?

King Henry Died By Drinking Chocolate Milk..Maybe..Not

100

What part of a trophic level pyramid is the producer?

the bottom

200

What is it called when we can test something multiple times?

Repeatability/repetition 

200

What does biotic mean?

Living or ONCE living

200

What is interpolation?

the part of the LOBF for which we DO NOT HAVE data

200

What does DRUL mean?

down, right

up, left

200

What are the 2 types of competition?

Intraspecific- within the same species

Interspecific- between 2 or more species

300

Name the 4 parts needed for a good hypothesis

Variables, Quantity, Testability, Justification

300

A student in your classroom wants to know if his toy dinosaur plushie is biotic or abiotic. What do you tell them?

It is abiotic
300
What is a control group?

Experimental set up with the absence of a variable, serves a reference against which change can be measured.

300

What is the standard unit of measurement for distance?

meter

300

How does the 10% rule relate to trophic levels?

10% of the energy from one level can be passed to the next level

400
Our hypothesis for plant growth is that the grass will grow 1 cm per week. We don't know how much the grass will actually grow, so we choose a random number that seemed reasonable.

Missing a good justification

400

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

400

What is a scientific law?

A hypothesis supported by repeated testing that consistently predicts what will happen

400

What is the standard unit of measurement for mass?

gram

400
What is the difference between a food web and a food chain?

Food chains follow a single path, food webs can have multiple paths

500

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?

500

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

500

What are the 5 elements of a high quality experimental design?

Testability, repeatability, control group, isolated variable, gradient
500

You have 4.56cl of water in your ecosystem tank, how many liters of water do you have?

0.0456 liters

500

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.
