At the top of a rollercoaster, there is a maximum of kinetic or potential energy?
Potential

Give an example of a multicellular organism
Any plant/ animal

What is classification?
Sorting or organising things into groups.
100
What is the independent variable in this experiment? yellow (not placed in water), red (salt water, left overnight), green (plain water, left overnight)
What the gummies are placed in (nothing, salt water, plain water)
100
Define kinetic energy
Moving energy
200
What is an energy transformation?
Where the energy turns into another type of energy
200
Is this a plant or animal cell?
Plant (onion)

Why do scientists use keys?
Scientists use keys because they:
• are easier to use than detailed descriptions of each group
• show at a glance what distinguishing characteristics each group has
• make it easier to identify objects that have never been seen before
• always give consistent answers, regardless of who is using them

What is the dependent variable of this experiment? yellow (not placed in water), red (salt water, left overnight), green (plain water, left overnight)
The size of the gummy
200
Define potential energy
Stored energy (e.g. elastic, chemical, food, raising object to a height)
300
Give an example of kinetic energy
Anything moving

Name three organelles that are only in plant cells
Cell wall (structure of cell), chloroplasts (photosynthesis), large vacuole (water storage)

What is a dichotomous key?
The most common type of branching key is a dichotomous key. Dichotomous keys have two choices at every branch. They start at the top with one large group and slowly subdivide into smaller and smaller groups until no more choices are possible.
300
What are 3 controlled variables?
yellow (not placed in water), red (salt water, left overnight), green (plain water, left overnight)
1. the size of the gummy
2. the amount of water it is placed in
3. the size of the container they are soaked in
300
Define organelles and give 3 examples
A small structure in a cell that is surrounded by a membrane and has a specific function. e.g. nucleus, mitochondria, cytoplasm, chloroplast, cell membrane, cell wall
400
What is energy conservation?
Energy can never be created or destroyed. It can be changed only from one form to another.
400
What is the job of the
1. Mitochondria
2. Nucleus
3. Cell membrane
1. Mitochondria- energy created from cellular respiration
2. Nucleus- contains DNA, controls cell
3. Cell membrane- controls what enters and leaves the cell
400
What is a tabular key?
Like branching keys, the idea is to start at the top and work your way down. Tabular keys can also be dichotomous, having two choices at each level in the key.
400
What is the independent variable?
Time
400
Define dichotomous key
Dichotomous keys have two choices at every branch.

What are the three parts to the cell theory?
1. All living organisms are composed of one or more cells.
2. The cell is the basic unit of structure and organization in organisms.
3. Cells arise from pre-existing cells.

What are the features of this graph?
1. Title
2. Even scale
3. Labelled x- and y- axis, with units
4. Points plotted5. Line of best fit

What is classification?
Classification is the organisation of different things into groups of related types.The process that sorts all living things into groups is called taxonomy.
