BIOLOGY
This part of a plant absorbs water and minerals and anchors the plant in the ground.
Root
This element has the symbol Fe on the periodic table.
Iron
This is how heat energy from the Sun reaches Earth.
Radiation
Heart rate is measured in this unit.
Beats per minute
This body system pumps blood around the body.
Circulatory system
This flat, green part of a plant is where most photosynthesis takes place.
Leaf
This is a pure substance made of only one type of atom.
Element
This type of heat transfer happens in solids when particles pass vibrations on to neighbouring particles.
Conduction
This type of graph is used when both axis contain numbers
Line Graph
Ice melting is an example of this type of change.
Physical change
This muscular organ of the digestive system churns food and mixes it with acid and enzymes.
Stomach
This is the side of the periodic table where most non-metals are found.
Right-hand side
This is the energy transformation that happens in a battery-powered torch.
____________-->___________-->______________
Chemical --> Electrical --> Light
The independent variable goes on this axis of a graph.
X Axis
This chart arranges all known elements in order of atomic number, in groups and periods.
Periodic table
These tubes in a plant’s stem carry water from the roots to the leaves.
Xylem
Carbon dioxide is this type of substance: an element, a compound or a mixture?
Compound
This is how much a component opposes the flow of electric current, measured in ohms.
Resistance
A light globe uses 100 J of electrical energy and produces 60 J of heat and 40 J of light. This is its efficiency.
40%
Installing this in the ceiling would most reduce the energy needed to heat a home in winter.
Insulation
These are the two products of photosynthesis.
Glucose and oxygen
These two words describe metals that can be hammered/bent into shape and drawn into wires.
Malleable and ductile
A light globe with a resistance of 3 Ω is connected to a 15 V battery. This is the current flowing through the globe.
5 A
A roller coaster cart has the most _____________ energy at the highest point on the track.
Gravitational Potential
Heart rate increased while exercising because muscles needed more of this gas.
Oxygen
