STEM Concepts
100

The luff of the main sail gets fastened to this.

MAST

100

This is the location on a boat from where the skipper steers the boat.

HELM

100

Sailing upwind, or sailing to windward, this is the closest course to the wind that you can sail on the edge of the no-go zone.

CLOSE HAUL (BEATING)

100

The ship's wheel is an example of this simple machine.

WHEEL AND AXEL

100

This principle states that within the flow of a fluid, like a liquid or a gas, an increase in the speed of the fluid occurs simultaneously with a decrease in pressure.

BERNOULLI'S PRINCIPLE OF LIFT

200

This is a hydrofoil that in essence steers the ship.

RUDDER

200

This is the forward end of the sailboat.

BOW

200

A 90° area that's too close to the wind to sail in effectively.

IN IRONS (NO-GO ZONE)

200

The steps on a boat are an example of this simple machine.

INCLINED PLANE

200

Terms such as buoyancy, density and displacement are used to describe this STEM concept.

FLOTATION

300

The foot of the mainsail gets fastened to this.

BOOM

300

This is the aft end of the sailboat.

STERN

300

The boat is sailing away from the wind, with the wind coming from behind the boat, but not directly behind.

BROAD REACH
300

The tiller is an example of this simple machine.

LEVER

300

The heating and cooling of the earth's land and sea masses on a daily basis are used to explain this STEM concept.

LAND AND SEA BREEZES

400

This is used to reposition the boom in order to adjust the angle of the main sail.

MAIN SHEET

400

This is the left side of the sailboat when looking forward.

PORT

400

The boat is sailing directly downwind, with the wind coming from behind.

RUN

400

The blocks used on a sailboat are an example of this simple machine.

PULLEY

400

Terms such as anemometer, knots, direction are used to describe this STEM concept.

WIND POWER

500

These are the lines used to adjust the trim of the different sails.

SHEETS

500

This is the right side of the sailboat when looking forward.

STARBOARD

500

The wind comes across the boat at a 90° angle, perpendicular to the wind direction.

BEAM REACH

500

A winch and a propeller are examples of this simple machine.

SCREW

500

Terms such as turbidity, salinity and temperature are used to describe this STEM concept.
