**Bearings**Learning Intentions To understand what a bearing is To be able to work out and measure bearings Success Criteria - By your next lesson To be able to explain what a bearing is and why we use them. To be able to say what the 3 key points are.**Estimating Angles**The Competition!! Starter**The Rules of the game!**An angle will appear on the screen, your job is to estimate the size of the angle. The winner is the person who gets the most points. • All angles are a multiple of 5. • If you guess the angle exactly right give yourself 3 points. • If you are 5° out give yourself 2 point. • If you are 10° out give yourself 1 point. • You will have 30 seconds to guess – then the answer will come up. Hint**Estimate the Angle**10° - 1 point 15° - 2 points 20° - 3 points 25° - 2 points 30° - 1 point THE POINTS**Estimate the Angle**140° - 1 point 145° - 2 points 150° - 3 points 155° - 2 points 160° - 1 point THE POINTS**Estimate the Angle**125° - 1 point 130° - 2 points 135° - 3 points 140° - 2 points 145° - 1 point THE POINTS**Estimate the Angle**60° - 1 point 65° - 2 points 70° - 3 points 75° - 2 points 80° - 1 point THE POINTS**Estimate the Angle**90° - 1 point 95° - 2 points 100° - 3 points 105° - 2 points 110° - 1 point THE POINTS**BEARINGS**WHAT’S THE POINT?**Compass points**360° 000° N 045° 315° NW NE E 270° W 090° SW SE 225° 135° S 180°**Bearings – The Key Points**Bearings are a measure of direction taken from North. Bearings are always measured in a clockwisedirection Bearings are always written in 3 figures. from North. clockwise 3 figures**Example 1: What is the compass direction from Belfast to**Omagh? ……………………What is the bearing from Belfast to Omagh? …………………… West from Belfast 270° Omagh Belfast North**Example 2: What is the rough compass direction from Omagh to**Newry? ……………………What is the bearing from Omagh to Newry? …………………… South East from Omagh 125° Omagh North Newry**Example 3: What is the rough compass direction from Omagh to**Sligo? ……………………What is the bearing from Omagh to Sligo? …………………… South West from Omagh 245° North Sligo**(1a) Measure the bearing of B from A**(1b) Measure the bearing of A from B (b) Measure the bearing of A from B (2a) Measure the bearing of D from C (2b) Measure the bearing of C from D (b) Measure the bearing of A from B 145° 045° 325° 225° ° C ° B ° D ° A**Question 3**• Measure the bearing from Banbury to Catford = ……………..° • Measure the bearing from Catford to Art = ……………..° • Measure the bearing from Banbury to Art = ……………..° • Measure the bearing from Art to Banbury = ……………..° • (b) Measure the bearing of A from B 130° 270° 238° 59° ° Banbury ° Art ° Catford**Question 4**North G Measure the bearings of the following E = …………° N= …………° J = …………° O = …………° Y = …………° Which letter is on bearing of 072 ° = ……… 050 ° = ……… 320 ° = ……… 243 ° = ……… N E 50° 310° 280° M J 220° 290° M T E D N O W T Q Y**PlenaryFlight EZY551 projected flight to Quebec is shown.But**the flight hits problems with the volcanic ash from Iceland and is diverted to Prince Edward Island – what is the new bearing.**Clockwise from the plane to Prince Edward Island I have**measured the angle and it is 115° Bearing =115° Angle is marked on the diagram and is 245° Tick or TrashFlight EZY551 projected flight to Quebec is shown.But the flight hits problems with the volcanic ash from Iceland and is diverted to Prince Edward Island – what is the new bearing.
