Engineering Planes


Today we built planes in school using card. It’s a balancing act! As with real airplanes there are 4 main forces, called aerodynamic forces, that enable a paper/cardboard plane to stay in the air:



Force
Description
Thrust
when you throw the plane forward 
Lift
is a force that acts on the wings and helps the plane to move up. Big wings increase lift 
Gravity
is the force that pulls the plane down. The right materials can create a lighter aircraft that stays up longer. 
Drag (caused by the tail)
is the opposite of thrust and it makes the plane slow down

The Land War This week we have been learning about Ireland in the late C19 including Michael Davitt, the infamous evictions and boycotting during post-famine life. As part of a drama lesson, different groups created freeze frames based around these harsh times. A landlord being ostracised The arrest of Michael Davitt A tenant farmer family about to be evicted Here we have students examining the freeze frames and trying to identify what exactly was happening in the scenes they were presented with.

The Land War- Notes from History Classes September 2019

Our Class Notes- M Goggin The Land War After the famine (1845-1849) LAND OWNERSHIP issues became central to political life in Ireland. The way in which Irish land was 1.              Owned 2.            Rented out 3.            Inherited had contributed to the appalling effects of the famine. In the late 1870s and early 1880s more bad harvests occurred. This lead to another threat of famine and landlords responded by evicting families. In response a new movement occurred- the  Irish National Land League -       Fight for the rights of small tenant farmers 3 Fs a.             Fair Rent b.             Fixity of Tenure c.             Freedom of Sale a.           Rent is in line with market price for land NOT the inflated price set by the landlord. b.           Rent agreement to state how long tenants could stay (gave security). c.           Tenants had rights when the land was sold Michael Davitt Founder of the National Land League
