Griffin has found an Astrolabe in the town libary. He doesn't  know how to use it and he needs our help.
 
Firstly, I needed something to measure so I measured the height of the goal post.

Secondly, I had a friend to help me measure the correct height of the goal post.

Look through the straw to the top of the goal post.  First before we measure we must know that the key angle is 45 degrees. With your string line move backwards and forwards while looking through the straw  until the string line rests on 45 degrees.  Measure from where you are standing to the goal post.  Measure your eye height from the ground and add these two measurements.  The total will be the height of the goal posts.

Isabella is taking a visit to the Haggle, before she enters she must hand in a sack full of goodies. She has a choice of sack in sack one we have a snorkel, spear gun, guitar, tooth paste, i Pod, and a gemstone necklace. In sack two we have a deck of cards, seven cans of peach slices, life jacket bow and arowws, binoculars and a  water filter. 
Sack one has many useful items such as;
A snorkel to look under water and could be useful under water to catch fish with your Spear gun, Guitar,to entertain young children, Tooth paste to keep you teeth clean. how ever i find that sack one also has unuseful itmes such as;iPod great to have and use while you have it but pointless with out a charger, The gemstone necklclace wont help the kids survive in grimsdon.
scak two also has useful items like;Deck of cards good to keep you entertained, 7 cans of peach slices good to use for a snack, Life jacket for the little ones in the big bath and also incase you fall of the ante trope, Water filter so you have nice clean water. 
in sack two we also have some unuseful items;
binoculars there not relly helpful and wont help the kids survive

I find that Isabella should keep sack two for the palace as it has many useful items.
