The Anglo-Saxon England

Image
 Over the past few history lessons, we have been looking at the Anglo-Saxons.  We originally started our search with local history, when we heard about the Battle of Bentfleet (894): a burnt viking boat had been dug up near Haleigh along with a few skeletons and swords. Historians believe that the vikings had made their stronghold on top of Haleigh hill and moored their bouts in the river near by when someone set fire to one (or more) of the boats. We know that a battle then took place because of the bodies and the swords found there, so we theorised that the vikings had an enemy near by, possibly in Kent who sailed over the Thames, and they had attempted to sabotage them. Only the vikings saw from their hill and came to fight them off, the battle then ensued. We decided after researching this battle, that we wanted to look into Vikings and Anglo-Saxon Britain We created a timeline spanning 600 years, where we outlined what we had found out about Anglo-Saxon Britain. This started with

Pendulum Painting

Image
 Today, we created art by dangling a cup full of water and paint over a piece of paper. This technique is called pendulum painting and it relates to us later looking into harmonographs. After watching a few videos on YouTube about how to make a piece of art using a pendulum we set up one in our back garden, we did this by punching holes through a cup, threading string through it and finally, hanging it off of our washing line. We then (to protect the patio) put down an old bed sheet and got two A3 papers and taped them flat.  Once everything was in place, it was time for the paint. We chose black paint, since we had white paper, and used a phone to get a video to record our findings. Unfortunately, our first attempt was not very successful because instead of clean lines we got paint splatters. We thought that maybe the paint was too thick so we worked out the ratio 1:2 (One being paint and two being water) and set up attempt number two.  Our second attempt worked a lot better than the

Stomata Structure and Function

Image
A few days ago we painted the underside of leaves in clear nail polish to see if we could see the stomata once we peeled them off. The nail varnish coated the underside of the leaf and sank into the stomata and formed "dips"  We then painted the nail varnish with blue food colouring which sank into the diops showing there the stomata are on the leaf.  Although this project didn't work very well it gave us the idea to look at leaves and red onions through a microscope.  Stomata are little pores on the underside of leaves that play a crucial role in photosynthesis, they are where waste is expelled from the plant (oxygen, excess water and carbon dioxide ect.) Each stoma (singular form of stomata) can be opened and closed when necessary. This is because of the guard cells either side of the stoma. The guard cells are two cells either side of the stoma and act as doors that open and close, when the guard cells are turgid (firm) the stoma stays open, when they become flaccid (l

Microscope Magic

Image
 Today we looked at plant cells under a computer microscope. We found that best results were from red onions because we could clearly see the different cells.  After looking at the photographs, we observed that the cells were very regular in size (either a squashy rectangle or oval) believe that this is because of the rigid cell walls that plant cells have.  magnified x150 magnified x100 We tried a few other plants but didn't have as much success seeing the cell walls. However, we do have some interesting photographs of close-up sunflower leaves and petals.

La Vie en Rose

Image
La Vie en Rose was made famous by Edith Piaf in the nineteen forties. A year later, Louis Armstrong recorded his version. Piaf sang in french, whilst Armstrong recorded a fairly loose translation implied to be from the man's perspective.  Piaf's Lyrics Our Translation Armstrong's Lyrics Des yeux qui font baisser les miens Un rire qui se perd sur sa bouche Voilà le portrait sans retouches De l'homme auquel j'appartiens     Quand il me prend dans ses bras Il me parle tout bas Je vois la vie en rose Il me dit des mots d'amour Des mots de tous les jours Et ça me fait quelque chose Il est entré dans mon cÅ“ur Une part de bonheur Dont je connais la cause C'est lui pour moi, moi pour lui dans la vie Il me l'a dit, l'a juré pour la vie Et dès que je l'aperçois Alors je sens en moi Mon cÅ“ur qui bat Des nuits d'amour à plus finir Un grand bonheur qui prend sa place Des ennuis, des c
