11 seps Biology class-  are task was to research the pros and cons of kidney transplant and kidney dialysis. We had to work individually or in groups of twos and threes. After finding our information we created powerpoints to show our ideas.

below is my groups ( Catherine, Damian and Aaron) Presentation

woodchurchscience is a brilliant site for news, views and resources for teachers and pupils studying ks3 and ks4 science in the uk. and best of all it’s maintained by my chemistry teacher mr warren here at woodchurch high school so he makes sure that there’s loads of relevant stuff on there to help with our studies and revision. i’m really hoping that we can improve on our second place position of 2007 and this year actually win the award for best resource sharing blog in the edublogs awards 2008.

With a new school on the way, Woodchurch High is trying to do its bit to help the environment. The school has appointed eco reps to help manage and control the new green scheme.

In every classroom there is now a grey recycling bin with a label on the lid educating students on what things they can or cannot recycle. Every week (or fortnight) a person from a form has to take the recycling bin to the recycling area where it is taken away to be recycled.

The school also has class rooms where there are no switches at all. the lights and computers are turned off automatically at the end of the day and during holidays to save electricity.

More updates on “green” progress soon!

Some quick questions to get you thinking…

What are you doing to help the escalating problem of climate change?

Do you think anything we need to do anything at all?

Who or what do you blame for the cause of climate change?

 Mitosis is the process by which a cell separates the chromosomes in its cell nucleus, into two identical sets in two daughter nuclei. It is generally followed immediately by cytokinesis, which divides the nuclei, cytoplasm, organelles and cell membrane into two daughter cells containing roughly equal shares of these cellular components.

Thousands of homes were affected by power cuts as the storms tore through the eastern state on Monday afternoon.

The southern city of Suffolk was among the hardest hit. Cars were flipped over, roofs blown off houses and trees and power lines brought down.

Officials have declared a state of emergency in the worst-affected areas.

 A Tornado forms when warm winds meet cooler winds, as the two winds move around each other a spiral of spinning air forms, this is know as a vortex . The vortex can spin at up to 300 mph. A wind that strong can destroy most things in its path. Objects, animals and even people have been picked up and hurled many miles away!

Below is a list of dangers straight from the Centre Of Responsible Nanotechnology website

 Molecular manufacturing (MM) will be a significant breakthrough, comparable perhaps to the Industrial Revolution—but compressed into a few years. This has the potential to disrupt many aspects of society and politics. The power of the technology may cause two competing nations to enter a disruptive and unstable arms race. Weapons and surveillance devices could be made small, cheap, powerful, and very numerous. Cheap manufacturing and duplication of designs could lead to economic upheaval. Overuse of inexpensive products could cause widespread environmental damage. Attempts to control these and other risks may lead to abusive restrictions, or create demand for a black market that would be very risky and almost impossible to stop; small nanofactories will be very easy to smuggle, and fully dangerous. There are numerous severe risks—including several different kinds of risk—that cannot all be prevented with the same approach. Simple, one-track solutions cannot work. The right answer is unlikely to evolve without careful planning.

Enzymes for Brewing Traditionally production of beer is by mixing crushed barley malt and hot water in large vessel known as mash copper. This process is known as ‘mashing’. Apart from malt, other starch-based cereals such as maize (corn), sorghum, rice and barley, or pure starch itself, are added to the mash. These are known as adjuncts. After mashing, the mash is filtered in a lauter tun and the liquid, known as ’sweet wort’, is then run off to the copper, where it is boiled with hops. The ‘hopped wort’ is cooled and transferred to the fermentation vessels where yeast is added. After the fermentation, the so-called ‘green beer’ is matured before the final filtration and bottling.

Liquefying Adjuncts

Adjuncts are used as an extra source of starch in brewing and usually consist of cereals. Protein also plays a vital role in fermentation by providing soluble nitrogen compounds that the yeast needs. Since the protein proportion in some types of adjunct is very small, it may be necessary to provide extra protein in the wort. This can be done by utilising the protein in the malt more efficiently. By adding a protein splitting (protease) enzyme, more protein can be solubilised and made available to the yeast.

In their natural form, starch­based cereals such as maize grits and rice are boiled before being added to the malt mash. The boiled (gelatinised) cereals are very viscous and need to be thinned (liquefied) before they can be pumped into the mash copper. This is done using an alpha amylase. Heat-stable alpha amylases are also available that are effective even at 100?C to ensure full liquefaction of the starch

Filtration

Slow rate of filtration is generally a problem when the mash is run off in the lauter tun and also during the final filtration of the beer. This is due to the presence of certain polysaccharides, mainly beta­glucans and pentosans, which are found in barley and poorly modified barley malt. The solution is to break down the beta­glucans using a beta­glucanase added during mashing or at the start of the fermentation process.

Maps offers a range of amylases, glucoamylase, proteases for distilling depending on the processes and applications.

WRAP ( Don’t Ask What It Stands For!) and The Composting Association will be encouraging everyone to ‘Green up their Environment’ this Compost Awareness Week, Sunday 4th May to Saturday 10th May. Gardening Celebs such as Charlie Dimmock and Matt James are enthusiastic about supporting WRAP and Compost Awareness Week.

In the next couple of weeks think about what YOU can do to help the planet become a greener place. Liturally!
