Form 4 Acceleration Homework

Please look at the following worksheet about PC Bacon and complete for next Wednesday at the latest:

Ban Dihydrogen Monoxide

The Invisible Killer
Dihydrogen monoxide is colourless, odorless, tasteless, and kills uncounted thousands of people every year. Most of these deaths are caused by accidental inhalation of DHMO vapour, but the dangers of dihydrogen monoxide do not end there. Prolonged exposure to its solid form causes severe tissue damage. Symptoms of DHMO ingestion can include excessive sweating and urination, and possibly a bloated feeling, nausea and vomiting. For those who have become dependent, DHMO withdrawal means certain death.
Dihydrogen monoxide:
* Is also known as hydroxyl acid, and is the major component of acid rain.
* Contributes to the "greenhouse effect."
* May cause severe burns.
* Contributes to the erosion of our natural landscape.
* Accelerates corrosion and rusting of many metals.
* May cause electrical failures and decreased effectiveness of car brakes.
* Has been found in tumors of cancer patients.

Contamination Is Reaching Epidemic Proportions!
Quantities of dihydrogen monoxide have been found in every stream, lake, and reservoir in the World. The pollution is global, and the contaminant has even been found in Antarctic ice. Despite the danger, dihydrogen monoxide is often used:
* As an industrial solvent and coolant.
* In nuclear power plants.
* In the production of styrofoam.
* As a fire retardant.
* In many forms of cruel animal research.
* In the distribution of pesticides. Even after washing, produce remains contaminated.
* As an additive in certain "junk-foods" and other food products.

Companies dump waste DHMO into rivers and the ocean, and nothing can be done to stop them because this practice is still legal. The impact on wildlife is extreme, and we cannot afford to ignore it any longer! Please do what you can to help!

Playing about with data

Please do the questions on the following 2 pages as this week's homework:

Physics Formulas

These are all of the formulas you should really know for your IGCSE exams. Its not a great copy, I'm afraid, but please note that only some of them are required for the core exams:



This following one is a bit better for coordinated science, and doesn't include all of the formulas on the sheet above:

Polymers

Please revise polymers and then test your understanding with these questions:

IB SL Questions on Human Physiology

Please revise all our work on human physiology and then try these IB-style questions:

Is it possible to see a prokaryote without a microscope?

Cracking

Plastics and polymers

Reproduction

Reproduction (Core)

Periodic Table

Just in case you haven't got one handy:

Chemical Tests

You are expected to know a number of chemical tests (including their expected results) for all of your exam papers, but they are especially likely to come up on paper 6. Please take the time to memorise all the tests on this sheet:

The Haber Process

The Electro-magnetic Spectrum

Radioactivity Keywords

I will be uploading as much stuff as I can over the next few days to help you with your revision - please keep up your effort all the way up to the exams. Things like the puzzle below can be printed and completed. Look out for revision pages. Look after your health and see you in a few days. Mike

Form 4 Forces

Hi everybody. While the school is closed, I will be leaving some work here for you to look at (not too much). Please print these pages to stick in your books, and please complete any questions I upload. Keep an eye out for other posts, and please also don't forget your project - building a machine to fire a ping pong ball as far as possible. look after yourselves and see you in a couple of weeks. Mike

Option D - Evolution

Please look at the following revision pages to help you with option D. Please note that I have only included the information relevant to standard level:

Important revision topics for GCSE

The attached powerpoint presentation goes through some of the more important topics you will be expected to remember from last year, whether you are doing combined or individual science subjects:

Important topics from form 4

Electrolysis

Please take a look at this link from BBC GCSE Bitesize and make notes about the electrolysis of solutions and melts. It is important to be able to predict what substances are produced at each electrode during electrolysis, so please make a note of the reactivity series of metals (and the position of hydrogen)

GCSE Bitesize - electrolysis

Walking with Cavemen

Please follow the link to the BBC website for their TV seies "Walking with Cavemen". Make notes on each of the species we discussed in class:

Walking with Cavemen

Which food produces the smelliest farts?

At last ..... a scientific study about what we all wanted to know:

The Truth about Dinosaurs and Birds

Speciation in Salamanders

Evolution occurs over timescales of millions of years, but there is evidence that it is occuring now (its just difficult to spot). Take a look at this excellent video clip where differences in the phenotypes of one species of Californian salamander are used to show they are undergoing speciation (in the process of becoming new species).
