Insect mouthparts
Insect mouthparts
Insects exhibit a range of mouthparts, adapted to particular modes of feeding. The earliest insects had chewing mouthparts. Specialization has mostly been for piercing and sucking, although a range of specializations exist, as these modes of feeding have evolved a number of times (for example, mosquitoes (which are flies) and aphids (which are true bugs) both pierce and suck, however female mosquitoes feed on animal blood whereas aphids feed on plant fluids)
The development of insect mouthparts from the primitive chewing mouthparts of a grasshopper in the centre (A), to the lapping type (B) of a bee, the siphoning type (C) of a butterfly and the sucking type (D) of a female mosquito.

Snack culture
Mmm ... do you fancy a tasty bag of crisps? Or how about a yummy chocolate bar? British people love their snacks. Find out more about some popular British snacks. Don't read if you're hungry!
http://learnenglishteens.britishcouncil.org/uk-now/read-uk/snack-culture
Snack facts
Young people in Britain eat more snacks than people of the same age in other European countries. A recent survey has discovered that 64% of under 20-year-olds snack between meals. How does this compare with other countries? 58.7% of young people snack in Germany, 53% in France and only 40.7% in Spain. What are these young Brits eating? Savoury snacks, especially crisps, are the favourite snack in the UK.
Snack researchers found that the average person in Britain spends 43 pounds on savoury snacks each year, compared with 12 pounds for the French and only 7 pounds for the Italians. British people are spending a total of about 2.8 billion pounds a year on savoury snacks!
Crisps
What are crisps exactly? They are very thin slices of potato, cooked in oil then covered in salt or other salty flavours. British people are mad for crisps and they like them in a huge variety of flavours. Some of the most popular flavours include cheese and onion, salt and vinegar, steak and onion, roast chicken, tomato ketchup, and cheese and bacon.
A crisp-making company held a competition recently to find new exciting flavours for their crisps. The competition was called ‘Do us a flavour’ and the company received more than a million suggestions for new flavours. The finalists included squirrel flavour and onion bhaji flavour. The winner was builder’s breakfast, which tried to replicate the tastes of a full English breakfast including bacon, eggs, sausages and beans. The flavour was suggested by Emma Rushin of Belper, Derbyshire, who won £50,000 and 1% of future sales of her flavour. You can’t find builder’s breakfast crisps in the shops now – they were discontinued after one year. If you want to know what kind of crisps are most popular with people in the UK you can find a list on ‘The crisp list’ which describes itself as a website ‘for people who love crisps’
.Chocolate
The British love chocolate. In fact, they spend more on chocolate than any other European country! If you go to any newsagent’s shop in the UK you’ll see a huge selection of chocolate bars on sale. There is milk chocolate, dark chocolate and white chocolate. There are small bars of chocolate, medium-sized bars and massive bars of chocolate. You can buy mint-flavoured chocolate, chocolate-covered peanuts or raisins, chocolate with nuts, chocolate with toffee ... the list is endless! One brand of chocolate bar recently asked viewers to try four new flavours of a chocolate and then vote on Facebook for their favourite. The bar with
the most votes will be permanently added to their range.
Big chocolate eggs are sold in newsagents', sweet shops and supermarkets around Easter time. Parents, grandparents, aunts and uncles buy Easter eggs for children at this time of year.
Health
While crisps and other savoury snacks can be delicious, many people are worried that young people eat too many of these kinds of foods. The Food Standards Agency (FSA) is a government organisation that is responsible for food safety and food hygiene in the UK. The FSA issued a warning recently that many children's snacks contained dangerously high levels of salt.
Some parents are unhappy that their children can buy snack foods that are high in sugar, salt or fat such as sweets, biscuits and crisps from vending machines in schools. Some schools have banned these types of vending machines.
Advertising and marketing is another controversial area. Some people feel that advertising for junk food and unhealthy snacks should not be directed at children and teenagers. One opinion is that young people should be protected by a ban on this kind of advertising before 9 p.m. on TV and that there should be more controls over websites, sponsorship and in-store promotions. What do you think?

http://learnenglishteens.britishcouncil.org/uk-now/read-uk/school-dinners
School dinners (that means ‘lunch’) are a hot topic in the UK these days and there are lots of different opinions about what young people eat at lunchtime. Some people think that school meals are unhealthy, some people say that they are much better than in the past and others say that midday meals should be free for all school children.
What is a school dinner?
A typical school dinner costs about 2 pounds a day for a secondary pupil in the UK. There is usually a main course, a dessert and a drink. Parents often pay in advance online. School dinners must include food groups such as fruit and vegetables, protein (for example meat, fish or cheese) and carbohydrate (for example rice or pasta). There are rules about how the food is prepared, for example there are limits on the quantity of fried food.
Neverseconds – the school dinners blog
Martha Payne, from Scotland, started a blog called ‘Neverseconds’ about her school dinners when she was just nine years old. She posts photographs of her lunch every day and gives the food a grade out of ten. The grade depends on the quality and quantity of the food and how healthy it is. She doesn’t always give good grades. Her complaints include too much fried food, small quantities and hair in the food (yuck!). Many people read her blog and young people from all over the world post pictures of their school meals on Neverseconds.
Jamie
Oliver, the celebrity British chef, is passionate about school dinners.
He thinks that they need to be healthier and tastier. Jamie helped
to promote Martha’s blog by tweeting about it and Neverseconds
became very popular, very quickly on social media websites. On the
blog, Martha also collects money for charity. The money is used to
provide food for more than 600,000 poor children around the world.
Do
all children have school dinners? More than a third of British
school pupils have school dinner. Some take a packed lunch,
prepared at home. Others either have lunch at home or eat at nearby
take-away restaurants. We asked some young people to tell us about what
they eat at lunchtime on school days.
' I have school dinners most days but I take a packed lunch on Fridays. This Friday I had a cheese
sandwich, tomatoes, crisps, a chocolate bar and an apple juice.
’Tom, 14, Dorset
``Today we had pizza, salad, then an apple for dessert. I get free school meals because
my mum and dad are unemployed`
Rae, 13, Hathersage
`I had fish and chips today. I went to the chip shop near school with
some friends. Sometimes I takea packed lunch and sometimes my parents
give me money to buy lunch´
Theo, 15, Cambridge
I have school dinner every day. Today I had roast chicken, carrots, green beans and po
tatoes. For dessert I had cake.’
Sarah, 14,Birmingham
The future for school dinners
There are plans to examine school dinners in the UK and look at ways to make
them better. HenryDimbleby and John Vincent started ‘Leon’, a chain of restaurants
which aim to sell healthy fast food. The British government has asked the two
restaurant owners to collect information about school dinners and see how they
can be improved. Perhaps complaints about lunchtime food in British schools will
soon be a thing of the past.

Plant Cell Lab
http://biologycorner.com/worksheets/cell_lab_plant.html
Purpose: Students will observe plant cells using a light microscope. Two cells will be observed, one from the skin of an onion, and the other from a common aquarium water plant (anacharis). Students will compare both types of cells.Prelab Questions
1. What is the function of chloroplasts?2. Name two structures found in plant cells but not animal cells.
3. Name three structures found in plant cells AND in animal cells.
4. What structure surrounds the cell membrane (in plants) and gives the cell support.
Part A - Onion Cells
Part B - Elodea Cells
View a prepared slide of elodea (anacharis), which is an aquarium plant. As the slide warms from the light of the microscope, you may see the chloroplasts moving, a process called cytoplasmic streaming.Post Lab Questions
1. Describe the shape and the location of chloroplasts.2. Why were no chloroplasts found in the onion cells? (hint: think about where you find onions)
3. Which type of cell was smaller - the onion cells or the elodea cells?
4. Fill out theVenn Diagram below to show the differences and similarities between the onion cells and the elodea cells.
Photosynthesis.Investigating the rate of photosynthesis
http://www.bbc.co.uk/education/guides/zpwmxnb/revision/4
Plants make food using photosynthesis. This needs light, carbon dioxide and water. It produces glucose, and oxygen as a by-product. Leaves are adapted to carry out photosynthesis.
Plants make food using photosynthesis. This needs light, carbon dioxide and water. It produces glucose, and oxygen as a by-product. Leaves are adapted to carry out photosynthesis.
This is an example of a common
experiment used to investigate light intensity and the rate of
photosynthesis. This should help you understand how to work
scientifically.
Aim of the experiment:To use pondweed to see how light intensity affects the rate of photosynthesis.
Method
- Set up the apparatus as in the diagram.
- Leave for five minutes for the pondweed to acclimatise to the new light intensity.
- Count the number of bubbles given off in one minute.
- Move the light 10 cm further back.
- Leave for five minutes for the pondweed to acclimatise again.
- Count the number of bubbles given off in one minute.
- Repeat by moving the lamp away by 10 cm intervals until 50 cm is reached.
Variables
- Independent variable - the light intensity (how close the light is).
- Dependant variable - the number of oxygen bubbles given off (the rate of photosynthesis).
- Controlled variables - the size of the pondweed, the volume of water used and its temperature.
Risks:Care must be taken with glassware.
Expected results
| Distance from lamp to beaker (cm) | Number of bubbles given off per minute |
|---|---|
| 10 | 15 |
| 20 | 7 |
| 30 | 3 |
| 40 | 1 |
| 50 | 0 |
What the results mean
More oxygen bubbles are
produced when the light is closer to the beaker. So a greater light
intensity gives a greater rate of photosynthesis.
Evaluation
- Your measurements are accurate if they are close to their true value.
- Your measurements are precise if they are similar when completed again.
- Your experiment is repeatable if you get precise measurements when it is repeated.
- Your experiment is reproducible if others get precise measurements when they repeat it.

SUPER SIZE ME
http://www.teachwithmovies.org/guides/super-size-me.html
Description: Morgan Spurlock ate only food from McDonald's for 30 days: breakfast, lunch, and dinner. He was thoroughly tested by doctors before he started his "diet" and periodically tested throughout the 30 days. By the end of his experiment, the changes in his blood chemistry and the stress on his organs approximated the liver failure seen in advanced alcoholics; his cholesterol had risen to dangerous levels; and he had gained 24 lbs.
Rationale for Using the Movie: Super Size Me provides a humorous way to supplement a health class curriculum on nutrition, the dangers of convenience food, and the effects of advertising on consumer choices.
Objectives/Student Outcomes Using this Learning Guide: Through class discussion, research and writing assignments, student in both health and ELA classes will explore the issues of personal responsibility and the power of marketing tools over health issues, such as obesity, in society today.
