‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍I‍‍‍‍‍‍f you have been assigned the role of Expert Group Member 1 - This is where you will put your contributions each week. Expert Group Member 1 tasks will be listed here. Hi Students, Please, where possible, rather than simply loading a Word doc, cut and paste the text into the wiki. If you are going to simply load a word doc - provide some introductory text on the wiki page to help others navigate the site and select the work they want to read. I realise that you may be loading files so that formatting is maintained. --Co-ordinator

Simone Langley - Expert Group 5 (member 1): I investigated the similarities and differences between reptiles and fish, below are the findings.



Emma Haack - Expert Group 1 (member 1): This week I looked at the difference in characteristics between Amphibians and Reptiles. I found that Amphibians and Reptiles have a very similar body make up. They both have a back-bone, are both cold-blooded animals and both have 4 legs (reptiles either have four legs or no legs - snakes). I created a Ven Diagram to show you the similarities and differences between the two animals. If you have any extra to add feel free to let me know.

I have also added a video explaining the difference - if you're more of a visual learner.

Natasha Armstrong - Expert group 2 I looked at the similarities and differences between mammals and reptiles. They do have some similarities - both being vertebrates (with a backbone), having a similar respiratory system breathing through their lungs, and they both produce sexually. However there are also several differences - mammals being warm blooded and reptiles being cold blooded, mammals staying with their parents after birth and reptiles immediately ready to go out on their own, and mammals having hair or fur while reptiles are covered in scales.

I have created a Venn Diagram to show the similarities and difference. There is room to add anymore that anyone can think of as well.



Christine Le Mesurier Group 4
Amphibians and Mammals Mammals have few similarities to amphibians compared to the number of differences they share. I Have inserted a Word Doc with the differences and similarities. The word doc also contains links to websites for further readings on mammals and amphibians. I have also included some you tube clips for our visual learners.

Fish Vs Mammals: Similarities and Differences

Lisa Whitaker – Group 3 I have investigated the differences and similarities between mammals and reptiles. The most interesting information I discovered about reptiles and mammals was both scales and hair/fur are made of keratin.

Lisa Whitaker -Group 3 This week I have looked at the introduction of cats. I have created a food web for before and after they were introduced.

Nyssa Stevens week 2 Acids and bases. Acids and bases are commonly found around the home and garden. In fact diluted acid is tart found in many foods like vinegar, wine, aspirin and citrus in weak amounts. Acid in its strongest form is used to make fertiliser and many other house hold products from paint to petroleum purifiers. Bases on the other hand are bitter and not usually eaten however there are a few exceptions including caffeine, nicotine, and sherbert. Bi-carb soda is also used to help neutralise stomach acid. Bases in their stronger form become lye soaps and caustic cleaners. Ph is important to farmers because organisms need specific ph levels in order to survive.



Nyssa Stevens Week 3 Liquid, solid, gas All matter can change state. Sometimes it takes massive temperatures or extreme pressure but it can be achieved. Matter in a solid state is usually denser than, matter in other states however in the case of water it expands as it turns into a solid due the way the molecules organize as it freezes. Pressure effects the temperatures needed for matter to change state. For example at high altitude water boils at a lower temperature. To turn a solid into a liquid; energy, usually heat is applied. This begins to excite the molecules and the molecules begin to move. Gas is formed when the molecules become so excited with latent energy that they start to break apart into separate h2o molecules. Water turns to steam when it gets to 100 degrees Celsius at average atmosphere and is invisible. This gas may evaporate and fall back to earth later as precipitation or condense on surfaces that adsorb the latent energy. The vapor you see is when the gas has reformed into tiny condensation droplets, these can be carried by Thermal Brownian motion until they reach a state of condensation and fall back to earth.

__**Briarne Edwards- Group 8**__ For this weeks group task, I have decided to investigate Mammals and Reptiles and their Similarities and Differences. There are many differences between Retiles and Mammals, However it was also noted that their are some simulates, obvious ones being the fact that both have 4 legs, a backbone and a tail etc. I have created a Venn diagram too dive into more detail about Retiles and Mammals and also attached to the word document is a link to a webpage which explains all different animals. (Venn diagram wouldn't load) **__ Reptiles __** **__ Mammals __** **__ Similarities __**
 * Dry and scaly skin
 * Breathes through its lungs
 * Reptiles are cold-blooded
 * Their body temperature stays the same as the outside temperature around them.
 * Most lay eggs
 * Three chambered heart
 * Mammals are warm blooded
 * Have fur or hair
 * At birth Mammals need the care of their parents
 * They have live birth
 * Have sweat glands
 * Vertebrates
 * They have vascular organ systems: Brains, hearts, lungs, ect
 * Both breath oxygen
