I like this web page because it has a lot of information about energy, it is complete and there are new things that I did not know. (by Raquel Schulz 2nd ESO)

http://powermin.nic.in/kids/types_of_energy.htm

This page is about five different types of energy. Each has a picture, so as to make one an idea of what it is, and an explanation.

After the explanation of the different types of energy, there is a paragraph saying that when energy is used it is changed into another type of energy, and it explains this with a short example.

In my opinion, I think that this page is a good one because of the explanations it gives, but it could improve a little by putting more information or somthing like that. (Antònia Galmés, 2nd ESO)


http://www.fi.edu/guide/hughes/energyconservation.html

This page talks about the conservation of energy. It explains that energy cannot be created nor destroyed, it can only be transformed from one type to another.

There are two examples of a bulb, that changes electrical energy into light energy and into heat energy.

In my opinion, this page is a little bit too scientific for us, but for a person that has to study this unit, the example and the explanation are very clear. (Antònia Galmés, 2nd ESO)

This page contains all the properties of metals and non-metals: appearance, melting and boiling points, density, strength, malleability, ductility, heat conductivity, electrical conductivity and nature of oxides.

In my opinion, it could be better, because it only explains the properties of metals and non-metals, but I think that they are well explained, so it is good to study from this page. (Antònia Galmés, 2nd ESO)

http://www.bgfl.org/bgfl/custom/resources_ftp/client_ftp/ks3/science/acids/

When you open this page, you can see the pH scale with the numbers and their colours. Below the pH scale, there are three links: litmus reactions, universal indicator reactions and neutralisation. If you click on one of them, you go to another page that is a little explanation of the unit you have clicked, and under the explanation, you have things (beaker, universal indicator paper, ...) and substances (vinegar, oven cleaner, ...) and you have to say if they are acids or an alkalis, and then, test them.

In my opinion, these page is very good because you can study while you are ‘playing’. (Antònia Galmés, 2nd ESO)

Then, it explains two examples of balanced forces: an arm wrestling competition with someone and a tug of war, and it says why this happens. After these two examples of balanced forces, there are three examples of unbalanced forces. At the end of the page, there are some problems to practice what has been explained before about balanced and unbalanced forces.

In my opinion, this page is a good one to learn about balanced and unbalanced forces, because there are examples, and I think that with examples you undersand it better, and because it doesn’t use difficult words and examples. (Antònia Galmés, 2nd ESO)

http://www.epa.gov/climatechange/kids/greenhouse.html

This page explains the Greenhouse Effect. It explains which gases cause this phenomenon and how much colder would the earth be without the Greenhouse Effect.

Below the definition of the Greenhouse Effect, there is a photo that represents a greenhouse, and it explains that it works exactly the same as the Greenhouse Effect.

There is another photo of the Greenhouse Effect in the atmosphere. It says that the Greenhouse Effect is important because without it, the Earth would not be warmer enough for humans to live, but if it becomes stronger, it may cause problems for humans, animals and plants.

At the left side of these page, there are some links about the climate, and at the top of the page, there is a link of games, to help us find out how much we know about Climate Change.

In my opinion, this page is fine because it explains the Greenhouse Effect, first with the example of a greenhouse, and then, with the atmosphere. (Antònia Galmés, 2nd ESO)


http://volcano.und.edu/vwdocs/vwlessons/plate_tectonics/introduction.html

This page explains plate tectonics. It says that it is a new theory. According to this theory, they think that the Earth's surface is broken into large plates, and the size and the position of the plates changes over time.

It explains that when they move against each other, there are sites of intense geologic activity, such as earthquakes, volcanoes, and mountain building. It says that there are different locations and types of plate boundaries.

In my opinion, this page is a little poor but to begin a unit or to briefly explain what plate tectonics are, it is fine. (Antònia Galmés, 2nd ESO)
