We agreed that plants only need leaves to absorb sunlight and carbon dioxide for photosynthesis. They actually prevent water entering them, except from the roots via the stem and veins.</div>

The key parts of the leaf cross-section that we were encouraged to talk about were: wax cuticle, palisade cells, air spaces, stoma, guard cells, and the spongy mesophyll.</div>

<br />
<h4>
<span style="color: magenta;">STEP ONE: Method Described (Multistructural)</span></h4>
<div>
<ol>
<li>180-190g of strained soil is weighed and added to a biodegradable punnet.</li>
<li>Three 2cm deep wells are made in the soil (evenly spaced out).</li>
<li>One sugar snap pea seed is put into each well. The wells are covered with soil.</li>
<li>20mL of tap water is measured in a measuring cylinder then added evenly to the top of the soil.</li>
<li>The class's punnets are put in trays and placed in the window of the resource room.</li>
<li>20mL of tap water will be added every Monday and every Friday.</li>
<li>The height of the plants will be recorded on Monday every week for 6 weeks.</li>
</ol>
<div>
We have yet to decide how to investigate the effect of the plant nutrient additives we have purchased - this is tomorrow's job!</div>
</div>
<div>
<br /></div>
<h4>
<span style="color: magenta;">STEP TWO: Variables Analysed (Relational)</span></h4>
<div>
Mr Nicoll identified some key variables that were controlled by using this method. We then discussed why it was important to control these variables:</div>

They needed to find out about its habitat, adaptations, place in a food web, and about its chances of survival. The following links are some of the websites/blogs which were made. Other students presented their findings as: written reports, posters, speeches, or on display boards.<br />

Food chains represent the energy flow and feeding relationships between a group of organisms in a particular habitat or ecosystem:<br />

All food chains start with a producer. They are able to make their own food using sunlight, carbon dioxide and water; this process is called photosynthesis.</div>

We have been separating them into their <i>pure substances</i>.<br />
<br />
Today, we learned what some of those pure substances are:<br />
<br />
<ul>
<li>elements</li>
<li>compounds</li>
</ul>
<div class="separator" style="clear: both; text-align: center;">

<div>
<br /></div>
<div>
<br /></div>
<div>
Some elements exist as atoms, while some exist as molecules. The elements are all found on the <a href="http://www.webelements.com/">Periodic Table</a>, which has their special symbol.</div>
<div>
<br /></div>
<div>
Compounds are formed when <i>different</i> elements <i>react</i>. This means they join together chemically, forming bonds between the atoms. Compounds can be molecules (like some elements) or they can be ionic. We learn more about these in the next few years of Science and Chemistry...</div>
<div>
<br /></div>
<div>
Our task today was to <i>classify</i> all matter from what we have learned in the last few weeks and in today's lesson.</div>

<br />
"Decantation is a very quick method for separating a mixture of a liquid
and a heavier solid. This works by first letting the solid settle on the bottom
of the beaker, and then you can pour the water off the top of the solid without
disturbing it. The advantage of decantation is that it is very quick, but it is
also rough and does not always work the way it is meant to. It cannot be used
to separate a mixture of a liquid and a light solid, like sawdust and water.
The particles of sawdust are suspended in the water. They are so light that
they do not sink down to the bottom for a long time.<br />
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span lang="EN-US">Filtering is a very good method used to separate solids from liquid.
This method works by placing a sieve or micron paper over a container or beaker
and pouring the mixture onto the filter. The filter separates the solid from
the liquid and the liquid passes through without carrying the solid. For
example with the sawdust experiment, the sawdust stayed on top of the filter
paper while the water passed through. This is because the sawdust bits are too
big to fit through the paper, but the water is not, so it passes right through.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span lang="EN-US">A Centrifuge is a piece of equipment, usually driven by an electric
motor, though some older models were spun by hand. The Centrifuge puts an object
in rotation around a fixed axis, applying a force perpendicular to the axis. A
Centrifuge is also used to separate the components of blood in blood banks. A
Centrifuge is the most efficient type of filter, but it lacks portability and
simple nature. You cannot just go out camping and take a centrifuge with you.
First is requires a power source, and secondly it is too big to just chuck in
your backpack.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span lang="EN-US">In my personal opinion, I think that the paper filter is the best
option. I think this because this method is easy to carry out, it can be
carried out nearly anywhere, it does not require a power source to be
performed, and it is also very efficient. Using a 1-micron paper filter you can
remove harmful diseases from water is you are out tramping and avoid becoming
severely ill. Although a paper filter is a very good option, it is not always
the best. If you were cooking potatoes or pasta it would just be so much easier
to apply decantation. Also if you are giving blood it is much quicker and
easier to use a Centrifuge to separate the different parts of blood rather that
using paper.<span style="font-size: medium;"><o:p></o:p></span></span></div>

If substances are soluble, they dissolve to make a solution. Some solutions have a lot of solute in them - we call these concentrated. Some have very little solute in them - we call these dilute.<br />
<br />
How easily something dissolves is called its solubility. Some substances dissolve very easily (so have high solubility). Some are difficult to dissolve (so have low solubility).<br />

There are three possible ways to separate suspensions:<br />
<br />
<ol>
<li>decanting</li>
<li>filtering</li>
<li>centrifuging</li>
</ol>

In today's lesson, we had to decide which method is <u>the best</u>. Is there actually a "best" method. We used <i>research, an experiment (p29) and a case study (p30)</i> to help with this.</div>

These are a little different to the primary colours of paint. This is because paint reflects fewer colours when we mix the colours together. This is called colour subtraction. On the other hand, when we mix the primary colours of light, we <i>add</i> the colours, so <i>more</i> light is let through.<br />
<br />
Then, we had to do some research and produce a report or poster about one of the following topics:<br />
<br />
<div style="text-align: center;">
<br /></div>
<ul>
<li>How do we see colours?</li>
<li>How does theatre lighting work?</li>
<li>How do televisions work?</li>

Lenses use refraction to change the image size. Lenses are curved and classified as either <i>concave </i>or <i>convex</i>. Convex lenses are used as magnifying glasses, while concave lenses make things smaller. Convex lenses focus light on a point called the <i>focus</i>.<br />

Here is an experiment we did in class about lights and water.<br />
<br />
It is just a trick, but how does it work...?!Anonymoushttp://www.blogger.com/profile/02598497834943693912noreply@blogger.com0tag:blogger.com,1999:blog-8253699965572226574.post-52193300547723783902013-04-03T11:38:00.000+13:002013-04-03T11:38:34.619+13:00ShadowsToday we started our light topic. We watched this video, then got to make our own shadow puppets.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<object width="320" height="266" class="BLOGGER-youtube-video" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" data-thumbnail-src="http://img.youtube.com/vi/EAQxNVQF_I0/0.jpg"><param name="movie" value="http://youtube.googleapis.com/v/EAQxNVQF_I0&source=uds" /><param name="bgcolor" value="#FFFFFF" /><param name="allowFullScreen" value="true" /><embed width="320" height="266" src="http://youtube.googleapis.com/v/EAQxNVQF_I0&source=uds" type="application/x-shockwave-flash" allowfullscreen="true"></embed></object></div>
<br />
We were asked a few questions:<br />
<br />
<ol>
<li>How do you make the puppets bigger/smaller?</li>
<li>How does this work?</li>
<li>What do shadows tell us about light rays?</li>
<li>How do we use shadows in everyday life? OR How do we stop shadows causing problems in everyday life?</li>
</ol>
