Science+Matters

Hello 5-8 2011....
==How has the break been for you? My apologies that I have yet to upload your holiday homework. Really busy with planning for next year....so sorry. Here are the instructions: ==

==Do a presentation of your research. Alternatively you can present your learning in the form of a scrap book. Some links that I've found are listed below. You can use information from other websites or sources..... the list is not exhaustive. ==

[] []

SYSTEMS:

 * 1) ==Human Respiratory and Circulatory System ==
 * 2) ==Plant transport system ==
 * 3) ==Cells ==
 * 4) ==Electric System ==

CYCLES:

 * 1) ==Water ==
 * 2) ==Plant reproduction ==
 * 3) ==Human reproduction ==

P3 & 4 Revision Topics:

 * 1) ==Diversity of Living things ==
 * 2) ==Diversity of Materials ==
 * 3) ==Cycles in Plants and Animals ==
 * 4) ==<span style="color: #ff5300; font-family: 'Comic Sans MS',cursive;">Matter ==
 * 5) ==<span style="color: #ff5300; font-family: 'Comic Sans MS',cursive;">Magnet ==
 * 6) ==<span style="color: #ff5300; font-family: 'Comic Sans MS',cursive;">Heat ==
 * 7) ==<span style="color: #ff5300; font-family: 'Comic Sans MS',cursive;">Light ==

<span style="color: #ff5300; font-family: 'Comic Sans MS',cursive;">When studying these topics, try to see the Relationships between related topics. For E.g:
==<span style="color: #ff5300; font-family: 'Comic Sans MS',cursive;">1. How are the different systems in the body integrated (work together) to carry out life processes? (circulatory, respiratory and digestion) ==

<span style="color: #ff0000; font-family: 'Comic Sans MS',cursive;">Quite a number of school holidays coming up and I do not wish to spoil your mood but be prepared, for your CA2 is approaching. Topics include Human reproduction system and Water cycle. So let's all do a good job with this topic ok?

<span style="color: #ff0000; font-family: 'Comic Sans MS',cursive;">For the coming week, I hope everyone would have submitted your 'bundles' of PSLE Revision papers and the concept map. You are supposed to email to trpoon@yahoo.com or print it out to submit. Please don't make me chase you for it, the usual few....

<span style="color: #ff5300; font-family: 'Comic Sans MS',cursive;">Dear 5i*hters,

<span style="color: #ff5300; font-family: 'Comic Sans MS',cursive;">I am appealing on behalf of some of your friends participating in SolarPrix. Remember the last time I requested for all of us to look at our old toys and the storeroom to see if there are any usable spare parts such as tyres and gears? <span style="color: #ff5300; font-family: 'Comic Sans MS',cursive; font-size: 12px; line-height: normal;">Now that the exams are over, I hope we can spare some time to ransack our rooms, and locate the treasures that may come in handy for the teams. The SolarPrix Builders have identified some materials that they need, namely:

<span style="color: #ff5300; font-family: 'Comic Sans MS',cursive; font-size: 12px; line-height: normal;">1. 10 cm metal rod (diameter of no more than 5 mm, I think... please check with Zhenglong) <span style="color: #ff5300; font-family: 'Comic Sans MS',cursive; font-size: 12px; line-height: normal;">2. Gears (requested by Joel, Verrin and Aleena) <span style="color: #ff5300; font-family: 'Comic Sans MS',cursive; font-size: 12px; line-height: normal;">3. Wheels (requested by Joel, Verrin and Aleena)

<span style="color: #ff5300; font-family: 'Comic Sans MS',cursive; font-size: 12px; line-height: normal;">So shall we share resources and play a part to help 5/8 SolarPrix Builders? = = <span style="color: #ff5300; font-family: 'Comic Sans MS',cursive;">cheers <span style="color: #ff5300; font-family: 'Comic Sans MS',cursive;">Ms Poon =<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">27 May 2011 = =<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">Dear children = ===<span style="color: #800080; font-family: 'Comic Sans MS',cursive;">I've read from the forum that some of you have difficulties understanding some of the concepts in Electrical systems. Don't worry. Below are some links to reinforce the things we talked about in the classroom. Post you questions in the forum and let's discuss. ===

===When you're in the dark and you want to see, You need uh... **Electricity, Electricity** Flip that switch and what do you get? You get uh... **Electricity, Electricity** Every room can now be lit With just uh... **Electricity, Electricity**===

Turn that generator by any means, You're making uh... **Electricity, Electricity!**
Now, if we only had a superhero who could stand here and turn the generator real fast, then we wouldn't need to burn so much fuel to make... electricity.
 * A generator is a machine that contains a powerful magnet that creates a magnetic field. When wires are rotated rapidly through this field, then a current of electricity is produced.**

 * <span style="color: #2e981b; font-family: 'Comic Sans MS',cursive;">Hi kids **


 * <span style="color: #2e981b; font-family: 'Comic Sans MS',cursive;">Wow! It's been a term since we started 2011. Finally we are at the term break. I hope you guys get to rest a bit more and be recharged for the new term. Remember the project I asked you to do? Create a 3-D model of either a plant cell or animal cell (even both if you like) using recycleable materials. **


 * <span style="color: #2e981b; font-family: 'Comic Sans MS',cursive;">Try to read up more on the functions of the different parts in the cells first so that you can choose your materials wisely that suit the nature of the parts. Try to look into your store-room or even trash bin for materials that your family members have thrown away as they clean up their rooms during this break, e.g. plastic book covers, old sponge, old fabric pieces, buttons, expired hair gel.....haha.....(use a bit of creativity and almost anything can be used to make your model!!!) **
 * <span style="color: #2e981b; font-family: 'Comic Sans MS',cursive;">If you are still brain stretched, try google "3-D cell model" you should find a lot of links.......but try excercising your brain cells first ok? **


 * <span style="color: #2e981b; font-family: 'Comic Sans MS',cursive;">Have Fun! **

<span style="font-family: 'Comic Sans MS',cursive;">Hi Kids

<span style="font-family: 'Comic Sans MS',cursive;">There is this interesting programme organised by NUS and RVH, =<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">[|Nature Explorers' Programme]. =

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">Let me know how many of you will be interested. There are a lot of activities to increase your knowledge on the plants and animals around us. Note the schedule and deadlines for workshops and project submission. I will be joining you for the workshops/ fieldtrips and helping you with the projects if need be. However, there is a certain level of commitment. So 5i8ters, I expect perseverance through the programme if you so decide to embark on it.
