Flick a 5th marble to hit one end of the line of marbles.
Questions:
What happens to the marbles which are hit by the 5th marble?
What does this show us about how sound travels?
Sound – Experiment Two
How does sound travel?
Apparatus: cardboard tube 3 candles plastic bag rubber bands
Method:
Stretch plastic over both ends of the cardboard tube.
Secure the plastic with rubber bands.
Make a small hole in the plastic at one end only.
Plant the three candles in soil, equal distance apart.
Point the cardboard tube towards the candles, with the hole end closest to them.
Tap the other end of the plastic with finger tips
Questions:
What happens to the candles?
What does this tell us about how sound travels?
What happens when the tube is moved closer or further from the candles?
Sound – Experiment Three
How does Pitch and Volume affect sound?
Apparatus: bowl, plastic large rubber bands sugar baking tray spoon
Other noise makers
Method:
Stretch plastic tightly across bowl.
Secure with rubber bands.
Sprinkle sugar on top of plastic.
Make a high sound.
Observe what happens to the sugar.
Questions:
What happens when you move the sound closer or further from the bowl?
Do different pitches or volumes create different result?
Draw the patterns of what you see.
This would have been a great science fair idea!
Hey there fellow Mad Scientist’s _ I need your help again. Next week we are going to be having an assessment task for Science – But to be successful we will have to learn a lot more, in a short space of time. SO – here is your challenge:
On the yellow cards there are a number of science experiments that might help us answer some of our questions – check out the cards and carry out some of the experiments. You may need to bring things form home for some of them, so be organised the day before.
I have put some links on the wiki all about light. Have a look at these and see if you can find some key information that will help us with our understanding.
On the window are some interesting words – a clue is that you will need to understand all of these, and use them in your writing of the conclusions.
I have created a wiki page for us to share information - remember the rules about adding to a page - lets see how clever we can be!!!!!
Kinetic energy is a form of energy used in a motion. Any object that involves a motion has kinetic energy. There are many forms of kinetic energy such as vibrational, rotational and translational. We think nuclear energy is a radioactive source of power that can be natural or man-made. Natural nuclear energy is created by the sun and the stars. Man-made is made by nuclear power plants that create electricity. Sound energy is that is produced by a wave of vibrations in a specific material. The bigger the force of the waves the sound will vary by between loud and soft. Sound travels at different speeds. When it travels through solids it goes faster because it is more dense but when travelling through liquids and gases it is a lot slower because the object is not so dense. By Tayla-Jay Dearlove and Bailey Mackie Potential energy An object can store energy as the result of its position. When the object is elevated it is full of energy. Dakota and Bryan.
Questions we have about light (9th August):
Can you check the wattage of the sun?
What is wattage?
How do we measure light?
Why do we see yellow light?
Why do light sources give off heat?
Why is the shadow bigger than the actual object?
Why does light travel so fast?
Would your shadow change if the light source was a different wattage?
Why does light stop at an object?
Why does light travel in straight lines?
Why are shadows black and not any other colour?
Why is light see through and not solid?
How does a light bulb work?
Would two equal lights cancel out each others shadows out?

http://misscienceteacher.wetpaint.com/ this is a website that will provide all the info you will need to be successful with your science fair project. Over then next few weeks we will be learning how to set out a correct investigation, but this link will help you with the process.
I am sorry the above link is not working for some people. Here are the key documents:

Try out these online activities around light - record in your science book any key ideas you discover. You guys have created some amazing birds! Here is a sample of a few of them:
Teaching to focus on Students being able to…
Explain what it means to be a living thing.
Understand what mutually exclusive categories are.
Explain why animals develop adaptations.
Understand that many adaptations which animals developed will be dependent on where they are on the food chain.
Explain that animals live in niches to suit their particular lifestyle.
Explain that animals avoid competition by adapting to certain niches, in order to better survive.

Challange yourself with a light quizSites that will help you as your explore the science behind light
there are different types of energy!
Can you PLEASE help me understand what it all means?????
*Thermal
*Chemical
*Kinetic
*Potential
*Magnetic
*Sound
*Electric
*Mechanical
*Nuclear
