croaking frogs
Yesterday after lunch I could the frogs croaking.
Please write a paragraph on each of the following questions:
What special features do frogs have?
Do they all have the same type of feet?
What do frogs eat?
How do frogs’ features help them to survive?
How are frogs different to other animals? How are frogs similar to other animals?
How many fingers and toes do frogs have?
What is the difference between frogs and toads?

Fabulous Frogs!
This term our science topic is
We are going to learn about the frogs that can be found in our local area about their habitat.
To start we are going to explore the ponds (puddles!!!) around our school and see if we can find some frogs. We can certainly hear them, hopefully we will be able to observe some too!
Here's two photos I took of a frog that Jack found in the school yard on Tuesdsay.
Here is a picture of the frog that we found on our walk around the school yard today.
The following website will help you to identify the frogs that we found in our school yard.
Frogs of Australia
Here are some websites that you will need to explore to find information for today's lesson.
Frogs and Toads

And here are some crazy frog websites and games.

Science Games
Here are some on-line science games

Accuracy and Precision
Accuracy - compares measurement with real value
Precision - how carefully and exactly you make your measurement, and the regularity of obtaining the same result
If scientific results are both accurate and precise, they are considered to be valid and true, and is therefore reliable.
When we did our experiments with the m&ms. We realized that we were not being very precise, our results were not reliable. We changed the way we conducted the experiments to make our measurements more precise, which meant our tests were more reliable.
Different situations call for the amount of precision required. If you asked me how long it takes me to drive to Melbourne, I would say 1/2 an hour (even if it only takes me 26 minutes) we round time up and down, because we know that the person asking that question doesn't need such a precise answer. If you asked an runner what their quickest time is to to run 10km, they would give you a more precise time, they might say 43 minutes and 24.7 seconds. Both answers are accurate, but the precision depends upon the amount of information required.
If I asked you how long your desk is, you might say 1.5 m, 152cm, or 1523mm. All are accurate, but one is more precise. Which one would be the answer you would give? Our precision depends on who requires the information, or why they require the information. The smaller the measurement unit, the greater the precision.
If I'm an archer and hit the target in the bullseye I have been accurate. If I continue to hit the target in the bullseye, I will be showing precision. If I don't continue to hit the bullseye, I have been accurate with one shot, but not precise. If I keep hitting the tree next to the target, I am being precise, but not accurate.
Confusing huh?

To summarize:
The precision of a measurement is the size of the unit you use to make a measurement. The smaller the unit, the more precise the measurement.
The accuracy of a measurement is the difference between your measurement and the accepted correct answer. The bigger the difference, the less accurate your measurement

Metamorphosis
WOW! I am so amazed at how a caterpillar turns into a butterfly! The caterpillar goes through such a complete and amazing transformation. It has new eyes, new digestive system, new legs - pretty much everything is new and nothing is left of the caterpillar!
A caterpillar changing into a butterfly (metamorphosis) is an example of chemical change. It is irreversible.
The caterpillar that becomes the monarch butterfly is about 2mm long when it hatches from its egg. In the following two weeks, it increases it's "birth" weight by 3000 times. Which is like an 8lb baby growing to 10 tonnes in two weeks (that's the weight of about 5 cars!!!) No wonder it needs to shed its skin three or four times in such a short time.

Science Experiment
Today we experimented with various ingredients that we have in our kitchens.
1. Lemon juice and water. We found that it created a homogeneous mixture.
2. Lemon juice, water, and oil. We found that it created a heterogeneous mixture.
3. Milk and chocolate topping. We found that it created a homogeneous mixture.
4. Milk, chocolate topping, and lemon juice. We found that a chemical reaction occurred because a new material was formed (gas - which we could see because of the bubbles) and that it no longer looks like the original materials as the properties changed.
6. Bicarb Soda and vinegar. We found that a chemical reaction occurred because a new material was formed (gas - which we could see because of the bubbles) and that it no longer looks like the original materials as the properties changed.

Fly to Mars
Just as a recap on last term's topic, here's a game on Game Up that you can have a look at.
What's the matter with matter?
Game up on Brainpop - Matter Sorter
Sort Matter into Solid, Liquid, Gas, or Plasma? Are you surprised by some of the answers?

Help with your Space Project
Your project should consist of 6 paragraphs (one for the introduction, four for the main body, and one for your conclusion) as well as a bibliography.
You can choose to present this as a formal written report, a slideshow presentation, or a poster.
For more information on how to write an information report, and what I expect, please click here.

Build a Solar System
In this game, players can build their own solar system, trying to find a perfect balance, or creating a system unlike any we’ve ever seen!
Have fun, and try not to blow up any planets! ;-)

2012
Welcome to 2012! I'm looking forward to a year full of fun and learning.
This term in Science we will be learning about Space. Here are a couple of websites that you might find useful to look at:
Scale of the Universe 2
Click on the items on the page for more information about them
(if the above link doesn't work try this one, it's not as good, but gives most of the same information: Scale of the Universe )
Planet Information
Fact Monster - Planets
Let's Explore the Planets
Universe Today
Solar System Tour
