Do You Know About the Properties of Light?

         

Light passes through some materials better than others. Some materials can be transparent, like a fish bowl.  Other materials that allow some light to pass through are translucent, and then there are some materials where no light passes through. These are opaque.

Why don’t you look around your house and garden and see how many of these materials you have at home?  Test some materials and prove what type of materials they are.

All you need is a torch.

Egg Drop Landers

Have you ever made an Egg Drop Lander? At the 3 /4 level we have extended  our learning on Space by investigating the concept of gravity.  To apply what we have learnt about how objects are pulled into the centre of Earth by the force of Gravity, we have made an Egg Drop Lander.  As part of this project we collaborated with a learning partner in designing and producing the lander.  

Here are some engineers at work.

We will launch and TEST the Egg Lander soon. We wonder if our designs will keep the raw egg safe and land in one piece.

STARLAB’S visit to St Charles

                                                 IMG_1478Starlab  an inflatable dome, came to St Charles last Friday. The 3/4 level was treated to an exciting incursion where we were lucky to see the night sky, constellation graphics, and Earth maps in the Starlab Cosmodome.

We learnt about the size of the Sun which keeps Earth warm and enables all living things to continue living. Did you know that there are other bodies in the universe that are much bigger and larger that the sun? The images below show this.

We also saw images of the constellations. IMG_1503 

Did you also know that August is one of the best months of the year to observe the night sky?  During August we can see some of the planets with the naked eye- that is without telescopes.  During the last week of August you will be able to see Mars, Saturn, and the red star Antares. On August 27 you will be be lucky enough to see both Venus and Jupiter as they come together. this will not occur again until the year 2065. So why not go out and see what you can see in the night sky? Let us know what you observe. 

Science Experiment in 1/2J

As part of our science unit we have been conducting science experiments in 1/2J. This week we have been exploring floating and sinking. We were in groups and we had a container filled with water. We had to predict what items would float and sink. We used a paperclip, a volleyball, a ping pong ball and a bottle top. Then once we finished our prediction and we could start testing and observing what happened. 

Here are some photos of us doing our experiment.

What do you know about the Sun, Moon, Earth System?

In 3/4 we  learning about our amazing universe. these past two weeks we have investigated the Sun, Moon, Earth System. We have made working models of the system where the Earth spins and orbits the Sun, and the Moon orbiting the Earth. 

Paige: The Earth is 100 times smaller than the Sun.

Lucas: The Moon orbits around the Earth, The Earth orbits around the Sun. it takes the Earth a year to orbit around the sun.

Alessia P: the Earth is four times larger than the Sun.

Stephanie: The Earth spins around the sun, while the Moon rotates around the Earth.

Here are some of our working models of the Sun, Moon, Earth System.  What do you know about this important System? Let us know!

HOW DO ANIMALS BREATHE UNDERWATER?

Our lungs are great at getting oxygen out of the air, but if we needed to do that underwater, we’d sink. So how do fish, shrimp, jellyfish and other marine animals breathe underwater? And what happens when there is no oxygen in the water for them to breathe?

3 /4 EXCURSION TO CERES

Last Thursday the 3 /4 level went to CERES, as part of the unit of Inquiry on ‘How can we be water wise?’  the students were involved in various learning experiences centered on living sustainably, using resources, recycling and reusing.  CERES is a community garden where sustainable strategies are practised and where people are welcomed to learn and observe how simple some  conservation practices really are to implement in our homes and gardens.  The students walked along the Merri Creek and saw first hand the effect of regeneration along the creek bed, with many more native trees and bushes growing along its banks. This regeneration is gradually bringing back  bird and aquatic life.  students learnt about effects humans have on the river’s life, how to measure weather and how to save water in the home. A  great day was by all and hopefully we can put some of the leaning into the way we all interact with our environment.

Let’s be Scientists

How can you blow up a balloon using vinegar and bicarb-soda?
Do you know which balloon will hit to the ground first,  one that is blown up with vinegar and bicarb – soda or one blown up the traditional way? 
Have you heard of fireproof balloons?
What effect does heat have on vinegar mixed with bicarb-soda?   
Very interesting questions!
Students in 3/4 had the opportunity to be real scientists by planning, designing, testing, evaluating and presenting the findings to these questions and others. Curiosity and the fun of mixing substances that fizzed, bubbled and overflowed was the norm as students applied higher order thinking skills to demonstrate the scientific method.  
The images below capture the enthusiasm and the imagination of these scientists at work.  Well done to all teams!

1/2’s Super Science Expo!!

“What happens when we….??” has been our fun InquiRE topic this term.  In Science we have been learning about how everyday materials can be physically changed in lots of ways.  Each week we rotated across the 1/2 level and took part in experiments that showed a change.  This week it was now the students turn to research, write up and present an experiment of their choice to the class, all by themselves!!! Everyone had a great time using their new knowledge to explain what changes were happening in their experiment.  Well done to everyone for putting in such hard work and effort to make it such a fabulous Science Expo!!

Crime Scene Investigation and Experiment presentations for Inquiry

Last week the 5/6s were busy presenting their inquiry projects to each other. Some of the crime scene investigations they put together were so tricky that they were hard for us to solve. The chemical science experiments presented were also very impressive, particularly the volcano made for Oliver K for his volcano eruption experiment. All students are growing so much in confidence with their presentation skills :)!

What are Microbes?

As part of the 3/4 level science incursion we designed our own microbes. Do you know what a microbe is? Microbes are living organisms, they are small and we need a microscope to see them. They come in all different sizes and shapes.
They are found everywhere! 
Some microbes are useful and even good for us however some can make us ill.
We drew our own microbe, either a bacterium, a virus or a fungus. Before we started we had to decide if our microbe was to be beneficial or harmful. We had fun naming them. Here are some of our microbes!

Famous Scientists

As part of our science unit this term we have been looking at famous scientist and inventors who have made important contributions to our world. Some of the scientists we have looked at are Albert Einstein, Marie Curie, Thomas Edison, Stephen Hawking, Jane Goodall, Sir Isaac Newton, Ernest Rutherford and Galileo Galilei. 
The students have enjoyed researching their scientist and creating a poster on Google Drawing. Have a look below at some of the posters we created!

Science Incursion #3

Science Incursion #3

The 3/4s enjoyed an incursion with Scientists who study our Immune Systems. We looked at White Blood Cells and Red Blood Cells, which taught us a lot about Bacteria (when we get sick) and how our body works to keep us healthy.

Some students even got to dress up as Scientist!

We also looked at The Scale of the Universe – You might even like to have a look at the Scale yourself at the link below 🙂

The Scale of the Universe

Let’s be Scientists!

The students on the 3/4 level have been busy being scientists this term. We have investigated aspects of heat and how heat is transferred from objects to objects.  The students have investigated the following questions: What is heat? What materials make good conductors? What materials make good insulators? Students investigated materials which kept hot water warm. They investigated materials including, foil, bubble wrap, felt, aluminium, paper and other everyday materials. They concluded that insulators trap the heat and block it from escaping. During the investigation the students periodically measured the temperature of the water in each cup to determine the best insulator.

Science with a zing!!

In Science in 1/2, we have been looking at how everyday materials can be physically changed in a variety of ways (ACSSU211) and that different materials can be combined including by mixing for a particular purpose (ACSSU031). 1/2B used the method below to make their very own lemonade this week, however, we’re not quite sure it’s supermarket ready just yet!!

Making Lemonade
What you’ll need- Lemon, drinking glass, water, baking soda, sugar, straw, teaspoon
Method- Squeeze as much of the juice from the lemon as you can into the glass. Pour in an equal amount of water as lemon juice. Stir in the teaspoon of baking soda. Give the mixture a taste and add in some sugar if you think it needs to be sweeter.

The bubbles that form when you add the baking soda to the lemon mixture are carbon dioxide (CO2); the same bubbles you’ll find in proper fizzy drinks. Of course they add a few other flavoured sweeteners but if you’re wondering how the carbon dioxide bubbles formed, it was because you created a chemical reaction when you added the lemon (an acid) to the baking soda (a base).

Scientists at work!

This week 5/6I have been change detectives! We have observed chemical reactions by mixing, observing, investigating and using scientific knowledge to explain our thinking. Keeping with our Environmental Tree-Planting Day, our leaf art involved learning about photosynthesis and how environmental changes can impact on leaves.

Change Detectives – Chemical Science – 5/6

The 5/6 students have engaged in a ‘Mess Scene’ investigation to find out what they already know about changes that occur to materials in their everyday lives.They observed and recorded information about some common changes to materials and shared and discussed their observations. They questioned why certain changes occur and whether or not they are easily reversible.It sparked the students’ interest, stimulated their curiosity, raised questions for inquiry and elicited their existing beliefs about the topic.

OUR EXCITING INCURSION!!

3/4 SCIENCE INCURSION 

The 3/4 Level had a great day last Friday when Michelle came for an Incursion. She is a scientist from Monash University and also a mum at the school.  The students had a great morning conducting experiments with Dry Ice, Flowers, Detergent and Sugar. Everyone had a collaborative hands on learning experience! We are very lucky to have Michelle!

What Happens When We…?

This term in InquiRE 1/2s are learning to be scientists and asking the question ‘What Happens When We…?’ Our first experiment was mixing coke and mentos together and before we watched it we predicted what we thought might happen when we mixed a liquid and a solid. We were amazed to see the results, a cool ‘explosion’, which we now know is a gas. Can’t wait to put on our lab coats again 🙂
