Save the animals! I sea I care marine issues

Guess how many marine animals are endangered right now? There are approximately 2,215 endangered or threatened marine species in the world.

3/4W were sent a task by the I Sea, I care Assignment Desk (that is the 3/4 teachers) to research an issue that is a problem for the marine world. We have started making videos about these issues and came up with 92 solutions altogether to help solve these problems. Here are some of the issues we thought were important:

How might we help the ocean for animals in the daylight zone so that they don’t get hit by ships?

How might we stop global warming for the animals living on the ice so that they can still have ice to live on?

How might we get rid of pollution and rubbish in the sea for the marine animals so they don’t get extinct and die?

How might we stop dolphins/sharks/whales from getting caught in nets so they don’t become endangered?

How might we stop people from littering for the marine animals so that they don’t get sick or die?

How might we stop oil from leaking for the ocean so that animals won’t have a polluted home?

How might we stop people from over hunting for the marine animals so that there will be more animals?

How might we stop global warming for the coral so there will be no more coral bleaching?
3/4W have been trying to help solve marine problems by researching and coming up with solutions. These are some of the solutions we came up with in 10 minutes:

Use solar cars so there is less pollution

Make an alarm to scare animals away from nets

Create a law where no one is to go within 20km of harp seals and whales

Make oil evaporate like what water does

Don’t litter

Create a certain fishing area where dolphins can’t go

Don’t use nets to fish

Invent a spray to spray on ice so it doesn’t melt

Can you think of any other solutions for solving our problems? Or can you think of another important marine issue?

Journey to our fun Philip Island camp

On Monday 17th August three 3/4 classes went to Philip Island for camp. It was a long journey but it was definitely worth it! We  had lots of different experiences such as going to the Penguin Parade, having a movie night, doing different adventure activities, eating a lot of food and many more!

Some things that we especially enjoyed were:

  • Going on the giant swing
  • Having cabin time which might include reading a book or having a rest or talking with friends
  • Having free choice and playing different games
  • Going on the flying fox
  • Doing archery
  • Making pancakes and eating them
  • Eating the delicious food
  • Going on the Nobbie’s board walk and seeing the waves crash and seeing some penguins

What did you like the most at camp and why? Have you ever visited Philip Island and if so, what did you enjoy there?

I sea I care!

This term our integrated unit is called “I sea I care” and it’s about marine life. We watched two videos about the Great Barrier reef and life in the deep ocean. Here are some questions we came up with after watching the videos:

How many sea creatures are in the ocean?
How many sharks are in the ocean?
Why do people catch creatures?
How can spiders live under water?

What would be different if people didn’t fish?
What would change if there were no fish in the ocean?
Why and how do some sea creatures glow in the dark?
If people can go to the moon, why can’t people go to the very bottom of the ocean?
Is it possible for people to make gear to go to the very bottom of the deep ocean
What would change if everyone knew everything about the ocean?
Why do whales only eat plankton? Shouldn’t they eat more than that?

What would happen if we didn’t have coral reefs? As a class, we explored this question and came up with these answers:
Fish wouldn’t have a place to hide or live so sharks/predators could easily get them.
The food chain would be affected. For example bigger fish eat the small fish. So if the small fish were no longer there, the bigger fish would die.

Can you answer any of these questions? Or can you think of another question?

Gould League Excursion

On Friday 12th June, 3/4 classes went to Gould League for an excursion for the whole day. This was a sustainability centre. Some of our highlights included:

  • Seeing worms in the containers. Some were big and some were tiny. We learnt that worms have a saddle and they have babies very quickly, every few weeks.
  • Going to find some mini beasts in the soil. We found centipedes, cockroaches, earwigs, worms and millipedes.
  • Tasting the herbs likes mint, parsley, oregano, Vietnamese mint, curry leaves and rosemary.
  • Going into the shrinking machine. We learnt what is inside a compost bin. Inside a compost bin live worms who make oxygen for the compost. We learnt that spiders in compost bins don’t do anything except wait for flies to eat.
  • Learning that the egg of a worm contains up to 15 worms.
  • Learning that worms have 5 hearts.
  • Learning how long it takes for some materials to decompose.

3/4W’s Awesome Science Experiments

This term, 3/4W have been doing a variety of experiments. At the start of the term we did an experiment with ice to see how long it would take to melt. We then did this experiment again because we found that when we first did it, it was not a fair test.

This is some of our reflections after doing the first ice experiment:

The ice melting experiment number 1

It’s not fair because some people got the ice before others.

It’s not fair because some people got bigger bits or more ice than others.

It’s not fair because some people did different things with the ice like putting it on the finger, the hand or sucking it.

It’s not fair because some people were in the shade and some people were in the sun.

How could we make it a fair test?

Start at the same time by taking the ice at exactly the same time. We will put ice on the table so that everyone can get it at the same time.

Getting ice of the same size.

Making sure people are in the same environment or place or weather.

Everyone put the ice on your palm. If people are putting it on different areas of their body or hand than the ice might melt quicker or slower.

We will have only one person to do the timer and we will use an online stopwatch.

We found out that most ice blocks melted after 9 minutes. However, another class found most of theirs melted after 5 minutes. We think this might be due to the weather.

Something that is difficult to change

Everyone’s hands are different temperatures.

These are some pictures and steps for our other experiments.

Hands on Science

In Term 2, 3/4W had two sessions of Hands on Science. We explored different science activities and learnt about different states of matter including gases, liquids and solids. Some highlights include:

  • Touching balloons with gas, solids and liquids.
  • Doing experiments with liquids. We waved glycerin and purple crystals on top of flame.
  • We learnt what happens when you wave citric acid over a flame.
  • Touching the strange dough like object made out of hair conditioner, baby oil and corn flour.
  • Seeing which melted first out of chocolate and wax. What do you think melted first?
  • Seeing what happens when we leave water and mentholated spirits on a lid.
  • Putting yeast in different jars, all with different temperatures, then putting balloons over the jar and seeing what happened.

Have a look at our photos below.
