Engineering Week

This week was Engineering week. We learned about different types of Engineers. There are lots of different types. We had an engineering circuit to learn about different types of engineering. WE made cars   and vehicles and used gears like mechanical engineers, we made bridges like civil engineers and put together limbs and figures like Biomedical engineers. IN science we built circuits and used switches and motors like electronic engineers. Click below to see some pictures.

My reaction time

To test the speed of your reaction get a friend to hold the top of the reaction  strip; place your thumb and first finger so that they are level with the 0.00 line. Your friend drops the strip and you try to catch it as quickly as possible between your thumb and first finger. Read your reaction speed in seconds from the scale on the strip.

Lighthouses

We glued the paper onto pringles tubes and painted them to look like lighthouse.

We made electric circuits using a battery, wires, bulb and bulb-holder. We arranged the circuit so that the bulb was at the top of the
tube and the battery at the bottom.  We put plastic glasses over the bulb.

Design a bridge

1) We made bridges using books and one piece of paper and tested its strength with toy cars.

2) We then made bridges with one piece of paper and folded up sides, i.e. a walled bridge

3) Finally we made bridges with an arch (using two pieces of paper).

The arched bridges were the strongest.

Biodiversity with Dale!

Today we welcomed an Australian  guest speaker called Dale, into our classroom to speak to us about bees, birds, bats, beetles and bugs. We even got to look at some beetles from inside a special container.  Some of us were brave enough to hold an Australian stick insect.

We explored the relationship between various creatures  who live in our environment and learned that there is a purpose for every creature in the food chain.

This “biodiversity” is essential in keeping the environment healthy and fit for human life.

Here are some pictures of Dale’s visit!

Bio-Diversity Workshop with Dale

We had a visitor called Dale this morning and he told us all about bugs, beetles, butterflies, bats, bees and birds.  He had pictures of animals from different countries, like snakes, wallabies, wombats and echidnas (which are like hedgehogs and have babies called puggles.)

He read us a story about Robby Robin. We got to hold a stick insect on our hands. He passed around bug viewers where we got to see a tarantula, a beetle, a cockroach, a spider and a larva.

He played a song called “Bats, Bats, Bats.” Dale is from Australia and when he was in high school his teachers had to go around their football pitches to remove poisonous snakes before they could play the match! He had a special animal caller that looked like a bird’s feather on a long string and when he swung it around really fast, it made a sound like a motorbike.

He also had a bat caller, and he showed a recording of bats flying in his garden so we could hear what they sound like.

Thank you, Dale, for coming to our school!

Science Week – Bouncy Egg

On Monday we put an egg into a jar of vinegar. Today, when we took it out, the shell had been eroded away! Vinegar is an acid and the egg shell is made of calcium. The egg’s membrane remained and this made the egg feel rubbery! We were able to bounce the egg on the table!                                                                                DSC_0340 DSC_0341

Testing our senses!

We explored the power of our senses during this experiment in Science. We held a piece of cotton wool, covered in vanilla essence up to our nose, while eating a piece of apple. The result was that the strong smell of vanilla essence over powered our sense of taste and the apple tasted of vanilla!!

We also identified the different parts of the tongue and got to taste things that were sweet, salty, sour and bitter. We tasted Tuc crackers (salty), fizzy sweets (sour) and lemon and lime (bitter).
