Before we left we learned about the plants and animals we might find on the seashore, such as seaweed, Marram grass, crabs and rag-worms. We got into pairs and walked to the North Beach past Bremore Castle.

When we got to the beach we worked in pairs to find all the things on our scavenger hunt. We found everything except a buoy. Angell and Logan found a huge Ragworm hole.Then we played football or played in the sand. We had a lot of fun and the weather was really nice.

We ate our lunch at the beach. It was like a picnic. We played a little bit more and investigated some rock pools where we found lots of crabs and fish. Molly found a big green crab. Some of us made sand mermaids from seaweed and shells. Then it was time to go back to school.

We really enjoyed our trip to the beach!

More Sound Experiments

We put cling film over a bowl and then placed some grains of rice on the cling film.  When we banged loudly near the grains of rice we were able to see the rice move. The sound waves made by the loud noise made the gains ‘jump’.

We also made ‘duck whistles’. We cut a straw in half, then cut a ‘v’ shape into the top of the straw. By blowing hard into the straw, the straw vibrated and made a ‘duck’ noise. It was quite hard to make the sound, but it was funny when we did manage it.

Learning about sound

We’ve started  learning about sound. We have learned that sound travels in waves. We also learned that sound is a force, like light and heat.

Our first experiment was with tuning forks and some water! We banged the tuning fork sharply on the table to make it vibrate (and sound) and then we popped the vibrating fork into the jar of water. The vibrations made the water splash out of the jar.

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
