Building a Bridge

Building a Bridge

Problem:

The problem was to construct a strong bridge that can hold 2 Duct tape for 1 minute.

Materials:

• 10 straws
• 2 A4 paper
• 1 Pipe Cleaner
• 1 cardboard roll
• 1 meter tape
• 1 meter string
• 1 Scissor
• 1 meter ruler

   Procedure:

1.We measured the cardboard roll.

2.We then cut it and placed it around 1 A4 paper (base).

3.After that, we taped the cardboard rolls onto the A4 paper which is the base of the bridge.

4.We folded the second A4 paper horizontally at the  ends of the paper to make the rails.

5.Then we connected 2 straws together for the rails. We did this two times.

6.We taped the rails on the both folded ends of the other A4 paper.

7.Then we got a straw and stuck it horizontally in the middle of the rails.

8. We attached a string that came down from the horizontal straws and the rails.

9. After we attached the string, we stuck some straws on the folds of the paper so it can support the span.

10. Then we stuck the paper onto the cardboard rolls.

11. We then tested our bridge by placing the 2 Duct tape on it. We timed it for 1 minute and it survived. It went a little over a minute.  

Conclusion:

We conclude that in order for our bridge to be strong and sturdy, it needs a lot of support on the top and on the bottom. When there is pressure on the top, it helps make the bridge stronger.

Water Clock Experiment

Water Clock Experiment:

Problem:

How much water drips in 15 minutes

Materials:

• Plastic cup
• Beaker/Measuring cup (not to big)
• Pin
• Water

What did we do?

1. We poked a small hole at the bottom of the plastic cup and then we placed the plastic cup in the beaker.
2. Then we poured some water into the plastic cup and we started the 15 minute timer.
3. We waited for 15 minutes.
4. When the timer was done we quickly took the plastic cup and blocked the small hole so that no water could get out. We then tipped out the extra water that was inside the plastic cup and measured the water inside the beaker.
5. Then we repeated it again until we knew for sure our measurements were accurate.

Observation:

1st attempt:

The water was dripping very slowly and it would sometimes stop. We would have to shake and move the cup whenever the water would stop dripping. For the first trial, the results for 15 minutes was 30mls.

2nd Attempt:

The water dripped faster than the first attempt and we squeezed the cup whenever it stopped dripping. We also got a higher result which was 45ml. We didn’t do 30 minutes but we estimated that it should’ve been around 80 ml.

3rd attempt:

We didn’t get to do the third attempt.

Conclusion:

We conclude that our results differ from one another because in our second attempt we loosened the plastic cup . This could be the cause why the water dripped faster than the first attempt.

A Fossil Discovery

Paleontologists long suspected that hippos evolved from a family of ancient plant-eating partly aquatic mammals. They couldn't confirm it because the old fossils have been discovered 15 million years ago.

The jaw that they stumbled on led them to investigate if they can find remains of an ancient animal. Their curiosity.  Finding the teeth was helpful because the molar patterns on it, is unique. It gives a connection to ancient animals to modern-day animals that we usually see.

The ancient hippo weighed 220 pounds though the modern-day hippos weigh 4,000 pounds. Scientists believe or have a theory that the ancient hippos are related to whales because they spent most of their time in the water. Lihoreau says that hippos are the real African mammal because the animals you see on safaris (lions, zebras, antelopes etc.) were brought to Africa from Asia. Hippos were naturally living in Africa before lions and zebras were brought there.  

Respect Collage

We are learning about respect towards ourselves and others. 

Respect

Evaluating my learning

What did I learn in digital learning?

I learnt how to use different applications to make my published work more interesting and creative. I also learnt how to post things in my blog and how to comment on people’s blogs.

Who helped me in my learning?

I was either helped by a buddy or a teacher. If I didn’t know what to do on a particular application, my teacher would come and help me. Sometimes I don’t understand the strategy that we have to use at math and that’s when a buddy would come and help me, explaining the strategy step by step and making sure I understand. At other times, I would share my work to some of my classmates to check it. The teacher would tell us if we could post our work on our blog .

How is that going to help you?

Applications, such as ‘Toondoo’ helps me in my learning because it helps me learn how to summarise my story into 4 parts. Chromebooks helps me in my learning because the applications that we use on the chromebook help like ‘skoolbo’. Skoolbo is an educational site that helps you learn your grammar, strategies, vocabulary, sentence construction, spelling and tenses.

What am I pleased with?

I am pleased with my blog because last year, I was able to post 74 of my published work. I am also pleased about my mindmeister brainstorm because I was able to think of lots of ideas on a topic.

What did I enjoy?

I enjoyed using Animoto, Toondoo, Mindmeister etc. because they all helped me learn how to summarise my thoughts. Stupeflix was also really fun because we got to look for photos from one of our book reviews. I liked choosing the song, effects and photos that would match the book review. Stupeflix makes my book review (Chinese Cinderella) like a movie trailer. I also enjoyed using my chromebook. The thing about the chromebook I liked was learning how to use Google Docs and Google Drawing.

Mummies

Research: Mummies

Why are mummies organs taken out?

Egyptians took out organs of mummies because they said the mummies ‘weighed’. They didn’t really know much about brains so they used a hook to get it out because they thought it was a waste of space in the head. The brain was the only organ they took out through the nose. The heart was the only organ that was left in the body. They left the heart because they thought it was the centre of thought and intelligence. Once they took out all the organs they would put all of them inside a mini coffin and then place the mini coffin inside the mummy’s coffin.

Why did Egyptians wrap mummies in linen?

They wrapped the mummies in linen because it was part of the process of mummification and because it helped preserve the body for decades. Egyptians believed that you couldn’t go to the afterlife without a body so that is why they preserved the body. Preserving the body wasn’t the only reason why they used linen cloth to wrap the body, they also used it to keep treasures to protect the body from evil spirits.

Did the Egyptians use ointments in the process of mummification?

Yes they did. They did this because it was a religious tradition in the ancient times. They did this because it was the ending of embalming and the beginning of wrapping.

Is it only Pharaohs that are mummified?

No. Mummification wasn’t only for Pharaohs, they were for a class of people like the royal class, the elite class and the middle class. The classes lower than those were not mummified.

When did mummification stop?

Mummification stopped in around the 4th century A.D.

Volcanoes- Q & A

What are volcanoes?

A volcano is a mountain that has a hole on the top. Under the volcano there is an opening to a little pool of melted rock/molten rock which is under the surface of the earth. When a volcano erupts that is when it builds pressure.

How are volcanoes formed?

Volcanoes form when the earth’s upper mantle makes it’s way to the earth’s surface. When it reaches the surface, it erupts and forms lava flows and ash deposits. When it keeps on erupting, the volcano gets bigger and bigger.

Different types of volcanoes:

-Composite Volcanoes

Composite volcanoes are volcanoes that have cinders and a lava flow. Lava flows aren’t spread everywhere in the volcano. The lava flows aren’t big but it is also goes through the middle of the volcano.

-Cinder Cone Volcano:

Cinder Cone VOlcanoes are volcanoes that don’t have lava flows but they still have cinders. The name really gives it away.

-Shield Volcano:

Shield Volcanoes are volcanoes that have no cinders, Only lots of lava flows. These lava flows are like the Composite Volcanoes but Shield Volcanoes have more lava flows.

What destruction do volcanoes cause?

Volcanoes cause very bad damage to structures, buildings, wildlife, the atmosphere, human beings and many more things. Volcanoes can spit out lots of burning ashes. When the ashes land on something that would be most likely to break.

Place/Countries where there are volcanoes:

Countries with the most volcanoes(with the volcano’s name):

Indonesia-147 volcanoes and 76 active volcanoes.

What are Conductors and What are Insulators?

What are conductors?

Conductors are things that electricity can flow through easily. Conductors are made of atoms. The atoms’ electrons move around freely. Some types of Conductors are Copper, Aluminum, Platinum, Gold, Silver, Water, People, Animals and trees. All of these things are great conductors.

What are Insulators?

Insulators are the opposite of Conductors. The atoms’ electrons can’t move freely like Conductors. Insulators aren't that stable which blocks the flow of electricity. Glass, Porcelain, Plastic and Rubber are excellent insulators.
