In 4E we have been learning about different discoveries and scientist that have impacted our world. We all chose a scientific discovery we were interested in and were able to use keyword searches and paraphrase important information.
We first had to think about the type and amount of information needed for our presentations and created a rubric to assess our work.
“I think a 3 star presentation will include lots of information that explains each idea in detail. It should have at least a page worth of information per paragraph,” Melissa.
“A one star presentation will have very little information and would be less than 1 minute,”Lucas.
Some facts we have learnt while researching are;
“Albert Einstein won a Nobel prize in 1921 for his work in physics,” Lucas.
“Cars were invented in 1985-1986, by Karl Benz,” Haydar.
“Penicillin was discovered in 1928 when Alexander Fleming came back from a break and found a mould that killed bacteria,” Zain and Abaan.
“Galileo discovered that the moon had mountains just like earth,” Melissa.
Today we experimented with the Makyey Makeys. The Makey Makeys is a set which includes alligator clips, a USB to connect to the computer and a circuit board. It allows us to experiment with technology and use materials to make a keyboard.
Here is a link to the website we watched to help us understand how Makey Makey works.
We also learned about inputs and outputs. An input is something that the computer receives and output is the information the computer sends. ‘For example, with the Makey Makeys, the input was the Makey Makey (telling the computer to do a certain thing) and the output was the game’, Zain.
We have been experimenting with different materials to see what would take less tome to melt ice. We had to write a procedure of what we would do in our experiment. We first thought of a hypothesis to predict what we thought would happen when we mixed different materials with ice. We had to think about the materials we would use and the steps we needed to follow in order to be successful with our experiment. While we were experimenting with the materials, we recorded the elapsed time to think about how long the ice took to melt, so could see which material would melt the ice the fastest. While our ice was melting we monitored the chemical reactions that were occurring. We looked at the results of our experiments and used this to reflect on our hypothesis so we could write a conclusion.
The bicarb soda took a very long time to melt the ice. The bigger part of ice stayed solid and the smaller parts started to turn white as it mixed with the bicarb.
In conclusion the bicarb soda did not melt the ice in 40 seconds, instead it took 25 minutes and 9 seconds to melt.
In conclusion the lemon juice and ice took a very long time to melt ice and salt was the quickest to melt the ice.
Today we Skyped a scientist with Mrs Caccianiga’s class and his name was Wesley. We learnt lots of important information about microbial ecology and how microbes can affect our world. Some of the information we learnt is;
‘I learned that there are more good microbes than bad microbes and microbes produce oxygen so we need them to survive,” Charli.
“Microbes can effect our mood, ” Abaan.
“Microbes are in our body. They can be good and bad for us. When we get sick it can be the cause of bad microbes and that is the same as coral reefs but we need them to keep us and the corral reefs alive,” Zain.
“Microbes can be multicoloured and have different patterns on them,” Briana.
“There are more microbes in our body than in the ocean,” Charli
“Scientist can work by themselves or work in a group,” Ava.
Today is better buddies day and we have been doing some fun activities with our grade 1 buddies. Some of the cool activities included making a collage of a face using fruit and vegetables, a lip sync battle and taking pictures of different actions.
‘My favourite part was the collage activity because it was fun to make our faces with our buddies,’ Keisha, Zayd and Reet B.
‘My favourite part was taking photos with our buddies,’ Kanod.
‘I liked working together to take photos of different poses,’ Gisele
Below are some photos of our work and us doing the activities.
Next week we will be Skypinga scientist with 4A to help us with our big idea of ‘Discovery’. To get our thinking and ideas ready we have been watching videos and researching facts about what a microbial ecologist is. While we were researching we recorded questions about microbes and sorted this information into different categories. We then used this knowledge to think of questions we could ask the scientist focusing on microbes and coral reefs. Some interersting information we learnt was;
‘Microbes have lived for over 3.4 billion years,’ Zain.
‘Microbes are extremely small and cannot be seen with the human eye,’ Aadya and Abaan.
‘There are 10 types of microbial cells in the human body and there are over 100 trillion microbes in the human body,’ Charli, Keiana, Ava, Feyza and Anuk.
‘Microbes can cause disease from bacteria which is not good for us but they can also be good for us,’ Marco and Briana.
‘When there are lots of microbes together it is called thrombolite,’ Harjas.
Over the past few days we have also explored the idea of night and day and how timezones affect the different times around the world. This helped us to determine the time it will be when we skype the scientist. We discovered that if we skype our scientist on Tuesday morning it will actually be Monday afternoon for them because they live in Hawaii and their time is different to ours.
This term our big idea is ‘Discovery’ and we have been exploring different provocations to get our ideas and thinking ready. Some of the provocations were around different sciences such as biological, physical, chemical and geological.
For biological there was small pictures with parts of an animal and we were given the challenge to draw the rest of the animal using our knowledge of animals.
For chemical there were many ingredients such as flour, oil, vinegar, bicarb soda and water placed on a table. We had to draw what we thought would happen when we mixed ingredients together and then we got to experiment with the ingredients. There was many different chemical reactions from the mix of ingredients.
For geological we explored different landscapes around the world. This included pictures of mountains, volcanoes, waterfalls and many others. We then had to create a landform using play dough.
For physical we watched different videos which included inventions and heavy objects. We then recorded our questions.
Some of our favourite things were;
“The chemical table because when I mixed things together it made a reaction of rising bubbles, which was like a volcano.” Mohammad
“My favourite was the geological table because it was fun making waterfalls and mountains” Keerit
“My favourite was the biological because we had to think about what animal could the beak belong to and had to draw the rest” Feyza
‘My favourite was the Geological because it was fun to learn about the different landforms on earth and making predictions about the landforms.” Lucas
‘My favourite thing was watching the videos of the Physical Sciences.” Gisele
Every second week we get to work with our buddies which are grade 1’s. This week we played some teamwork games which involved a parachute. Some of the challenges involved working together to get the ball to a certain person. This one was hard because everyone kept shaking the parachute. Another challenge was crawling under the parachute with our buddies which was our favourite because some people got stuck inside and it was funny.
We have been using Bloxels to create a visual picture of the characters in our books. We first read our books and thought about the inside and outside character traits that make up our characters. We even thought about different zones our characters were in at different stages of our text.
We then had the challenge to give each colour we used for our characters a place value of ones, tens, hundreds, thousands and some of us even went higher than ten thousands. Using this we used our renaming skills to record the numbers that make up our characters.
“My character is made up of 17 white cubes and each white cube is worth ten so the value is 170.” Yazel
We then had to add the total numbers of each colour together to work out the total value of our character.
“My character’s value was 12,428,104.” Abaan
We have been writing clues for others to guess the value of our character. See if you can guess the value of our character!
My character is made up of a 4 digit number
My number is an odd number
My character is made up of only odd numbers
My number has 179 tens
My character has a 7 in the hundreds place
My character has a 1 in the thousands place
My character has 2 number 1’s that make up the number
My character has a 1 in the thousands place and the other numbers are in ascending order
