Today we experimented with friction! We used a range of materials (wood, tea-towel, silk and a cushion) to test out the question, ‘How does the texture of a surface affect the amount of friction?’ We used a ramp and a car and covered the ramp with different textures. We found out that the rougher the surface, the more friction. The smoother the surface, the less friction.
During our case study 2 learning, we have been learning all about gravity and friction.
We first of all watched a video introducing gravity, and we also read an informational text about Sir Issac Newton – the scientist who created the gravity law. We were then given the task to use newton metres to measure the weight and mass of objects in class.
Once our learning was secure, we moved onto delving deeper into friction. In order to do, this we carried out a class investigation, we made a hypothesis: the smoother the surface the less friction so the object will move quicker. We concluded this was in fact correct and we were shocked to realise the affects of friction on our world.
To begin part one of our lesson on friction, we recapped some of our prior knowledge and looked at the scientific vocabulary that we needed for the lesson. We then looked at what friction is and watched a video that detailed what life would be like without friction. Once we’d had some more knowledge of friction, we began part two of our lesson which focused on an investigation in which we looked at the effects of friction on a toy car. Before we began our investigation, we discussed as a crew what we thought might happen and came up with a crew hypothesis. We then conducted the experiment to see if our hypothesis would be correct. We used a wooden ramp and 4 different materials to test how far the car would travel on the different surfaces. We were happy to conclude that our hypothesis was correct! We found out that a rougher surface would produce more friction, meaning the car would travel a shorter distance and that with a smoother surface it would travel further as there is less friction.
We have now began our Case Study 2 – physics! We first of all, we watched a video introducing gravity, and we also read an informational text about Sir Issac Newton – the scientist who created the gravity law. We were then given the task to use newton metres to measure the weight of objects in class. We really loved this practical activity to kick start our physics.
We each created a table to recorded our findings:
This week, we kick started Case Study 2, physics, by looking at the force of gravity. We discussed what a force was and identified that most of the crew already knew that gravity was the reason why we ‘stick to the floor’ and do not float. We then built up our background knowledge by watching a few videos that provided more information on gravity. Each time we watched a new video, we added extra information to our chotting sheet, changing colour each time. We then read a text on Isaac Newton, the scientist that discovered gravity when an apple fell down from a tree, and added even more information.
Once we had our background knowledge secure, we looked at Newton Metres which are used to measure the effect of gravity on an object. We had a go at measuring objects from around the classroom which we really enjoyed. We then worked in mini crews to use what we knew about gravity to create marble runs! We knew that gravity would bring the marble down to the floor so came up with some creative ways of making the marble move.
Last week, we applied all what we had learnt in physics to help partly answer our guiding question and reflect on the case study. Great understanding was shown as well as beautiful books that look Y6 standard!
After completing our science touchdown, we needed to consolidate some gaps in our learning so in challenge crew this morning we completed a Kahoot quiz. We worked together in submarine mode to consolidate learning and repeatedly answered questions to ensure our knowledge stuck. Great effort Crew Mcloughlin!
In expedition, we focused on the phases of the moon. We discussed what the moon looks like and how sometimes it can look different; it is always a spherical shape but doesn’t always appear this shape in the sky. More importantly we delved deeper to find out why…
It turns out that we can only see the moon thanks to the biggest light source of them all – the sun!
We looked at the names of the eight moon phases and then the children had an INCREDIBLE time creating the moon phases using OREOS! It was great seeing children working together, delicately picking apart the biscuits in order to accurately show the eight phases of the moon.
If only every science lesson involved Oreos…
Yesterday, Crew Hamill completed a Padlet in which each child added their own statements to each section, detailing the information they could remember from everything we have learned during our first science case study. Miss Hamill was impressed with just how much we’d remembered!
Today in mini crews, we created the phases of the moon using Oreos cookies. Crew Elmer had so much fun.
To continue Case Study 1, we have looked in more detail at the Moon and how it orbits Earth. We learned that the Moon is 239,000 miles away from Earth and that it takes just over 27 days to orbit the Earth. Did you know that we only ever see one side of the Moon? Amazingly, we learned that the Moon doesn’t actual have it’s own light and that we only see it because the light from the Sun reflects off the surface of the Moon. As the Earth orbits our planet, the amount of the Moon we can see differs and this splits into eight phases – New Moon, Waning Gibbous, Waning Quarter, Waning Crescent, Full Moon, Waxing Gibbous, Waxing Quarter and Waxing Crescent. We learned that when the Moon is in the ‘Waxing’ phase, the amount of the Moon we see gets bigger and when it is in its ‘Waning’ phase, we see less of the Moon. We then worked in mini crews to recreate the phases of the Moon using Oreos! We even got to eat them afterwards!
