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.

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.

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!

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!

To kick start Case Study 1, we looked at the movement of Earth in relation to the Sun and Moon. We did a lot of research by watching and interactive video that gave us quiz questions throughout, testing that we were paying attention and taking in all of the facts. We then came together as a crew to make a video that detailed everything we learned. Our main facts were:

• The Earth moves in two different ways: 1. It rotates on its axis. 2. It orbits around the Sun.
• It takes the Earth 24 hours (1 day) to rotate fully on its axis.
• It takes the Earth 365 and a quarter days (1 year) to orbit the Sun. 
• When we are facing towards the sun, we get day time.
• When we are facing away from the sun, we get night time. 
• The Sun appears to move across the sky but it doesn’t. 
• The Sun stays where it is and Earth’s rotation makes it disappear.
