Week 3 Science Inquiry Forces TASK 1 Look

Week 3 Science Inquiry Forces

TASK 1 Look at the images on the next slide. Study them carefully – they are all things that can ‘fly’ or move through the air. What do you notice about them? Think particularly about the size and shape of each item and whether it has any specific design features that help it to fly. There is space to write on the slide 4.

Things that can move through air…. .

TASK 1 - My observations on flight: Size Shape Design features

There are FOUR forces that act on something in flight. They are weight, lift (upward force), drag and thrust. TASK TWO – Watch the video and then write a definition of lift, thrust, drag and weight (gravity). https: //www. youtube. com/watch? v=n 8 Ne. W 6 A-LR 4

TASK 2 – My definitions: lift thrust drag weight

Things that fly, from living things like birds to man-made things like aeroplanes, have adaptations to help enable them to fly and to work against some of the forces they come up against. Here are some key words you will need to know related to these adaptations…… lightweight – something that does not carry much weight / weighs less than average Streamlined – a shape or form that presents little resistance to the flow of air or water rigid (structure) – unable to be bent or forced out of shape

TASK THREE – add the 4 key labels to this aeroplane and draw arrows to show the direction of the force acting on the aeroplane. TASK THREE – pick another thing that flies, draw it and add the labels to this diagram also.

TASK FOUR - Complete the quiz on Google Classroom about the forces of flight to see what you have learned today. Over this week we are going to explore AIR RESISTANCE or DRAG in a lot more detail with some fun activities for you to try out at home. Check back tomorrow for the next challenges.
