2 23rd June: STEM DAY Plan Period STEM Activity 1 Science Students meet in under the COLA after roll call Student go to hall where they will listen to presentation by Air force personnel or context and receive sheets Students to identify aim, predicating outcomes, Identifying variables and collect materials 2 Maths Students to take materials to math Maths to look at measuring area and enlargement ratio. Students to cut out shapes from materials 3 Maths Technology Continue to cut out materials Students to take materials to technology, test initial designs and suggest modifications 4 Engineering Students to make three parachute designs 5 Science Students to test and record data from each of the three designs Students to work out the average and choose best parachute to compete in the heats 6 Contest Presentation Students compete with parachute in set heats Winners presented with award

3 Parachute Context: On the 10th of June 2017, a meteor struck the earth with such force that is destroyed much of civilisation as we know it. The few survivors are stranded remote island, away from immediate but too far from life saving supplies. Your mission, should you choose to accept it... Is to create a working parachute design that will safely deliver necessary supplies to the survivors on these Islands. The Big Question is: What shape is most suited to safely land supplies t0 a remote settlement? At the end of the day you and your group will be expected to compete in a parachute drop competition where the slowest parachute will win.

5 S is for Science Question: What shape is most suited to safely land supplies Predict which type if parachute you think will give you the slowest time? (i.e. the longest to land) AIM: Ito Identify the best parachute shape to land a water balloon safely. Independent Variable Dependant Variable Controlled variable Shape of the Parachute Time taken for parachute to land Area of the parachute Mass of the package Height of Drop Equipment List 148 X 75 cm of material ( subject to change) 3 m String - Compass Water Balloons filled with water - Ruler Tape - Scissors - Paper - Pencils -

6 M is for Mathematics Question: What shape is most suited to safely land supplies to a remote settlement? You will need to construct 3 parachute shapes from 1 piece of material. These parachute design must be Different shapes Must be the same area in size You will need to work out the enlargement factor and record the result below Hint: Template size X Enlargement Factor = Actual Size Template size (cm) Actual Size (cm) Enlargement Factor Shape Measurements Template Size (cm) Actual Size (cm) r b h l w

7 T is for Technology E is for Engineering Now that you have your information from both the science and technology parts, you need to start constructing your design. By now you should 3 different shapes in order to construct your parachute. During the next 2 periods you will need to make and test your designs, Criteria: You need to make your 3 parachutes inflate effectively TEST > Record happened Modifications ( what can we do to make it inflate?) Design 1 Does it work? (tick) Design 2 Design 3

8 S is for Science At this stage, you should have 3 working, differently shaped parachutes. The aim of this session is to write a method to test which parachute you will enter in the competition Method Results Parachute

9 Reflection Using the table below, reflect on your process in the development of your final design S T E M Explain how you ensured the reliability of your experiment Explain how to ensured the viability or your experiment Explain how modifications and construction impacted on the success of your overall design Explain how the use of mathematical formula calculated the optimum area of your parachute shapes
