Time the journeys of different shaped boats and present the results This engaging engineering activity for KS3 considers displaying data from a practical investigation looking at the effect of streamlining a boats hull. Students will be asked to consider how this information can be represented effectively and use this to form conclusions. The reliability of their results will then be discussed. Activity Measuring boat speed Students will use the test rig, which can be found in the resources below, to test several different shaped boats. Students should measure the time taken for each boat to travel a set distance and record the results. Ask the students to discuss the fact that there is no measurable independent variable as it is very difficult to quantify the hull shape in terms of numbers. The students should ponder how they are going to represent these results graphically. If time is available, complete the investigation by repeating the tests. Discuss the sorts of errors that might occur in the collection of results. Learners will then plot their results into a bar graph. This could be used as part of an advertising campaign to sell the boat which could include design, bar chart, a brief conclusion and an explanation as to why the results are reliable. There is also an opportunity to use data logging equipment as well as light gates to further reduce errors in this engineering activity. As an extension, students could calculate speed (s=d/t), and the mean speed for each boat, taking into account the anomalous results. Students could consider what they could measure to draw a line graph and find the optimal hull design. If time is available, students could manufacture and test their own designs and include them within the analysis. This activity will take approximately 45 minutes. Tools/resources required The construction is a fairly simple activity and can be undertaken by your KS3 students (as an after school activity or by a technician) Boat objects Stop Watch Graph Paper Suggested learning outcomes By the end of this activity students will be able to explain when to use a bar chart and when they should be used to display categoric variables, they will be able to evaluate an experiment in terms of its reliability and precision and they will be able to apply scientific and mathematical understanding to an engineering context.

Learn about sound waves in this free STEM with this free lesson plan for KS3 From founding communications, such as the fire beacon, to being able to communicate with space, there is no denying that developments in communication have advanced at a rapid speed. This topic presents students with communications of the past, present and future, helping them to understand the principles that form the basis for these developments. This engaging STEM activity is aimed at KS3 students and deals with how animals use sounds and how sounds change in natural phenomena. This is so that a student can understand how sound waves travel. The teacher will first distribute a copy of the ‘Animal Sounds’ handout, which can be downloaded below, to each student. Make sure students understand sound is a longitudinal wave of compressions and rarefactions of the material. Soundwaves follow the laws of wave behaviour, so they are a useful introduction to wave properties. This activity can be simplified (particularly for less able students) by creating a discussion on why different animals have different hearing ranges and their experience of phenomena such as the Doppler effect. Use the handout to discuss different sounds and what they might have learned in other lessons (e.g. music) about pitch, frequency, amplitude etc. As an extension students could produce a display from low to high frequency, showing where the sound ranges used by different animals lie. Students could consider how sounds outside the normal spectrum could be used to develop new products. For example, to make ‘silent’ devices to broadcast sound or data between two points. This is a quick and simple activity that will take approximately 15 minutes. Tools/resources required Calculators The engineering context Sounds are vibrations travelling through materials. Many animals make sounds, either for communication or for location. Sound travels at different speeds in different materials. Generally, the denser the material, the faster the sound will travel. Sound is a longitudinal wave of compressions and rarefactions of the material (a rarefaction involves particles in the material being more spread out than usual). Sound waves follow the laws of wave behaviour, so they are a useful introduction to wave properties. Suggested learning outcomes By the end of this free resource students will know that sound is produced by objects vibrating and they will understand that sound is a longitudinal wave. They will also know about the range of frequencies that can be heard by humans and other animals and they will understand that sound travels at different speeds in different mediums.

Investigating everyday products to see if they are magnetic In this activity learners will predict whether they think different products are magnetic based on the material that each product is made from. They will then test their theory by using magnets, to see whether or not each product is attracted to a magnet. This resource is a great way for KS2 students to learn all about magnets and could be used as a one-off activity or as part of a wider unit of work focusing on magnets and magnetism. It can also be used in conjunction with the IET Education ‘Magnet Madness’ resource, developed alongside the School of Engineering at Cardiff University. This is one of a set of resources developed to support the teaching of the primary national curriculum. They are designed to support the delivery of key topics within science and design and technology. This resource focuses on identifying whether everyday products are made from magnetic materials. This activity could be completed as individuals, in pairs or in small groups. Learners could be given all the products at once to test, or the teacher may wish to lead through one product at a time, recapping the key tasks and questions for them to consider as they go through. Discussion topics and key questions for learners can be found on the presentation below and detailed instructions on how to complete the activity can be found on the activity sheet. This activity will take approximately 40-60 minutes to complete. Tools/resources required Magnets Plastic drinks cups 2 pence coins Steel door keys Aluminium drinks cans Steel paper clips Wooden toy cars The engineering context Engineers need to know the properties of magnets, which materials are magnetic and which materials are non-magnetic. This knowledge could be used when identifying and creating potential solutions to future engineering problems. Suggested learning outcomes By the end of this exercise students will know which materials are magnetic and which are not, they will be able to give examples of magnetic and non-magnetic materials and they will be able to test products to see whether they are made from magnetic materials.
