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.

How sounds travel as waves of different frequencies and wavelengths 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 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. 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.

Learn about the robots used to perform remote surgery and the important role of electromagnetism Telemedicine is a new and fast-developing field in healthcare. Even 20 years ago the idea of a surgeon being able to operate a robot from hundreds of miles away in order to perform an operation seemed like science fiction. Today, this is not only possible but engineers, working with scientists and doctors, are now designing robotic systems which will be able to operate on patients with no human intervention at all. This activity is a quick, engaging introduction to a lesson using telemedicine and robotics as a context to explore electromagnetism and the link between technology and real-life science.

Balancing forces to design a boat Using knowledge of forces in an engineering design context The balancing forces to build a boat activity tasks participants to apply scientific and mathematical understanding of forces (resistance, buoyancy and thrust) and Newton’s 3 laws of motion, in an engineering and design context. Relate speed to the streamlining in boat design and the shape of a boat’s hull. Consider the balanced and unbalanced forces the boat needs to withstand for maximum efficiency. This activity will demonstrate the principles of hydrodynamics, a similar set of principles to aerodynamics but involving water. This activity is designed to be taught through science and design and technology simultaneously, as a cross-curricular project. However, it can also be tackled independently from each subject.

A fun engineering challenge for KS3 that will give students the opportunity to test boat hull designs in a test tank. Through this process, students will learn about the importance of applying relevant scientific and mathematical understanding when refining and developing an idea. This activity allows students to explore and develop their critical thinking and decision-making skills through a practical approach. The experiment ensures a ‘fair’ set of results is produced. The success of their overall boat hull design is directly dependent upon how well they apply their knowledge and understanding across the disciplines. In addition, key learning points needs to be reinforced through mathematics. The students could carry out initial research into different hull shapes used for various types of boat, and they should produce an image board of hulls with annotations to explain why the shape of the hull is appropriate for the particular type of boat. Types of boat hulls that could be researched include yachts, cruise ships, speed boats, fishing boats, container ships, and catamarans. This activity is designed to be taught through science and design and technology simultaneously, as a cross-curricular project and ideal for use in a STEM Club. However, it can also be tackled independently from each subject. Tools/resources required Test Tank (the construction is a fairly simple activity and can be undertaken by your KS3 students (as an after school activity) or by a technician) Vacuum Former High Impact Polystyrene/MDF or softwood blocks Optionally, modelling clay General Workshop Facilities Stopwatch Masses with a suitable holder The engineering context The focus of this activity is on the principle of hydrodynamics (a similar set of principles to aerodynamics but involving water). Suggested learning outcomes By the end of this activity students will be able to understand the importance of testing models and prototyping within the development of an idea, the need for streamlining in boat design and the principles of hydrodynamic design. Students will also be able to refine ideas in order to improve outcomes, they will be able to relate the shape of the hull to speed and the forces it needs to withstand maximum efficiency and they will be able to apply scientific and mathematical understanding to an engineering context.
