STEM Unit: Simple Machines

STEM is the shortened term for Science, Technology, Engineering and Mathematics. It is a term widely used and taught from es of 5 to college standard. The article is all about developing and building straw structures.

Scientific Concepts


This is a material used to build straw structures. The elements are those that are easy to get, such as drinking straws or gum and tape joining the straws together at the joints.

Material Science

The straw structures with building materials are built up of material and substances easy to manipulate and change. These are such as plastic that you can bend with ease when exposed to heat and this is how the joints will hold together.

Structures and Efficiency

The straw structure building should be enough to stand on its own, but when building a straw structures maybe it would be useful to make the base 5 sided. With a Penton base it is sturdy and hard to force out of shape.

Problem Solving

Straw structure building will equip you with problems solving solutions. The best move is to consider building a sturdy rough sculpture. There are two possible effects on this creation that could be harmful.

Friction – this is a resistance that when two things are rubbed together a heat and energy are created, so when your straw structure encounters friction, it could over heat. To add less dryness, try adding oil.

Gravity – this is the force that brings objects back down to earth. For example, you throw a sock up in the air and when the kinetic energy has been taken over by the force of gravity it will come back down. When building straw structures, gravity can be a problem and the best way to problem solve is to prevent the structure from collapse. You can make the base larger to fight the effect of gravity and exchange the weight of the object of where it concentrates.

Technology Concepts

Safety – STEM projects will aim to equip you with high standard skills and knowledge that are useful in an engineering based work force. During the time of a straw structures build, safety measures like wearing gloves and sometimes masks are called upon. This is to prevent the occasional risk of burns.

Construction Techniques – building these construction methods and buildings such as towers and bridges to name two, the project you gain strength in will be valuable to you should you want to consider this as a career path.

3D Modelling – this is the way of showing constructive structure in the real world. Some projects, such as windmill building expose you to a 3D straw structure use and demo of building these kinds of useful machines and tools.

Designing Process – to design a ste straw structure, the design determines your success. The experience of offering STEM projects will help you in creating civilised structures and through other objects of design.

History Perspectives – these types of projects build and catapult a creation of what is first constructed in history such as going back to the American revolution. The target exposed to an added exchange of career parts into war weapons.

Scale and Structure – engineering has always been a way for engineers to build small projects. The model construction appears to determine if the material are correct and the structure is safe.

Modelling – a model is the presentation of a model set on a particular idea. To enge STEM scientific projects it helps if you have a knowledge that builds on self learnt experience. The broad ways to approach explain to the onlookers of what they do not understand.

Technical Design – the concept is used in order to make engineering for engineers in a way that is un harmful to their crop for example without flooding. When thinking about taking these projects on you need to think of the technically advanced.

Structural Engineering – building straw structure is similar to what technical engineers do. They create a shape and building of the form seen around you. They do the same project to show what is around you.

Observations – when building straw structure inspections are made on routine. It is to take notice of if the structure will buckle under weight. Both weight and structure should be examined before structure is made. When wanting a career in engineering STEM gives you a look into what it involves when developing such construction as bridges.

Analysis – analysis is the routine of breaking down information into maneable pieces. When taking on building straw structures, you will receive instruction on how to use them. Before you begin you must break down all information ready to begin and understand. Once the data is understood the building can start safely and promptly.

Mathematical Concepts

Measures – getting the measurement correct is the only way to end with a satisfactory performance and end result. The straws used are measured as equal. This prepares for real life construction.

Interpretation of Data – information science is important. It is the ability to size up and interpret data that is essential. You will gather knowledge on how the skills are used as a data entry expert.

Number System – this is the route to dealing with numbers fractions and decimal points. It prepares you to take maths at a higher grade.

Life Skills and Critical Thinking

Designing and Technology – STEM projects are better placed with the designer as they will know the route to designing details.

Critical Thinking – the main reason you should never miss taking part in the STEM projects is that it helps you form a better judgment mathematically. You will gain experience in solving puzzles to a high level and standard of mathematical error and judgement.


So to conclude, the concepts in the article above show you why STEM projects are a good idea and what they are. It takes you through what you may or may not have already known and lists reasoning. These projects form the basis of a program of work you can dedicate your life and career too.
