Making a small seesaw model is a fun-filled way to introduce children to the concepts of levers and forces. By making simple levers, learners will grasp how the effort applied to a lever affects the load. This hands-on project not only sparks their curiosity but also encourages active learning.
We’ve created this seesaw scale activity to support the teaching of key topics within design and technology (D&T), maths, and science as part of the primary national curriculum at key stage 2 (KS2). You can use it as a one-off activity or link it with a measurement activity in food technology.
Activity: Making the lever
Learners will make a simple lever assembly from a binder clip, ruler, two paper cups and sticky tape. Children will also be asked to use a lever to work out the force required to move a load.
Learners will compare results and explain their findings. Depending on available resources, this activity could be carried out individually or in small teams.
Tools/supplies needed:
Rulers
Large binder clips
Paper cups
Sticky tape
Weights such as steel nuts, small weights from science or marbles
The engineering context
Engineers use their understanding of how the effort applied to a lever affects the load in designing a wide range of products. From weighing scales to control pedals in cars, nutcrackers, wheelbarrows, bottle openers, and scissors, levers find their application across various industries. By understanding the seesaw lever class, learners will gain a fundamental insight into the principles that govern these everyday objects.
Suggested learning outcomes
Through this activity, learners will gain the ability to identify the parts of a lever and understand how the effort applied to a lever affects the load. They’ll also understand the principle of balance in a seesaw lever and how distance from the fulcrum impacts the effort needed to move a load. This will equip them with the foundational knowledge about levers, a key component in KS2 science, and provide a practical context for understanding mathematical concepts like multiplication and equality.

How Does the Light from a Torch Change with Distance?
Carry out an experiment to measure how the light from a torch changes with the distance from a lamp
In this activity learners will carry out an experiment to measure how the light from a torch changes with the distance from the lamp. They will record their results in a table and plot a graph.
Activity: How Does the Light from a Torch Change with Distance?
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, design and technology, and maths (in this case, mainly science). This resource focuses on the investigation of how the light from a torch (flashlight) changes with distance.
This activity is designed to be carried out in small groups. It is recommended that the teacher carry out the activity in advance of the lesson, to determine whether the distances suggested give sufficient (or excessive) spread of the light image, as this will be determined by the design of the torch used. It is recommended that new batteries are used in the torch, as the light intensity may be affected by the amount of charge remaining in the batteries.
This could be used as a one-off activity in science or linked to maths learning about tables and graphs.
This activity will take approximately 40-60 minutes to complete.
Tools/resources required
Graph paper
Masking tape
Tape measures
Torches/flashlights (with new batteries)
Pencils
(for extension) laser pointer
(for extension) cut-out templates of simple shapes (e.g. square, triangle, circle), mounted on craft sticks
The engineering context
Engineers need to understand how light behaves when designing products for many practical applications. For example, when designing buildings, they may consider the provision of windows and artificial lighting; and when designing cars, they may consider the power and position of both internal and external lights and the placement of mirrors.
Suggested learning outcomes
By the end of this activity students will be able to carry out a scientific experiment and they will understand that the distribution of light from a torch changes with distance.

Make a Robinson Anemometer
Making a device to measure wind speed
In this science project, students will construct a Robinson Anemometer using common household materials. Once built, students can use it to measure wind speed either inside with domestic items or outside with the natural environment.
This activity can serve as a stand-alone project or as a component of a broader unit on weather or measurement. It is intended for upper Key Stage 2 learners (years 5 and 6).
This resource is part of a collection of free STEM resources created to aid in the teaching of the primary national curriculum, especially in the areas of science and design and technology. The purpose of this activity is to aid in teaching key concepts through the construction of a homemade anemometer.
Parts and components required:
Polystyrene balls, 25 - 40 mm diameter, 1 per anemometer
Wood/bamboo skewers, 3 per anemometer
Putty (such as Blutack or Whitetak) OR modelling clay (such as clay, Plasticine or Playdough).
EITHER 6 paper cups OR 4 paper cups and a plastic water bottle with a sports cap
Sticky tape
Tools and equipment required:
Fans, hair-dryers or other sources of moving air
Stop watches
Commercial anemometer (for extension activity)
The Robinson Anemometer
The Robinson Anemometer is a type of cup anemometer, an instrument used for measuring wind speed. It was invented by John Thomas Romney Robinson in 1846 and is named after him. The Robinson Anemometer consists of four hemispherical cups mounted at the end of horizontal arms, which are attached to a vertical shaft. As the cups rotate due to the force of the wind, the speed of the wind can be calculated based on the rate of rotation. The Robinson Anemometer is still widely used today and is considered one of the most accurate and reliable types of anemometers.
The engineering context
Engineers need to be able to measure the forces that will act on the things they need to design. They need to understand how these measurements are made so that they can be confident that their designs will meet the requirements in practical situations.
Suggested learning outcomes
By the end of this activity students will have an understanding of what is meant by wind, they will be able to construct a simple mechanical device and they will be able to understand that the linear movement of air can be measured by the rotation of an anemometer.

Section drawings
How to Draw a Section Drawing
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 design and technology and maths. This resource focusses on creating a section drawing of a product.
Different types of drawing are used to communicate different types of information. Section drawings are a type of 2D drawing that show the parts or features inside a product. In effect, a section drawing shows the view as if the product has been cut in half – most typically this is along the longer dimension of the product, such as its length. Section drawings are used to show what the inside of a product looks like and how the parts of a product fit together.
Producing a section drawing develops drawing skills, whilst simultaneously allowing concepts such as dimensions, proportion and scale to be introduced in a practical context.
In this activity learners will produce a section drawing of a safety helmet worn by cyclists, working in proportion and ideally to scale.
This could be used as a one-off activity or linked to other D&T activities, such as product analysis or exploded drawing (especially when using the extension activity, creating a section drawing of a pen). It could also be used in conjunction with the IET Faraday Primary Poster – Section Views.
