In this exciting STEM activity, you will be given a variety of objects made from different materials. You will weigh each object and then measure its volume by immersing it in water. You will then use this information to calculate the density of each object. Activity to discover mass, volume and density This activity could be used as a main lesson to teach learners how to collect data through measurement and use number skills in a practical context. It could also be used as one of several activities within a wider scheme of learning, focusing on using maths and science to understand the properties of materials. How do you calculate density? Density = Mass / Volume What is the James Webb Space Telescope? The James Webb Space Telescope (JWST) is the largest and most powerful telescope ever to be launched into space. It is a monumental leap in space exploration, building on the legacy of the Hubble Space Telescope. The JWST is the next great space science observatory, with a primary mission to unravel the mysteries of the universe. It will address lingering questions and achieve groundbreaking revelations across all fields of astronomy. The JWST is equipped with a suite of cutting-edge instruments that will allow it to study the universe in unprecedented detail. These instruments will help us better understand the Solar System, the formation of stars and planets, and the evolution of galaxies. The JWST is a revolutionary telescope that will blaze new trails in exploration. It is already making headlines with its first images, and it is sure to continue to amaze us for years to come. Suggested learning outcomes By the end of this activity, students will be able to compare materials based on their density, and they will be able to measure the volume of water and the weight of an object. Students will also learn how to calculate density, and they will be able to communicate measurements using appropriate SI units. The engineering context Space Engineers must have a good understanding of density when they load cargo onto a spacecraft. They need to know the density of the materials they are loading to ensure the rockets have enough power to allow the spacecraft to lift off. Download the free activity sheet!

In this fun STEM activity, learners will make an erupting volcano science experiment using sodium bicarbonate and vinegar. This activity can be used as a main lesson activity to teach learners about chemical reactions, which are processes that change one or more substances into different substances. This science experiment can also explain foams, which are liquids or solids containing gas bubbles. Activity: Erupting volcano experiment This activity is one of a set of free STEM resources designed to help learners use seasonal themes to support the delivery of key topics in Design and Technology, Science, and Mathematics (STEM). This resource is part of a group for the Summer and can be used in school or at home. It involves making a model of an erupting volcano using baking soda and vinegar. When sodium bicarbonate and vinegar are mixed, they react to produce carbon dioxide gas. This gas is what causes the foaming mixture and the eventual dissolution of the solid. The new liquid solution that is produced is relatively safe, but it is important to avoid getting it in your eyes or on your clothes. Safety glasses should be worn if required by the school’s risk assessment. The lava produced can be disposed of by washing it down the sink with plenty of water. How long will this activity take to complete? This activity will take about 40-65 minutes to complete. Teachers can download the activity sheet below for a detailed lesson plan. Those completing the activity at home can download the family activity for a step-by-step guide on making an erupting volcano at home. The engineering context Engineers use chemical reactions to solve a variety of problems. For example, rocket engineers mix fuel and oxidiser to create a reaction that produces thrust, propelling the rocket into space. Suggested learning outcomes By the end of this activity, students will be able to make an erupting volcano using bicarbonate and vinegar, and they will understand that a reaction is when one or more substances are changed to a different substance.

In this fun activity for KS2, students will make balloon race cars from plastic construction blocks, such as LEGO®. Using balloons to power their vehicles, they will measure their speed over a set distance. This activity can be used as a main lesson activity to introduce students to the forces that cause movement or pneumatics. Activity: Build a LEGO balloon race car This resource is part of a set designed to help learners develop their knowledge and skills in Design & Technology, Engineering, Science, and Mathematics (STEM) using summer themes. This resource can be used in school or at home and involves building balloon-powered cars from plastic construction blocks. When making their balloon race car, students can be encouraged to use as many wheels as they want (3, 4, 6, or 8 have all been used effectively). They can also add any additional features they want for creativity, but keep in mind that these may slow the vehicle down. This activity could be carried out individually; however, the speed measurement should ideally be carried out in pairs or small groups. How long will this activity take to complete? This activity will take about 40-60 minutes to complete. The engineering context Space rockets and jet engines use the force of gas expelled from the vehicle to move it. This is called thrust. The faster the gas is expelled, the greater the thrust, and the faster the vehicle will move. Calculating the speed is important for almost all powered vehicles, from family cars to Formula 1 racers to space rockets. The speed of a vehicle determines how much thrust is required to move it and how long it will take to reach its destination. Suggested learning outcomes By the end of this activity, students will be able to build a moving car using plastic construction blocks, they will be able to accurately measure the time taken by an activity, and they will have learned a simple way to calculate speed.

**In this engaging activity learners will have fun with science by making invisible ink from lemon juice mixed with water. ** Learners will then have the opportunity to write secret messages to their friends. Finally, they will use heat to reveal the messages. This is one of a set of free STEM resources developed to support the teaching of the primary national curriculum. They are designed to support the delivery of key topics within Mathematics and Design and Technology. This resource can be carried out either in school or at home. This activity could be used as a main lesson activity, to teach learners about how substances can change colour when heated. How long will this activity take? This activity will take approximately 40-60 minutes to complete. Tools/resources required Lemons of bottle of lemon juice Water Small bowls Cotton buds/paint brushes White paper Hairdryer or lamp The engineering context Engineers are able to use colour changing chemicals to show that something is present. For example, bioengineers working with soil use litmus paper to see if the soil is acidic. Blue litmus paper turns red when it is placed in acidic soil. Materials engineers have created smart materials that can change their properties – for example, thermochromic pigment is used in food packaging to change colour when the food is heated to the correct temperature. Suggested learning outcomes By the end of this activity students will know that some substances change colour when heated, they will be able to make invisible ink from lemon juice and they will be able to write secret messages.
