The History of Christmas tree ornaments The history of Christmas tree ornaments is a fascinating tale that dates back centuries. Historians trace the tradition of decorating trees during the holiday season to ancient civilisations like the Egyptians, Romans, and Vikings, who adorned trees with symbols of prosperity and religious significance. However, the modern concept of hanging ornaments on Christmas trees emerged in Germany during the 16th century. Initially, these ornaments were simple decorations made from fruits, nuts, and candles. Over time, the ornaments evolved, incorporating glass-blown baubles, delicate figurines, and intricate designs. Today, Christmas tree ornaments are cherished keepsakes, reflecting cultural traditions and personal memories and symbolising festive cheer and celebration.

Try out this fun science experiment, designed for primary school students, to catch Santa as he delivers your presents by creating an electronic trap! The engineering context Engineers need to be able to understand how electrical circuits are drawn and communicated; This includes the use of circuit symbols to produce circuit diagrams and schematics. This knowledge could be used when investigating, designing or making electrical and electronic circuits in the future. What equipment will you need? A thin piece of sponge – a washing up sponge is great, but make sure it is completely dry, Scissors, Masking or sticky tape, Aluminium kitchen foil, 3 crocodile leads (you will need another 2 if you do the extension task), A 2 x AA battery pack, A 3V buzzer How to do it Step 1 - Cut a square of the thin sponge approximately 10cm x 10cm. In the centre, cut a hole approximately 4cm in diameter. ⚠ Be careful when using scissors. Always have an adult on standby in case you need help. Step 2 - Cut two pieces of aluminium foil slightly smaller than your piece of sponge. Step 3 - Using masking or sticky tape, tape one piece of aluminium foil to the top of the sponge and the other to the bottom. The tin foil pieces MUST NOT touch if the sponge is not pressed down but should once it is pressed. Step 4 - Attach one crocodile lead to the top piece of foil and one to the bottom piece. You have now built the pressure pad for your Electronic Santa Detector, but you need to put it in a circuit for something to happen. Follow the diagram in the activity sheet below to connect the components with your crocodile leads. When you gently press the centre, the buzzer should sound. Now all you need to do is leave it somewhere you think Santa will stand when he delivers your presents. Just inside your bedroom door, perhaps, or at the end of your bed with your stocking. When he steps on the pressure pad, the buzzer will sound and alert you to him being in the room. You might also want to disguise it so it is not noticeable. Santa is old and wise, and if he sees it, he will know not to step on it! Download the Make a trap to detect Santa activity sheet for free!

Protect Santa’s packed lunch with this fun insulator experiment This activity can function as a fun science experiment for kids in which students will observe the effects of thermal energy on change of state. What equipment will you need? Ice cubes with a small Christmas toy frozen inside (cake decorations are ideal for this or any small Christmas toy/decoration), 5 different types of material, which could include bubble wrap, plastic bag, wool, cotton, foam, tin foil etc., Small containers big enough to put wrapped ice cubes in. How to do it Step 1 - Choose which materials you think will keep his lunch cold for the longest. Step 2 - Wrap up each ice cube singly, in one material each, being careful to have the same number of layers for each material. Put each wrapped ice cube in a container. Remember, we are trying to make this a fair test, so what else do you need to keep the same? Step 3 - Decide where to put your ice cubes and how often to check them. What signs will you look for to tell you which material works best? Step 4 - Why do you think some ice cubes are melting more quickly than others? Do you think the cold from the ice cube is getting out, or the warmth from the air is getting into the ice cube? Step 5 - Which material kept your ice cube frozen for the longest? When you have decided which material is best, design a lunchbox to keep Santa’s lunch cool this Christmas Eve. What is thermal energy? Materials melt because of heat, a form of energy (thermal energy). All objects are made up of particles which are in a constant state of motion. Cold objects have less thermal energy than warm objects and the particles which make them up will be moving much more slowly. If we put a cold object next to a warm object, they will exchange thermal energy until they achieve thermal equilibrium – and become the same. We can stop or slow down this energy exchange by using a thermal insulator. Good thermal insulators have very strong bonds to hold their particles in place, stopping the particles from moving around easily and transferring energy to other particles.

Learn about liquid and gas in this fun science experiment to make a snow blizzard In this simple and festive activity for kids, students will create a snow blizzard in a jar! This activity can function as a fun science experiment for the young engineer at home or as a full lesson in school to think about gas and reactions. What equipment will you need? A jar, A pot for mixing paint, Water, Baby oil (enough to fill ¾ of your jar), A small amount of glitter, Bicarbonate of soda or an effervescent tablet, A small tube of white paint, Blue food colouring, A stick for stirring How to do it Step 1 – First, fill the jar until about ¾ full of baby oil. Step 2 – Mix water and a few tablespoons of white paint in the pot. Step 3 – Return to the jar of baby oil and add the glitter and blue food colouring. You can add as much of these as you like – you are creating a magical winter scene! Step 4 – Add the paint and water mixture into the jar, filling it to the top. Step 5 – Lastly, add a teaspoon of bicarbonate of soda. Adding the bicarbonate of soda will start the blizzard! The science behind the experiment Oil is less dense than water, less heavy; This means the water sinks to the bottom of the jar, and the oil floats on top, and as they don’t mix, there’s a separation between the two. When you add the bicarbonate of soda or an effervescent tablet, it reacts with the water to produce carbon dioxide gas bubbles. These stick to the water droplets. The water and gas combination is less dense than oil, making them rise to the top of the jar and create pressure in an upward direction. At the top, the gas bubbles pop and escape into the air, leaving the dense water behind to sink back to the bottom again. This reaction creates our beautiful blizzard in a jar! The engineering context Understanding the way different materials work and the properties they all hold is vital in creating and developing solutions to our world’s problems. Engineers are interested in the world around them, which is a fun and critical spark to ignite from an early age. Download the Snow blizzard in a jar activity sheets for free!
