Make a trap to detect Santa
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!

Insulator experiment
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.

Light up Rudolph's nose
In this Christmas STEM activity for kids, students will test a simple series electrical circuit in an attempt to make Rudolph’s nose light up.
This experiment will encourage students to have fun with electronics and understand circuits.
What equipment will you need?
Rudolph template, Stiff piece of card the same size as the template, Block of wood, 2 crocodile leads, 1.5V or D size battery, A 2.5 bulb with holder, Sticky tape, Blu-tac
How to do it
Step 1
Please print off the Rudolph template and stick it onto a stiff piece of card.
Step 2
Make a hole (large enough to put the bulb through) where the nose would be, keeping the bulb holder at the back. Tape the bulb holder to the cardboard to hold it in place. You can paint the bulb red with a felt tip pen or add some red acetate. Sweet wrappers work well for this!
Step 3
Stick the block of wood to the bottom of the card so that the Rudolph template stands up.
Step 4
Attach the crocodile leads to the metal part on each side of the bulb holder. Stick the battery down on top of the piece of wood at the back with a piece of Blu-tac. You are now ready.
The science behind the experiment
Electricity will only flow when there is a power source within a complete circuit of conductive material with no breaks.
There is no need, at this stage, to explain what electricity is or how it works, but children can begin thinking about what electricity does.
Encourage the children to look around the room to find other things which work on electricity.
They could cut out pictures from magazines of things which work on electricity and then sort them into those which work on mains electricity and those which work on battery power.

Make electric dough
In this fun science activity for kids, students will make play dough that can insulate or conduct electricity.
Make colourful dough with salt and another with sugar to find out which one will work! Through this process they will learn about conductors and insulators. Students will also learn about ionic bonding.
This is a resource that encourages learners to have fun with science. An activity sheet is available to download for free.
We have also included a bonus wordsearch using terminology from the activity to promote sticky learning.
