Your investigations and challenges!

Thank you to everyone who entered our competition and shared your investigations. We have loved seeing all of your incredible experiments! Be inspired by these budding scientists and scroll down for even more ideas to try at home.

Eloise-Mae’s flying disc project

“I used a motor module, an on/off switch, spring connectors, a box base with holes and a flying disk. I connected them all by slotting the wires into the spring connectors, I then turned the switch on and it made the flying disk spin really fast. When I turn the switch off it flies up in the air.”

Elouise is holding her disc project. She is wearing a laboratory coat and smiling.

Charlie’s balloon experiment

Charlie ran a night at his local cubs group to show these experiments as science week was coming up.

The balloon experiment was very successful and they used different ratios of vinegar and bicarbonate soda to see how well the balloon would inflate. This was a great experiment for Charlie as he had the help of his cubs to pour the ingredients yet could feel the volume increase in size of the balloon once the reaction occurred.

His ability to use the circuit as he finds this really interesting was easy for Charlie so he could help his fellow cubs if they struggled. They were all super impressed with his science night.

Prize draw winner
The sisters have created 4 race lanes on a table separated with bricks. Each lane has a different textured surface. Rebecca is holding up her car ready to race.
And we're off! Rebecca has pushed her car on the carpet surface, it looks like it has travelled about 30cm.

Dayzie’s longest noise challenge

Ryder has used bricks to create the shape of his race track. Toy figures line the barriers of the track. It is flanked by Welsh flags and a Cardiff City scarf.

“I asked my Alexa to play a long loud noise!”

“It went amazingly well I melted a big ice cube in the microwave in 1 minute 28 seconds.”

Benjamin’s periodic table experiment

Benji made his own experiment. He is obsessed with the periodic table, he ordered his favourite element, sodium, and put it in a tub of water. He wanted to see how long it took for a reaction to take place, as this years VICTA science theme is time.

Benji loved listening to the sodium hiss in the water, even more than that he loved hearing the bang of the reaction. Benji has light perception only, and was ecstatic when he saw the grass light up!

Freddie’s journey stick

Mum was at work, so grandma took me and my sister for a long walk. We found our sticks and then looked for interesting things to attach to them with some string. I found moss, interesting twigs, Forsythia Broom Ivy and leaves of different shapes and colours. My twin sister helped me and made her own journey stick.

Prize draw winner
Freddie is in his garden holding up his finished journey stick. There is moss, leaves and towards the bottom, there are bright yellow flowers.

A journey stick

It was fun, I loved finding everything in the forest. My stick is very colourful, I love it.

Challenge time…

Melt an ice cube as quickly as possible

Ice cube plus whatever you choose to help you melt the ice cube. Does something help melt the ice cube quicker than something else? Why?

Timings, solids/liquids, heating/melting

Time how long it takes you to melt 1 ice cube. Now try and melt 10 ice cubes using the same method. Does it take 10x as long? If not, why not?

Build the tallest freestanding tower

Use whatever equipment you like but it must be freestanding!

Geometry, forces, design

Restrict your building materials to just dry spaghetti and marshmallows. Is this easier or harder? Did you need to change how you approached the task?

Make something spin for the longest time

Something to spin and a surface to spin it on.

Speed, rotation, axis, momentum

Which surface is the best to spin an object on?

Make the best paper plane from toilet roll

Toilet roll

Gravity, aerodynamics

Does the plane fly better with more or less sheets?

Experiments in time…

The theme for this year’s British Science Week is ‘time’! We’ve gathered some of our favourite activities for you to try (with adult supervision). Which will you enter into our competition? The clock’s ticking… !

Lego Braille Bricks

LIFE CYCLES

Caterpillar to butterfly

This activity from LEGO demonstrates how you can use your LEGO Braille toolkit to transform a caterpillar into a butterfly. If you don’t have a LEGO Braille set why not use non-braille LEGO pieces? Can you think of any other animal life-cycles you can build?

Make a salt dough ammonite fossil

Make and bake your own ammonite shell (most ammonites died out 66 million years ago, at the same time as dinosaurs). Once you’ve created yours why not create a fossil hunt in your garden?

PHYSICS

How fast can your balloon car go?

The science buddies website explains how you can make a balloon car at home and learn about all three of Newton’s laws of motion! Once you’ve built your car, can you think of ways to make it go faster or slower? Mark yourself a start and a finish point, how long does it take you to get the car from A to B? Let us know what you find out to enter the competition.

Make a volcano and time its eruption

Record the height of your volcano, how much vinegar and bicarbonate of soda you use, and how long it takes your volcano to erupt. What happens if you change these elements? Share your findings into our competition so we can compare what created the fastest and the slowest volcanic eruption. We can’t wait to find out!

Use science to make instant ice cream

Time waits for no man when it comes to desert! The Science Museum’s Wonderlab challenges you to explore states of matter in the tastiest way – by instantly turning milk into ice cream! Explore time by changing the quantity of salt and find out if that effects how long it takes. Other activities we love on the Wonderlab site include ear gongs, oobleck and tune boosters!
