Dino ❄️Frozen 🎈Balloon Eggs Kids ⚗️Science Sensory 💦Water Play

We are continuing our Dinosaur Unit study, and today, we are rescuing frozen Dino eggs which were found by the young paleontologists during a recent trip to🇦🇶Antarctica. 

 To help with this kids science experiment, we are using a child-sized hammer, salt, and warm water.  

First, place the dinosaurs inside the balloons. We are using mini Dinos from a puzzle sets. See here our Dinosaur Puzzles blog post or buy a puzzle with these mini Dinos here.

Fill the balloons with water and place them into a freezer. Take this opportunity to discuss physics and the state of the matter: how the water changes from liquid to a solid state under lower temperatures.

Once the balloons are frozen solid, offer your child to peel off the balloon, revealing frozen "eggs."

Offer mittens, warm water, and salt to help rescue the frozen dino eggs.

With the help of warm water and salt, our dino friends are emerging. 

 Advise your child to carefully remove dinosaurs from the ice egg.
During this water sensory play, Adrian managed to rescue his Dino friends from the ice by defrosting eggs with salt and warm water. 

Science⚗️Mystery Revealed: salt is a great ice melter because it causes “freezing point depression” ~ meaning that salt helps in lowering the freezing point and, consequently, the melting point of water (the main component of snow and ice). Generally, water freezes at 0°C or 32°F; but by using salt, that freezing point can be lowered which forces the ice to melt and prevents the water from freezing or re-freezing. Please note that salt alone can not melt ice; salt must be combined with water first to start the melting process. When salt touches water, it starts to dissolve, thus lowering the freezing point and melting the surrounding ice. Voila!
