  2. Add more baking powder on top of the bunny so it is completly hidden.
  3. Next add some glitter on top of the baking powder (optional) Overhead view of two small cups filled with white powder and topped with pink and blue chunky glitter, placed on a white tray beside jars of pink and blue glitter and tubes of pink and purple paint.

Pink and purple paint tubes sit beside the cups, showing the step of adding color in an Easter fizzy surprise STEM activity before the bubbling reaction begins.
  5. This is the point to get your child involved. Use a dropper to slowly add vinegar to the bottles. Watch as the mixture bubbles, foams, and rises. Hand squeezing a purple bulb dropper to add liquid into two small cups filled with white powder and glitter on a white tray. The step shows liquid being added to create the bubbling reaction in an Easter fizzy surprise STEM activity, with pink and blue glitter visible inside the cups.
  6. Continue adding vinegar a little at a time. Let the fizz settle, then add more. Two small cups overflow with bright pink and purple foam as the fizzy reaction bubbles up inside a white tray filled with blue and silver glitter. The colorful mixture spreads and sparkles, capturing the exciting chemical reaction in this Easter fizzy surprise STEM activity.
  7. As the baking soda dissolves, the hidden Easter surprise will slowly emerge through the bubbles.

The science behind the fizz!

When baking soda and vinegar are combined they create a fizzy reaction. The bubbles created are due to the carbon dioxide gas escaping. This causes the potion to fizz up and it feels really magical for young kids.

Preschool don’t need to understand the science behind the reaction to enjoy it but older children might ask questions and like to know what is going on.

Top tips for this Easter STEM activity

Use a tray underneath your bottles or jars to keep the escaping liquid contained. This makes cleaning up a lot easier. You might even like to do this activity outside so that mess is less of a concern.

Try adding different colours of food colours to layer the fizzing effects.

Benefits of this fizzy Easter Surprise activity

There are loads of benefits of preschool science activities like this fizzy Easter surprise activity. This STEM activity is a great introduction to chemical reactions and that mixing things together can cause changes.

Here are more benefits for your child:

Hands-on science exploration – In this activity children observe cause-and-effect as the vinegar reacts with the baking soda. This is a great early, introduction to chemistry.

Fine motor skills development – Let your child use the dropper and this strengthens the hand muscle. It also supports hand eye coordination which is needed for writing and self-care skills (doing up buttons etc).

Two small flasks sit in a white tray as bright pink and deep purple foam bubble up and spill over into a sparkling layer of blue and silver glitter. The colorful fizzy reaction spreads across the tray, showcasing the exciting hands on Easter STEM activity in action.

Sensory exploration – In this activity there are fizzing sound, rising bubbles, bright colours and glitter. This creates a lot of sensory experiences and also holds your child’s attention.

Teaches patience and anticipation – Waiting for the surprise to appear encourages kids to slow down, observe, and stay engaged through the entire process.
