Build Your Own Mini Volcano
The classic baking-soda eruption — still the best 20 minutes in the kitchen if you put it on a tray.
How to do it
Tray first. Always.
-
1 Stand a cup in a tray. Pile playdough, foil, or wet sand around it as the mountain.
-
2 Add 1–2 spoons of baking soda (and a drop of soap if you want more foam).
-
3 Pour vinegar. Cheer. Repeat with a different amount.
Shape a mountain, pour in baking soda, add vinegar, watch it erupt. Then do it again.
Is it safe?
Yes with an adult nearby. Don’t drink the mix. Rinse the tray after.
Baking soda, vinegar, a cup or bottle, a tray, optional dish soap and food colouring for foam.
Predict: more vinegar or more baking soda = bigger eruption? Test once each way.

How to Prepare for Your First Robotics Activity
What children may need
Comfortable clothes they can move in, closed-toe shoes, and a water bottle. Long hair tied back helps when leaning over kits. If the program provides tablets or robots, children usually only need curiosity — not their own laptop.
What parents should bring
A short note about allergies or sensory preferences, emergency contacts, and any pickup timing constraints. Ask the provider whether snacks are allowed. For drop-off programs, confirm the sign-in process before the first class.
What children should expect
The first session is often about exploring parts, following simple steps, and celebrating small wins. Mistakes are normal. Many robotics activities for kids start with building and play before any formal coding.
Beginner tips
Talk about trying one new thing rather than finishing a perfect robot. If your child is shy, arrive a few minutes early so they can see the room and meet the instructor without a crowd.
Simple things to practice at home
Practice following two- or three-step instructions, sorting pieces by colour or size, and naming left and right. Free block-based coding sites are optional; hands-on curiosity matters more before class.
Age-appropriate preparation
Younger kids (roughly 5–8) do best with short builds and lots of adult encouragement. Older beginners can preview how to get started with robotics using a visual coding tutorial — keep it playful, not like homework.

Quick questions
Do we need to buy a robotics kit before the first class?
Usually no. Most local programs supply shared kits. A home kit is helpful later if your child wants more practice between sessions.
Is robotics the same as coding?
Robotics often includes building plus simple coding. Pure coding classes focus more on screens and logic. KidsPact lists both so you can compare fits.
