How to make Fizzy Old-Fashioned Lemonade

How to make real old-fashioned lemonade from scratch, that really bubbles! Fun edible (or drinkable) science project for kids.

Make your own Fizzy Lemonade - a tasty science project for kids. GSK

I’ve been wanting to make homemade lemonade with the kids for AGES! It’s one of those classic “must-do” childhood activities, and if you make yours with an acid-base reaction like we did, it also doubles as an impressive & tasty science demonstration.

There are different ways you can add bubbles to (or carbonate) drinks. One way is to use something like a soda stream which forces carbon dioxide gas (Co2) from a pressurised cylinder into drinks, making them fizzy. Another way is to produce an acid-base chemical reaction, which creates the carbon dioxide from within the drink. That’s what we’ve done with our homemade lemonade recipe here. And the best bit is that our recipe doesn’t require a fancy soda stream machine – it uses common pantry items that you probably already have at home.

We’ve played around with acid-base chemical reactions in the kitchen before, like when we made Anzac biscuits, or our Violet Crumble honeycomb bars, and let’s not forget our homemade sherbet! There’s something so impressive about watching things froth up and bubble, especially when you get to taste them afterwards.

Our lemonade recipe will taste a little different to the store-bought lemonades that you might be more used to. Fair-warning that the baking soda does have a slightly soapy after-taste. But if you add enough sugar (!), and if your kids enjoy the process, then the results are certainly impressive and memorable . We made two glasses of lemonade, (reducing the quantity of baking soda in our second glass, until we found our ‘sweet spot), and my kids are asking to make more today, so I think that means it was a winner.

Tasty science is fun for any age! You could try this from preschoolers through to primary school aged kids – Bumble Bee was 7.5 years old when we did this at home.

Younger kids will be fascinated by all the bubbles in this demonstration, and it can start to develop their understanding of acid base reactions, and that ‘chemicals’ can occur naturally and be useful in cooking!

Older kids might like to turn this into an experiment (perhaps by studying the effect of varying the baking soda quantities) using the scientific method: form a hypothesis, create a fair test, by changing just one variable, and record results. They can share their findings in the comments below!

Please note…

Mixing together pantry ingredients is a safe and fun way to explore chemical reactions with kids. The ingredients used here are all generally taste-safe, however, please don’t let kids eat baking soda in its concentrated form (ie, don’t let kids eat plain baking soda by the spoonful please). Baking soda is OK to taste once it’s with the other ingredients in the lemonade.

Kids knife skills vary – use your own discretion as to whether you would like your child to try using a sharp knife, or if you would like to pre-cut the lemons for them.

All kids’ activities on this blog require attentive adult supervision. Parents and carers will need to judge whether a particular activity is appropriate their child’s age and skill level. Click here for more information.

Science + Art: Mushroom Spore Print Car Painting

Fun nature science + art idea for kids: how to make a cool car painting, using mushroom spore prints for wheels, and learn about mushroom biology!

Incorporating mushroom spore prints in kids art

Ever since we first tried making mushroom spore prints, we’ve been dreaming up fun ideas to incorporate spore printing into art or craft activities. Our mushroom monkeys were our first idea, and this mushroom spore print car painting is our second  – and I think it turned out quite well!

Zooming Hearts

Zooming Hearts – a fun Valentine’s Day science activity kids love!

Zooming hearts science activity

This is such a cute and fun science activity for Valentine’s Day (or any day)! Can you make a paper heart zoom? If you’re sneaky with the dipping part, you can also make it look like a cool party trick and amaze your friends. Science magic!
 

Suitable for

This activity is fun for a bunch of age groups, from preschoolers to grade school kids. Jewel is 9 and Bumble Bee is 7 in the videos below – they can easily do all the elements without help, but they still found it fun!

Salt Crystal Hearts

Make cute salt crystal paper hearts, fun science craft idea for Valentines Day, Mother’s Day, or just because!

Salt Crystal Hearts Science Craft STEAM idea for kids

We’re becoming salt crystal obsessed in our house. They’re so much fun to make, for little and big kids alike! And they’re a great way to introduce science concepts like dissolving and evaporating, making a solution, and cubic crystals.

This time we made cute Salt Crystal Hearts, as part of Red Ted Art’s 31 Days of Love series. Click here to see our activity!

This will be added to our crystal science activities page, or you can also find more heart-themed science activities on our new Valentines Day science page, including:

Salt Crystal Paper Snowflakes!

Stunning winter or indoor snow day craft that doubles as a cool crystal science lesson – how to make salt crystal paper snowflakes!

Salt Crystal Paper Snowflakes - crystal science project for kids 1

OK, I think I’m slightly addicted to making salt crystal crafts – we began with our ‘snowy’ salt crystal fir trees, then we made our salt crystal ghosts, and now salt crystal snowflakes! I think these snowflakes are my favourite so far: they’re quite stunning, and I love science projects that only need everyday household materials – no need to duck to the shops first!

Salt Crystal Snowflakes 8

Suitable for

This is would be a great activity for a group middle schoolers (8-10 year olds), who should be able to do most aspects by themselves. Younger kids (even preschoolers) can try this too, but they’ll need more help. (The salt crystal part is easy enough, but it’s actually the folding and cutting of the paper snowflakes that little kids will need the most help with). For reference, Jewel was 9 and Bumble Bee 7 when we did this.

This is a fun activity for preschoolers or younger school-aged kids. Bumble Bee was 6 years and 11 month olds and in year 1, when we did this at home. But because it’s taste-safe, you could try it with older toddlers as well.

Do you remember the salt crystal trees we made a few years back? Bumble Bee had just turned three at the time, and now she has only a vague recollection. So we decide to make these salt crystal ghosts to help jog her memory, and have a little Halloween science fun in the meantime. 🙂
