Baking Soda and Vinegar Color Mixing Activity

baking soda and vinegar color mixing My kids love making baking soda and vinegar science experiments. We’ve made many versions over the years but this one was probably my favorite. My four year old has been a little obsessed with color mixing and my son loves a good mystery, I decided to put these lessons together in a fun mystery for them to solve.  They had a blast doing it and playing with left over materials after too. For younger kids who aren’t up for solving mysteries don’t use colored vinegar just hide the colors in the baking soda and left them erupt. Just as much fun but simpler for little ones.

Gather your materials. You will need a container for each color, a small measuring cup for the vinegar, baking soda, a measuring spoon, red, blue, and yellow food coloring. color mixing with baking soda and vinegar science

Start by putting some baking soda into your containers. Add the yellow food color in one and red in the other. Cover with s little more baking soda so your child can see what color might be hiding under the baking soda.color mixing mystery for kids

Pop a few drops of blue food color in the vinegar. color mixing baking soda volcano

Invite your detective to come and help you figure out which jar has yellow food color and which has red. Explain that all you need is the blue to figure it out. My 7 year old got the concept right away and whispered the answers in my ear ( if it turns purple it’s red, green it’s yellow) he agreed to play along and was glad he did. color mixing mystery baking soda and vinegar volcano

My daughter poured the first one and at first it didn’t turn purple, I had too much baking soda on top of the red food coloring. color mixing volcano

We mixed it up and voila purple!  Then I prompted ” What makes purple? Your vinegar was blue…” color mixing mystery purple

“I know red was hiding!!”

The next jar was for my son. color mixing science experimentHe was playing it cool and could guess what would happen but he still loved it. My daughter was super excited to declare that it HAD to be yellow in the jar because the bubbles turned green!color mixing science mystery

After the mystery was solved I handed them the extra baking soda and vinegar and let them go hog wild. I was already going inside to let them play when I heard him say ” This is going to be epic!” so I clicked this shot.  A few seconds later the measuring cup was spewing and giggles were plentiful. hog wild

Books About Color Mixing

white-rabbits-color-book-alan-baker

White Rabbit’s Color Book by Alan Baker is a classic in my mind and if you have never read it you must. It’s not a complicated story, instead it’s a brilliant book and lesson about color mixing . The cover illustration of the bunny in the paint always makes me think of dyeing Easter eggs which is another great opportunity to teach about color mixing. Kids love this book and adults reading it will enjoy the fun and dynamic language used to describe the vibrant colors that the bunny plunges into.

little-blue-and-little-yellow

Little Blue and Little Yellow by Leo Lionni is a profound book with underlying commentary about race relations while the surface story is about little blobs of color who when squished together turn into one green blob! You’ll be surprised by how easily your preschooler will pick up on the connection between the two. In my PreK class I had more than a few kids make the connection all on their own.

mouse paint

Mouse Paint by Ellen Stoll Walsh is a cute little story about mice that get into paint and not only make a mess but discover what happens when you mix colors. Great for every day but even better when you are learning about colors specifically mixing colors.

 

 

Color Lab Science For Kids

color science for kids What would happen if we put watercolors in shaving cream? What about vinegar ? Or oil? Great hands on science always begins with ” I wonder…” and this color lab science activity was no exception. We wondered what would happen if we mixed water colors and different household liquids. After we explored our set questions it was time for completely kid directed play. We used liquid watercolors made with plain old paint instead of food color to avoid staining. Food color will make much more vivid colors.

Gather your materials. We used water, vinegar, shaving cream and oil for our liquids, liquid watercolors, some jars, an eye dropper, a cookie sheet, and goggles! color lab for preschool

Start by making liquid watercolors. Pop the disks out of the watercolor tray and add a little water. Sit for a few minutes and stir. liquid water color lab

Now you are ready to set up your color lab! Pour the liquids in ( I did the shaving cream) . color lab science for preschoolers

Time make a few predictions.

Grab your eye dropper and start adding colors. The eye dropper is important because it gives this activity an element of fine motor development as well, it takes a lot of coordination to make eye droppers work and works out the pincer grasp too. color lab water

She noted how slowly the colors floated down through the water.

The colors seems the same in the vinegar. I asked her if anything was different and she said the smell! Observing is a huge part of science!

The shaving cream was interesting because the color spread over it but didn’t mix much. She also discovered that if she pinched the eye dropper really hard the watercolor made a hole in the shaving cream. color lab shaving cream

The oil was rad. She had no previous experience with water in oil.  color lab oil wowShe was amazed when they turned into little dots of color and slowly sank down to the bottom. I loved seeing her experience this for the first time. color lab oil

Time to play. After going through each liquid it was time to mix them all together. mxing  color lab science

The shaving cream didn’t pour as well as the water did. color lab science pretend play

Kitchen Science For Kids { What will freeze first?}

kitchen science experiments for kidsWhen it comes to science I usually let my kids lead with questions and suggest we investigate from there. One morning last week my son didn’t finish his milk and I asked him to please pop it in the fridge so he could have it with his lunch. Instead he asked if he could put it in the freezer to see what would happen. Of course I was game. After he put it in the freezer I asked him what he thought would happen. At 6 it was no shock that he thought it would freeze, so I asked him how long he thought it would take. That sparked this simple kitchen science experiment we did a few days later. My kids love kitchen science for kids and I love doing it with them. Fun together time with science!

Our question was:  Which kitchen liquid would be the first to freeze ?

  1. Gather your materials. You will need an ice cube tray, a line up of different kitchen liquids , a timer ( not really a must ) and a freezer. We had a measuring spoon too! Our liquids were water, vinegar, chocolate syrup, ranch dressing, dish soap, milk and apple juice.freezer science
  2. Start by filling your tray with the different liquids. kitchen science for kids what will freeze the fastestBefore you ask your kids to make predictions ask them what they already know about the different liquids. My kids and I noted that we freeze water all the time and it takes an hour or two. They noted that milk will freeze so they knew that more than just water can freeze. After they go over all their background knowledge ask them to make a hypothesis or prediction if you are focusing more on results not the reason for the results. If they make a prediction simply say “why do you think that will happen?” and voila you will also get a hypothesis out of them.kitchen science freezer exp
  3. Freeze it! We set my iPhone timer to go off at regular intervals.
  4. Observe what is happening. The apple juice was the first to form crystals. The water quickly caught up by the next time we checked. The dish soap had cool bubbles and was getting harder to stir, and the chocolate still tasted great although it wasn’t really ever frozen. We checked on the tray for 3 hours and by then end of that everything was solid except the chocolate syrup which still has a dough like texture days later.kitchen science activity for kids
  5. After the results are in ask your child what they noticed. My daughter noticed that the vinegar and water froze pretty easily and that the chocolate never did. My son noticed that the thicker liquids were much slower to freeze than their thinner counterparts. That’s when I jumped in with the word viscous. We talked about how the water, milk , vinegar ,and apple juice froze faster because they all have lower viscosity than the dish soap , ranch dressing and chocolate syrup. I kept it very simple explaining that the less viscous a liquid is the easier it is to take another form and for the cold to get to every part of it. The thicker liquid was harder to freeze because the cold air had to work harder to get all of it cold enough to freeze. I tend to over explain things to my kids and have learned their signals for when my answer is shifting into a lecture. If they keep asking questions keep answering them but those blank stares are a sure fire sign that you should keep it simple, at least for now! kitchen science for kids what can you freeze

The best part about simple kitchen science for kids is that it lets your children see that science is everywhere. It’s in their kitchen and is accessible to all.

Love Potions – Valentine’s Day Science Play

love potions valentine's day scienceWe love to play with vinegar and baking soda at our house . We explored it with squirt guns, at a play date and even pretending to be mad scientists. This time we made potions but really we just made a really awesome fun mess!   We made these after school this week and already my 2 year old has asked to make so many I am out of vinegar and baking soda. Kids love to pretend and mixing imagination with scientific inquiry is a great way to get them interested in asking questions and testing their theories out. We pretended we were making love potions but not the way that maybe a teenager would think about it. Instead we were making potions to make everyone feel loved, not to fall in love with us and even that fell by the wayside . Bottom line, have fun and make sure you have towels ready!

  1. Gather your materials. You will need some baking soda, vinegar and then we added  food color and food flavoring ( strawberry and cherry) . You will want clear containers, spoons, and whatever you need to protect your house from food color. love potions preschool scrience play
  2. Set out the ingredients and let them explore. While they started I talked about how some people think that potions and spells will make people fall in love and they both thought that was crazy talk! We pretended we were making people feel love but soon they just got into making a potion and the love bit was lost. This is fine the goal wasn’t to teach about love potions so much as simply explore. love potions science for kids valentine's day activity
  3. My son saw the baking soda and immediately got excited about the prospect of a fizzy overflowing potion. Only he couldn’t remember what made it bubble and discovered it was not the cherry flavoring.love potions for kids
  4. My daughter followed her brother’s lead and absolutely adored every minute. love potion science play activity for kids
  5. Once they figured out it was the vinegar they made potions over and over.love potions  In all different color combinations and with as much excitement every time. love potions 2It soon turned into making predictions about if it would overflow or not. love potion number 5
