Grow the Grinch’s Heart Science Experiment

November 20, 2018 By Terri Thompson

One of the best parts of How the Grinch Stole Christmas is this scene: the Grinch is straining as he holds the sleigh balancing precariously on a mountaintop. He hears singing and then pop, pop, pop, his heart fills with joy.

I love watching How the Grinch Stole Christmas every year and I was dying to do an activity based on this favorite movie. So, we took a classic science experiment, gave it a Christmas-sy twist to get this fun Grow the Grinch’s Heart Science Experiment.

Try some Christmas science with this fun Grow the Grinch's heart science experiment. It's a STEM activity with a Christmas twist.

Supplies Needed:

Green balloon
Red Sharpie
Empty water bottle
White vinegar
Funnel
Baking Soda

Before you begin your project, you’ll want to make the Grinch’s small heart.

Take a green balloon and use your red Sharpie to draw a simple heart on the balloon.

Give it a minute to dry before you begin your grow the Grinch’s heart science experiment.

Grow the Grinch’s Heart Science Experiment.

For the first step in your experiment, add some vinegar to your empty water bottle. I filled it up to about the second groove from the bottom. Eyeball it. You don’t need to be exact.

Attach your balloon to the bottom of your funnel (like the picture above). Fill the balloon with about two to three spoonfuls of baking soda. You may need to shake it a bit to get all the baking soda into the balloon.

Remove your balloon from the funnel.

Carefully, without dumping any baking soda into your bottle, attach the balloon to the top of the water bottle, like you see illustrated in the photo above.

You’re all set up! Get ready to grow the Grinch’s heart.

Grow the Grinch's heart with this fun Christmas science activity based on this favorite book. It's a STEM activity with a Christmas twist.

Lift the balloon up and shake the baking soda into the bottle. Your balloon will start inflating immediately.

You can let go once the balloon starts filling up and watch the Grinch’s heart grow three sizes (or more).

Why did the Grinch’s heart grow?

The combination of baking soda and vinegar formed a gas called carbon dioxide, which filled your balloon.

This is the same gas that forms the bubbles in your favorite carbonated drink.

Have you watched How the Grinch Stole Christmas yet this year?

When you do, add a little extra fun when you do this grow the Grinch’s heart science experiment.

Hot Chocolate Science Experiment

October 17, 2018 By Terri Thompson

I love my girls’ natural curiosity when it comes to science. So, when my daughter asked me “Can we do a hot chocolate science experiment?” I knew it was time to get creative.

Working together, we came up with an amazing STEM activity.

When we make instant hot chocolate, we dissolve the contents of the packet into hot water. We decided to find out if temperature affected the speed that it dissolves.

This hot chocolate science experiment is a fun way to learn about how temperature affects the rate at which hot chocolate dissolves. It's a great STEM activity that uses items you probably already have in your kitchen.

Let’s get started!

Supplies Needed for Your Hot Chocolate Science Project

First we needed to gather our supplies. Luckily most of the items were already in our kitchen.

Here’s what you’ll need:

Three heat-proof mugs
Three packets of instant hot chocolate
Measuring cup
Water
Spoons
Stopwatch or timer
Notebook for recording your results.

How to Do Your Hot Chocolate Science Experiment

We started our experiment by making a prediction. Which temperature of water would dissolve the hot chocolate the quickest?

The girls made their prediction (they chose hot) and then it was time to experiment.

We started by emptying our hot chocolate packets into our mugs, one packet per mug. Then we moved on to testing the different temperatures of water.

We tested each temperature, one at a time. We were very vague with our temperatures, using ice cold water, room temperature water, and hot water. You can always add a kitchen thermometer to measure the temperature of the water to add an extra measurement element to your experiment.

My girls took turns measuring the water, stirring, and operating the stopwatch. We used the digital stopwatch on my phone to time how long the hot chocolate took to dissolve.

For each cup, we measured 6 oz. of water. We used cold water from our refrigerator over ice, lukewarm water from the tap, and I did my grown-up duty and heated water in the microwave for the last mug.

Once the water was added to a mug, one girl started the stopwatch and the other started stirring. We stopped the stopwatch as soon as we saw the hot chocolate had dissolved.

Does Hot Chocolate Dissolve Faster in Hot Water or Cold Water?

We started with the ice cold water. My oldest daughter was in charge of the stirring. She stirred and stirred and stirred some more. It wouldn’t dissolve. Eventually, we made the decision to stop after three minutes. You can see the results above. Disgusting!

We moved on to the room temperature water, which clocked in at 1 minute 38 seconds. And, then the hot water, which only took 28 seconds.

The results: hot water takes the least amount of time. We predicted that because the instructions said to use hot water when we made hot chocolate. (And, it’s called hot chocolate after all…) But, now we know why we need to use hot water.

Why Does Hot Chocolate Powder Dissolve Faster in Hot Water?

Hot water has more energy than cold water. With more energy, the molecules in the water move faster breaking down the hot chocolate mix quicker.

Once we finished writing our results, we unceremoniously dumped the cold water hot chocolate sludge down the kitchen sink. Ick.

What happened to the other two mugs? They were topped with a dollop of whipped cream and enjoyed!

Instructions

Make a prediction. Which temperature of water will dissolve the hot water the fastest: cold, room temperature, or hot? Write it in your notebook.
Empty your hot chocolate packets into your mugs. You need three total mugs with one packet per mug.
Get your stopwatch or timer reader to start measuring your time.
Choose the first mug and add 1 cup (8 oz.) of cold water to your mix.
Start the timer and start stirring. Record how long it takes for your hot chocolate mix to dissolve.
Grab your next mug and add 1 cup of room temperature water to your hot chocolate mix.
Start the timer and start stirring. How long did this one take?
Next, grab your last mug. Have a grown up add 1 cup of hot water to your mug.
Start the timer and start stirring. Record the time it takes to dissolve.
Compare your results to your prediction. Were you right?

Notes

Use a kitchen thermometer to measure the temperature of your water if you would like. This is a great way to practice reading a thermometer and adds more data to your experiment.
