4 Halloween Science Projects for Kids

4 Halloween Science Projects for Kids

Giant spiders. Skeletons on horseback. Pumpkins on every stoop! Our favorite spooky holiday is just around the corner. So we’ve got four Halloween science projects to set the mood and keep your little ones entertained as temperatures start to drop.

Halloween is an excellent opportunity to teach your kids about science. Seemingly simple decorations can become engaging projects. Here are the science projects we’ll undertake today:

Dry Ice Witch’s Cauldron

We’ll start with making a simple foggy witch’s cauldron. This cauldron makes a brilliant decoration, and kids have a lot of fun watching it come to life.

The instructions are straightforward, but you will need a ‘cauldron’ and dry ice.

Supplies you will need:

DRY ICE WITCH’S CAULDRON:

  • 2 Liter Plastic Container
  • Hot Water
  • Dry Ice
  • Towel
  • ‘Cauldron’
  • Hammer
  • Heavy Leather Gloves

Dry ice is so cold it can burn you if you aren’t careful. You will need a pair of heavy leather gloves if you plan to handle the ice with your hands.

Most people can find dry ice in local grocery stores near the front of the store. Some Wal-Mart stores carry it, so you might check there to start.

Once you have your dry ice, you’ll want to lay it out on a towel and bust it up into smaller chunks with a hammer (assuming it didn’t come in small pieces already).

Wearing the leather gloves, place some chunks of dry ice in the bottom of your cauldron.

Use your plastic container to slowly pour hot water over your ice chunks in the cauldron. The dry ice will almost instantly create a fog.

Pro Tip: You can let your kid do the pouring if they’re old enough. They’ll love it!

After a while, the water will start to cool. You can pour the cool water out and replace it with more hot water to keep your fog going.

Project 2: Static Electricity Ghosts

Static Electricity Ghosts

Another Halloween science project that’s always popular with kids is static electricity ghosts. 

Essentially, you inflate a balloon, draw a ghost face, and then use various materials to experiment with static electricity.

Supplies you will need:

STATIC ELECTRICITY GHOSTS:

  • At least 2 white balloons
  • 1 Sweater
  • Markers
  • Tissue paper
  • Cardboard
  • Aluminum foil
  • Yarn
  • Pom Poms
  • Pipe Cleaners
  • Ribbon
  • Cloth
  • Foam

Start by inflating your white balloons. Once they’re blown up, use black markers to give them a face, mouth, and any other ghost parts.

Now rub one of the balloons on the sweater to build up static electricity. 

Next, touch each balloon to the other materials, such as the aluminum foil and pom poms, so your child can discover what happens.

Using ghost balloons can teach your kid about static electricity, conductivity, and how a balloon can hold a negative charge.

Ask your child questions to get them involved and to help them understand what is taking place when items are either attracted to the balloon, repelled by it or when nothing happens at all.

Project 3: Germinating Pumpkin

Germinating Pumpkin

Dirt, decay, and pumpkins. What more could a child ask for from a Halloween science project?

Germination is the process of sprouting a seedling. In this case, we’re sprouting pumpkins, and we’ll do it inside another pumpkin. 

It’s kind of like creating Frankenstein when you think about it.

The cool part is you get to teach kids about plant life. Not just the life part but also how to grow and care for that life.

Supplies you will need:

GERMINATING PUMPKIN:

  • Small pumpkins (the tiny ones)
  • Dirt
  • Water
  • Knife (to cut the top of the pumpkin off)

First, an adult should cut the top of the mini pumpkin off with a knife to reveal the pumpkin’s ‘guts’.

Since pumpkins already have seeds, you don’t need to bring any. Some people do use seed starter, but it probably isn’t necessary.

Okay, now you’re going to fill the inside of the pumpkin with dirt (and by *you* we mean your kid). 

Once it’s filled up, you can water it lightly and then sit the pumpkin somewhere it will get sunlight. 

Water it once a day, and within a week or two, you’ll start to see changes!

One of the first changes you’ll notice is that the original pumpkin is rotting. However, as the old pumpkin rots away, a new pumpkin is born and sprouts up out of the dirt!

Amazing!

It’s a bit of a slow burn, but that’s also a lesson in patience, so the wait is kind of a bonus.

Project 4: Squishy Monster Eyes

Squishy Monster Eyes

For our last Halloween science project, we’ll switch gears and get extra spooky with monster eyes!

Many of you made these as kids, but even if you didn’t, you can still experience the joy of doing it now with your kids.

For this one, hand your child a raw egg. 

Ask them if they can remove the eggshell without making a mess. 

Naturally, they’ll say you’re out of your mind (and that’s where the fun begins).

Supplies you will need:

SQUISHY MONSTER EYES:

  • Eggs
  • Vinegar
  • Mason Jars
  • Food Coloring (Halloween colors)
  • Large bowl
  • Tablespoon
  • Towel (to clean up messes)

First, set the egg down in your mason jar or cup. 

Next, pour vinegar over the top to fill the container enough that the egg submerges (if the egg floats, that’s okay).

Now add your food coloring. Gently mix it in with a spoon or stirrer if you like to ensure it evenly distributes. 

Almost immediately, carbon dioxide bubbles will start to form on the egg’s shell as a chemical reaction begins.

Let the egg sit in the vinegar for 24 hours, and then replace the liquid with fresh vinegar. Now let the egg sit for an additional 24 hours. 

It is important that you allow the egg to sit in the vinegar for 24 hours each time so the process can reach completion.

After 48 hours have passed, remove the egg from the vinegar, and rinse it off. 

It’s ready! 

Let your kids squish it, bounce it, and play with it (until it inevitably falls from a table and breaks on the floor)!

After Halloween Science

Even when Halloween is over, you can still get your kids involved in fun science projects. 

iCode School was explicitly designed for that purpose. 

Our instructors work with kids daily on unique science, technology, engineering, and mathematics projects to help them learn and grow. 

Kids learn from hands-on experience and alongside other children just as interested in science projects as they are!

Thanksgiving is a few days away. Kids are out of school. If you don’t find something to catch their attention, they’ll go stir-crazy waiting! So today, we’ll look at ideas for interesting Thanksgiving weekend STEM fun for kids that will keep their minds occupied.As you may know, science, technology, engineering, and mathematics (STEM) are booming fields for the employment sector, but that doesn’t always translate into “fun for kids.” So how can you bring learning to your children for Thanksgiving and get them interested in STEM?Easy, just share one (or all) of these fun ideas to engage their minds, and redirect them to STEM-focused activities. 1. Reveal the Volume of Turkeys Consumed Each Year Our first idea starts with a huge number.Each year in the United States, Americans consume around 46 million turkeys which equal around 704 million pounds of turkey.Clue your kids into the volume of turkeys consumed each year, and ask what other numbers they can turn that into.If divided by 275 million people (the number of people expected to eat turkey on thanksgiving), how many pounds of turkey is that per person? You could even ask silly questions to spark their computational thinking skills.How many turkeys would fit…
November 8th is National Science, Technology, Engineering, and Mathematics (STEM) day - a non-traditional holiday created by MGA Entertainment in 2015 to highlight critical academic areas. You may not get a paid day off, but we do have some ideas for how you can celebrate National STEM day with your kids.Here’s an overview: 1. Build an Apple Boat and See if it Floats A fun and cost-effective way to celebrate National STEM Day with younger kids is an apple boat project. Ask your child if they think apples float or sink. Once you get their response, you can test their hypothesis.Steps to Make an Apple Boat:Slice an apple in half.Cut a triangle from a piece of construction paper.Attach the triangle to a toothpick with tape or glue.Insert the toothpick into the apple slice.That’s it, you’re ready to float! Have your child place the apple boat in a bowl of water to discover what happens. Afterward, explain that apples float because they are buoyant. In other words, the apple has air inside of it that helps it stay afloat. Since apples are less dense than water, they do not sink. This project not only covers science but introduces elements of engineering too! 2.…
