Halloween season may be a spooky season for all, but it is also a great time for fun science experiments! A lot of these experiments can be done using household items which makes it an easy going activity. When you aren’t out pumpkin picking, try these science experiments at home that will leave your kid wanting for more learning and play.

1. Haunted Halloween Hand Melt: This salt and ice experiment is a perfect Halloween science activity for home. Not only are these haunted hands fun to make, kids will learn how ice and salt react together making this a nice little science experiment to have fun with at home. For this science experiment, you will need: surgical gloves, twist ties, craft items such as beads, straws, buttons and any old craft item lying around the house, water and some food colouring. To start off, drop all the items collected in the gloves and fill it with water. Add a few drops of food colouring and use the twist ties to tightly secure the glove. Then, give the hands a little shake to distribute the food colour evenly throughout the glove. Next, take the water filled gloves and pop them in the freezer overnight. The next day, take the frozen hands out of the freezer, and remove the gloves by making several cuts in the glove. Once you manage to separate the gloves from the frozen hand, the next fun step is melting the ice with salt! Round up an interesting collection of tools and instruments for the kids to melt the ice and dig for their treasures with. You will need salt, some pate knives and wide paint brushes. And off you go - sprinkle the salt on the frozen hands and watch the ice slowly melt away. Make your kids dig for their frozen treasure and have a fun time in your backyard

2.  Spooky Expanding Ghost: For this fun Halloween experiment, you will need an empty water bottle, a balloon, a small funnel, some baking soda, half cup vinegar and a marker to draw a cute or spooky face on your balloon. To begin this fun experiment, pour half a cup of vinegar into an empty water bottle. Draw a face on your balloon if you’d like while it’s deflated.Then, place the funnel into the open end of the deflated balloon and pour in the baking soda. Secure the open end of the balloon onto the top of the bottle being careful not to dump the contents of the balloon into the bottle quite yet. When you’re ready, hold the balloon upright allowing the baking soda to fall into the bottle and mix with the vinegar. And voila, you have a spooky ghost! The mixing of the baking soda and vinegar produces carbon dioxide which makes the balloon float. It’s that simple and that fun. 

3. Bubbling Brew: Gather a bowl, baking soda, white vinegar, food coloring, dish soap, eyeballs for a fun chemistry experiment. Add a heaping amount of baking soda to your bowl. Make sure to place your bowl on a tray, in the sink, or outside because this experiment can get messy. Add a squirt of dish soap and food coloring to the baking soda. Alternatively, you can also mix food coloring into the vinegar. Time to add your spooky Halloween eyeballs or other accessories into the cauldron. Now go ahead and pour in white vinegar onto the baking soda and watch the bubbling brew start up! Science doesn’t have to be complicated for young kids. It just needs to get them curious about learning, observing, and exploring. This fizzy Halloween activity is all about a cool chemical reaction between baking soda and vinegar. 

4. Magic Pumpkin: This simple kids’ science experiment is a must-try this fall! Just grab a handful of Reese’s Pieces and a cup of hot water and you’re ready to make a jaw dropping magic pumpkin. Take a white plate and arrange your Reese’s Pieces in the shape of a pumpkin. Place the orange candies in a circle to form the sides and use four brown candies to make the stem at the top. Then slowly pour some hot water on the outside edge of the pumpkin. You need just enough to cover the bottom of the plate. And just sit back and watch the water work its magic. The shells of the Reese Pieces are made with food coloring and sugar. When the candies come in contact with the hot water, that sugar dissolves into the water and the colors spread across the plate, filling the pumpkin. This science activity is a simple way to introduce states of matter to kids.

5. Tea Bag Ghosts: To prepare for this activity, grab a stack of tea bags, scissors, a non-flammable plate, a black marker, and a lighter. Ask your kid to take a tea bag and the scissors and cut the staple end off the top. After carefully dumping out the tea, draw a simple ghost face on the now cylindrical tea bag and balance it upright on the plate. Maintain some distance from the tea bag and then light the top of the ghost. The tea bag will burn down and the little ghost will simply vanish into a pile of ash on the plate. This is because air takes up space inside and outside the tea bag due to the heat. Sounds fun, doesn’t it?

6. Pumpkin Oobleck: Oobleck is a fun mixture to play with, which is made from cornstarch and water. It’s a bit messy too. It is a great example of a mixture!  A mixture is a material made up of two or more substances combined together to form a new material and that can be separated again. For this activity, you will need cornstarch, water, a pumpkin and some spoons, a bowl and some cookie sheets. First, cut the pumpkin in half and remove all the guts and the seeds (keep some seeds aside for later). Measure one cup of cornstarch and half a cup of water and pour it into the pumpkin. Mix well with your hands and make sure the mixture is not too runny or too dry. Place the pumpkin on a cookie sheet or in a shallow tub for easy play. This definitely can get oozy and gooey and provides quite a sensory punch.

These fun Halloween science experiments are sure to keep your kids at home occupied. It’s a perfect means for hands-on learning and young kids can learn so much from the materials commonly found around the house.
