Separate your candy colors withCandy Chromatography from Kids Activities Blog. Create some colorfulCandy Potionswith this activity from Housing a Forest. Color Changing Fizzy Potions – Use red cabbage indicator to explore pH. We simply grabbed materials to use from the dollar store. That will have your kids squealing with grossness and delight.
Have you ever tried the rubber egg experiment? That’s what this is, but in keeping with the holiday theme by making it a monster eyes version. Make black and orange “rubber” eggs that look like monster eyes while learning all about the science of osmosis.
Ghostly Optical Illusions
In this lab activity, students explore phase changes and sublimation while comparing the change in mass of dry ice in water vs. regular ice in water. I have students use triple beam balances instead of electronic scales because it is good practice for them to adjust the hanging masses and practice their measurement skills. Well maybe you can with this easy flying tea bag experiment. All you need are a few simple supplies for a fun floating tea bag science experiment with a Halloween theme.
Ready for toil and trouble with leftover vinegar from the monster egg experiment? As another physical science activity, core your apples, add vinegar and then watch as the apples begin to bubble and boil. Add food coloring to make it look like a witch’s brew or apple spice for a delightful smell. Preschoolers will love watching this fun Halloween science experiment.
Halloween Science, STEM, and STEAM
Watch a pumpkin decompose and then regrow with this fascinating Halloween experiment. These candy experiments are perfect for October when there’s candy a-plenty. It’s a great way to use leftover candy after the holiday, too. Either way this floating drawing STEM activity is sure to impress!
Add an item to float on top like a plastic spider or a lego block to further demonstrate the density of each liquid. I even included a sensory bottle for babies as a first science play idea! These are some of my favorite Halloween science/sensory play and learn ideas from women I truly admire. Pair a fun pumpkin book with a simple rotting pumpkin experiment for all things Halloween science.
SPOOKY LIQUID DENSITY EXPERIMENT
Work in a little Halloween physics with these cute bat, Frankentstein, and ghost rockets made out of paper, straws, and tape. Lots of factors determine how well your chracters fly, such as their shape, weight, etc. Lighter and more aerodynamic characters should fly better. Here’s a little morescience behind straw rockets. This ghost in a bottle experiment is sure to get lots of ooohs and ahhhhs from the kids.
May sound scary but it’s really simply and a whole lot of foamy fun. A few simple ingredients from the grocery store and you’re exploring some great chemistry for Halloween. Science Sparks are not liable for the actions of activity of any person who uses the information in this resource or in any of the suggested further resources. Lave lamps also feature in my Top 10 Science Experiments Every Child Should Try at Least Once. They are super easy to set up and can be used over and over again.
For added drama, light up the jars from below using flashlights. You can also create floating eyeballs by drawing an iris and pupil onto ping-pong balls with permanent markers. Make a few that will float around by drilling two very small holes in the ping-pong balls and allowing them to fill with water until they sink. For an added glowing black light effect add our Glow-Bright Concentrate. Parents and teachers, here are 25+ easy Halloween science experiments for kids! These quick and easy experiments will help you use the holiday as a fun opportunity to explore some of our favorite topics in science.
Kids will love making their own puking pumpkin for Halloween with a few simple household ingredients. These pumpkin lava lamps make a great alternative to carving a pumpkin. The best thing is you can use them over and over again! Just add an effervescent vitamin tablet or alka seltzer when you want them to erupt. This would be great to give out in small tubs as an alternative to candy. Try making some bubbly witchy drinks while investigating which make the best bubbles.
Play with some extra messy, super seedyPumpkin Oobleck from Sun Hats and Wellie Boots and learn all about non-Newtonian fluids. Play in a messy sensory bin and learnWhat is Blood Made of? It’s good to be a crazy scientist when you are a kid . Explore science concepts with aSkittles Density Rainbow from Gift of Curiosity. Hypothesize and test those fun-size candy bars with aCandy Bar Science Experiment from Reading Confetti.
Shadow puppets are another very easy activity and can be made fun for older children by adding coloured cellophane for extra effect. If you have some dry ice from the Ghost Bubble Sphere left over, you might want to try this fun little demonstration. As it sublimates, the carbon dioxide gas escapes around the quarter causing the quarter to vibrate and make a rather spooky shrill along with occasional humorous sounds. Always wear gloves when performing this demonstration. All your neighbors will have Jack-O-Lanterns that glow orange, but you will impress them with a Jack-O-Lantern that glows green! Best of all, the green glow is simple and safer than traditional candles.
