About this time of year I always get emails or messages about effective and fun Halloween science projects. Whether you home school, are a classroom teacher, or are having a party at your house, the following ideas can help make your day go smoothly!
One really cheap idea is to make make screeching balloons. All you do is place a penny inside a balloon. Blow it up (with the penny in it), tie it off and swirl. This makes the most irritating sound, hence screeching balloons! You can also use a hex nut in place of the penny, but in my experience, the hex nut normally has some uneven pieces and pops the balloon...Tie this in with a unit on sound...
Another idea is dry ice. Now I do NOT believe children should be in contact with the dry ice. Use this as a presentation idea only. Place dry ice in various sized and shaped containers. Add glowing powder, or glow sticks and turn out the lights for an interesting effect. Add some Dawn Dish soap to the water, then add some dry ice, and get a bubble effect. And of course, no party would be complete without dry ice drinks. Again, make sure an adult is in charge and no children get dry ice! If you are doing this in science you can talk about liquids, solids, and gases.
The most requested activity I am asked to make is "slime". I like to use Elmer's Gel Glue, but if you can't find any, use regular glue. Empty an entire bottle into a bowl. Fill the empty glue bottle with hot/warm water. Empty into the same bowl with glue. Mix together well. At this point, you can add food coloring if you want, or some glow powder, or glitter...In another bowl mix a spoonful of borax laundry detergent with a few tablespoons of warm water...Slowly mix the borax solution into the glue solution. This forms the slime, which can be taught in science as polymers.
These are just a few ideas that you can do quickly and without spending too much! Have a Happy Halloween!
