Amazing DIY science experiments that are easy to do at home (2023)

For many, the idea of ​​science gets lost. They may feel like there is nothing fun they can do at home, or they may be worried that their children will not be impressed. However, there are many science experiments that you can do at home with your kids.

Although in general we only focus onchemical experiments, sometimes in particularexperiments with your childrenYou can find many things, but Electronics, Physics, and Chemistry are three of the most popular types available. Plus, if you're an adult and a science enthusiast, there's that tooprofessional experiment kits ready for you.

The good news is that you can find cool experiments with household items to make at home. That means you don't have to spend a lot of money and you can scour the kitchen for the things you need.

Diet Soda and Mentos Volcano

This is a classic.

If you are looking for interesting science experiments, this is the place for you. Keep in mind that it can get pretty messy, so consider doing it outdoors or in the bathroom where it's easier to clean. However, it is non-toxic and therefore safe for children.

what do you needfor this scientific experiment

  • test tube/sheet of paper
  • Diet soda in 2 liter bottle
  • Mentos-Bonbonrolle
  • index card
  • wipe (to clean)

The first step is to gather all your supplies. You can substitute other sweets for Mentos, but they work better. Regular soda can also be used, but the rash will likely be a lot stickier.

Stack the candies. To do this, you need to use a sheet of paper or a test tube to form a single column of candy. Place the index card on the piece of paper at the end so the candy doesn't fall out before you're done.

Open a bottle of diet soda. Remember that the rash will pass quickly. Make sure things are set up and you can retreat after releasing the candy.

When finished, place the peppermint roll over the bottle and remove the stopper to loosen. Let the eruption begin!

why does it work

Whether it's for a school project or science experiments for high school students, this project is great. It works due to a physical process rather than a chemical reaction.

Soda has a lot of dissolved carbon dioxide, which is what gives it its fizz. When Mentos are added, the bumps on the candy's surface allow more carbon dioxide to stick (like we covered in one of ours).100 facts about chemistry).

More and more of these molecules accumulate and form bubbles. The candy is heavy and sinks, so it interacts with carbon dioxide all the way to the bottom as the bubbles expand as they rise. The accumulation of bubbles as the candy begins to dissolve causes foam to form.

With all the pressure, a geyser erupts and foam is thrown through the narrow opening.

building ahovercraft

If you want awesome science experiments using everyday materials, you should build a hovercraft. This focuses on physics as the device glides across a flat surface without falling through gravity. It works by moving air cushions that are generated by fans at the rear of the vehicle. Underneath is a skirt that traps air and causes it to rise. A motor and fan propel it forward. Instead of a fan, he uses a balloon here.

You will need:

  • Eine CD (Compact Disc)
  • Pop top lid from a soap dish or water bottle
  • hot glue gun
  • Ballon

Glue the bottle cap to the center hole of the CD and let it dry. All edges of the inner hole of the CD must be sealed. Then press the pop top shut. Now inflate the balloon and hold it tightly so that the air cannot escape. Pull the opening of the balloon over the cap without losing air. Align the balloon so it is centered and straight.

Place your newly crafted hovercraft on a table and open its pop top. Press the device down a little and release it.

Construction of an electric motor

Most people think of car engines, but they are in your house. For example, if you have a washing machine, refrigerator, or fan, they all have motors. You can build a simple motor for an electronics science experiment, and you just need some magnets (neodymium magnets, which are usually used for magic tricks are pretty cheap) and a few other things.

You will need a few things that you may need to purchase. They include:

  • magnet wire (about 50 inches)
  • Lixa
  • Neodymium Magnets (3)
  • 1.5 to 2 inch long jumbo paperclips
  • Compass
  • Dowel, ½ inch diameter (or the cap of a felt tip pen)
  • Scissors
  • Ruler
  • Cardboard (2 × 3 inches)
  • C cell battery (2)
  • Masking or electric faucet

How to build your own electric motor at home

Measure 1.6 inches from one end of the magnet wire and start wrapping it around the cylinder about 10.5 times. Cut with scissors, leaving 1.6 cm free. You must do this evenly and cleanly. Otherwise the weight will not be evenly distributed and the experiment will not work properly.

Slide the magnetic loops off the cylinder. The coil can look square or circular at this point. Make sure the loops stay grouped together. Thread the free ends of yarn through the bobbin thread loops at the 9 and 3 o'clock positions. Make sure the wire ends are straight. This is the axis on which the electromagnet rotates.

If necessary, remove the insulating varnish from the ends of your cable to make electrical contact between the bracket and the shaft. You can use sandpaper for this. Do not press too hard as the thread may break. Make sure that you only pull off the upper half of the housing on the right-hand shaft. On the left side, remove all lining.

Bend your two paperclips to create the structure shown below:

Tape a paper clip to the positive end of battery C. Make sure the larger loop goes around the bulge and secure with tape. Attach the other paper clip to the negative end in the same way. Glue these in place.

Open a book and balance the battery pack on the folds with the axle holders facing up. Place three small neodymium magnets one on top of the other in the middle of the battery. Insert the shaft ends into the loop handle. Let the engine run!
