On this publish, I compiled a number of the greatest hands-on actions to make use of along with your children at dwelling or at college to get them enthusiastic about studying science. From making a volcanic eruption to creating slime, these science experiments for teenagers educate essential scientific ideas in an entertaining and interactive means together with ideas like engineering, aerodynamics, chemical reactions, Newton’s legal guidelines of movement, buoyancy, polymers, sound waves, and extra.
Every of those science experiments for teenagers is accompanied with a video tutorial that you would be able to watch along with your children to see how the experiment was performed and the way it works.
1. Making a Cloud in a Jar
Screenshot from Sydney Water TV video |
- Fill the jar (about three quarters) with chilly water
- Add some water and meals colouring into the small cup and blend them collectively
- Pour shaving cream on prime of the jar to make a fluffy cloud
- Use the syringe to suck the coloured water
- Slowly add colored water on prime of the shaving foam cloud and watch it rain.

The aluminium foil boat experiment is an creative twist on the traditional aluminum foil boat science mission. The target of this experiment is to assemble a ship out of aluminum foil such that it could possibly carry a set variety of pennies whereas a ball is dropped into the water from increased and better heights, leading to larger and greater waves. The purpose of this experiment is to find out how a lot the boat can face up to earlier than sinking.
Supplies:
– Aluminum foil
– Pennies or different small cash
– Ball (equivalent to a golf ball)
– Basin of water
– Measuring tape
Directions:
1. Minimize aluminum foil right into a rectangle form, guaranteeing that it’s giant sufficient to carry the specified quantity of pennies and broad sufficient to supply stability.
2. Place the aluminum foil boat into the basin of water and fill with pennies, as much as a set quantity.
3. Utilizing
the measuring tape, measure out completely different heights at which you’ll drop the ball from (begin small and work your means up).
4. Drop the ball into the water from every measured top and observe the results on the boat (the dimensions of the waves, how a lot stability it has, and so on.).
5. Report your observations in a chart or graph.
6. Repeat this course of till you attain a top that causes the aluminum foil boat to sink.

4. Sound science experiments for teenagers
On this video, Babble Dabble Do, gives 4 sensible experiments to show children about sound waves and the science of acoustics.
The primary sound experiment known as How Does Sound Transfer. Right here is the way it works: Pour water right into a bowl, hit a tuning fork, then decrease it into water. The vibrations of the fork create sound waves that switch into water making it spray.

The second experiment known as There Is a Drum in My Ear. Right here is the way it works: Cowl a bowl with plastic wrap, sprinkle rice on plastic, hit a tuning fork, contact the plastic with the vibrating fork, the sound waves from the fork making the rice soar which is how our ear drums work. The third experiment known as Stringing it alongside and the fourth experiment known as Making it Louder.
Babble Dabble Do has this superior video tutorial the place you may see the 4 sound experiments in motion.
5. Paper Airplane
Children will love making their very own paper airplane and exploring the ideas of aerodynamics. With just some easy folds, children could make their very own paper airplane and watch it soar! You’ll be able to watch this video tutorial to see the experiment in motion.
6. The Magical Floating Water Experiment
The floating water experiment is a enjoyable and academic exercise for teenagers to discover the science of buoyancy. On this experiment, children will combine completely different quantities of salt in heat colored water to check if they will make the water float on water.
They are going to use an extended cylinder, funnel and salt for various quantities of the answer. By doing so, they may study in regards to the density of various colored water and the impact that completely different quantities of salt have on it.

9. Humorous Elephant Toothpaste
The Humorous Elephant Toothpaste experiment is a enjoyable and academic science experiment that ends in an eruption of froth. It entails the decomposition of hydrogen peroxide, with yeast or potassium iodide performing as a catalyst to interrupt it down into oxygen and water. The oxygen and water then combine with the dish cleaning soap to create foam.
