12 Days of Teaching: 4 Cool Science Experiments


We kick off the second week of our “12 Days of Teaching” blog series with four cool science experiments guaranteed to promote questions and engage your students.

According to Eric Brunsell, Assistant Professor of Science Education at the University of Wisconsin, there are five key features to a good inquiry-based science experiment.

  1. The learner must engage in scientifically-oriented questions
  2. The learner gives priority to evidence in responding to questions
  3. The learner formulates explanations from evidence
  4. The learner connects explanations to scientific knowledge
  5. The learner communicates and justifies explanations

From this, we understand that science activities must focus on real world ideas—activities should be prompted from open-ended questions where multiple answers are possible. They should spark questions, and motivate students to probe further.

With this in mind, take a look at the four cool science experiments listed below, curated from the Teachers Media International (www.teachers-media.com)  library. Not only are they sensational, they’re also designed to engage student learning and provoke questions.


In this visually impressive experiment, secondary students use glowsticks to show luminescence and rates of reaction. A great complementary resource for your chemistry lessons.

Dry Ice – Exploding Bottles

Teach “sublimation” with a bang—this experiment, suitable for secondary students, reveals the explosive power of subliming dry ice.

Forces: Rocket Launch

In this “dangerous” experiment, primary students work through a series of questions to determine how much air pressure is needed to move objects of varying size.

Materials Activities 

Introduce young scientists to the subject of “changing materials” with these great experiments that use common materials such as sand and snow.
