Love your question. What I've been taught that makes Science Exciting is by following the 5E Model of Lesson Planning. The five E's standing for, Engagement, Exploration, Explanation, Expansion (or Elaboration, Extension), and Evaluation, introduces a foreign science concept and eases its way into the students through interactive and certainly scintillating means. The Engagement Phase involves relating everyday themes to the topic, maybe involving a discrepant event (demonstrating an experiment that essentially breaks down preconceived notions, eliciting unexpected results), or an engaging question. It allows the students to think, and provides a great way to transition into the Exploration Phase, in which the students are carrying out the experiment itself. Allow the students to interact with tangible objects, communicating with their peers and test out certain variables, perform experiments, run trials, etc. These are the hands-on activities that really get students moving, not only their bodies (sometimes) but their minds, most importantly! This model really allows them to think like scientists. The rest of the three phases come after or are embedded in the exploration phase. But the first two phases really capture the students attention, no matter how abstract, boring, or hard the science theme.
Here is a website that may help summarize the phases tersely: https://wehavekids.com/education/How-to-create-a-5-E-Lesson-Plan
Hope this helps in the least!
