I taught Physics to high school students and undergraduate non-science majors.
High school students don't have the base knowledge to understand modern physics. It is simply impossible. You can't have any real understanding
of even basic classical Physics or chemistry without understanding calculus.
And yet we teach high school kids how to use Newton's laws to make predictions. They can then do the experiments themselves and check the actual measurements. These kids are taking the very first steps towards understanding how Physics works, and they are learning to confirm theory with experiment.
However we do the calculus for them. We give the students the equation D = V0t * 0.5at^2. But we don't explain that this is a derivative because they haven't developed the mathematical skills yet to understand what a derivative is. I had some very smart high school students come and ask where that equation came from... and I explained it. They will get a deeper understanding when they work through the mathematics for themselves.
When you are thinking about education
you are thinking about the needs of the student for their current level of knowledge.
This doesn't count as lying.
