Many (but by no means all) professional scientific organizations do have
some statement of key principles, but finding a unified trans-discipline
statement for the sciences as a whole is difficult.

However, something like that has been attempted:
Hazen, Robert M. & James Trefil. 2009. Science Matters: Achieving
Scientific Literacy. New Edition. Anchor Books. ISBN-13 978-0-307-45458-4

Each chapter has highlights of the main themes of different scientific
fields. But at this scale, paleontology (for instance) isn't big enough to
stand as its own field, but is rather reflected in geology and
evolutionary biology. Hazen & Trefil try to summarize the key theme of
each field as a bullet point: here they are, organized by chapter:

1. Two ideas:
a. The universe is regular and predictable
b. One set of laws describes all motion
2. Two ideas:
a. Energy is conserved
b. Energy always goes from more useful to less useful forms
3. Electricity and magnetism are two aspects of the same force
4. All matter is made of atoms
5. Two ideas
a. Everything?particles, energy, the rate of electron spin?comes in
discrete units
b. You can?t measure anything without changing it
6. Atoms are held together by electron glue
7. The way a material behaves depends on how its atoms are arranged
8. Nuclear energy comes from the conversion of mass
9. All matter is really just quarks and leptons
10. Stars experience a cycle of birth and death
11. The universe was born at a specific time in the past, and it has been
expanding ever since
12. Every observer sees the same laws of nature
a. For Newton, motion is along curved lines in a flat space
b. For Einstein, motion is along straight lines in a curved space
13. Earth?s surface is constantly changing, and no feature on Earth is
14. Earth operates in cycles
15. All living things are made from cells, the chemical factories of life
16. All life if based on the same genetic code
17. All life is based on the same chemistry and genetic code
18. All forms of life evolved by natural selection
19. Two ideas:
a. All life is connected
b. You can?t change just one thing in an ecosystem
