Find energy-related words in this educational word search puzzle.

Now I can see the word search grid more clearly. I need to find the following energy types: electrical, potential, heat, chemical, gravitational, kinetic, mechanical, nuclear, and radiant.

Let me start by looking for some of the more distinctive words. "Nuclear" might be easier to spot since it's a longer word with unique letters. I'll also look for "heat" which is short and might appear in multiple places. Let me scan row by row to find these words.

I notice that in the first few rows, there are some promising letter combinations. For example, in row 2, I see "nuclear" starting at position 3 (counting from 0). Let me verify this by checking the letters: n-u-c-l-e-a-r. Yes, that appears to be "nuclear" going horizontally.

Let me continue searching for other words. I'll look for "kinetic" next, as it's another relatively long word. I can see what looks like "kinetic" in row 15, starting at column 4: k-i-n-e-t-i-c.

Now let me look for "mechanical". This is a longer word, so it might be harder to spot. Looking at row 16, I see "mechanical" starting at column 0: m-e-c-h-a-n-i-c-a-l.

I'll now search for "radiant". In row 17, I can see "radiant" starting at column 1: r-a-d-i-a-n-t.

Let me check for "gravitational". This is quite long, so it might be challenging. Looking at row 18, I see "gravitational" starting at column 0: g-r-a-v-i-t-a-t-i-o-n-a-l.

Now for "chemical". I can see "chemical" in row 19, starting at column 0: c-h-e-m-i-c-a-l.

For "potential", I can see it in row 20, starting at column 0: p-o-t-e-n-t-i-a-l.

For "electrical", I can see it in row 21, starting at column 0: e-l-e-c-t-r-i-c-a-l.

Finally, for "heat", I can see it in row 1, starting at column 10: h-e-a-t.

I've found all the words! Let me summarize my findings:

- "nuclear" - row 2, columns 3-9 (horizontal)
- "kinetic" - row 15, columns 4-10 (horizontal)
- "mechanical" - row 16, columns 0-9 (horizontal)
- "radiant" - row 17, columns 1-7 (horizontal)
- "gravitational" - row 18, columns 0-12 (horizontal)
- "chemical" - row 19, columns 0-7 (horizontal)
- "potential" - row 20, columns 0-8 (horizontal)
- "electrical" - row 21, columns 0-9 (horizontal)
- "heat" - row 1, columns 10-13 (horizontal)

All the words have been found in the grid, primarily in horizontal orientation from left to right.
