Answer:
Below :))
Step-by-step explanation:
I would suggest having a space/rocket theme, which fits your project.
What you do really depends on how much you want to put into it.
If its a black board, you could draw/make rockets to put on the board, and some planets. You could also make/draw some baking soda and vinegar bottles/cans. From what I have done, I have pictures/writing to put on the board. I suggest priting these if you have them, and putting them around the board. You should probably put theses on first, and then draw/make things to put on the board afterward.
Hope this gives you some ideas, if not though, comment down below and I can help more!
