Alexandra,
the ESERO Activity https://esero.ie/wp-content/uploads/2015/01/01_The-planets.pdf has no factual information, so you would have to prepare that yourself. You could start with this from Armagh Planetarium.
The ESERO activity The Eight Planets has nice worksheet structure, but expects the learners to go to books or magazines about the planets.
You might want to use this handy template from Armagh Planetarium – adapt it if you want it to be about specific planets in our solar system.
The Solar System resource from space week has options to create a scale solar system – is there a particular one you prefer? (note that these are suggested for 3rd-6th class) This will inform
Have students create a scaled model of the solar system using the provided materials.
the materials that you would have to provide. Your list of provided materials is a bit too general “planet fact cards, a scaled model or images of the planets, and interactive worksheets.“
