I think that is better have a light materials because the space craft when is in the earth the spacecraft can't take off.

I think that the space craft don't have to have a magnetic materials, because one space rock is magnetic the space rock crash whit the space craft.

I think that the material have going to the space don't needs absorption because the spacecraft can broke

We catch one scale an put on the materia, an we can look the weigth of the material

# data[].attributes.body
We catch a magnet and whit the magnet we bring the material an will be able to see if the material closer the magnet it will be magnetic.

# data[].attributes.body
We look that the most of minerals are magnetic.

We have made an electric circuit and in the end of the circuit we have put a material so that a light put on.

# data[].attributes.body
We look that the plastic is the material that have more absorption,

1.) The plastic has a average of 0cm
2.)The wood has a average of 0cm
3.) The Aluminium has a averge of 83,3cm
4.)  The copper has a averge of 120cm
5.)The stone has averge of 130cm
6.)The brass has averge of 196cm
7.)The steel has averge of 210cm
8,)The polyester has averge of 210cm

We are measured whit a slop (slop like that a rule) on the slop and throw a marbles and crash whit the materials, and in a moment whit the marble crash look the number whit the marble arrive.
