They would teach whatever science they have that shows the Bible is true. For example, the Bible says "In the Beginning" Science also says there is a beginning. So they would teach what science says about a beginning. The Bible talks about "heaven and earth" So in a science class they can talk about what science has to say about a heaven and earth. The first three heavens is the atmosphere around the earth. Science has a lot to say about our atmosphere and science has a lot to say about the earth we live on.
Genesis 1:2
And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.
"Without form and void" means desolate and empty". According to GAP this means that disaster is upon the earth and there is a destruction. The study of volcanos and esp super volcanos is a good example of how there can be "darkness" upon the earth.
This verse could also be used to describe when the what they call the snowball earth. In that case the ocean would be covered with water.
So you could talk about how the ice began to melt and how land and water began to form under the ice or snow.
We know and understand more about creation and science can be used to help us to better understand our Bible.
In fact in Bible school they teach us some different ways to use science to help us to teach the Bible. For example the Bible talks about how we can be pure before God. Science has a lot to say about purity. The Bible talks about how fire can be used to purify. Science talks about how you can purify metal in fire.
The Bible talks about cleaning your garment. Science can show us about garments and how to clean them. So science can be used in a lot of different ways to teach the Bible.
