This experiment is a great way for you to introduce the three types of rocks to your students. I usually teach characteristics first, and use this activity is an excellent way to transition into the three types.
It first allows students to observe two groups of rocks. I usually use real rock sets in my classroom, but I have included pictures of rocks in this product as well (8 of each type) in case you do not have real rocks. The students lead the way, comparing and contrasting the two set's characteristics.
This activity then leads them through researching the three types of rocks. Fact are provided on the worksheet here, but I also let them use their books and the internet as well.
At the end of the experiment they make a hypothesis as to what type of rock are in their sets.
This experiment should be simple for you, as the teacher, because it requires very little set up, and the students can work independently as the activity is self guided. This is a simple, yet fun and hands-on way to let your students explore and lead their own learning of the three types of rocks.
