This video shows a recent eruption that occurred in Japan. I like showing this volcano video because it shows the eruption at night where you can see the lava bombs break open when they hit the ground. It also show lightning that sometimes if visible during volcano eruptions.
In this volcano video, students will be able to see a many climb up Krakatoa's child, Anak. I find this video fascinating because it vividly shows the results of recent volcanic activity. Your students will be able to witness what fine ash looks like and how fragments are ejected from the volcano. I show this video right after I show the Krakatoa The Last Days movie.
This volcanic eruption video is fantastic. A few people are on a boat when they see the eruption. What is amazing about it is the shock wave that is heard a few seconds afterward. Also you will be able to see the clouds get parted as the shock wave sores through the atmosphere. It is really a cool video to show students during you volcano unit.
In this lab students will observe the formation of salt crystals. Adding food coloring to your solution can also act as a chemical impurity so that you can have a discussion as to how minerals such as quartz get colored. Also students will see and be able to discuss mineral evaporation and precipitation.
Salt, hot plates, stirring rods, plates (preferably paper), water.
I group the students in groups of 3 to 4 as I am limited to space for the amount of plates.
Next time you are teaching your students about the scientific method, let them watch this Youtube video. The video does a great job explaining what the scientific method is by going through the different steps of asking questions, gathering information, forming a hypothesis and then stating a conclusion.
In this lab students will design an experiment that keeps to the scientific method. Students will gather data and share the experiment to the class.
When presenting, students will call on a volunteer who hasn’t ever seen the experiment before. The volunteer will perform the experiment in the fashion that was written in the presenter’s presentation.
In this lab students get together to try and discover which shoe in groups have the best rock climbing ability and then we discuss their conclusions and try to find out which person in the entire class has the best shoe for rock climbing.
Time: 55 minutes
Time will depend on how your discussion goes and whether or not the groups got into the experiment and did multiple tests.
