Tyler Hollow

Welcome to Mr. Tyler Hollow’s class!

I am very excited for my ninth year at Helena High School. I really enjoy the students at Helena High School and appreciate their willingness to work hard and be involved. I grew up in Helena. I attended the College of Idaho and earned a Biology degree, then I worked in Idaho, Wyoming and Victor, Montana before moving back to my hometown. I recently graduated with a Masters in Science Teaching from Montana State University.

I teach Earth Science and Biomed 4. Biomed 4 is an upper level research class in Health Career Pathway. They are both laboratory-based and focused on the process of science. I am passionate about science and excited to work with students in Science Technology Engineering and Math (STEM) fields. Students will be thinking like Scientists and doing Scientific work every day.

For Biomed 4 student’s class material can be found on the LMS link.

Please view Earth Science syllabus and course outline. Helpful resources for student life will also be placed here.

Science Circus

Students have an opportunity to participate at Science Circus this year.  Science Circus attracts over a thousand people each year to Helena High and students showcase amazing Science phenomenon.  Earth Science students will develop their own project in class for a project grade.  They will also be given the opportunity to present their project at Science Circus for extra credit.  See documents for more information.

Click Here for Research and Current Event Resources

Here you will find great articles to read for completing an Earth Science current event.  These resources will also be helpful for researching Earth Science related topics for projects during the year.

Click Here for Nature of Science Unit

Students will engage in Science and Engineering Practices so they think like scientists and work like scientists.  Student will apply the Metric System and Measuring to investigate scientific questions through experimental design.
