Tyler Hollow

Welcome to Mr. Hollow’s class!

I am very excited for another year at Helena High School. This is my 7th year at HHS and each year I love my job more and more. I really enjoy the students at Helena High School and appreciate their willingness to work hard, be involved and think critically.

I teach Earth Science and Biomedical Innovations. They are both laboratory based and focused on the process of science. I am passionate about Science and am excited to work with students in the Science Technology Engineering and Math (STEM) fields. STEM currently has a lot of opportunity for our work force and has many amazing new ideas that HHS students will be a part.

For Biomedical Innovation student’s class material can be found on the LMS link.

Please view Earth Science syllabus and course outline. Semester test reviews are included in this area.

Science Circus

Students have an opportunity to participate at Science Circus this year.  Science Circus attracts a thousand people each year to Helena High and students showcase amazing Science Phenomenon.  Earth Science students can develop their own project or assist in other for extra credit.  See material for more information.

Click Here for Nature of Science Unit

Students will apply the Metric System and Measuring to investigate scientific questions through experimental design.

Click Here for Oceanography Unit

Students will study ocean floor features by developing and using models.  Students will dive into three different types of ocean currents and learn about the  effects of El Nino and climate changes effect on density currents.

Click Here for Research and Current Event Resources

These resources will be helpful for researching Earth Science related topics.  Take some time to look at each site.

Click Here for Geologic Time Unit

Geologic Time Unit will take the students on a Journey Back into Time and investigate Relative Time, Absolute Time and the figure out how Scientists use Radiometric  Dating to create the Geologic Time Scale

Click here for Hydrology Unit

Students will explore the water cycle in depth, spending time engaging in fun activities in surface water, groundwater and glaciers.  Hydrology Unit is covered in Chapter 6 in the Earth Science text book if students need additional support.

Click here for Astronomy Unit

Astronomy is the final unit in Earth Science.  Students will explore the universe, with special attention to our solar system and Earth’s moon.  Students will also explode in to space by making their own rocket.
