The Known Universe

For my first post I have a youtube video that ties in very well with the beginning of the space unit in grade 9 science. Students are required to understand the difference between solar systems, galaxies, and the universe. These are very abstract concepts that are hard to visualize so I am providing you with a video that starts on Earth and then zooms out slowly, identifying the different elements in space as it goes, until it shows the entire known universe. Many students are visual learners and will quickly forget things they cannot visualize so I would explain the meaning of solar system, galaxy, and universe and then show them this video to help them cement the information.

Egg Osmosis

This next video is great for the cell membrane portion of the cell unit in Biology 11. It shows an experiment with two eggs, one in a hypertonic solution and one in a hypotonic solution. This experiment is very cool and illustrates osmosis and the effects of hypertonic and hypotonic solutions on cells. I would show this video after explaining each concept and getting my class to hypothesize what the result of this experiment will be. It would be interesting to do this experiment with a class but it would take about a week to complete so using the video is a faster way to give your students a similar experience. This experiment, whether performed by the class or shown in this video, provides a real life example to a confusing and generally microscopic topic.

Hey guys! I found this super awesome game online for your students to practice their WHMIS symbols before they go into the lab. This could be a good refresher before every lab to make sure that the students remember their training.

Lab Safety Video

Continuing the WHMIS theme, here is a lab safety video by Hank Green. It is hilarious and informative. This is great to show before going in the lab for any science but it has an emphasis on chemistry.

Exam Prep

Here's a great video to help motivate your students before exams! It should work for all subjects matters so give it a try in all your classes ;)

Hands-on Activities

This website offers tons of hands-on activities for middle and high school science classrooms. Each activity comes with a student hand out and teacher preparation notes that you are able to add to and change on your computer. The topics include: human physiology, evolution and diversity, molecular biology, cell division and genetics, and introduction to biology.

Bohr Diagram Simulation - Grade 9 Science

This website has tons of resources but as an example, here is a simulation of the Bohr atomic diagram so that students can build their own atom and learn about protons, neutrons, electrons, and elements in a hands-on fashion.

Anatomy Games

This website has some great games that help students learn anatomy in an interactive way. These games are great because they go over the different body parts and test you again and again until it is cemented in your mind. I personally suggest poke-a-muscle and whack-a-bone as a fun way to spend a Friday evening.

Nervous System Models

This website has tons of different ways you can model the nervous system (especially the neuron) with your class in a fun and interactive way.
