Tsunami and Earthquake Hits Japan

Please click on the title above to see the videos of what is happening in Japan. Pray for those people there. You can make a difference. There are many relief organizations that are ready to help. Please support them if you can.

Protein Synthesis Skit

video

It's great to see my middle school students try to review their science concepts in a creative way.  I look forward to the next skit that the students do.

Wow, What a wild story!

Click on the title to check out the following story.  Is this natural selection at work, or just bad luck?

Evolution and Hardy Weinberg

The Hardy-Weinberg's principal in hard for students to understand, and use to make predictions about gene frequency, but the concept can be learning without even teaching students the mathematical equation, which is what i did with my 6th grade life science class.  We did two different experiments in which we simulating breeding in a population.  Students had to predict how their population would change over time, and then collect data from 5-10 generations of breeding to see if their hypothesis was correct.  After we finished, I think students understood that populations can change over time, and for different reasons, the environments, the adaptations found within the population, disease, immigration/emigration, etc.  Above are some pictures as students keep track of how many alleles were in each generation.

How Fossils Form: A Student View

video

Grade 7 Earth Science Teaches 1st Graders

One of the best ways to learn is to have the opportunity to teach someone else. Some of my students presented to the 1st grade class about how fossils were formed. After showing the student a video they made, my 7th grade class worked one on one with the 1st graders making sure they understood how fossils formed, and also letting them color some pictures of extinct animals from the Mesozoic Era.

Protein Synthesis Student Project.

My students did projects to show their understanding of protein synthesis. I will post the few that I have. Enjoy.
