Are you an independent, self-directed learner? That is one of the goals for my students this year. And I was so impressed last week to see that many of the students in my science and math classes are stepping up to this challenge.
Here is one example that was really amazing. During my prep period I was working on getting [...]

So many people have misconceptions when it comes to science! In our class this week we explored a question that most people would think was common sense. What happens to the temperature if you fan a thermometer. Armed with our trusty lab notebooks and the scientific method we explored the question. I think most students [...]

What is causing the pressure to rise in this graph from Tina and Colette’s group? Is the pressure rising because progress reports go home next week? No. That’s not it!
Boyle’s law would help to explain what is happening. As the volume of air in the syringe was decreased, the pressure continued to increase. The molecules of gas [...]

Well, it sure beats dieting! Mike’s ingenious experiment confirms it! Objects weigh less when they are submerged in water! We used the Pasco force sensor to measure the weight of an object above the water and again after it had been submerged. Here is a challenge for you. Can you explain why the object weighs [...]

Mrs. Ford was correct! The mystery subject from the 10/26/08 post is a close-up of a fly eye! Great guesses everyone! Flies have compound eyes. Click here to read more!
This is the fly that was annoying everyone in class on Friday and Derrek rescued us from his unrelenting attacks! If you have something you would like [...]

What did I learn from my students today? I learned who is afraid of spiders and who is not! Here is a picture of Fuzz Head who was found lurking in the hallways before school. I was called in to capture poor Fuzz Head and rescue him from a screaming teacher and students who were [...]

What is invisible but has the power to crush an aluminum can right before our eyes? Watch our movie to find out! We saw how strong atomospheric pressure really is. When the pressure inside a can is reduced, the force of the atmosphere around us can easily squash the can.
Sometimes things we can’t see can be [...]

Everyone in class assumed that 50 + 50 would equal 100 but that wasn’t the case! When we mixed 50 mL of water with 50 mL of Isopropanol we ended up with 98 mL. This is more than a lesson about molecules and the space they fill…in science we have to learn to ignore our [...]

Molecular models from science class – Can you identify these models?
We have been working with the molecular model kits in class. I am always amazed and how quickly the students learn to put the atoms together and draw the formulas. Now, as we do some chemistry labs, we will see how the atoms of different [...]
