Students conducted two diffusion (The process of matter spreading out evenly from its source. An example of diffusion is when perfume is sprayed and eventually is smelled throughout a room.) experiments in their workbook.
- Smelly Balloons - Three balloons were filled with a "smelly" liquid - vanilla, lemon extract, and raspberry extract. Students then smelled the balloon. Students should have been able to smell each liquid. This demonstrates diffusion because the particles are small enough to move through the tiny holes in the balloon (from a high concentration [in the balloon] to a low concentration [outside the balloon]).
- It Reeks In Here - I used a container with chopped onions and garlic for this activity. I opened it up in front of the class. I then timed how long it took to get to the back of the classroom. Students recorded that data and graphed their results.
I began the constellations lecture. Students completed their graphic organizer during the lecture.
Students began working on the Introduction to Mars WebQuest. This will introduce Mars to the students. They will also begin learning how to observe features on the Martian surface.
