During our parent-teacher conference day, I took some time to plan out my Science-making it easier for me to teach the same thing three times and making sure the kids had consistent information!
I introduced them to the topic by doing a thinking strategy-Zooming In.
I took pictures of rocks that had been weathered, and cropped and zoomed a tiny piece. We talked about what they thought it was and why before showing the 'full' picture.
|I tried to show different examples for the different kinds of weathering-and I had to stick in the Old Man in the Mountain-a New England favorite (although his face fell off in 2003!)|
skittles lab-to simulate weathering, as well as a soil lab-to simulate erosion.
For our skittles lab, we use skittles, vinegar (chemical weathering) and water (physical weathering) to slowly wear away the skittle. Kids love seeing what happens!
I have everything set up on trays before hand, and students work in partners.
Or a glacier
|We had 'fake' glaciers-the ice would have melted before we did the lab!|
And water-which I set up a little differently (and emphasize that the color change, nor the dact that turns to mud are acceptable answers on why it erodes!) so they can really see what happens.
|I have them suction out the excess water so they can see what the water did!|
Then, we test! Students do get to use the model that we drew at the beginning of the unit. Overall, they do a very nice job, and they love the hands on part of it.
Now we shift to states of matter-another fun topic!
