This week we continued our unit about how water shapes the earth’s surface. Our third lesson was called, “What’s strong enough to make a canyon?” Through a hands-on activity we saw evidence of how water is strong enough to carry rocks, sand, and dirt, and leave behind landforms like canyons.
Here’s something you can do to encourage your child’s curiosity: Help them look for signs of erosion on a small scale in the neighborhood. Gutters and ditches are great places to find examples of tiny canyons that have been carved out by water. Go for an "erosion" walk after it rains. Any place where there is soil or sand is a good place to look.
