Plant Growth and Skills

Students in my middle school classroom are participating in an activity were they are growing Wisconsin Fast plants. During the seed germination part of this activity, students made daily sketches of the seeds. They labeled the radicle and cotyledons. They also labeled the seed coat and hypocotyl. Students used magnifying lens to enlarge the small cabbage seeds.

First Sunday of May

Temperatures in the 80s and partly cloudy. Just finished watching a baseball game on TV. I have been looking for some fun activities for my science classes for this coming week online. Spring time has always been a difficult time to keep students on task.

I have a lab activity that is based on Wisconsin Fast-Grow plants. I am just not sure my students will enjoy this. The activity starts with students observing germination and characteristics of seeds. Monday will be a great time to start this project. It is important that my students learn how to setup a controlled experiment. They have no idea what is meant by terms like dependent-independent variable, control group-experimental group. So, I plan to have them use this activity to learn by doing.
