Discussion for Onion Cells Lab
Terra Kirsch (Teacher (K-12))
This lesson applies investigation to an easy to grasp concept. What a great application using the scientific method and incorporation of math to a real world situation and brining the investigation into the lab. Incorporating web 2.0 tools to relate results is a nice way for students to collaborate and share information. I wonder if students could use a tutorial on how to add data tables to a blog and review positioning and captions.
Tara Swanepoel (Student)
Great hands-on science lesson. Conducting experiments is a great way to hold student interest. The idea of posting the results to a blog is a great way for the students to practice technical or scientific writing. It should also be a motivation to do their best since their audience will theoretically be the whole world.
I did wonder if the lab, perhaps, also focused on how salt solutions keep the roads from icing over. It wasn't directly mentioned in the lesson plan, but it was alluded to in the section about motivation under the sub-heading "meaningfullness."
No technical issues.

Great lab and wonderul use of the UDL principles. You were able to create a hand-on lab experience while integrating technology! I like the idea of giving the children a real world problem and allowing them to investigate it using another material (i.e. seeing the effects on plants by studying the onion). I might suggest that you pair the stronger students with the struggling students as opposed to allowing them to choose their own groups, this is a lab that could benefit from teacher guided pairing.
No technical difficulties encountered.
