- Students learn to work with others
- They practice safe working skills
- They are permitted to "experience" learning, not just see what their learning is supposed to look like.
- They learn to make mistakes and analyze them
- They develop planning, writing and critiquing skills needed for pretty much any career.
However, the main reason that you should be devoting a significant amount of your class time to labs is that it gets the students interested and engaged in the material you so badly want to convey to them! Students wont take away that amazing lecture you gave on the types of chemical reactions, but they may remember the time they mixed lead (II) iodide and potassium nitrate and saw that beautiful yellow followed by a stubborn precipitate that they couldn't extricate from the test tube.
Students love labs, they love experiencing with their own senses what they are learning in school and it really hooks them. You ask most science students what they'd rather be doing in class and they will say labs. I know this because I'm constantly being bombarded with "When will we be doing another lab?" or "Why don't we do more labs?", etc., etc.
Here's a reason to avoid those labs and I know we are all guilty of thinking it, they are difficult to mark and you already don't have enough time to mark what you have. Well that's an easy one too, who says you need to assign a formal lab report each time your kids do an experiment? Change it up.
- Setup a handout that they need to fill-in during the lab (pretty much an observation sheet).
- Have your students submit the lab but only mark one component.
- Instead of having them submit a lab, have a quiz the next day regarding specific things that happened.
There are lots of ways to reduce your marking while still providing your students with the opportunity they need. Be creative and give yourself a break.
- Make sure the lab is hands-on and allows them to find something tangible.
- Allows each group member to get involved. The worst is when there's one person who simply takes over. Assign jobs, create smaller groups, etc.
- Let your students see why/how the lab connects with the curriculum. This will increase their engagement in your lessons as they see that what they are learning has some actual real-life implications.
One lab that I love is my Eco-Bottle lab. It touches on the things I've mentioned above as it allows your students to create and carry out a hands-on, engaging experiment on how humans affect the environment. It utilizes the steps in the scientific method to scaffold learning and allows your students to come to a conclusion based on findings that are tangible. It also reduces marking by having you complete a rubric which clearly and easily breaks down the lab for both you and your students, fostering success.
