Living? Nonliving? Dormant? Dead? Even though teaching living vs. nonliving seems very elementary, you’d be surprised by how often high school students get confused when you throw examples at them. It makes me think of this 90’s “J-E-L-L-O it’s alive!” commercial:
But in all seriousness….
Teaching characteristics of life is a great way to start off the year in biology. I like teaching it week 1 because it’s more fun than the scientific method (which they should know by now anyway) and a great introduction to biology- the study of living things.
Here are a few resources you can add to your teacher toolkit for your life unit:
1. Great to catch their interest: sometimes called “sewer lice” or “dancing raisins” lab, this activity gets students thinking about what really makes things living or not. Download it free here
from Flinn Scientific.
2. Check out this youtube clip that introduces characteristics of living things. Great to get them thinking!
3. Another fun question to throw at them- are seeds alive? Ask students if they think popcorn kernels are alive. If so, how could we test it? Your students will be amazed after a week once they have corn plants sprouting in their cups!
5. Try this Characteristics of Life Lab
. In this activity, students will be given a box of objects and have to classify them as living, nonliving, dormant, or dead. They will also need to find ways to test if they are living or not. For example, if they say a leaf is living, how can they prove it? I like doing this lab before
I review the characteristics of life, because it allows students to try and come up with the list of characteristics on their own. You can check it out in my TpT store here
6. I also have a set of task cards in my TpT store, where students have to identify the 8 characteristics. This is a great follow up to your lesson and good review before a quiz. Check it out here
7. Here is a free lab where students test if yeast is alive or not.
8. When we introduce the characteristics of life, we introduce the word “homeostasis” for the first time. I found that students would memorize it for a quiz and then forget it. When we circled back around to cells and discussed osmosis they completely forgot the word. SO…. I hit homeostasis a little harder by creating this station lab
. There are 10 engaging stations students will rotate through and learn about real-world examples of homeostasis in plants and animals.
I hope those are helpful! Any other great ways you teach the characteristics of life? Drop them in the comments!
