Invertebrates are animals that do not have a backbone or a spinal column. They make up about 97% of all animal species on Earth. Examples of invertebrates include insects, spiders, worms, and jellyfish.
Vertebrates, on the other hand, are animals that have a backbone or a spinal column. They make up about 3% of all animal species on Earth. Examples of vertebrates include mammals, birds, reptiles, amphibians, and fish.
Now, let’s move on to the main activity. We will be using a PowerPoint presentation and watching some videos to learn more about invertebrates and vertebrates. The videos can be found at the following links: - https://www.youtube.com/watch?v=Sr_T4skBYNo - https://www.youtube.com/watch?v=R50Xc1EUHwg
After watching the videos, we will be doing a hands-on activity. High-achieving and middle-achieving students will be cutting and sticking pictures of animals onto a worksheet. They will then need to split the animals into vertebrates and invertebrates and write an explanation in their exercise books. This will help them practice categorizing animals based on their skeletal structure.
For the lower-achieving students, they will also be cutting and sticking pictures of animals onto the worksheet. However, they will only need to split the animals into vertebrates and invertebrates. This activity will still help them practice categorization skills.
The resources you will need for this lesson are the PowerPoint presentation, the x-ray worksheet, and the students’ exercise books.
Now, let’s see if any of you already know what invertebrate and vertebrate mean. Raise your hand if you have an idea.
