The picture is too blurry. Should add sound to this slide to make it interesting and attract the elementary school students.
The slide is pretty good, not too much text for the students to get bored.
Don’t need to include who gave the idea that element number 31 is exist and shortened the last text. Should keep the consistency, add one more pictures and edit it. The way you organized is not really good. Write all the information in one side and show the picture in one side.
If you decide to show a video, edit it too make it interesting for the students because they will get really bored if you show the long video with a bunch of difficult words.
Even though it is for elementary students, you should add more information such as properties, but just keep it simple.
