Elliptical orbits Formative feedback

Hi Everyone, I am sharing an elliptical orbits Formative for Earth Science: https://goformative.com/clone/OHMTPE


This looks great! I noticed for Q#1 and 2, you don’t have an answer key set. Is this own purpose? Also, are your students going to be doing their calculations on calculators? If so, I recommend embedding the Desmos 4-Function calculator: https://www.desmos.com/fourfunction


Thanks Alex- Great idea with the calculator embed!


Anytime Barry! :fist_right: (fist bump)

Hi ALex, I am not seeing the Demos embed code for the four function- are you getting it to embed with the direct web address? Thanks again for the suggestion!


Hi @BarryD

I don’t know much about the subject area, but it is nice to see that there is a variety of questions. I think you’ve provided the data that the students need, and you are asking for the answers.

What about adding a video from youtube (of course if you can find something relevant to your content here) at the beginning, so that the students who need to study one more time after the lesson feel more comfortable with your content?


Sorry about that. I took the web address and made it into an iframe using this website (https://www.iframe-generator.com/).

Here’s the iframe that I placed in my formative. I had to add a space between the “<” and “iframe” so that it would display here:

< iframe src=“https://www.desmos.com/fourfunction” style=“border:0px #ffffff none;” name=“myiFrame” scrolling=“no” frameborder=“1” marginheight=“0px” marginwidth=“0px” height=“400px” width=“600px” allowfullscreen>
