Let’s see how much you’ve picked up with these experiments and the reading – answer as best as you can. (No peeking at the answers until you’re done!) Just relax and see what jumps to mind when you read the question. You can also print these out and jot down your answers in your science notebook.

A bungee cord is like a spring, which is a linear relationship between how far you pull the spring (“x”) and the spring-constant (“k”, which is a math number calculated through experimental tests – usually comes with the product information). The spring equation is called ‘Hooke’s Law’ which is F = kx, where F = force. Note that k can change depending on the distance the spring is pulled, but usually it’s a constant number.
The inverse square law is used in gravitational fields and light intensity equations. Does that help?
If 2 people were at each end of a bungee chord, wouldn’t the force be stronger the farther away you were from the other person? Then wouldn’t it be the inverse of the inverse square law? 🙂
Yes, you should have complete access – did you login in first on the main page? You can still read some of them material without logging in.
Try that, and then go back and watch the videos – they should work. Let me know if you still have trouble…
Hi, I signed up for the preview option for the e-science program and i am just getting a chance to look at it. I went thru most of the reading but i was not able to access the experiment section. Is it that part down or not part of the access i have at this time. Thanks, Debbie
Hmm… that would be because… they aren’t there! Wow – thanks for the tip – I’ll post those right away. 🙂
I can’t print out the questions or answers either. I don’t seem to have a save as option when right clicking.
Hi Teresa,
Thank you for your kind words! Yes, I am the author of part of the program – the eScience is actually a collective collaboration from other science teachers as well. I am so glad to hear it’s working out for you. Have you had a look at the Parent Resource area? We’re going to have more articles soon about how to work with your kids by meeting them at their level and helping them expand. We’re also having bonus teleclasses on that very topic as well (check the course syllabus, too).
aurora, i can not thank you enough for this program. My son has auditory and visual processing difficulties and is in 7th grade. he is almost to grade level reading but it is very challenging to learn by textbook (not to mention how really boring learning from textbooks can be) we were going to use another program for this yr but after being in your summer camp and now seeing how this program is set up I can have him read the main point download-get into
the experiments and read the text with him if he is further interested!!! thank you too for the exercise that we can do as a discussion!!! i can not thank you enough. Your text reads more like a living book as the author is so exicted about the subject-are you the author? this all is very easy to access! you solved my dilemma for science this year but finances might not allow a whole year.It is a great value to me and all my sons. my eight yr old is still making baking soda rockets on our deck!!
Blessings
What kind of trouble are you having? If you click on the link, a small box should pop up asking where you’d like to save the file to on your computer. Try using a right click and select ‘save as’. Does that help?
Hi,
I can’t seem to print out the questions or answers. Am I missing something? Thanks, Carol

Yes, you’ll have the PDFs when we official ‘start’ on Sept. 1st.
Hi,
Is there a print friendly version of the quizzes and answers? When I try to print I’m getting the entire screen.
Thanks,
Mandy
