Tranist of a Planet Tranist of a Planet Dear all, I wish to create a model, for my students, to measure the decrease in light as a result of an object moving in front of a light source. The idea is to simulate a transit and to calculate the relationship between the object size and the light curve. Any help will be appreciated.

Bioengineering Organs Bioengineering Organs Hi, I am doing a project related to "Creating a Kidney: How Stem Cells Might Be Used to Bioengineer a Vital Organ" except I am doing it on bioengineering lungs. I am wondering how I could find research papers that would explain the different soluble factors used to differentiate lung cells, like how it is shown in table 1 of the procedures. I have tried using the websites suggested but I do not understand how to specifically look for these… Read more

Bioengineering Organs Bioengineering Organs Hi, I am doing a project relating to "Creating a Kidney: How Stem Cells Might Be Used to Bioengineer a Vital Organ". In the Make It Your Own section it said that there are many other organs that can be bioengineered. I am planning to make this project about lungs, but I am having a hard time finding out what cell types I am doing the research on. For example, the kidney has a main filtering system called the nephrons and the nephrons have two main… Read more

Arrhenius equation and crickets

Ask an Expert Topic Forum: Grades 9-12: Life, Earth, and Social Sciences

Arrhenius equation and crickets Arrhenius equation and crickets I am working on a project to test the accuracy of cricket chirps to determine the temperature. Equations are listed in the farmers' almanac that can be used, but I also wanted to test the accuracy of those equations versus the Arrhenius equation since it has both constant and exponential factors. My issue is that I am having difficulty deciding what factors to use in place of my variables in the Arrhenius equation. Factors that… Read more

Finding materials

Ask an Expert Topic Forum: Grades 6-8: Physical Science

Finding materials Finding materials I’m doing the experiment “Materials for Sound Barriers” and I have a pretty good procedure in mind but I can’t think of how I should do the actual box. I was planning on getting cardboard boxes and lining the boxes with the different materials on the inside of the box, but that would make it harder to use some of the materials I planned like glass. I am also indecisive as to whether the control should be just the cardboard (but thicker so that the… Read more

engineering a cell phone stand engineering a cell phone stand Students picked this topic for the science fair and I am struggling with a question, ID and VD. Can someone please give me some ideas? Re: engineering a cell phone stand Hi - this project is better categorized as an engineering design project instead of a scientific method project. The process for each is different - we have a resource comparing them here:… Read more

Designing a helping hand

Designing a helping hand Designing a helping hand My student picked building a helping hand as a science project, but there is no experimental procedure. I am unsure how to help her construct this project. If there somewhere that I can be directed to or some pointers on how to get started Re: Designing a helping hand Hi - are you referring to the Science Buddies project or did your student pick this project separately from our website? We have a robotic hand project with instructions here:… Read more

Doppler effect

Ask an Expert Topic Forum: Grades 9-12: Physical Science

Doppler effect Doppler effect Hello! I want to conduct an experiment on Doppler effect in circular motion (with sound source moving in a circle and a stationary microphone recording) and to explore the dependency of initial frequency over the observed one, however, I'm afraid it won't be difficult enough. How do you think I can improve the experiment and question to make it more complex? Thank you! Re: Doppler effect phys_stud - I think this experiment can/will be extremely difficult! … Read more
