Question: Can you help me find interesting topics for a science exit project?

i dont want topics for an experiment, i want topics for example, like the human body or something. I want to do something very interesting that will “wo” my teachers, but nothing seems to come to mind. I need a topic i can do a creative board on, and be able to write a 5 to 10 page report on the topic…I NEED HELP ASAP
the project topic outline and idead is due on WEDNESDAY

Answer: The human genome.

Question: Quantum Physics. Does the observer really change everything?

I suspect there is some pop science crap that says the experiment sences you are there. there is some very well produced high production value documentaries trying to pawn this off. however a short definition I read say the quantum physics can only be measured by bouncing a partcle off of an electron. that slows the electron and the observation is tainted. it that more accurate or am I lost in the woods on this one?

Answer: Yes, in quantum physics that is true. To measure something, you impinge photons (light packets) on the object being measured which alters the momentum and properties of that which is being observed. So the observer adds uncertainty to the measurement. Things can even get weirder with the particle wave duality where we can never observe a particle acting simultaneously as a particle and a wave, but if we design and carry out an experiment to test for wave properties we observe it, then can see the same object acting as a particle (and not as a wave) further down the experiment hall. Quantum physics is either awesome or the bane of man, depending upon your perspective..

What is Fossilization?The definition of fossilization is the process of conversion of matters into fossils. There are many types of fossils resulting from different types of fossilization process. 

Fossils come in many different varieties. Each type of fossil is the result of a different fossilization process, and each tells paleontologists something unique about the material preserved. 

Who are paleontologists?

paleontologists are scientists who study fossils and fossilization 

In this Fossilization Experiment science project you will replicate five different types of fossilization and learn why each type of fossilization is important.
