Whoa - that looks interesting. These are the 16cm long pencils being used. He found the relationship to be: The class had a lively discussion the next day -- a discussion that wouldn't have happened so readily earlier in the year while the class was more answer-focused, while the class was less confident in the difference between acceleration and velocity.
This is similar situation to a baseball bat, a kitchen knife and so on which are also not weapons unless used for a behavioural offence. A mangonel does not release its energy in a linear fashion. To assist you in your planning you should think through the questions included on the 'Investigation Planner'.
This suggests a good EEI. This happened to me when I was taking apart a camera flash. These are commonly available in high school laboratories these days Vernier, DataLogger Pro etc.
Then fill it with Play Doh and poke electrodes in the ends. For a flow of water as in the diagram above, the radius of the hydraulic jump Rj is related to a number of factors and exploring these would make a great EEI.
I connected it to a multimeter set to measure resistance. If you do the preparation properly, you could get away with one microohmeter for a week if you have say 40 students, but be prepared to work before school and at lunch. However, not far behind were water clocks.
There is a great paper on this experiment by Prof. The mere existence of an equilibrium temperature Teq above room temperature is related to the existence of a flow.
In an EEI you would have to look at resistivity, temperature coefficients of resistance and why - at an atomic level - resistance changes.
It was first manufactured in Cincinnati, Ohio, U. If you do the preparation properly, you could get away with one microohmeter for a week if you have say 40 students, but be prepared to work before school and at lunch.
By measuring the volume of water collected in a given time for a Physics open ended investigation pressure and tube diameter and thickness you can look at relationships.
It would also be interesting to see the effect of light of different wavelength to see if the solar cells are sensitive to all wavelengths. If you are really keen you could do the two bottle experiment as shown below.
I also have black tiles but have a good 50mm gap between roof and panels so it should have reasonable airflow. But, if you were doing this for 3rd Year Physics or engineering at uni you'd then do a Fourier analysis to work out harmonics and so on. In terms of ruggedness, if it was onto grass a bit of foam padding may help.
The UPside -- and it's a pretty important upside -- is that the investigations themselves include lots of excellent lab ideas from really good physics teachers.
Among the various types of catapult, the trebuchet was the most accurate and among the most efficient in terms of transferring the stored energy to the projectile.
Then two weights and so on. Using a geometric argument no equationsdetermine the location of the nodes. Further, none of the above should be taken as a legal advice as it is merely my understanding based on a conversation with officers from the Queensland Weapons Licensing Branch. These were still in use in North Africa in the 20th century.
The kinetic energy of the target is conserved as gravitational potential energy. The altimeter's data can be downloaded via a USB connection and analysed for altitude, acceleration and velocity of rocket flight.Physics Advice about assessment instruments Extended experimental investigations: Ideas for EEIs This advice has been compiled by the QSA to help teachers plan and develop assessment.
On Burj Khalifa, world's tallest building, people say that they can actually see the curvature of the Earth. Using approximation and estimation, find out how many of those "curves" (a section of the circle) it will take to create a complete circle, that is, Earth.
For instance, if you put the end of a metal bar in a fire the rod will have a high temperature at the red hot end but the temperature will be lower at the other end close to your hand.
French scientist Guillaume Amontons (), assumed that temperature varied linearly along such the rod but Johann Lambert () found that the temperature profile along the rod declined logarithmically.

Educ. 38 View the article online for updates and enhancements. This paper investigates the respective roles of substantive and procedural understanding with regard to students' ability to carry out an open‐ended science investigation.
The research is a case study centred on an intervention in which undergraduate initial teacher training students are taught the basic building blocks of procedural understanding. Often one of the hardest things to do is deciding on what to do your open-ended investigation on.
Try and use some of your interests and hobbies to give you some ideas. You'll get a lot more out of your investigation if it could be applied to something that impacts you personally.Download
