Science Buddies: "Ask an Expert"

i am in grade 9 and i have to make a physics investigatory project on any topic. Since i have no clue how to make one , i need your help . If possible can you show me a sample investigatory project and also can you suggest me some topics.


thank you

Hi,

You should scroll to the top of the page and click on the link to Project Idea Guide.
The guide can either be used to find an idea that matches your interests, or you can prowse ideas by subject by venereal topic area, Like physics.

You should also click on the the project guide link at the top of the page to read about how to do a science fair project. If you still have questions after reading both these page links, then post back with more specific questions.

Have fun with this assignment!

Best regards,

hi

I went through both the columns and found 3 topics which i like.Can you help me in choosing 1 out of these? they are :
1.Investigating the 'Mpemba Effect': Can Hot Water Freeze Faster than Cold Water?
2.Measuring Sugar Content of a Liquid with a Laser Pointer
3.Absorption of Radiant Energy by Different Colors

thank you

Hi,

All three are good projects. You should choose the one that interests you most, qnd which you have the resources to do. Only you can make this choice.

Good luck and have fun!

Hi ,
i went through all the projects and I like the following project:
https://www.sciencebuddies.org/science- ... p056.shtml

But the problem is that I have to write the hypothesis which i am not able to even after reading it in the project guide. If possible can you help me writing the hypothesis of this project.
Please reply fast since i have to submit my project on Monday i.e 14th December.

Thank You
Eishita

Hi,

Your hypothesis is just your guess at what the answer to your question will be. In your case it could be some thing like:

“ If I measure the speed of light by c=f*wavelength, then I will find it to be x m/sec or y miles perr hour, and the wavelength will be z cm.”

You can look up what other people have measured the speed of light to be and use that for your guess, then convert that into the wave length you expect to measure, You will have to study up on unit conversions to do this.

Good luck!

Best regards,

Hi,

Thanks a lot for helping me with writing the hypothesis. My younger brother is in grade 5 and he is doing a project on the following topic:
https://www.sciencebuddies.org/science- ... p057.shtml

He wants to know wha will be the hypothesis for the above project.


Thank You

Hi,

He should read this page from the Science Bddies project Guide:

https://www.sciencebuddies.org/science- ... esis.shtml

A hypothesis is your guess ow what the answer to your question will be. It should be your guess, not mine. It does not matter if it turns out to be incorrect - that happens all the time in science experiments. In fact in successful experiments the hypothesis is often wrong when you find out surprising and important results. Your brother’s hypthesis should probably be something about which method is best for cooling soda. Use the formula on the above link, and fill in the blanks. Remember to first figure out your question, The hypothessis than is your predicted answer to that question.

Good luck to you both, amd remember to have fun doing the projects!!!

Best wishes,

hi,
Thanks with the hypothesis , my brother was able to write it but he is in a fix . He has to submit his project tomorrow and he does not know what to write in the observation and it's too late to perform the activity so i just need your help in telling me what the observation is .He knows that it was his fault not doing it it if possible can you send me a sample observation of the following project:
https://www.sciencebuddies.org/science- ... p057.shtml

PLEASE REPLY FAST

THANK YOU
EISHITA

Hi Eishita,
Unfortunately, the observations section really depends on what your brother observes himself. Although we would love to help you with any questions you have, it is not possible for us to physically DO the experiment for him...this would make it our experiment and not his. I would suggest that either he conduct as much as he can of the experiment or to try changing the topic last-minute (which would make it extremely hard). In any case, I wish him the best of luck!
