Question: Can you give me some steps how I can start my science experiment?

Hey Everyone!
I am doing a science project and my topic is
How does increased CO2 levels affect plant growth?
and I am not sure how I can experiment it. Can you give some steps how i can test it! and what materials will i need??
thanks!

Answer: You’ll need some plants, some dry ice, and a way to enclose the planets to make sure you can maintain the levels of CO2 they are receiving. Dry ice is solid CO2, and probably the best way to get ahold of it. Then you just have to put a few plants in different levels of CO2 and monitor their growth.

Question: Egg drop parachute ?!?

I have a science experiment to due. i have to make a container that will keep a raw egg from breaking after a 6 meter fall.

I’ve made a container for the egg. the outside is foam and the inside it stuffed with cotton balls for padding, so i don’t think it is too heavy.

The problem is. i don’t know how to make the parachute for my container. the container is a cylinder shape- 10 cm in heights and the about 7cm across. I’m planning to use a bandana and yarn to make the parachute. I just want to know:

How big should the bandana be so so it will carry the container slowly to the ground?

How many strings do i attach? how long should strings be ?

AND, what SHAPE. should the prachute be ?! Circle, rectangle, square ?!

Answer: I doubt you will need a parachute. With foam and cotton balls, you should be fine. And most bandannas allow air to go through freely, so it won’t be a good parachute material.

The Egg Drop Science Experiment

Question: What are some ideas for a relatively simple experiment related to the human body?

It’s for my Advanced Biomedical Science class. For example, my teacher mentioned previous students measuring freshman boys’ pulses when conservatively dressed girls were around and when they were not-so conservatively dressed. (obviously there was a distinct difference in pulse rates)

Answer: Sorr, no clue
