Question: What environment do crystals grow best in?

We did an experiment in science where we grew crystals, and mine barely grew compared to everyone else’s and it was under the heat lamp like theirs was. Why is this?!? URGENT!

Answer: Though it does somewhat depend on what type of crystal you are trying to grow, hot, and somewhat humid conditions will help your crystal to grow best. Also, make sure it won’t be in a place with any vibration, as it can dramatically slow and even stop a crystal’s growing.

Question: what is a science experiment with a magnet?

Answer: I found you – a whole page – gives all the instructions – to perform a lot of experiments ♥

Measuring the strength of magnets – using paperclips and BBs.
1. Count how many paperclips or staples you can attach end to end from the north pole to the south pole.
2. Count how many paperclips or staples you can attach to one of the magnet’s poles.
3. Have a big pile of paperclips or staples on the table and count how many will stick to the magnet, all over its surface.
4. Have a big pile of small (1 to 4mm in diameter, or 1/32 to 1/8″ diameter) steel ball bearings or BB’s in a plastic container, and count how many will stick to the magnet after you place the magnet into the middle of the pile and try to completely cover it with the BB’s. Remove the magnet all covered with BB’s, and take it to another plastic container to pull off and count the number of BB’s that the magnet was able to attract to itself.

Question: First chemistry lab report?? help with what i should write?

We did an experiment in class about chromatography paper and now the teacher wants us to write our first lab report about it. Except im not too sure what to write since I’ve never done one before. This is the format:

Title
Objective
List of apparatus Chemicals
Method in point form
Observation / result [ best presented in a tabular form if more thank one reaction]
Discussion
Conclusion

What does all this mean whats a tabular and all that stuff. And could anyone post a link of a lab report and what it looks like.
