Tell me about the last science experiment

you recently did.......

I think we haven't done any in awhile...I think we mostly watch them on The Happy Scientist and Youtube....

 

The only one I can honestly think of is the extraction of the DNA of a banana.

 

That was awhile back. I feel bad. I think during Christmas "break" we will finally

do some science experiments...so lead me to some.

Please also list information where you got the experiment and resources you used to do the experiment ie name of kit, where you bought it, price.

We've done three recently. We studied relative motion and how it helped Galileo to prove the Copernican theory using a bowl of water and a ball. DS is currently working on moon charting, too, and using that data to make predictions about the coming months/researching how ancient civilizations used the moon patterns. And he just finished temperature charting for two weeks - 6 times a day, learning to use raw data to make a prediction or seeing it all come together as a whole in a finished chart.

First, I must say that I love the Science Wiz kits, because my 7 year old can do much of it himself. So I have the light and physics kits (magnets and something else are Christmas presents this year... bought them in June, so I can't remember :lol:). He pulls them out at times and does an experiment or two.

 

Other than that, several weeks ago, I had him pick out an experiment at the beginning of the week, and said I'd get the supplies for that Friday. Well, something came up that Friday and we didn't get to it. Funny thing is, he picked an amazingly easy experiment that we already had everything for! He used van Cleave's Astronomy book and did the "Red Spot" experiment. All you do is take a large jar (I used a pickle jar from Sam's), fill it with water, dump the contents of a tea bag in there, and use a pencil (we used a screwdriver) to swirl it around. It makes a whirlpool. I remembered the experiment this week and suggested they do it. The kids had fun with this and again, they could do it THEMSELVES.

 

If your kids are young, don't worry about the science experiments if you don't get to them. If they're old enough to do the experiments themselves, just have them tell you what supplies they need ahead of time, and let them do things themselves. I think they'll learn a lot more than if you're doing the experiment with them watching. :)

We use BFSU, so our experiements are pretty simple. Last week we learned about evaporation and consdensation, and talked about how air particles go into and out of the air. We used a glass of ice water, and did a couple of experiments with wet paper towels and other things to test how water evaporates faster.

 

The week before that, we did a couple of experiments to learn about mixtures and chemical reactions. We put a candle in the middle of a bowl with water, and then we covered it with a jar to watch the candle get snuffed out. This was to learn that burning requires oxygen, that the candle went out after all of the oxygen was used up, and about how the air is a mixure of different gas particles. We also did an experiment mixing baking soda with vinegar in the jar. Carbon dioxide filled up the jar, and then we tipped the jar over to pour the CO2 gas over the burning candle, which snuffed out the candle. We learned that CO2 is a gas in the air and properties about that. It was a very cool experiment. So simple, too!

Mold - We are growing mold on bread, LOL

 

We will go slightly beyond the mold experience and growth by actually making a slide and investigating it microscopically. I like ES.

 

We do about an experiment/project each week. We are rather slow at times and still in the first unit. I tend to let deviations run their course too.

We tested food for starch content by putting a drop of iodine on it. If the iodine turns blue-black, the food has starch. It was a good Thanksgiving lab!

 

We also made natural dyes from food and dyed some string, but I'm not sure if that counts as science. Maybe it's more of an art project. It was fun, though.

We did this, too - the RS4K chemistry Ch. 8 experiment. It was a huge hit!! My DD5 was around while we were working on it, and now she wants to "do science" too!

We have been growing mold. We made several boxes with food stuff in it, eg bread (both dry and damp), several types of fruit, several types of meat, leftover food, egg salad.

 

It has been sitting there for two weeks now and everything looks 'interesting' (covered with white and green mold) EXCEPT the egg salad :001_huh:. The egg salad looks exactly the same as when I bought it. Which is totally FREAKING ME OUT, considering how much egg salad I have eaten the last two months since I re-introduced eggs in my diet. I'm not sure I'm going to eat that again.....
