I gathered a number of items from around the houseand put them all into a ziploc bag with a flashlight. Thenbefore letting the kids sort, I made sure they saw examplesand understood the difference between something thatwas transparent: you can see obects clearly through and light passes throughtranslucent: you cannot clearly see objects, but light passes throughopaque: light does not pass through I was surprised by a number of objects...

I have lots of science experiments that we didn’tget to this past month. Since we’re going on toother units, I didn’t want to do science experimentsdaily. Instead, I have decided to set up a new sciencecenter every Monday. That gives me time over theweekend to gather the materials I need and to getthings set up. On Thursdays, I plan to set up an “old” experimentthat we’ve done already out on...

Part III: Float a Penny Test how many pennies can be placed on an index cardbefore it sinks. Do the same with a popsicle stick. See how many rocks/pennies can be placed on a pieceof bark before it sinks or tips over. Part IV: Float AND SinkTry to make the following items float. Then try to makethat same object sink. Do not place anything on it. Try: aluminium foilclaya plastic...

By the way, I read that you can freeze the red cabbage juice and then thaw it to use later.

This simple experiment is courtesy of a goodfriend of ours (thanks Mr. M!). All you needis a very strong (earth) magnet, a copper wireand a battery. The wire doesn’t need to touchthe magnet at the bottom, it just needs to beclose. The wire will spin very quickly aroundthe battery (and will get quite warm to thetouch, which also fascinated the kids). The kids thought it was interesting that ifthey flipped...

We actually do this experiment fairly frequently. Wefirst did this last January. Then we made volcanoes againfor our Natural Disasters unit (when we studied hurricanes,volcanoes, tornadoes, tsunamis and things like that). Wehad the perfect opportunity to do this experiment againalong with the Bubble Bombs when a friend was over fora play this afternoon. I’m sure you know how, but if not: A few days ago, we made the volcano from...

The kids had a lot of fun with this experimentas well. 1) Add vinegar to the bottom of a ziploc bag.Ours happened to be red because of the volcanobut plain vinegar is fine.2) Place baking soda into a tissue, wrap it upand hold it near the top while sealing the bag.3) Mix the baking soda and vinegar, drop andrun.4) The bag will POP much to the delight ofthe kids!

Today’s experiments (8 & 9) both investigated surfacetension. In this milk experiment, we watched as dish washingsoap broke the surface tension of the milk and sent dyeracing away. So, here’s what we did:1) Pour a small pitcher of milk onto a plate2) Place 1 drop of each color — red, yellow, blue and green3) Dip a Q-tip into dish washing soap 4) Place the Q-tip gently in the center of...

Now you can continue altering the surface tension, dippingthe dish-soap covered Q-tip in various spots in the milk.
