Experiment 13: Red Cabbage Acid-Base Tests

Yesterday we prepared our red-cabbage pH indicator. We took a red cabbage, sliced it and placed it into a pot of boiling water. The heat was turned off and we let it sit for several hours. Then we drained out the cabbage and put the cabbage juice into the fridge until we were ready to try our experiment Please like & share:

Experiment 13: Red Cabbage Indicator

Here’s the set-up of our experiment. We don’t have any test tubes, so we used small plastic cups. I also recommend having a pH indicator color chart ((I got mine from page 13 at theĀ  Surfing Scientist) as the kids really were excited to examine the chart to see whether it was an acid or a base and to decide how strong it was compared some of the other things...

Experiment 12: Make your own motor

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...

Experiment 10: The Volcano 0

Experiment 10: The Volcano

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...

Experiment 11: The Bubble Bomb

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!

Experiment 8: Fireworks in Milk (Investigating Surface Tension)

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...

Experiment 8: (cont.)

We had some really interesting movement when weadded a drop of blue and red food coloring and then leta couple drops of soap drip into the milk. The kids really, really enjoyed this experiment! I highlyrecommend this one. I’ve seen this experiment in a number of places, but there’sa good explanation of the science behind it all at:http://www.abc.net.au/science/surfingscientist/pdf/lesson_1_amazing_science.pdfon pages 6-7.

Experiment 9: Surface Tension in Water

Grandpa sent us a wonderful science video clipabout water drops. So, I set up this experiment togo along with the two minute video (which wewatched afterward). The experiment wasquite simple, but the kids were at it for at leasttwenty minutes! 1) Pour a pitcher of water into a dish2) Place some colored water into a small dish3) Using an eye dropper, pick up some coloredwater.4) Drop ONE drop into the...

Experiments 6 and 7: Magnetic and Particle Attraction

Here’s our craft table all set up with a science station. Theseexperiments have to do mostly with magnetic attraction,although we have one on particle attraction as well. I also have the magnetic maze (a gift from a formerkindergarten teacher/friend) and a craft on the milky waygalaxy. Please like & share:

Experiment 6: Particle Attraction 0

Experiment 6: Particle Attraction

This is a simple lesson that shows how particles areattracted to each other. Just have them drop paper intostill water (don’t blow or move the water around) andwatch the bits of paper move toward one another. We used bits of paper from my comb binder, but anysmall pieces should work. I’ve heard that you could alsosubstitute talcum powder or baby powder, but we did nottry this. Please like & share:
