Science Sunday- Planting and Growing
Last week Hailey learned all about farms. So in addition to doing a bunch of crafts about farm animals we also did a few science experiments about planting and growing.
First we did an experiment to see how much water a seed needs to grow. The cup on the left was a little more than half full of water, the middle cup had just enough water to cover the seeds and the one on the right didn’t have any water. We also put saran wrap over the top of the cups to keep some moisture in.
A few days later we could see something starting to sprout from one of the beans in the cup that had only a small amount of water.
Today (6 days after we started the experiment) several of the beans are starting to sprout in the cup that had a small amount of water. We also seem to be growing some mold. The cup with no water- the beans didn’t do anything. The cup with a lot of water- 2 beans floated to the top but nothing else happened.
We also did an experiment to learn how plants get water through their root system.
We had several carnations and put them in cups with a variety of colors of food coloring mixed with water.
After about 45 minutes we could see the blue starting to show.
About 2 hours later.
The next morning the flower was nice and blue.
We made a pretty bouquet to put on the the table. The blue definitely came out the brightest.
Our last experiment:
We balanced a potato in a jar and put water in the jar. We made sure at least 1/4 of the potato was covered by the water. We started this experiment later in the week and so far nothing has happened. We should start to see some shoots growing out of the bottom sometime soon.
Oooh I haven’t sprouted a potato since the ’70s – It’s going back on my “must do” list for the kids 🙂
A great set of experiments! I love how the carnations turned out 🙂
Beautiful flowers! Such wonderful results are not the usual for science experiments!! 🙂
I’ve never seen the first one. I’ll have to add that to my ever growing list of botany experiments.
Hi — we are experimenting with seeds this week, too – that’s what my Science Sunday post is about, as well. You just reminded me to pick up some carnations at the grocery store today! Thank you!
Have a great day!

Great experiments. I am seriously inspired by all the recent “plants” posts. I need to do more with that. I know my boys would love it.
I did the same experiements – my girls loved them! I will have to try to potato one – I remeber doing that myself in school & totally forgot about it. Thanks for the reminder.
