Science Corner: Impromptu Nature Study

We live in a very big city, that's full of people, cars and buildings, which leaves little room for wide open spaces to view nature. Our parks, which are few and far between, are more concrete than grass. So needless to say that our nature studies have not flourished. This year I have felt the challenge to discover nature where we are at.


I have been growing an herb garden so that I can have some of the herbs that I am accustomed to. Let me first say that I don't have a green thumb, so we have had a few discussion on the many ways that mommy can kill a plant! Recently my majoram plant was returned from my friend the herb doctor who managed to save it for me. While it was at thier house, it began to bloom. I was disappointed because now I won't get as many leaves from it, but glad because at least he was able to revive it! What I didn't realize is that the flowers on my plant would attract butterflies all the way up to the sixth floor. We've had a great time observing the butterflies from our window, talking about how they eat, how we know their butterflies and looking them up online. I really couldn't have planned this one if I tried!



Another impromptu nature moment came from our vegetable bin. Apparently the conditions were right for my carrot to sprout, so I cut off the top and put it in a bowl with some water. Then I used the rest for Thai Chicken Wraps (super yummy!). A few days later my daugther reminded me that our carrot was growing and it should be planted, so we did. I'm not sure how this will work as I've never grown carrots, but so far it's been a lesson about where our food comes from and how there really is nature all around us.


Hope that this weeks Science Corner inspires you to look for nature study wherever you are!

Science Corner: Experiments, but I don't have everything I need...

...so I can't do the experiment, right? It happens to me all the time, I forget to look ahead in my plans and so I didn't get all the materials I needed for the experiment we are suppose to do. (I know that I'm not the one one this happens to!) So do we ditch the experiment all together, pushing it back till another week that probably will never come?

Heaven's no! As the Super Slueths do, we think, think, think. Here are some helpful hints for doing experiments with what you have on hand...

1. See if you can substitute an ingredient: For example if the experiment calls for vinegar, try lemon juice. If you don't have a potato for your starch test experiment, try using a piece of bread or cooked pasta. For baking soda, well there just is no substitute for baking soda that I know of :). The internet and your cookbook are great places to look for "recipe" substitutions.
   
2. See if you can substitute a material: For example, I use my meat thermometer for all our experiments. Don't laugh, there's no need to go out and buy thermometers for you to use in science when you have two of them sitting in your kitchen. I have used my oven and a heat lamp (they look like fans here) for the Sun. We don't get too many sunny days here, so when our experiments have called for the Sun, I've had to improvise! If you don't have a two liter bottle, make a mini-experiment using a one liter. The list can go on and on, but the basic idea is that you don't have to have the exact item, just something close to it :).


3. See if you can subsitute the experiment: Take a look at your experiment book. They usually have several experiments for any given topic. If you don't have the supplies for the one that was scheduled and you can't make a substitution to make it work, go ahead and change the whole experiment. Your kids will still learn about science!

Hope that these tips give you some ideas about how you can continue to share hands on science with you kids even if you don't have all the materials. Trust me, it's worth the time and effort!

Science Corner: What about experiments?

Experiments take time and preparation. You have to make sure you have the supplies. You need to read ahead to make sure you know the science behind it. You have to be willing to answer the questions that will inevitable come up. So is it worth doing experiments with your elementary age student?

Most definately YES! Experiments are the best way for your student to learn the principles of science in a fun and enjoyable way. Experiments make science an exiciting adventure. It's a sneaky way of teaching your student the principles of science and it's definately worth the time and effort you put in.

So how do you go about adding experiments to your week?

I highly recommend any book by Janice VanCleave! She uses common household items for her experiments and gives thorough explanations of the science behind them. She has books for every discipline of science and most are available at your local library. Add in some living books about the topic you are studying and you've got a complete science curriculum free from the library.

If you don't want to do the planning yourself, find a curriculum that does it for you. Elemental Science offers plans that include reading schedules, narrations, experiments and ongoing projects. Biology for the Grammar Stage was what sparked my own daughter enthusiasm for science. Although I believe Elemental Science offers the best, it's not the only program to include frequent experimentation. You could also check out NOEO and Real Science by Pandia Press.

The main goal of science in the elementary age is to get your student interested and excited about science. They will learn far more about Newton's law through experimentation than they ever would by reading a book. So get up, get yourself an experiment book and start learning!

Weekly science experiment...

This week experiment can be found through this link http://www.kids-science-experiments.com/spinningball.html. It will help you to see how you can defy the laws of gravity.

First talk about forces, especially gravity and centripital force, as these are the two forces you will be working with. You could also read about forces from a book from the library. Then get the ball and jar and put the ball inside the upside down jar and slide it to the edge of the table, which way does the ball fall? Ask, what force is at work here? Next, follow the directions for the experiment found in the link. What happens to the ball now? Ask, what force is at work this time? Hope you enjoy!
