Ever wonder why it is that all kinds of insects stick to a spider’s web yet the spider moves about freely? Yeah, so did we! And in a summer filled with the study of insects and spiders, this was a perfect question to address at the McGaugh Academy this week.

And when we wonder, or want to know why and how come, it is time for a science experiment!

Courtesy of a special edition of Disney’s Family Fun magazine (currently on newsstands), I found a simple experiment, which we replicated today.

We made a web on construction paper using double-sided sticky tape. Once the tape-web was made, we put out fingers on it. Yup, stuck. We had fun doing that for awhile, and then…

We dipped our fingers in a little bowl of cooking oil. We discovered that oiled fingers can glide right over the sticky tape. Hm.

It turns out that spiders have two means of not sticking to their webs. First, not every strand of their web is sticky, and spiders have a “memory” for which strands are sticky and which are not. Second, and most germane to our experiment: spiders coat their legs in a bit of natural oil, allowing them to glide about freely.

Neat-o, huh?

To extend the lesson beyond the experiment, we used our field notebook, a.k.a. “Katie’s Nature Journal” as she wrote (with me giving her the letters, of course) on her title page. We dated the entry, she drew a picture of a spider, we answered three questions about facts we learned through our experiment, we saved a space to glue a picture of the experiment, and then we made a box in which to gather data. For our data, we chose to make a tally of how many webs we all could find in the backyard this morning. (We found eight, before Eric wanted his nap).

The little people look for spider webs this morning.

Making a tally in her field notebook/nature journal.

I am sure we’re going to get quite a bit of use out of this nature journal. It is possible to do a small entry daily, even taping in things like pretty leaves or unusual finds, or making a note about which birds we see, or if we see the Eastern Swallowtail that likes to fly through the yard. Nature is an infinite source of learning and awe. I love how we can teach our children to zoom in and pay attention to all the beautiful details, to let that awe and wonder create lasting passion in them, an endless curiosity.

We could also repeat the spider web tally monthly on the same date, and if we gathered enough data points, we could graph the results and see when spider webs are most prevalent.

Always learning is always living.

Ice on a hot summer day? Sounds great to me!

I have seen this activity on at least three different blogs this month, so I make no claims to being original with this fun lesson plan (though this write up and the objectives are my own). Still, this activity  is so easy and perfect for these last summer days that I thought I would post it and pass along the idea.

ICE EXCAVATION ACTIVITY

Objectives:

1) Students will be able to identify methods for melting ice and apply those methods in a hands-on activity.

2) Students will have a working knowledge of the terms “excavation” and “archaeologist” and “fossil record” (This seems ambitious, but Katie and I have played “archaeologist” many times since she was a little older than Eric—I would bury her toys in the sand, and she would unearth them, a favorite game we invented one day—and she knows about the importance of fossils)

MATERIALS:

Small toys

Tupperware container (with or without lid—it doesn’t matter)

Water

Salt in a bowl

Spray bottle filled with warm water

Toddler fork/scraper

The night before doing this activity, we froze small toys in a container of water. By the next morning, it was ready to go.

Katie and Eric with their tray of tools.

We talked about how the salt lowers the freezing point of the ice and how the warm water changes the temperature on the surface of the ice as well. Of course we also pointed out how doing this outside allowed the sun to help us, too!

The kiddos get to work. Katie uses the spray bottle and Eric uses his fork. (Hi Bill, yes this was highly supervised—no poking of his eyeballs!)

Eric tries the spray bottle and Katie applies some salt.

This was half-way through the excavation. Eric laughs as Katie drops the big ice block to shatter some of the ice.

I loved this activity. Both kiddos enjoyed themselves, and it was delightful to be outside. The science  (chemistry and archaeology) was straightforward, age appropriate, and fun. Katie especially loved trying out all of the tools, and we observed and felt how the ice changed on the parts where we added the salt. As a bonus, the kiddos loved playing with the ice shards after all the toys were excavated. We used the ice to write and draw on the concrete. This is an activity with mileage and natural kid-appeal: we were at it for almost forty-five minutes, and none of us tired of it. Ice excavation is definitely going to be a repeat project next summer.

I originally published this Van Gogh project experience on June 1, 2010, when Katie was two-and-a-half and Eric was still growing in my womb. I am hoping to move some of our best learning experiences over to this blog. We spent months talking about Van Gogh and looking at his work, and our studies culminated in this project. My friend Susan reports seeing similar techniques in the Usborne art book—not sure of its title, but I probably should get a copy because it sounds like something we’d enjoy in this house. We love painting with acrylics (paint clothes required!), and we had fun thickening the paints with cornstarch to give our Van Gogh painting some texture.

Van Gogh Project

“Looking at the stars always makes me dream.”

~ Vincent van Gogh

Katie and I have been studying the artwork of Vincent van Gogh for the past couple of weeks. She has been captivated by his “Bedroom at Arles” after seeing it in one of her Touch-the-Art books, and was also very familiar with “Starry Night.”

We checked some books out from the Temecula library and have spent considerable time pondering his work, mostly from his later period. We looked at several of his paintings from his time in Arles, and reflected on his life there.

Also inspiring are van Gogh’s “Wheatfield with Cypresses” and some of his other landscapes. She also loves his portraits, especially his self-portraits. Although I didn’t tell her how it came about (I think she is too young for that detail), she was fascinated that his ear was hurt and that he painted himself wearing a bandage.

As we looked at his work, we tried to note the essential characteristics of a van Gogh painting. Allowing for exceptions, we noted:

1) He mostly uses cool colors, such as blues and greens, with yellow being his primary warm color. Every once in awhile, such as in “Bedroom at Arles,” he throws in a red. Katie knows what cool and warm colors are from her art class earlier this year, and studying van Gogh is a good way to help cement that knowledge. We talked about how the cool colors make us feel, and she told me the other day that she prefers warm colors, actually (which I would have guessed). “I like warm colors better.” Her favorite color right now is red.

2) His paint is very thickly applied. You can see the brush marks and sometimes ridges of paint in his paintings.

3) His background textures are “swirly” (for lack of a better word!) You can probably picture “Starry Night”—think about all the circular motion you see in that painting. That is fairly typical, as it turns out, in his later work.

We decided to do a mimicry project based on some of van Gogh’s landscapes. (A portrait probably would have been too difficult for Mommy to draw, and although I would have loved to capture Katie’s “Bedroom at Temecula,” I wasn’t sure that would lend itself to large scale “swirlies” and thick paint application. The “Bedroom at Temecula” project might be a further study of van Gogh when Katie is older and can add another layer to her skill set and knowledge).

So a landscape it was.

We needed thick paints, and I had read somewhere that you can thicken acrylics with glue. That is probably true, but I wanted to make them really thick so I used cornstarch. That turned out to be successful. We achieved the ridgey paint marks and they were fun to use.

To test her knowledge, I put out all of our paints and had Katie choose the colors she thought van Gogh would choose. She correctly identified blue, green, yellow, and white, and then she begged to have a mix of red and dark pink for herself. We mixed those colors up with the cornstarch in separate bowls.

Then we prepared our canvas. We made a few marks to give us an outline when we painted. She helped draw the horizon, and we talked about where we wanted some clouds. She wanted a tree, and we briefly sketched one in.

Outside, we worked together to fill in the painting. She worked extensively on the grass, and was keen to do a mix of green and yellow. She also mixed the green and white herself to make a paler green. I didn’t prompt this—she likes to mix paint, and I waited for her to discover it. Then she got to put on her red and pink flowers. That was totally her idea. I think she was happier with the painting once she made it more exuberant with the warmer colors.

I did do a bit of fill-in work with the sky, but quite a bit of it is hers, and you can see that she did the clouds herself. We worked on getting the “swirly” motion into the painting. You can see it a little better close up, but for the most part it is there.

Here is our van Gogh landscape painting:

As I reflect on the lesson plan, however, I can’t help but feel that it wasn’t as solid as the Cassatt lesson. The stages and steps worked and there was evidence of learning…but as a teacher you know darn well when a lesson plan has that extra element of spark and magic and when it doesn’t. The Cassatt lesson plan connected with Katie on every level: she still talks about it. This van Gogh lesson plan was coherent, but I am dissatisfied with it on the deep level. It could be because Katie was not as big a fan of his work as she was of Mary Cassatt’s body of work. She doesn’t connect to his use of color, for one thing.

Also, some of the lesson did not meet my standards of “discovery.” I love leading Katie through discovery, and for the record, I think that is how students really learn and ought to learn…versus feeding them answers or leaving no surprises. The thrill of discovering something for yourself is the reward and motivation of learning. Anyway, I was dissatisfied with how I taught the elements of van Gogh’s texture. When it came time to identify his essential elements, I had to give her choices: does he paint with straight lines or swirly lines? Giving her an either/or is not good teaching—and I should know that by now. She learned, but it was not totally through her own discovery. With Cassatt, Katie knew so much about pastels that she was able to come up with that medium entirely on her own as we examined Cassatt’s work—that is discovery.

What I should have done was taught her more about different textures PRIOR to the lesson. Just a lesson on texture… straight lines, swirly lines, dots, etc. She of course knows different shapes, but I should have taught her some vocabulary prior to looking at the paintings, and THEN had her identify what she saw in van Gogh’s work. Instead, I tried to look at the work while teaching her the tools to look at the work. I am not sure, in this case, that that was the best practice I could have done.

I will have to make these revisions for Little Eric’s turn. 🙂

Overall, though, the learning took place (just not in as solid and authentic a way as I should have guided), and we had fun doing the project. I am thinking my next step in her art education needs to be returning to fundamentals. Maybe I should do a series of lessons on textures and the color wheel and focus on developing some vocabulary. That might be a good step before delving into another artist. She does seem to be interested in Roy Lichtenstein’s “dots” right now, though… and of course, ever since encountering him in art class, Katie has been fascinated with Andy Warhol. She loves the tomato soup can picture—probably because she recognizes it from using it in our kitchen. I saved an empty one, in case I could figure out a way to use it with her. I am waiting for inspiration to strike on that one…
