Farm, frogs, and weather—children making connections

By Peggy Ashbrook

Posted on 2010-05-09

Children create models using paper, tape, and pipecleaners.Children playing with models of the frog lifecycle.There was a farm set on the light table and there were tadpoles in an aquarium nearby. One child (in the Green Frog class of course) was taken with the frog-to-tadpole sequence models and wanted to add them to the farm set-up. I asked, “Don’t they need some water?” and he said he would add a pond. He got blue paper, another child drew the oval pond shape, and another cut it out, each one contributing their expertise. Somehow that developed into making a model of a weather system (I missed the connection) and one child added a storm cloud, puddle, lightning, and thunder, all represented with paper shapes which they allowed me to label.

When I shared with the parents one of them replied, “I’m so glad you let me know about this! I asked my child about it at breakfast this morning, and he went into a ten minute, detailed explanation. Wish I had been there to see it—thanks for the pictures!”
Cover of April/May NSTA journal, Science and Children.Read more about connecting your students to changes in the weather in the April/May 2010 Young Children. In the Methods & Strategies column, “Making the Climate Connection,” Bruce Larson writes about beginning teaching about climate by teaching about weather and about “learning progressions”—the order in which students can best learn and understand science concepts. The column is chock full of resources for K-1, 2-3 and 4-5, as well as adult learners, with additional resources listed online.
Take a look!

Learning about the butterfly life cycle with local butterflies

By Peggy Ashbrook

Posted on 2010-05-07

This year I have challenged myself to use only local animals in the classroom, for budget and ecological reasons.
Luckily for me and my students, Cabbage White and Black Swallowtail butterflies go through their life cycle to adulthood in our area before the end of the school year and can easily be found on collard and fennel plants which wintered over (were planted in the fall and survive through the winter). I’ve also found the Cabbage White butterfly eggs on collard seedlings which I had washed thoroughly and set out in the yard.

Hoping to find a shortcut, I set out collard leaves from the grocery in a jar of water, but even though I had trimmed the stem ends, the leaves drooped from lack of water by the end of the day—not a very promising site to lay eggs! With two stands of five fennel plants each, and 3 packages of collard seedlings, I’ve been able to supply 15 classrooms with caterpillars and eggs.
Take a look…

She was repeatedly coming to the plants, landing for just a short time, then flying to another place on the fennel—I just wasn’t quick enough with the camera.

There were also aphids and another animal that is rounder with a tough exoskeleton that I haven’t been able to identify on the collard seedlings. These I washed off the leaves to leave more for the caterpillar. If I were teaching older children I would leave all the animals on the leaves and have the students research to identify them. I’m curious if the aphids, unknown round insect and the caterpillars happily co-exist or if they compete.

The caterpillar climbed high to pupate.


I brought some Cabbage white butterfly caterpillars into the house because it was due to storm the next morning and I wanted to take some to school. The next afternoon I noticed a pupa in chrysalis form on the hallway wall, almost two meters from the collard leaves. What a journey the caterpillar had made to its pupating place!

Enjoying conversation during a "group draw" of caterpillars


The children have been very excited to see, and draw butterfly eggs, and the Very Tiny Caterpillars. Many of them tell me (with wide eyes) that the caterpillar will change into a butterfly, something they have learned though reading or a television program. Now I hope that they will learn it through observations. Usually, only a few children remain interested in these relatively slow-moving animals except to comment on the poop. That observation is a good time to talk about what is alive and what is not, and how do we know, to learn what the children are thinking.

Because children do not watch the caterpillars continuously, they may not understand that the chrysalis is not a new animal but just a new form of the caterpillar that they had already seen. Even with prior experience of observing, handling, and counting Tenebrio beetles and larva (“mealworms”) which also form pupa and undergo complete metamorphosis, the children do not immediately accept this. When the butterfly emerges from its chrysalis, the children will be interested again. Butterflies can be fed with a sugar water solution for a day or two before being released. Nice to have a place to “borrow” butterfly eggs and babies; nice for the children to see them return to that place, the stand of  fennel plants in the garden.
See my February 17 and May 6, 2009, posts for more information about keeping caterpillars in the classroom.
What are the challenges your classroom has in learning about animals that change as they grow?

More oil spill resources

The massive oil spill in the Gulf of Mexico seems to be on everyone’s mind. Even some third-graders I was working with today were talking about it. The major news services are keeping us informed through web articles and photographs as well as traditional television news segments. Blogs and other news sites have current information and images. A recent post on the NSTA blog shared several oil spill resources. A few others to add to the list: EPA Response to BP Spill in the Gulf of Mexico and Google Earth Images.
SciLinks has a collection of websites on the topic of oil spills. Although these are noted for grades 9–12, many of them could be used by younger students. Teachers can also gather background information from them or to provide a context for the current events. The SciLinks collection includes sources such as

This event is being compared to other spills such as a recent on in California and the Exxon Valdez spill that happened more than 20 years ago. NOAA has created a comprehensive look at the Exxon Valdez spill in Prince William’s Oily Mess This site is designed as a classroom resource with lesson plans, inquiry activities in a real-world context, photographs, readings, and interviews with scientists.
I’ve experienced first hand how fragile our coastal ecosystems are. And I recently visited the Gulf Coast, where I was impressed with its beauty and how productive and valuable the wetlands are. This event truly scares me, with its implications for the ecology and economy of our country.

The value of resources and peers in the learning process

By Howard Wahlberg

Posted on 2010-05-04

Recently, I was searching NSTA’s archives for membership quotes.  Resources was a prominent theme; “thanks for the resources”, “I didn’t know you had such great resources”, and “where can I find resources”.  It reminded me how valuable both resources and our peers are in the learning process.
One tremendous resource NSTA provides is the National Congress on Science Education.  Comprised of one voting delegate from each of NSTA’s Chapters and Associated Groups, this national conversation on science education provides an opportunity for chapters and associated groups, the NSTA Council, the NSTA Board of Directors, and NSTA staff to collaboratively address issues and work toward strategies that will support our mission, “to promote excellence and innovation in science teaching and learning for all.”  Participants are also afforded with an opportunity to network with their peers, attend leadership seminars, and attend “issue forums” which result in the drafting of resolutions about key science education issues.
NSTA knows that budgets are tight and we also know the value of learning and collaborating with your peers. That is why we have waived the registration fee.  This event is organized by science leaders for science leaders.  I urge every Chapter and Associated Group to participate.  For more information, please click here.
The success of this blog is dependent on your participation!  And remember, I’m only a few keystrokes away at aodonnell@nsta.org.

Finding the right book for science teaching

By Peggy Ashbrook

Posted on 2010-05-04

Children look at a book and talk about what they see.There are quite a few science topics included in the books on the Association for Library Service to Children’s Young Readers list of 2010 Notable Children’s Books. Selections on the Older Readers list may be useful as well for the photographs and the background information that teachers can read and tell about, such as, Almost Astronauts: 13 Women Who Dared to Dream by Tanya Lee Stone (Candlewick 2010).
I also use the NSTA Recommends archives to begin my searches for age appropriate books for science teaching.

The Frugal Science Teacher, 6–9: Strategies and Activities

By Amy America

Posted on 2010-05-03

School budget challenges coupled with the general state of the national economy has resulted in the need for teachers to not only be prudent but also imaginative. Former NSTA president and current Science and Children editor Linda Froschauer outlines creative and inexpensive ways for sixth through ninth-grade science teachers to keep their expenses to a minimum. In her new book published by NSTA Press, The Frugal Science Teacher, 6–9: Strategies and Activities, Froschauer carefully selected NSTA Press book chapters and NSTA journal articles that suggest untapped resources for materials, ways to recycle items you already have on hand, inexpensive alternatives to costly classroom projects, and activities that require little to no funds. Until economic recovery takes a firmer hold for school districts and for us all, take a few tips from The Frugal Science Teacher, 6–9, to keep science students engaged.

Weather

Everyone talks about the weather, but the articles in this issue show students doing more than talking. Just look at the action words in the titles: blog, cruise, teach, make, watch, look, learn.
The differences between weather and climate can be challenging for younger students. The author of Making the Climate Connection suggests a “progression” topics for grades K–5 and recommends some online resources (many of which are in SciLinks). The lesson described in Dress for the Weather uses actual data to help students differentiate between weather and climate. The lesson uses the 5E learning cycle with a real-life focus.
Talk about a real-life focus—the students in the article Blogging About the Weather combine their experiences in weather instruments, storm studies, cloud formations, and weather fronts to prepare their forecasts and share them with other students via a blog. In a class I visited, the fourth-grade students used their weather station to prepare forecasts that they shared every day with the principal to help her make the decision about whether to have outdoor recess. And in a related news article, check out how fourth grade weather watchers are creating forecasts that are telecast on the Internet as well as on the school’s Web site.

Cruising the Climate with Spreadsheets shows how elementary science methods teachers found local weather data online, created Excel spreadsheets to organize the data, and interpreted the data from both local and international sites to learn about climates. This activity could be used as a purposeful workshop to brush up (or introduce) skills in spreadsheets. The author includes a list of online spreadsheet tutorials and tips for inserting or deleting symbols. I was not aware of this feature, so I learned something new, too. (Note: I use the Mac 2008 version where inserting symbols is part of the Object Palette under the View menu or in the Toolbox.)
NSTA’s Early Years blog has detailed ideas and resources on exploring the concept of evaporation with younger students, related to the article Where Did the Water Go?
If you’re looking for lesson ideas or sites for students on topics related to this theme, check out these K–4 SciLinks keywords:

At the 5–8 level, there are many keywords leading to websites on weather and climate. In SciLinks, use the basic keywords “weather” or “climate” to access them.
In this issue, all of the articles deal with the theme of weather. I’m going to continue reading and in the next post, I’ll share more resources on seasons, clouds, and instrumentation.
Check out the Connections for this issue. Even if the article does not quite fit with your lesson agenda, this resource has ideas for handouts, background information sheets, data sheets, rubrics, etc.
