Yah, I know some of us are winding down from schooling for the summer months, but I can’t help but stay on the lookout for resources I know I’m going to be needing again all too soon. I’ve come across some interesting science things of late that I want to check out – perhaps you, too, can find something useful. For your perusal:

Classic Science Life: free life science e-textbook to download; either download by chapter (there are 36) or by unit (9 units); online courses also offered 

MS Nucleus: free science curriculum, K – 6 and some secondary 

Science Interactives and Videos  

Annenberg Learner animations on a number of topics, including volcanos, DNA, the rock cycle and others; also has interactive on subjects other then science 

wickED: animations about the earth, including plate tectonics, the rock cycle

Njoy Science: Hands-On Learning for Homeschoolers

Tags: homeschool science apologia science science curriculum homeschool science for homeschool

It’s 11:15 on a Thursday morning at Lakeside Presbyterian Church, in Mooresville, NC, where a Physical Science class has just finished up, and preparations are being made for the next class in Biology. On a long table at the back of the room, bottles of rubbing alcohol, hand sanitizer, and water have been neatly placed alongside large, clear plastic tubs, and paper towels. It’s the clean-up area for today’s lab which will involve dissections of frogs and perch.

As the kids arrive, one girl is clearly excited about the task she will undertake, that of snipping, peeling away, and poking through frog innards. It’s just the sort of anticipation the instructors of nJoy Science hope to build through their hands-on science labs. Led by homeschooling parents, Richard and Gail Hawkins, nJoy science programs teach the scientific method while acknowledging and honoring God and His Creation. (Read more about the Hawkins’ background and the history of nJoy here).

The Hawkins, (who both hold science degrees), have developed their own general science curricula for ages 6 to 11. For middle- and high-school aged students, they offer Apologia science courses. The courses are year-long, and meet every two weeks.

Today, Gail starts out her class with a quote from former outstanding  Biology Teacher Award recipient, Susan Offner. “The learning that occurs in a dissection is qualitatively different from the learning that occurs in a lecture or paper-and-pencil setting.” Gail agrees with this sentiment, as she finishes the quote, “No model, no video, no diagram and no movie clip can duplicate the fascination, the sense of discovery, wonder and even awe that students feel when they find real structures in their own specimens.”

The statement is about to be tested as metal trays containing frog specimens are placed before groups of two and three students at each table. The projector is started up, the gloves are snapped on, and Gail begins with some basic frog anatomy, and continues with step-by-step diagrams and instructions for performing the dissections.

The kids learn that a frog has two sets of eyelids, (good for the amphibious existence it experienced when alive), and after some careful snips with scissors to the sides of its mouth, they discover that the frog’s tongue is attached at the front (not the back, like ours), which is why its tongue could be whipped out so quickly to catch bugs. Using scalpels, the kids continue to cut down through skin and muscle (there are some, “ewws,” and “yucks,” mostly from the girls), to reveal the creatures’ organs. One of the reasons frogs are good to dissect, Gail explains, is that their insides are similar to ours and easy to identify. She directs them to find the heart, liver, intestines, lungs, gall bladder, kidney, and reproductive organs. They also dissect the stomach to determine the contents of each frog’s last supper (usually consisting of beetle and grasshopper parts).

After the thorough examinations, the students sketch and label what they see. When they’re finished, they scrape out the remains, and wash the trays to prepare for the next dissection of a perch.

When the lab class is finally over, Gail announces that these were the last dissections for the year, and a general “Awwww,” comes back from the group. They sound genuinely disappointed. Does this mean today’s activities have succeeded in stimulating that sense of awe Gail spoke of at the start of the class? The kids will have a chance to answer that question. They’ve been asked to mull over and write down for next time whether or not they agree with the Susan Offner quote, and if they have more or less respect for God’s creation as a result of the dissections.

One student mentions a sense of accomplishment she feels from “single-handedly” dissecting the frog. “It’ll definitely help me remember the anatomy better,” she says, further quipping, “I guess the trauma has burned it into my brain.”

She may not be so appreciative of what she’s learned today when those vivid images come back into her mind  -- right about suppertime.


Do you have a local homeschooling class or co-op that you feel provides a great learning experience for your children? We’d love to hear about it. Please leave a comment or post.

Worm Dissection: A Study In Psychology?
Category: Science

Every kid that takes biology is going to have to at some point participate in the dreaded dissection lab. Today was my turn. The tools are placed out on the table, the tray is put in front of you, and the dead thing you’re going to be dissecting is plunked down in the middle of the tray. You get ready to learn a thing or two about…psychology?

The girl who I was partnered with started to look a little sick as soon as the worm was put on the table. I immediately moved away. If she was going to throw up, she could do it on someone else. We began cutting open the worm with the scalpel when to my surprise, the girl started laughing. Once everything was pinned down properly, she was still laughing. Even when we were poking around in there looking at the organs and things with the tweezers, the laughter did not stop. And when the worm started oozing something the laughter became hysterical. I guess that was her way of dealing with the grossness of it all. Maybe she was crying on the inside.

The girl sitting in front of us responded in the complete opposite way. As soon as it was announced we’d be dissecting today she yelled, “YES! This is what I take biology for!” And the rest of the class just kind of stared at her. Every time she would make an incision in the worm with the scalpel or take out a piece of something with the tweezers she would smile, or nod, or make an appreciative sound. Her favorite part was when we started analyzing its guts.  When we were finished, she asked if she could take the worm home with her. It took me a second to realize she was joking.

Then the guys, of course, had to act all silly and crack jokes about everything the whole time, pretending they didn’t care at all that some worm juice just squirted into their face, or that they had to cut open right next to the main blood vessel. Some of them refused to wear gloves just to prove their manhood I guess, and others made fun of the people that were acting squeamish. Really though, none of the guys enjoyed it either. They just had to put it on or they’d look like a bunch of wimps.

I, on the other hand, didn’t react to it like any of these people. I cut open the worm, looked around at its insides, drew my diagram, and literally washed my hands of the whole affair while the one girl continued laughing, the other continued loudly appreciating the worm’s digestive system, and the guys continued to act silly instead of just getting it done.

What I really got from today’s dissection was a look into the complex minds of people and a realization that you never know how you’re going to react to something until it happens. I wonder what’s going to happen next week when we cut open some crayfish…
