We – you and I, all of us – have all been called to be the salt of the earth. We don’t look the same, think the same or act the same. We have different interests, different passions, different histories and backstories that have made us who we are.Read More
What is your parenting style: Shepherd or Sheepherder? Jesus was the Good Shepherd. He marked the path and led the way! I believe He gave us a pattern. He gives us some clues about good or true shepherds in the scriptures.Read More
You made it to round three! I'm so happy! This one will be awesome. You'll see. Today's post is going to complete our Human Body series. I will continue by giving you even more hands on science experiments to do with your kids. So, put on your goggles and lab coat and let's get started.
This picture got a lot of likes on my facebook page and it was really the easiest experiment to do. You need two things: red or pink play dough and a bowl. First you get a small bowl. The larger the bowl the more brains you will have to make. Maybe you want to be ambitious and use a bowl that will fit your child's head, go you! Next, Cover the bowl with the play dough since some of it will show through. Then, roll the remainder play dough into snakes. It doesn't matter how long your snakes are. You will need a variety of sizes but they all should be about the same thickness. Start by bending the snakes into S shapes. Take a look at the pictures to get a general idea. There is no wrong way here. The hardest part is getting the snakes to stick well enough on the bowl. If you wanted to, you could try gluing them. It took days for mine to harden and then pieces would fall apart. I wasn't really expecting it to last too long so it was not a big deal to me. If you want to keep yours, maybe try modge podge glue over the whole thing when you finish. If you have a suggestion that worked for you and want to share with others, leave it in the comment section below.
Here is the link I used for the idea though I simplified it. The brain was originally listed as a Halloween decoration! Double uses here people!
Here is a link for DIY play dough but since cream of tartar costs just as much as buying ready made play dough, it may not save you money if you are only making one. I think one can of play dough per brain should be enough if the brain is not too big. Also, there are tons of different recipe ideas if you want to make things like Chocolate or cotton candy play dough.
Here is another activity we did for the brain.
I drew an outline of the brain myself and then sectioned it off. It may be easier to print it out. Use card stock if you want to use play dough. Otherwise you can just color it in. Here are some additional ideas that go along with learning about the brain.
Lets see, what else did I promise from last week... Oh yeah, lungs!
Here is the link I followed from Pinterest.
This lung experiment took more planning than I wanted but still it was easy enough. I took a video of it to show people on my phone when they ask about home schooling. Yeah, I'm bragging to them but now you can do the same thing! Aside from the .75 fake sprite I bought, (my kids were in Heaven or maybe just a sugar high) it was made with things I had around the house. Yes, I do keep balloons around my house. I actually have a kid that I babysit who looks forward to getting balloons at Sis. P's house. I'm like the cool aunt! Make sure you use non bendable straws. I didn't cut two holes in the lid of the bottle as the directions from the site said- too hard. Instead I put tape around the straws nice and snug. I used rubber bands to secure the balloons to the end of the straw. The directions also said to use a big balloon for the bottom of the bottle. You know, the kind with the rubber band attached that you bang back and fourth trying to annoy your brother with? I didn't have one on hand, though you can get them 3 for a dollar at the 99 cent store, so I used a plastic grocery store bag. Anyone else have a bag filled with other bags living under their kitchen sink? I put a rubber band around the bag to hold it tight as well. Then just blow into the straws and you have lungs! Perfect unexpected side effect: one balloon often would get bigger than the other. Did you know the left lung is smaller to make room for your heart? We always made sure the smaller one was on the left by turning the bottle upside down if we had to. Coincidentally I drew the left lung smaller on my human body chart by accident. Bonus!
The digestive system surely has more experiments to choose from. I wasn't too thrilled with the outcome of this one, though I do think it teaches the topic very well and lots of websites have this experiment listed when teaching this concept. Here is a link that shows something like what I did.
I got a gallon sized Ziploc bag and filled it half way with water. I think vinegar and a little green food coloring might have been better to show that our tummy is full of stinky (but totally helpful) acid and in my imagination that acid is green (resist the erg to google it). I used an empty paper towel roll as the esophagus and as you can see in the picture above J put it slightly in the bag without getting it wet. Then we fed it bread. Something more colorful like cheese may have been more visually stimulating.
After that J used her hands to act as the muscles in our stomachs to break the food down ready to enter the intestines. We learned about the intestines on a different day though it could go along with learning about the stomach since it all makes up the digestive system. This day, however, was focused on the stomach and what goes on there.
Since I'm not super enthusiastic about this one I'm giving you a bonus link that looks very nifty to try. Give THIS life size looking digestive maze of awesomeness a go.
You can always make a Tee Shirt. It seems a bit strange, but it's sure to be a great conversation piece at any home school function. It would also be great reinforcement if you challenged the kids to tell about the digestive path anytime someone asked about the shirt. I can't even look at this shirt without laughing. I'd love to see a picture of one of my readers wearing their original digestive system shirt! You would totally rock in my book.
I'm going to end my Human Body Series with the nervous system. This was SO simple and really neat, even for me. By now I hope you have partaken of the awesome sensation of going back and fourth between a hot tub and a swimming pool. It really stuns the nerves system. That is this experiment on a giant level. We want to make it portable and able to fit on your table top. You start with 3 bowls. In bowl 1: Ice water. Bowl 2: room temperature water. Bowl 3: hot water of the non flesh burning variety. Have the student place one hand in the ice water and the other in the hot water. Keep submerged for 1 minute (3 if they have been bad that day ;-). Then place both hands in the lukewarm water. The hand that was in the ice is now very warm while the hand that was in the hot is now chilled. Easy! By the way, if you are following along on your Human Body Chart from Part 1, we colored in skin for this experiment.
Ok, so I couldn't find the link where I got this idea but It's simple enough to follow the steps above I hope. And I'm also giving you THIS link for an optional idea to choose from.
The human body is amazing! I didn't cover every topic we learned in our semester at home, or that is listed on the human body chart I made, but I have faith that you can come up with some one your own. Also, there is no rule that says each topic must have an exciting hands on experiment. If you comment with your email address I have an overwhelming list of resources I can send to you on the human body. I really think that this semester could be done inexpensively. To conclude this topic for now, I'll leave you with some books I kept on hand. If you have suggestions- post them in the comments below.
Thanks for reading!
The roar of the outboard motor drowned out all sounds as we raced across the bright blue ocean. My husband, Patrick, and I had left our children with my parents the day before. Together, he and I had flown to a tiny Tongan island in the middle of the Pacific Ocean. Upon our arrival, we learned of a snorkel trip planned for the next day. Following my life’s motto that “it is cheaper to do it now than to come back again later,” we had signed up immediately. I felt nervous about swimming in unknown waters, yet thrilled to try snorkeling for the 2nd time in my life. As the sun warmed us perfectly, we zipped along towards our destination.
Arriving at the preplanned anchor spot, our guide inspired me to regard him as a teacher instead of a beach bum. Initially, he surprised me with a bit of useful information. It was significantly more academic than I had expected from a sunburned Aussie on a barely-inhabited island. So, I asked a question I had been pondering: “What kind of rocks are on the beaches here?” I had begun wondering about the rocks on our first day at the beach. They were porous and very sharp. They appeared dark and yet not at all volcanic. This surprised me because prior to the trip I had read that the Tongan Islands were atolls. I could not make sense of it in my mind, and I was the only person in my family who seemed bothered by the discrepancy. When our guide quickly and easily identified the rocks as coral limestone- essentially petrified coral- I felt euphoric and knew I could learn volumes from this unlikely mentor.
The remainder of my experience changed from a sight-seeing trip to a nature study excursion. Once I determined that our snorkel guide could help me study nature, rather than simply observe it, my approach changed. Rather than simply looking for interesting or colorful fish, I was looking for questions. I tried to find things I did not understand to ask him about. He would answer each question and explain what else I would observe nearby. I would jack-knife dive down to the coral reef searching for what he had described. One by one, the other participants boarded the boat and waited for me to finish. I swam alone until I felt it would be impolite to keep everyone waiting any longer, and then I climbed aboard. The others had blank stares in their eyes- they really appeared bored. I felt breathless and enlivened. I wished I could stay longer. I wanted to study every inch of that coral reef.
Our morning in the ocean was not my first, nor certainly my last, nature study journey. I had grown up spending time hiking and camping with my dad. Some of my earliest happy memories had taken place in the Wasatch mountains. I had always enjoyed being out in nature, but I had been a fairly passive participant. I enjoyed the outdoor activities, but I did not give much specific thought to the creations around me. A change in me occurred when I began studying nature with my children. Their incessant questions taught me to be more curious. Children wonder so many things; nature study comes rather instinctively to them. Thankfully, we homeschool moms get to enjoy the journey with them.
Nature study adventures have been an integral part of our homeschool from the very beginning. When my oldest was in preschool and we were choosing a curriculum, I learned that early literacy will improve more and easier if children are given something to be literate about, rather than simply taught literacy skills. Nature was an obvious place to start because it is such a tangible topic to introduce to children. It is fascinating, encompassing, and abundant. Children can learn about it by observation, experience, and reasoning, not just by regurgitation. We have found available nature to study wherever we have lived - even in a city center apartment. We have also found many friends whose willingness to join us in our excursions has increased safety, accountability, and fun. Most importantly, we have strengthened our relationships and come to regard our time exploring together as a little piece of paradise. Although the annual amount of time we can devote to nature study varies with life’s changes, we make sure to include it on the schedule of each semester’s school plans.
Including nature study in your homeschool is simple, but not necessarily easy. Most of us feel more comfortable with a curriculum to follow and a rubric to assess our efforts. Nature study does not lend itself to those structures very well. Instead, we must look around ourselves, find the resources that we have, schedule a time to go exploring, and then follow through regardless of the weather. In addition, we have to accept the fact that sometimes there are no perceptible “outcomes” until much later. The challenge, then, is to find a way to keep it simple while providing enough structure for your family’s learning life style.
At the LDSHE convention this May, I will explain how to make nature study simple and achievable in my class entitled “Exploring Together: Every Family Can Do Nature Study.” The class will not be based on any particular philosophical approach. Instead, I will provide some practical, down-to-earth advice about why and how to accomplish nature study, and how to improve it if you are already doing it. Although I am not an expert, nor a scientist, I am excited to share my passion about nature. I hope that at the end of my class, you will feel encouraged that your family can explore nature together no matter where you live so that you, too, can experience a little piece of paradise.
- Louisa Wells loves experiencing nature. Some of her earliest memories are of hikes and camping trips with her dad. She is a mother of five children, and she has been sharing nature with them their entire lives. Although her children definitely learn from their adventures, Louisa feels that she is really the one who is learning the most.
