We have begun our unit on living systems in science (thank GOSH because Earth and Physical science have quite literally killed me this year...seriously, I feel like the most incompetent teacher when I teach science...but I digress...). Our main focus for the past week before Spring Break was the circulatory and respiratory systems. I thought I would share some of the things we have been doing, in case some of you are in the same unit yourselves. To get us started, we watched a few BrainPOP videos about circulation and blood. I found these in the HEALTH section, not the science section. The kids were very enthralled with these videos (they ALWAYS are really) There was quite a lot of information in them, which got us started on the right foot. The videos mentioned how the circulatory system was the delivery system of the body and that all systems were connected to this one. After some discussion, the students created this Circulation Data Disk from the Easy Make & Learn Projects: Human Body (Grades 2-4) (affiliate link) book. The idea of this circular disk was to show how all of the organs in the body played a very special part in relation to the circulatory system. I purposefully whited out the info on the disk so that the kids could do the research themselves. Using our health and science books, the students discovered the role of each organ in circulatory system. We then used the Easy Make & Learn Projects: Human Body (Grades 2-4) (affiliate link) book and created a model of the heart. The kids diagrammed the model to up the rigor a bit. They then placed these in their science journals. Another great find (that the kids had a blast playing) was the Circulation Game from Ellen McHenry's homeschooling website. This is a free download and I am so glad I found it! It took a while to set up and explain, but once they were going, the kids really were into the game. They learned quite a bit about how blood travels through the body and how it disposes of waste. (just a little note, I printed out 5 of these and had each table play. That way, there weren't as many people playing on one game board) Finally, the kids watched the School House Rock video, "Do the Circulation". (I have the actual DVD Schoolhouse Rock! (Special 30th Anniversary Edition), (affiliate link) but you can get it on YouTube if the school doesn't block it....like mine does) I gave them the words and, combining language arts with science, we looked for all of the facts and opinions (as well as figurative language) in the song. We discussed why the writers would put opinions and figurative language in a song intended to teach us about the Circulatory system. The students decided that it was because without the opinions and figurative language, the song would be B.O.R.I.N.G! We also began working on our Body Systems project on Google Drive. I made a template for each body system and the kids all began filling in the information about the circulatory system. This worked out perfect here because the kids had so much background knowledge at this point. They didn't really need to do as much research since we were learning so much as it was! (click here to get the project for your own class!) This is a screenshot of the slide before the kids actually did any work. I forgot to take pictures of them working! To explore the respiratory system (a bit further, as we really were talking about it all along with the circulatory system), we first diagrammed the organs involved. Then, the students did a little experiment to measure their vital lung capacity (how much air can be forcibly taken in and blown out) and the tidal lung capacity (how much is taken in and out during normal breathing). The kids has SO much fun with this one! They really were surprised at how much air they *couldn't* blow. I think they all thought they would pop the balloons in one breath when, in actuality, they hardly inflated them at all! You can find the exact experiment and printables here. So there you have it. Our basic introduction to the systems of the human body. Up next is the digestive system. Wish me luck ;) What experiments have you conducted in your class to teach your students about the circulatory and respiratory systems? Follow me on Snapchat for even more teaching ideas!

This life-sized heart is part of a series of patterns I'm gradually releasing that make up all the organs of the human body. Difficulty: Medium You will need: A 2.5mm crochet hook anchor essentials creativa 4ply cotton in signal red, light orange, lemon, and dark blue #10 cotton or embroidery thread in blue and red Polyester toy stuffing A darning needle An embroidery needle A pair of scissors Note: 'Fasten off neatly' refers to a special way of fastening off which is neater and makes it easier to see where you should be crocheting on the next round (also known as invisible fastening off). This involves pulling up your yarn through your stitch, threading the yarn underneath the second stitch from where you pulled your yarn up, then threading your yarn back through the top of this stitch and down through the back of the work. There is a very helpful site that explains it clearly found here. Just make sure when you do this that you thread your needle through the SECOND stitch after the last stitch you made, otherwise you will end up with an extra stitch which may mean that all of the following rounds are out of line with each other. The false stitch that you create is referred to in this pattern as the 'new' st.

That's all from this pattern - I hope you have enjoyed it! If you have you might be interested in checking out some of my other organ patterns. If you have any questions please feel free to get in contact - the best way is to email [email protected], but you can also leave a comment below or on my Ravelry or Instagram pages. As always you're very welcome to sell finished products but I do ask that you don't re-post this pattern or claim it as your own. Thank you! Also here's some photos of the heart integrated with a set of life-sized lungs (pattern will be released at some point in future), and in the chest cavity of the life-sized skeleton I've made (patterns for various parts of this skeleton are being gradually released)

This Awesome Anatomy coloring page focuses on the heart and all the different parts of it.

There are three basic parts to an EKG: P wave: this is the wave that shows what is going on in the atria of the heart aka atrial contraction QRS: think ventricles, if there’s an abnormal QRS …

This lesson will make your students realize that even though they take their heart for granted, the heart is working hard to pump blood to different parts of the body to keep them healthy and running!
