Break hearts with this lesson; chicken or sheep hearts, that is! Your class examines the external and internal structure of the heart with a dissection activity. Extremely detailed notes are provided for you to safely guide learners through the exploration. It is highly recommended that you access and teach the previous two lessons that are part of the same unit on the heart and circulation so that pupils are already familiar with the structures they will be looking at. If you cannot purchase class sets of hearts, you could opt to dissect one as a demonstration.
Lub-dub, lub-dub. Why does the heart beat? Why does blood circulate throughout the body? Life scientists find out how important circulation is for dissolving and dispersing materials by timing how long it takes for food coloring spread through a dish of water unaided. Though this lesson easily stands alone and can be used in your human body systems curriculum, make sure to consider the rest of the unit by this publisher.
Don't be chicken to try a lesson plan that compares the anatomy of birds to humans. Read the background information so you don't have to wing it when it comes to the anatomy of a chicken. Prepare cooked chicken bones by soaking them in a bleach solution, then guide your young scientists through an exploration of bones and cartilage. Finish the activity with a comparison between chicken and human anatomy to identify the similarities and differences. Note: be sure to allow yourself enough time to prepare the bones at least a day in advance.
There can be a steep learning curve when teaching about exponential growth, but the lesson plan helps kids make sense out of the concept. When talking about exponential growth of viruses, learners may not be very interested, but when you are talking about money, engagement levels shoot up exponentially! Once the concept is understood, applying it to viral replication or anything else should be straightforward. 
What better way to study the structures of organisms than by creating a new being? After considering different types of skeletal supports (exoskeleton and endoskeleton), budding biogeneticists work together to create their own animals - first on paper, then using basic materials. They must decide whether an external or internal skeleton would work best, then think about how the creature will move. Depending on the background knowledge your class has, you may want to allow for some research time to look into different skeletal structures of a variety of animals to help them brainstorm. The actual time needed for the activity will vary depending on the age of the learners.
How many Calories one needs on a daily basis is dependent on a number of factors including gender, height, and activity level. In the third of seven lessons about energy and food, young nutritionists calculate the number of Calories necessary for different sizes and typical exertion levels. In addition to the science involved, there are some great math skills practiced here, too, from converting between metric and standard, to addition, subtraction, and multiplication.
Between the pull of gravity and the push of air pressure, it's a wonder animals can balance or move at all. With a hands-on lesson about the center of gravity, learners discuss their own experiences with the topic, then work with partners to experiment with the concept through making balances, as well as trying to balance themselves in different circumstances. 
Circulate this news: the heart is a pump containing one-way valves! Following the previous lesson on the external structure of the heart, learners now take a look at the inside. They use a three-color diagram to label a black-and-white photograph of a human heart cross section. If working through the entire unit, they also take time to add to their concept maps. When you want to get deep into the heart with your middle schoolers, this lesson will take you there!
In groups of six, anatomy and physiology fans imitate how blood flows from place to place in the circulatory system. They will discover that different sizes of vessels transport various volumes of blood. The activity requires the class to actually construct and calibrate their own measurement cups, which requires more time that the demonstration itself; but as long as you follow up with an in-depth discussion, it would be worthwhile. The lesson plan is part of a larger unit by a trustworthy source, but it can stand alone as well.
Aspiring anatomists label a photograph of a human heart by comparing it to a colored diagram on the same page. The video that is mentioned in the procedure does not seem to be available, but the overview provides plentiful background information, a detailed set of instructions, and a crisp worksheet focused on the external view of the heart. Classroom slides that you can project for a larger view of the image are available at the publisher's website. Use the lesson alone or in conjunction with the next lesson in the larger unit, which takes a look at the interior of the heart.
Biomanufacturing and genetic engineering are very common practices around the world, but what exactly does it entail? Young geneticists find out through a series of labs, a discussion, and an in-class presentation to report their findings. There are lab procedures and a PowerPoint presentation included in the materials; although the PowerPoint is called Biotechnology in North Carolina Today, it is very general and could be used in any state. The materials included with the instructional activity are very text-heavy, so they may need some modification for English learners or students with special needs. 
Meant to be given both before and after a unit on the circulatory system, this assessment is a set of 15 multiple-choice questions. Middle schoolers are queried on what they know about the structure and function of the heart and blood vessels. It also touches on how the heart handles microgravity and how animals without circulatory systems transport materials. The pre-assessment session also involves starting a concept map that is to be added to throughout the following lessons.
Being an astronaut takes not only high mental acuity, but also a high level of physical fitness, especially for those who spend a long amount of time away from Earth, such as the astronauts serving on the International Space Station. Without the constant pull of Earth's gravity on the body, space travelers quickly lose bone density and muscle mass. See how well your middle schoolers or high schoolers understand the concept through a drawing and writing activity. Learners draw and label the bones and muscles of an arm that has been in space versus one that has been on Earth, then devise a diet and exercise plan to combat the bone and muscle atrophy of microgravity. 
Mini microbiologists play a card game in which they group microorganisms by groups: virus, fungus, protist, or bacteria. Then they identify the roles different microbes play in the natural world and explore how humans effectively use certain microorganisms in food production and industry. This lesson is part of a unit on microbes, and is a fun addition to any middle school microbiology curriculum.
In the preceding activity from the unit, beginning biologists discovered that microorganisms are everywhere, so the question follows, why are we not sick all of the time? Class members read and discuss an article in small groups about immunity. They do a little additional research online and use gathered information to complete an included crossword puzzle. The activity can be used as part of the unit, or alone in a health curriculum as well.
Teach your exercise enthusiasts to read their pulse rate at the radial artery for 15 seconds and multiply by four to calculate beats per minute. Have them perform a variety of activities, recording their heart rates after one minute of each. Though this is a classic activity to conduct when studying the heart, this particular resource provides extensive background information and a detailed lab sheet that will keep your heart rate in check as you prepare! If you are interested, how the blood is affected by space travel can also be discussed with your class.
Find out how we describe the force created by the blood against the walls of the vessels in a heart-pumping lesson! As part of a unit on the heart and circulatory system, cardiology kids use a blood pressure monitor to find their systolic and diastolic pressures. To conclude the lesson, they discuss how blood pressure relates to health and graph class member's readings. As well-written as this lesson plan is, pressure to prepare will be removed from your heart! 
It takes some work to ensure you have a balanced diet, but once you know the types of foods that are good for you, it becomes second nature. In the sixth of seven lessons about energy and nutrition, learners create a healthy eating plan using resources from the USDA. Note: The activity was created before the USDA switched from MyPyramid to MyPlate, so you will need to update some of the resources in the activity to ensure it is up to date.
When it comes to eating a balanced diet, portion control is paramount, but what is the difference between the serving size on the nutrition facts label and a portion as determined by the USDA? In a comprehensive look at portion control, kids will estimate and measure out serving sizes of four different foods, then measure out the stated serving size. To see the activity in action, watch the video included in the Additional Materials section. 
Got milk? Or almonds, sardines, or tofu? Calcium is important throughout life, but especially so for developing bodies. If teens do not consume enough calcium while they are growing, they are at a much higher risk of osteoporosis and other health issues. Beginning by looking at their own eating habits, learners try to place the foods they've consumed over the past 24 hours on the Healthy Eating Plate. Next, they examine both dairy and non-dairy foods that are high in calcium and how many daily servings they would need to meet the recommended daily allowance for teens.
