Using a simple circuit with the battery representing the brain, future physiologists test to see which solutions conduct electrical "nerve impulses." Enlighten learners with plentiful information on electric signals in the nervous system...

Each genetic disorder has its own story to tell. A research-based lesson asks individuals to investigate a genetic disorder using scientific web resources. Guiding questions ask them to explain the mode of inheritance and the effects of...

With a partner, youngsters measure their pulse and breathing rates, both at rest and after running in place for a minute. While this activity is not novel, the lesson plan includes a large-scale classroom graphing activity and other...

Turn your classroom into a greenhouse with a lesson on plant growth. First, investigate the different parts of seeds, identifying the seed coat, cotyledon, and embryo. Then plant the seeds and watch them grow! Measure the new plants...

In order to learn that mold spores can be found in the air, observers grow bread mold and make observations for a few days. Afterward, they participate in a class discussion to arrive at the knowledge that bread spores are present in the...

Explore various ecosystems from around the world as your class discovers the interdependence of all living things. Using the provided sets of ecosystem cards, young scientists work in small groups building food webs to demonstrate the...

Small groups place sand and ice in a covered box, place the box in the sunlight, then observe as evaporation, condensation, and precipitation occur. These models serve as miniature water cycles and demonstrations of the three phases of...

Get close up and personal with a drop of water to discover how the polarity of its molecules affect its behavior. Elementary hydrologists split and combine water droplets, and also compare them to drops of oil. Much neater than placing a...

One of water's claims to fame is as the universal solvent. Young physical scientists experiment to discover which materials dissolve in this special compound. You could never be more prepared for teaching this lesson than by using this...

Ecology candidates culture pond water organisms over a few days time, then they experiment to find out how increasing nutrients affects the population. As part of a unit on water, this exploration gives your class an understanding of how...

Water may appear to be crystal clear, but there could be dissolved substances present. Lab groups make a one-part-per-million of a food coloring solution to demonstrate this concept. As part of an outstanding unit about water, this...

Using paper chromatography, water watchers discover that several substances might be dissolved even though they aren't visible. In this case, you will prepare a mixture of three different food colorings for them to experiment with. A...

Clever! In order to compare indoor and outdoor dispersal rates for the movement of gases and particles through air, collaborators will participate in a classroom experiment. Set up a circular grid and set students on lines that are...

In class, your emerging environmentalists construct dust catchers. They take them home for a week or two, and then bring them back into class to examine under a magnifier. From this activity, they learn what makes up dust and that...

In lab groups, young scientists place aluminum cans with a bubble-solution cap into different temperatures of water to see what size of bubble dome forms. As part of an atmosphere unit in preparation for learning about convection...

Let's heat things up! This simple experiment demonstrates for students the important role the sun plays in providing the earth with energy. Place one cup of water in direct sunlight and one in shade, then take measurements in order to...

Uncover the science behind the beautiful phenomena of rainbows with a simple demonstration. Shine light through different-sized containers of water as young scientists learn that rainbows occur when visible light is split up into its...

During a three-part lesson, learners make a cabbage juice pH indicator and use it to analyze the waste products of yeast after feeding them with sugar. The intent is to demonstrate how living organisms produce carbon dioxide, which is...

Several subjects are addressed within the context of a science lesson about the sun's ultraviolet rays. Elementary earth scientists consider protection of the skin with sunscreens (health), estimating and measuring surface area or an...

Don't lift another finger, this physical and environmental science unit has everything you need to begin teaching your class about energy. Starting with a look at the greenhouse effect, these lessons and activities take young scientists...

Compare the volume of an orange to the volume of liquid that can be extracted out of it. Also compare the mass of an apple before and after it has been dried out. In both of these activities, children find that there is an appreciable...

Physical or life science learners measure the amounts of water eliminated by intestines and the urinary system, and the amounts lost via respiration and perspiration. In doing so, they discover that the body's water must be replenished...

Send youngsters home to survey how they use water in their homes. Then bring them together to discuss which uses are essential for our health and which are not. A helpful video offers teaching tips for this lesson, and a presentation...

It's time to roll up those sleeves and get a little dirty in the second lesson of this series on the science of food. Investigate where plants and animals get the minerals they need to live in this two-part exploration of soil. First,...
