Humans eat around 93,205 miles of DNA in an average meal. Scholars learn how to extract DNA from a strawberry using a presentation. It walks through each step and explains why the process works. Comprehension questions encourage...

Digestion is an amazing and complicated process that provides humans with the energy they need to survive. Lesson six in this series on the science of food uses sliced turkey and a meat tenderizer to demonstrate how enzymes help break...

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...

Grandma said to gargle with salt water for a sore throat. Was she right? In the last part of the seven-part unit, lab groups design an experiment to test a cells reaction to salt solutions. The pupils conduct their experiment to answer...

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,...

Jiminy cricket! If you find yourself plagued by fear of dissection, these locust respiratory system dissection directions will walk you through everything you need to know. Teens inspect a living locust to begin with, then jump over to...

De-icing materials may have a harmful effect on our environment; have your class perform an experiment to test the nature of these effects. Scholars monitor the survival rate of a sample of daphnia as the concentration of a de-icing...

Learners investigate why theoretical probability doesn't always match reality. The activity involves using Python 2.7 (or Sage) to set up a Bernoulli Trial. It also involves setting up a spreadsheet to simulate the Birthday Paradox....

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...

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...

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...

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...

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...

Totally gross out your class with the eighth lesson in this series on food science. Explore the microscopic world of bacteria by taking swabs of different classroom objects and growing colonies in petri dishes. An engaging activity that...

Stability is key when building a bridge. Scholars explore the forces acting upon bridges through an analysis of Newton's Laws and Hooke's Law. The activity asks individuals to apply their learning by building a bridge of their own.

Mix it up and engage learners in a lesson on music and physical science. Using cups, strings, guitars, and voice, the class will experiment with sound vibration and frequency. They'll use each instrument and fill out a worksheet that...

If tap water is more acidic than ocean water, why are we so concerned about ocean acidification? The third installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program focuses on carbon dioxide levels in...

The size of a nanoparticle is difficult for pupils to grasp. A hands-on experiment is designed to give your classes perspective. Learners analyze different sports drinks for the content of electrolytes as an introduction to nanoscale....

Bridge the gaps in your knowledge of bridges. Individuals learn about bridge types by building models. The activity introduces beam bridges, arch bridges, truss bridges, and suspension bridges.
