Humans are quickly depleting Earth's fossil fuels and locating them is becoming increasingly difficult! Layered muffins are used for models as young geologists take core samples in order to determine the presence of oil. Consider first...

Life on Earth is made possible by the unique composition of its atmosphere. Working collaboratively, a scale model is created as young scientists learn about the different layers of gas that surround the planet. Cards are included that...

Break hearts with this lesson plan: chicken or sheep hearts, that is! Your class examines the external and internal structure of the heart with a dissection activity. A handy anatomy resource provides the necessary materials for...

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...

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

Your class will agree that this is the best way to demonstrate the greenhouse effect: making solar s'mores! Using a clear plastic cups as mini atmospheres, lab groups compare how adding different materials affects the melting rate of...

Model how the sun's energy strikes the planet and help your class relate it to a climate map. Assign small groups an individual climate zone to discuss. They reflect on and research how humans survive in the assigned climate and write a...

In cooperative groups, middle schoolers contemplate the probability of 18 different situations occurring. After they make predictions, they compare them to the actual risk factors. This eye-opening exercise demonstrates that the odds of...

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...

Ever wonder what the villi in the small intestine do? I bet your class would love to find out. Mesh netting is used to represent small blood vessels on the outside of the intestine, and a chenille bath mat is used to represent the villi...

Glucose is a simple sugar and a molecule that can be illustrated through modeling. Scientific investigators with visual impairments use hands-on models to reconstruct the process of bonding molecules. The tools used in this activity are...

This complete set of instructions for creating your very own butterfly garden and habitat is so cool! With some seeds and the handy resources in this activity, you and your class will be able to determine which type of habitat is best...

While cities had only a small fraction of the population in colonial America, they played a significant role in pre-revolutionary years, and this was certainly true for the largest city in the North American colonies: Philadelphia. Your...

Challenge your class to construct a definition for trapezoids. Looking at four examples and four non-examples, young scholars individually create definitions and use them to classify an unknown shape. Allow for small group and...

Visual models are excellent teaching tools when explaining equivalent fractions. Looking at a rectangle cut into twelfths, learners first identify the shaded fraction, and then explain whether the fraction is equal to one-fourth....

Increase the depth of your class's fractional number sense with this number-ordering activity. Given four fractions, each with different numerators and denominators, young learners are asked to place them in order from smallest to...
