Students discuss human behavior, sexual selection and the underlying genetic and evolutionary reasons for mate selection. The, in groups, they rate the attractiveness of certain individuals and measure facial features for symmetry.

Graph polynomials and identify the end behavior of each polynomial function. The class differentiates between linear, quadratic, and other polynomial equations.

Students explore how different materials (sand, gravel, lava rock) with different water contents on different slopes result in landslides of different severity. They measure the severity by how far the landslide debris extends into model...

Students compete in playground games in order to review velocity and wave behavior in real life situations. They demonstrate understanding by calculating velocity in their "Playground Games" packet.

Learners experiment to determine the difference between an acid and a base. They study the concept of adding a buffering agent to make an acid more basic. They study the pH scale.

What does size have to do with it? Learners analyze different mixtures, both homogeneous and heterogeneous, to discover the properties related to the size of their particles. The activity connects these properties to those of...

Doing is more effective than watching. Learners use spaghetti to discover the relationship between the unit circle and the graph of the sine and cosine functions. As they measure lengths on the unit circle and transfer them to a...

This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag...

Students investigate physical and behavioral characteristics of different microbes and create research- based 'Microbe Biographies.' students compare microbe sizes and examine how size of a microbe relates to its physical and behavioral...

Students concretely illustrate and define a macromolecule, observe the unique behavior of polymers and relate to their knowledge of molecules, and use the scientific process to determine the difference between Newtonian and non-Newtonian...

Students explore chemical cahnges and the effect of temperature on chemical mixturees, They make observations of the behavior and appearance of certain chemical mixtures and reactions.

Learners create instruments to capture different types of insects. In this The Greatest Show on Earth: The World's Smallest Animals lesson, students compare the attributes of certain insects and record the data on a chart. After catching...

Students examine the giant squid and its habitat. In this giant squid lesson, students discover the size, behavior, and natural habitat of the giant squid. Activities range from scientific information to myths and folklore. Students...

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....

Electromagnetic radiation behaves like both a wave and a particle. Help classes explore this concept through a lab investigation. Young scientists create optical interference patterns on a glass slide using a carbon layer. They analyze...

Ride the wave to an understanding of refraction! The first in a series of two inquiry-based lessons challenges learners to create transverse waves with two different types of springs. As their wave hits an object, they observe the change...

Students investigate millipedes. In this math and physics lesson plan, students examine the millipede's physical structure and characteristics by observing its behavior in given activities. Pupils will hypothesize whether they think the...

Students observe the behavior of termites and draw conclusions about their behavior. They record data as to termite behavior and recognize elements in the experimental design which must include a hypothesis.

Students are given a pond snail in a clear glass and asked to make observations on the snail's form and behavior. One of the key ideas is that seemly common subjects (like snails) often have surprising or interesting properties.

Sixth graders how primary research is carried out. They design a simple survey questionnaire to interview people about their week average television watching time. They analyze the results and write a report based on the information.

Time to study the most sensible function — rational functions! The seven-lesson unit develops the concept of a rational function through a connection to rational numbers and fractions. Scholars graph functions, solve equations, and...

An informative module highlights eight polynomial concepts. Learners work with polynomial functions, expressions, and equations through graphing, simplifying, and solving. 

Tenth graders distinguish between acids and bases. In this pH lesson, 10th graders view a PowerPoint and discuss the characteristics of an acid and a base. They investigate natural substances to determine the pH level of each.

Tiny particles can provide big learning opportunities! Middle school scientists explore the world of nanoparticles through reading, discussion, and experiment. Collaborative groups first apply nanotechnology to determine water...
