Students investigate the properties of oxides and observe their periodic trends. In this behavior of oxides lesson plan, students experiment with metallic oxides and non-metallic oxides to determine if they are acid, basic or amphoteric...

To prepare for the activity, STEM classes read about nanotechnology and the amazing properties of graphene. They collect a graphene sample from pencils, and then connect them into simple circuits to determine whether it makes a better...

Here is the first of four experiments to differentiate among unknown liquids by their behaviors and properties. Pupils observe how different liquids respond to being placed on plastic and paper, and they take notes about their...

Couches, carpets, and even computer keyboards now advertise they are spill-resistant, but what does that mean? Scholars use physical and chemical methods to coat surfaces with thin films to test their hydrophobic properties. Then they...

Engage in an 8-day study of different modes of transportation. Your students explore the concept of location and define the physical characteristics of places, such as, land forms, bodies of water, natural resources, and weather.

Examine the evolution of various species of hominids from their earliest existence approximately 4.5 million years ago to today. In small groups, learners research one of the ten stages of hominid evolution and then create a poster and...

Differentiate between temperature and thermal energy. Your class will build a thermometer using simple materials and develop their own scale for measuring temperature. Discuss with your class and consider why engineers need to understand...

This lab activity is geared toward experienced chemistry learners, in particular, those who are familiar with organic chemistry. They will create a synthetic elastomer  and then make observations and measurements of its different...

Students investigate the properties of plastic eggs filled with solids, liquids, and gases and use these observations to hypothesize whether a chicken egg is hard-boiled or raw.

High schoolers investigate the characteristics of alkaline earth metals. In this alkaline earth metals lesson plan, students experiment with a variety of alkaline earth metal compounds and perform tests to observe their properties. High...

Earth science learners experiment with the water-holding properties of sand, pebbles, and clay. They apply their findings to the building of a well. This activity is engaging and tactile, and it demonstrates the importance of considering...

Looking at numerous examples of triangles, each with different properties, geometers develop their understanding of congruency. They use the notation of a counter-example to disprove certain conjectures and prove geometric theorems and...

Having a good working knowledge of math vocabulary is especially important for geometry learners. Here are 119 pages worth of wonderfully constructed definitions, constructions, formulas, properties, theorems, and postulates. This is a...

Enjoy this nicely organized worksheet that puts together multiple problems regarding trapezoid proofs. The resource can be used as a guide that begins with proving properties and ends with solving for measures of line segments.

Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

Sixth graders explore the concept of order of operations. In this order of operations instructional activity, 6th graders view a powerpoint about order of operations in society. Students post on a blog about order of operations.
