Learners become butterflies to complete an activity that has them collect tokens that represent food, water, and shelter. They must collect their necessities while in competition with other butterflies in the same area. Once the...

Do some experimentation with reduction-oxidation! Stoichiometry superstars use a single-replacement reaction to study limiting reactant, theoretical yield, and the reactivity of metals through a lab activity. The teacher's guide includes...

All sodium carbonate may not have the same amount of carbonate, but it should have the same percent. Learners write and balance an equation to predict the chemical reaction between sodium carbonate and zinc acetate. Through the lab...

Elementary ecologists pretend to be migratory hummingbirds. They fly between wintering and nesting grounds, trying to reach a habitat haven. In a musical-chair fashion, some birds will miss out, and are removed from the game. To further...

Observing plant succession doesn't have to be a decade long process. A hands-on lesson plan has groups study succession over a designated space. Learners use their observation skills to record differences in plant and soil...

Learners explore how the Constitution provides for separation of power and limited government, as evidenced by the three branches of government. They participate in role-playing situations, group discussions, and complete worksheets to...

Going up and down makes a more exciting ride. Pupils recall what they know about continuity and limits of functions. Working in groups, classmates design a skateboard ramp that meets a given set of criteria, using at least three...

Why would someone need contact lenses that offer UV protection? With a 28-page packet full of instruction and worksheets, learners discuss solar radiation and its potential harm to eyes. They make snow goggles similar...

Life has its ups and downs ... especially if you're an animal! Biology scholars engage in a population study through an inquiry-based lesson plan. Pupils work together to explore the factors that affect deer populations, then examine the...

As a stand-alone or as part of the intended unit, this is a valid investigation of what causes condensation to occur.  By limiting the amount of air around a cold cup of water and comparing it to one out in the open, they find that...

Complete teacher narrative and presentation slides for teaching about Earth's water make up the bulk of this lesson. Embedded within the slide show, you will find videos about the water cycle, keeping track of the limited supply of fresh...

The sky is the limit when printing custom 3-D shape templates from this site. Not only can you pick your shape and pattern, there is an option to upload an image for the different sides of the geometric shape. Let your learners have fun...

Can't read this now, I'll have to check it out later. A teacher's time is always limited. So often as we peruse the web for personal and professional content, we come across sites and information that we cannot immediately...

Have you ever tried to find hidden items in a picture when you don't know what you are looking for or how many things are hidden? A lesson applies that same concept to sampling the deep sea habitats. Participants must first create a...

Our bodies have some amazing capabilities, but there are some limitations. Explore the limitations of the human eye through the eighth lab activity in a series of 12 biology lessons. Individuals measure their own peripheral vision...

Did you know light can decrease visibility? Light pollution absolutely makes it more difficult to see stars. Scholars build a simple magnitude reader to determine the magnitude of stars. They use these data to estimate the impact of...

Japan is one of only a handful of countries that constructs buildings that are almost earthquake proof. The 13th lesson in the 20-part series challenges scholars to build structures to test against earthquakes. With limited materials and...

The Arctic food web may be more limited than other environments, but it has all the same components. With an interactive activity, pupils assume the roles of the components of an Arctic food chain. They move around and link themselves to...

Earth or environmental science pupils are assigned to be carbon sources or sinks. They ask yes-or-no questions to try to figure out which one they are. Then they discuss ways people can have positive effects on the changing climate by...

Should Congress limit how much a corporation spends to support a political candidate? Here is a fantastic lesson plan and activities to help young citizens approach this question.
