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...

You are what you eat, or so they say! After surveying family and friends on a week of eating habits, learners analyze the data for patterns. They compare different variables such as fats and cost, fats and calories, or fats and LDLs. 

There is more about the Milky Way that scientists don't know than what they do know—that leaves a lot to discover! A thorough lesson presentation explores the components of the Milky Way Galaxy and their behaviors. 

Fertilizer can mean the difference between a profit and a loss. Scholars use an online interactive to explore the effects of fertilizing in agriculture. Given information about the nitrogen levels in the soil, they decide the fertilizer...

Properties of water make it essential for the life of marine species. Learners complete an online game to answer questions about the role water fulfills for organisms in ocean habitats. The game emphasizes the properties of water and how...

Chart ecological community interactions and answer questions about niche, defenses, trophic structure, and succession. This community ecology worksheet provides a general overview of the interactions that occur among organisms that share...

Why are greenhouse gases called greenhouse gases? Young Earth scientists learn about greenhouse gases though experimentation in the second installment of a 3-part series. They use lamps to model radiant energy as well...

Students research population and food consumption rates for different areas of the world.

What is the difference between accuracy and precision? This learning exercise has students define the terms accuracy and precision, and compare bulleye diagrams to find examples of both. Students analyze given data and determine the...

Sixth graders answer questions about "From a Railway Carriage." They discuss different poetical forms. They work together to write a poem about travel.

Students compare the pressure of water at different depths and gain an understanding of how increased water might affect animals living in deeper waters. They participate in an experiment to show that depth, not volume, affects water...

Almost 200 slides make this a vast collection! It is a quirky collection, titled "Marine Fisheries Management," but having little to do with that occupation. What you will find are two-toned blue backgrounds with no pictures, but a few...

Students examine how the mass of water can affect sound vibrations.

Learners examine the settlement patterns of world cities. In groups, they are given a region of the world and asked to create a city in the location. They are given a set of characteristics of the city and determine what would be found...

In this chemistry review worksheet, students practice using Avogadro's number, calculating number of moles, and using the gas laws. This worksheet has 39 multiple choice questions.

Discovery of microwaves and other trivia starting this PowerPoint will help interest your class in the application and behavior of these radio waves. Great images to show real-life experiments and equipment help understanding of how the...

Starting with definitions of empirical and molecular formulas, this slide show guides pupils through the ways to calculate and produce chemical formulas as percentages and molar ratios. A number of examples are given for viewers to try...

Pupils explain some of the topographical features of China's landscape. They view a Chinese landscape and discuss their view of the harmony between man and nature, then create their own karst mountain scene.

Students observe, over time, microbes such as amoebas, protozoa, rotifers and insect larva. They create a hay infusion culture using pond water then sample and record organisms found over a two week period.

Upper graders practice their estimation skills by observing different objects then making their best guess without using measuring instruments. Pupils are asked to estimate mass, length, volume, and area.

Using a magnifier, mini marine biologists examine the barbules of a bird feather. They swirl the it into a mixture of oil and water and then re-examine the feather. After the activity, discuss how the oily feathers pose a problem to...

Learners study the geography of Africa through the use of maps. They locate, distinguish, and describe the relationships among varying regional and global patterns of geographic phenomena such as landforms, climate, and natural resources.

As the title implies, this is a list of vocabulary terms relating to water monitoring. If your ecology class is learning about how to test water quality, this will be an appropriate reference sheet for them. As a bonus, if you live in...

Learners will determine the direction of Earth's rotation as viewed from the north and south if they were suspended out in space. They will model how the rotation of the Earth causes currents to be deflected in different directions for...
