Where is HIV/AIDS most prevalent and what are the current trends regarding HIV? Have groups work together to map the world's HIV/AIDS rates, then create a class map with all the data. Lesson includes cross-disciplinary concepts including...

In an introductory activity, youngsters take a pre-assessment quiz, get a grasp of a gram of mass, and then estimate the mass of microorganisms that live within a human body. Using Glo Germ™, a material that allows you to simulate the...

Life science learners need to be able to use a microscope. With this comprehensive resource, they first experience how lenses and magnification work, and then get familiar with using a compound microscope. Tremendous background...

Though it isn't a novel activity to prepare onion cell and Elodea plant cell slides as examples of cells in a microbiology unit, this resource will leave you thoroughly prepared. As pupils examine the slides that they prepare, they draw...

As the great and hilarious Tim Minchin once said, "Science is simply the word we use to describe a method of organizing our curiosity." Science is more than just a guess; it is based on questions, observations, and evidence. High...

According to the movie Wildcats, "It's the sport of kings, better than diamond rings, football!" It is also, however, the sport of severe concussions and ongoing blows to the head. In order to keep our Seahawks soaring and Broncos...

Although it was published in the year 2000, this chemistry assignment is ideal for practicing the application of Charles' law. There are seven real-world problems to solve, and plenty of space provided for doing so. Add this to your...

Water may appear to be crystal clear, but there could be dissolved substances present. Lab groups make a one-part-per-million of a food coloring solution to demonstrate this concept. As part of an outstanding unit about water, this...

Ecology candidates culture pond water organisms over a few days time, then they experiment to find out how increasing nutrients affects the population. As part of a unit on water, this exploration gives your class an understanding of how...

Elevate young scientists' skills with unit conversion using the stair-step method. Detailed instructions and a neat stair-step diagram are on the first page. Four pages of practice problems follow, mostly with real-world applications....

Here is a comprehensive stereochemistry exam for advanced chemistry kids. In the 101 problems, there are short answer, multiple choice, and drawing questions. Topics include chiral and achiral molecules, enantiomers and diastereomers,...

Using an auger, start-up soil scientists bore a core of soil. They examine the sample and record the temperature at three depths in the borehole. This is an attractive activity sheet that succinctly guides your earth science class...

Aspiring astronomers assess the inner planets using this handout. They read about the characteristics of each, noting that all four of them have rocky surfaces. Rotation and revolution are introduced, including Venus' retrograde...

After reading about how the sun gets its energy, and about the layers and features of the sun's atmosphere, heliologists complete a comprehension worksheet. On it, they label features on a diagram of the sun and match terms from the...

What a festive way to examine what happens to the heart in different gravitational situations! Small groups place a water-filled balloon in different locations (on a table top, in a tub of water, and held in a vertical position), drawing...

Get close up and personal with a drop of water to discover how the polarity of its molecules affect its behavior. Elementary hydrologists split and combine water droplets, and also compare them to drops of oil. Much neater than placing a...

One of water's claims to fame is as the universal solvent. Young physical scientists experiment to discover which materials dissolve in this special compound. You could never be more prepared for teaching this lesson than by using this...

Small groups place sand and ice in a covered box, place the box in the sunlight, then observe as evaporation, condensation, and precipitation occur. These models serve as miniature water cycles and demonstrations of the three phases of...

Let's heat things up! This simple experiment demonstrates for students the important role the sun plays in providing the earth with energy. Place one cup of water in direct sunlight and one in shade, then take measurements in order to...

Uncover the science behind the beautiful phenomena of rainbows with a simple demonstration. Shine light through different-sized containers of water as young scientists learn that rainbows occur when visible light is split up into its...

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...
