High schoolers conduct a series of experiments to investigate density, buoyancy and climate. In this math lesson, pupils design and build a hot air balloon to demonstrate convection. They research and write a paper about solar chimneys.

Young scientists identify erosion, explain the causes of erosion, and name some techniques that can slow the process of erosion. Learners are divided up into groups of four and perform a simulation of soil erosion in class. The...

Sixth graders use various resources to locate information for a database (name of planets, diameter of planets, etc.). They enter the data onto a prepared data grid. Use of Access to sort data is accented within this activity. Students...

Learners perform an experiment to measure the density of tap water vs. salt water.

NFL football in science class? Yes, please! In an engaging and motivating three-day lesson, kids take a look at their own nutritional habits and needs compared to those of an NFL player, then experiment with the effects of hydration on...

Here is a comprehensive method for assessing chemistry learners' knowledge; have them approach two laboratory problems, plan their methods of solving each, and then actually carry out the experiments to find the answers. Both the...

Complete a survey on genetics and the mechanics of heredity.and review the list of human traits observed. Practice interviews are conducted with each other so that noone feels unconformable if they don't have one trait or another. One...

Two laboratory problems are put forth for chemistry students. They are to plan and carry out an experiment that will answer each of the questions. The first asks them to investigate a relationship between the surface area of a potato and...

Information is provided on Gray's Reef, Florida Keys, and Flower Garden Banks marine sanctuaries. Young marine biologists then visit the FishBase and REEF databases to collect fish species information for each location. They then...

Has your class ever wondered how animals and scientists stay warm in the Polar Regions? Kids will investigate to understand the three types of heat transfer and how heat transfer affects those trying to stay toasty in sub-zero...

Teaching is a balancing act! Keep things on an even keel with a comprehensive equilibrium lesson plan. The resource covers reversible and irreversible reactions, Le Chatelier's Principle, and the industrial applications of equilibrium...

Students seek scientific and technological solutions to envrionmental problems. They record class activities in a journal. They identify relationships among living things and their environments.

Kids consider how the body functions and moves, how each structure has a specific movement and purpose. They apply that idea as they construct a sculptural piece that moves. For inspiration they look to the work of Alexander Calder,...

Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...

Household materials can be used for more than cleaning! In this collaborative experiment, emerging chemists use products such as vinegar and liquid antacid to explore chemical reactions that commonly occur in the human body.

Whose home is it anyway? Design teams plan a housing development in which they must also protect a native species. The teams consist of a project manager, civil engineer, environmental engineer, and graphic designer. Teams present their...

Let there be light. The last installment of a seven-part series has pupils conduct an experiment on light attenuation through different numbers of transparency sheets. They then relate the results back to how X-rays measure bone density.

How does the dirt get out of your drinking water? A hands-on activity introduces the use of flocculants to help clear solid particles out of water. The plan walks learners through the process of setting up an experiment that...

Investigate thermoset polymers through experimentation. In an effort to determine the strongest, most flexible mixture, groups conduct an experiment on different-ratio epoxy-amine polymers to finish the set of two lessons.

Let's hope that your soap is doing what it's supposed to! The second of six installments in the Cells unit has scholars perform an experiment cultivating bacteria in Petri dishes. They test soaps and detergents to see which is most...

High schoolers conduct an experiment using the reaction of hydrogen and oxygen. After pairs balance the chemical equation for making water, they mix different ratios of hydrogen and oxygen in a chemical reaction. Classmates...

Although designed for a foods lab, the information in this resource might be just the thing for your own recipe notebook. Illustrated, step-by-step directions for making the perfect omelet, egg-citing puzzles, games, and even...

Lost an electron? You should keep an ion them. Young chemists learn qualitative analysis in the second lesson plan of an 11-part chemistry series. After observing reactions of simple salts, the teacher provides pupils with unknown...

Heat up your lessons on boiling points. The resource provides a three-part activity: first, groups find the boiling point of solutions; second, they create boiling point curves for salt and sugar solutions; and third, they mix a solution...
