Students test factors that may affect the rate at which sugar dissolve in water. They conduct two studies: One is to test the effect of temperature on the rate of solvation and the other is to test a factor which Students come up with...

In this chemistry learning exercise, students create new and true statements while replacing false ones in order to properly define parts of the concept of bonding.

Students watch a demonstration with a balloon filled with water being buried in a milk container that has been cut length wise and filled with sand. Students are told that there is an underground storage tank filled with a contaminate...

Tenth graders test their saliva for enzyme activity. In this enzyme lesson, 10th graders conduct an experiment to test the enzymatic activity of their saliva. They relate the lack of certain digestive enzymes with alcoholism.

In this acids and bases worksheet, students read about the differences between acids and bases and then complete a table comparing the characteristics of both. Then students determine if the given statements describe an acid, base, or...

For this outcome science 4 worksheet, students apply scientific knowledge to answer and calculate a variety of questions. Students research the answer to several questions using the websites suggested.

Students investigate water ways by conducting an experiment with classmates.  In this natural resources lesson, students define a watershed and identify where large ones are located within the United States.  Students utilize...

Students examine the impact of the physical and chemical properties of milk and its use as an important food.

Ninth graders examine the Periodic Table. In this element instructional activity, 9th graders observe the chemical reactivity of elements. They graph the properties and discuss the trend in the group and period of elements. The students...

Students investigate climate change and how the properties of carbon dioxide and methane play a part.  In this climate lesson students use a chemical reaction to trap CO2 and methane.

Students determine the density of a material created in the laboratory and observe physical and chemical changes. They engage in a lab activity, and answer questions on a worksheet imbedded in this plan.

Students examine the different properties that affect water quality.  In this pollution instructional activity students play a game, complete a hands on activity and computer lab. 

In this chemistry review worksheet, students answer a variety of questions about matter, elements, the kinetic theory, chemical and physical properties and the distillation process. They complete a concept map about matter.

Students construct their own rocket-powered boat called an "aqua-thruster." These aqua-thrusters will be made from a film canister and will use carbon dioxide gas - produced from a chemical reaction between an antacid tablet and water -...

Students examine a crushed rock and sort the minerals they find in that rock by color and other properties.

Students differentiate physical and chemical change. In this chemistry lesson, students list examples of those changes. They apply what they learned in a Jeopardy style team game.

For this chemistry worksheet, students fill in the blanks with the correct word from the word list. They examine the arrangement of elements in the periodic table.

Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

Water, one of the basic needs of humans, is found in all three states of matter on Earth; no other planet—that we know of—possesses this quality. Here is a unit that allows learners to explore through experimentation what it...

Sometimes, despite the best laid plans, the unexpected will occur. Learners witness this firsthand as they carefully design an experiment to determine the time needed for ice to melt in salt water or pure water. They uncover facts not...

Aqua regia, or royal water in Latin, is a solvent that can dissolve solid gold and platinum into a solution. Activity nine in a series of 36 allows classes to learn, through readings and answering questions, what a solution is and the...

Polymers are an important part of our day-to-day lives, but how much do your pupils know about them? Learn the basics and beyond in a series of activities designed to build skills in observation, planning, organic chemistry, and bonding.

Carbon, the base for all organic compounds, exists in nature in its purest form as graphite or diamonds. The 25th lesson in a series of 36 teaches pupils the nomenclature of organic compounds. Learners read about how to use the IUPAC...

Science rocks! Explore three types of rocks and the rock cycle with an igneous rocks experiment. Pupils discuss textures, composition, and learn how melts are formed from the Earth's crust. They weigh materials using a scientific scale...
