Join the tree house detectives in learning about the processes of the water cycle, water conservation, water treatment, and water as a limited resource.

Young scientists explore the concept of surface tension at is applies to water. In this activity, learners use a dropper to place drops of water on a penny. Each group guesses how many drops a heads-up penny will hold, then conducts the...

In this ice and water worksheet, students read about the energy needed to transform ice to liquid water. Students solve 3 problems where they calculate the energy needed to melt ice given different scenarios in space.

Here is a planet worksheet in which learners read about organic molecules detected through spectral lines of the planet Osiris. They calculate the mass, the volume and the densities of common ingredients for planets including Osiris and...

Young scientists explore Earth elements by conducting an experiment. They define water vocabulary terms such as condensation and precipitation. In addition, they conduct a water experiment in which they build a terrarium, so they can...

In this counting atoms in a molecule worksheet, learners read about the molecule propanal that was discovered by the giant radio telescope in the Milky Way Galaxy. Students solve 6 problems where they find the number of atoms in the...

In this moon worksheet, students read about the data collected from the Deep Impact/EPOXI and Cassini missions to the moon that have detected the presence of hydroxyl molecules under the moon's polar craters. Students solve 4 problems...

Responsible farming is important for maintaining natural resources. Eager scientists complete a WebQuest to explore what happens to nitrogen when it enters the soil. They learn about the chemical makeup of nitrogen-based molecules...

Students estimate the size of a molecule of oleic acid. They conduct an experiment using chalk dust, water, and oleic acid, solve various calculations, and answer discussion questions.

Students measure the amount of surface tension using a balance scale after a classroom demonstration students diagram the appearance of several liquids and label them.

Students study the vocabulary of the states of matter. In this states of matter vocabulary lesson plan, students investigate and study the meaning of the words solid, liquid, and gas. They experience demonstration lessons that give them...

In this fractions in chemistry learning exercise, students solve 2 problems where they state all the answers as simple fractions or integers. They determine ratios of molecules in gasoline and they find ratio of molecules in the creation...

Young scholars identify diffusion and its processes through experimentation and calculations. They also use a CBL and conductivity probe to measure the conductivity of various solutions and study the effect of concentration gradients on...

Finding a balance between too much protein and not enough doesn't have to be a guessing game. Young scientists use an interactive lesson to learn how to calculate protein content in cattle feed and how to mix feed to create the ideal...

Although this is a science lesson, it can be adapted to help meet Common Core standards in math as well. Starting scientists describe physical properties of objects and explore three forms of water. To address the Common Core, they can...

Students investigate the relationship between volume and mass in different liquids such as vegetable oil, rubbing alcohol and water. They measure the mass of several different volumes of each liquid and then graph the results as well as...

Eighth graders experiment to determine the number of drops of water a heads up penny hold. They create a stem and leaf graph of the class results and use the data for further experimentation on a tails up penny.

Help learners determine the rate of change for the temperature of sand. They will collect data on the temperature of wet and dry sand over time with a heat lamp overhead. Then make a scatter plot of the data and find a linear model to...

In this scientific notation worksheet, 9th graders solve and complete 8 various problems related to exponents and writing scientific notation of numbers. First, they write whole numbers, decimals, and other types of numbers in scientific...

Students investigate air by participating in a class experiment. In this matter measurement lesson, students identify air as a gas which consists of mass. Students utilize a windsock or balloon to measure oxygen and explore it's true...

In this parts per hundred activity, learners read about describing components of a population by parts per a given number such as 100, 100 or 1 million. Students are given 6 problems to calculate the parts per hundred for each sample given.

Fifth graders use modern technologies which allow them to gain a new, dynamic, and intersting understanding of themselves, their community, and the world. They focus on environmental education and the effect of the environment on plant...

Taking the notion of symmetry to the next level, this looks at combining rotation and translation symmetry to build spiral symmetry in three dimensions. Using the Zome modeling system and an instructor’s guidance, geometers try to build...

In this ratio and proportion worksheet, learners solve 22 short answer and multiple choice problems.  Students use rates, proportions, and ratios to solve each problem.
