There is a solvent called aqua regis that can dissolve gold! After observing a solubility demonstration, groups receive four known crystals and one unknown. Based on the demo, they design an experiment to determine the identity of the...

When making sweet tea, why do people dissolve the sugar in hot tea instead of cold tea? The class discusses the previous lab and builds upon it. Working in groups, they design an experiment to determine how temperature affects the...

Pupils reseach the different types of soil erosion and ways to control it in this series of activities.

Young scholars review the meaning of control and variables, and state difference between dependent and independent variables. They complete a worksheet with the definitions and complete problems that show their understanding.

When going for distance, does it make a difference at what angle you launch the rocket? Teams of three launch foam rockets, varying the launch angle and determining how far they flew. After conducting the series of flights three times,...

Scholars find a pattern from a geometric sequence and write the formula for extending it. The worksheet includes a table to complete plus four analysis questions. It concludes with instructional implications for the teacher.

Learners complete a virtual lab to test for a corn mold that can lead to dangerous toxins. They walk through a detailed step-by-step procedure then see their findings. Throughout the activity, they learn how to use lab tools and practice...

Experimentally, come up with a study design. Learners hear about different types of study designs, observational studies, and experiments. They identify the subjects, response variable, treatment, and whether there was a cause and...

Which of the following can you survive without for the longest time: water, food, or a positive mental attitude? The answer may surprise you. Guide learners of all ages through games, activities, and discussions about surviving in the...

Guide learners through an experiment with a set of worksheets on the scientific method. Six steps prompt your class to ask questions, conduct research, form a hypothesis, test theories, analyze data, and report results.

Researchers think they have evidence of a new planet deep in our solar system that is the size of Neptune and orbits the sun far beyond Pluto. The orbit simulator shows the orbits of our well-known planets, as well as Pluto and the comet...

Over the course of 10 days, young scientists observe their cups of seed and soil—one that gets sun and water and one that gets no sun and only water. Then they reflect on the results of the experiment to determine if their hypothesis was...

For this biology worksheet, students take part in an examination of the graphic organizer to determine the different types of environments and how they effect the survival of microbes.

Learners collect and identify plant species from campus, create a home herbarium, and compare with the plant species from school.

Seventh graders learn about John Kellerman, a youngster who was born with Fetal Alcohol Syndrome. They learn how alcohol and pregnancy doesn't mix.

This interesting document suggests nine different activities for shedding light on photovoltaic cells. A bit of background information is furnished for you, as well as many, many resource links. Listed for each activity are a learning...

An outline walks your scientists through the steps of the scientific process. It begins by taking a general idea and developing a hypothesis based on related factors. Each investigator then plans a method for testing the hypothesis,...

Examine parts of an expression in this algebra lesson. Ninth graders identify the properties of the coefficient and their behavior to the graph. They graph the equation on a TI to see their results.

Research the impact that changes in biotic or abiotic factors might have on an ecosystem. Debate for or against the changes and take action in the community. This resource ideally follows stream studies that young ecologists may have...

Here is a complete activity in which young biologists or ecologists test the pH, dissolved oxygen, turbidity and temperature of stream water. The class visits an actual stream and makes observations of the site. They use scientific...

Explore the concept of systems of equations in two variables and use matrices to solve them. Young mathematicians enter coefficients and constants into a matrix and then solve using row reduction. Instructions on how to use the shortcut...

Three main factors determine the wave height experienced in the ocean. Scholars use a virtual simulator to alter wind speed, fetch, and duration. Each combination creates a unique wave measured in significant height.

The first in a six-lesson mini unit, all using M&Ms® candies, this physical science activity gets kids to observe a single piece and discover what happens when it is placed in a plate of water. The activity can be used to...

Did you know that if you wait long enough, the M on the outside of an M and M will float to the surface when submerged in water? Learners observe the sugar coating of an M and M while it is dissolving in water. They explain how this...
