Learners investigate the relationship between the Fahrenheit and Celsius temperature scales. Given two data points, they construct a linear function to describe the relationship, find the inverse of the function, and make observations...

Plankton are so abundant in the ocean they outweigh all of the animals in the sea. In this three day activity, groups discuss and become familiar with plankton, capture females, and look for egg production on day three. 

Don't let all your hard work go up in smoke. Pupils conduct an experiment to see the harmful effects of cigarette smoke. They observe how smoke changes the color of white wool and an indicator solution.

Students make observations of ice as it melts. In this phase change lesson, students observe ice as it melts in a cup. They discuss their observations and place the cup of water into a freezer to change it back into ice.

Students investigate the concept of density by observing demonstrations. In this density lesson plan, students make observations while the teacher demonstrates the Cartesian diver, a density column, a candle trough, a wave bottle, an...

Students explore the process of seed germination. In this botany lesson, students complete an experiment with seeds. Students observe soaked and dry seeds. Students allow the seeds to germinate and make observations during this time....

For this thermal decomposition of calcium carbonate learning exercise, students perform three experiments on calcium carbonate, make observations, and write the equations for each reaction. Students explain in detail what happened at...

Fifth graders utilize basic physics concepts to calculate speed of an object set in motion from various heights. In this basic physics instructional activity, 5th graders make observations, calculations, record data, and conclusions...

Students compare seeds with seedlings. In this life science lesson, students make observations of seedlings and the seeds they grew from, paying special attention to the roots. Lesson includes extension activities.

Students investigate 3 types of soap. In this properties of soaps lesson plan, students test soap with pepper and observe the reaction between the two. They make observations of the 3 types of soaps and make a chart to compare each. They...

Students investigate the concept of diffusion through a membrane. They do this through the conduction of a simple experiment. Students make observations while determining if the smell of different chemicals seeps through the balloon...

In this chemical and physical change worksheet, learners conduct a variety of experiments with unknown solutions and make observations. Students determine if the properties of the solutions have changed and if there is...

Learners investigate the effects of ground water contamination. In this ground water contamination lesson plan, students create a mini well and simulate ground water flow through the well with a contaminate (food coloring). They make...

Students observe the difference between degradable and non-degradable wastes. They create their own landfill in a jar by adding four or five pieces of garbage and then covering it with dirt and water. They make observations on what they...

Primaries explore the concepts of observation and inference. Given a set of six sealed boxes, children lift, tip, or gently shake in order to make observations about what is inside. The lesson plan gives preparation instructions in...

Students investigate magnetism. In this physics lesson plan, students create a KWL chart about magnetism and research various suggested websites to find out more about magnetism. Students log on to the "BrainPOP" website and view a short...

In this rusting, burning and oxygen worksheet, students read about chemical reactions and are given diagrams of a rusting bicycle, a burning candle, and a variety of chemical changes. Students make observations and explain the chemical...

Young scholars create fossils to understand how scientists learn about dinosaurs.  In this dinosaur lesson, students mix ingredients to make dough and put in objects that can make impressions. Young scholars let fossil dry...

Students build a telescope and give quantification of its magnification and field of view while making observations regarding images. In this telescope lesson, students use a simple lens to project a scene and examine various telescope...

Middle schoolers investigate the force of gravity and how it effects different objects that are put into acceleration when applied the experiment of free falling. They drop different objects that have a variety of masses and some that...

Students work in groups with copies of the three photo images provided with the lesson. They make observations about mussels and clams. Students discuss reasons scientists use a representative sample of a population rather than the...

Students explore chemical cahnges and the effect of temperature on chemical mixturees, They make observations of the behavior and appearance of certain chemical mixtures and reactions.

Students conduct a scientific investigation about the formation of stalactites and stalagmites. They conduct an experiment to reproduce them in the lab environment. Students make observations over a period of time in order to see the...

Students examine the rotation of the Earth as it occurs in the 24 hour cycle. They use models of planets and the globe to make observations of movements made. Students brainstorm prior knowledge and then participate in a demonstration of...
