Students conduct a series of experiments in which they explore chemical reactions. They detect chemical changes by observing how physical properties change when two different chemicals are combined. They list and describe the reactants...

Students create a thunderstorm by putting ice cubes and food coloring into a container and observe what happens to the food coloring. In this thunderstorm lesson plan, students discuss the cause and effects of thunderstorms and then...

Students examine macro-invertebrates in order to better understand their link to the food web. Working in groups, they record observations of several areas of a stream or river, collect samples from the river bottom, and identify the...

Students review information they have gathered from previous lessons. They create their own experiments and carry them out. They reflect on the project as a whole.

Students build tools to help track the weather. In this weather lesson, students follow directions to build a rain gauge, barometer and hair hygrometer.

Pupils explore matter by conducting an in-class experiment. They experiment with water's various forms by melting and freezing water, identifying its new shape. These observations are recorded to supplement later discussion. They also...

Students discuss methods of transportation they use and create a trip tally to determine which methods they use the most.

Students prepare a classroom weathercast and present a broadcast.

This laboratory activity is valuable practice in comparing features of different organisms. You could use it to introduce junior biologists to protozoans. The materials and procudures for the learners are simple, and analysis...

Students work on the development of observation skills and seeing how they can be used in different contexts. The lesson is good for helping the beginner and novice, along with encouraging and reminding the expert observer of right...

Students interpret a poem before completing activities to distinguish observations and interpretations. They examine how personal background can influence how a person interpreters what they observe.

Third graders review the scientific method and how and in which steps scientists use observations and measurements. Then as a class, they hypothesize which ramp will send the car the farthest. They break into groups and send cars down a...

In this ocean life worksheet, students observe the plants, animals, human activity, park rules/local laws, at a specific location. Students also observe any activity in neighborhoods, the water sources for the area, the water uses, and...

Second graders compare and contrast animate and inanimate objects. In this environmental science lesson, 2nd graders create simple food webs. They observe their environment and create a collage about it.

Students grow crystals in the lab using solutions. In this crystals lesson plan, students set up a crystal growing apparatus using a sugar solution with a thread attached to a piece of copper wire that is inserted in the solution....

Students explore animals that live in trees. In this nature and biology instructional activity, students go outdoors and make observations about animals and their unique body parts that help them to live in trees. Students create...

Students produce a newspaper describing the times during which Charles Darwin introduced the theory of natural selection. In this evolution lesson, students make observations and explore the role of observation in Charles Darwin's work....

Explorers of the environment construct a dichotomous key for a variety of organisms and design a key to classify Galapagos animals based on descriptions and images. The lesson includes a link to an animal gallery and the worksheet for...

Students investigate the effects of adding or removing a reactant or a product on chemical equilibrium. In this equilibrium lesson plan, students add or remove ions to solutions to determine the effects on equilibrium. They make...

Students investigate the importance of water in an environment with living things. in this water conditions lesson plan, students soak radish sees in water, vinegar, soap and alcohol. Students remove the seeds, store them for a few days...

In this chemical reactions worksheet, students experiment with reactions between 4 different metals with water, acid and air. Students make observations of copper, iron, zinc and magnesium with water, acid and air. They write an analysis...

In this soil porosity worksheet, students experiment with four types of soil. They fill separate cups with each soil type and pour water in measuring the amount it takes to saturate the soil. They make observations and compare their data...
