Third graders adopt a deciduous tree in September, and begin regular observations of their tree. They create a timeline to show how leaves change color and conduct a science experiment to illustrate color change.

In this human cells activity, 7th graders complete a science experiment using human cheek cells. Students sketch the cells at high and lower power and label the cell nucleus, cytoplasm, and cell membrane.

Learners create a drawing of what an astronomer looks like. They explore their own assumptions of those who work in the sciences.

Students experiment with swirling sand and stone inside a bottle for this assignment. They predict what the final design will turn out to look like. Students after observing the bottle still, turn the bottle upside-down and experience...

Pupils examine the concepts of micelles, polarity, solubility, and properties of detergent in an experiment with milk, water, and food coloring. Students complete a Take-Home Challenge in which they experiment with the behavior of food...

Students use a model experiment to complete an experiment on yeast. In groups, they identify the independent and dependent variables and use the scientific method to complete the activity. They record their observations and discuss them...

Students explore energy by researching fuel usage on Earth. For this fossil fuel lesson, students define fossil fuels, the energy created by burning them, and the impact on the environment when using them. Students conduct pollution...

What is a scientific investigation? What are the various parts of an experiment? This worksheet provides a basic review of most key terms: scientific method, manipulated variable, responding variable, hypothesis, controlled variable,...

Young science learners construct a greenhouse out of a plastic bottle. They use a nail to punch a hole through which a thermometer will be inserted to monitor the temperature. This simple experiment easily demonstrates the greenhouse...

After reading about the Lake Erie water snake and the change in its population after the introduction of the round goby in 1990, young ecologists graph water snake diet data. They analyze the data and answer 10 questions based on their...

Bycatch is the unwanted and discarded marine life caught during commercial fishing. Young marine scientists review bycatch litigation and analyze graphs of bycatch data and answer questions about it. This raises awareness while...

Students explore how water moves through soil. They experiment with different soil types and record their findings.

Students examine the Dust Bowl and the effects of farming practices in the early 20th century. They read a handout, and conduct and discuss two experiments simulating soil erosion.

Students discover that composting helps reduce landfill waste and is good for the soil. They explore the techniques of composting through a variety of media, art activities and hands-on experience.

Analyze a Happy Meal™ for nutrient content and calories. Blend the contents into "McMush" and use Biuret's solution to test for protein content. There are a few problems with the lesson plan: the resource links are no longer...

Students create an ornament with their photo inside of it. To create the personal memento, students observe demonstrations and follow directions. Students experience making a craft and giving the memento to a family member.

Discover the calorie content of foods by observing how much heat they produce in water. If you have a calculator-based laboratory (CBL™) insturment for collecting data, then this laboratory worksheet will not need any changes. If...

Students examine the effect of temperature on how often crickets chirp. In groups, they complete the experiment and answer lab discussion questions. They create a graph of temperatures and the amount of chirps and discuss the results.

How do sugar and salt affect celery's mass, width, and flexibility? Using simple household ingredients, young scientists will perform a controlled experiment to find out. The lab is scaffolded through a activity, but there are no other...

Students explore the value of land and the importance of conserving it as a limited resource. They observe a experiment where an apple represents the earth. From the demonstration, students visually see the fractions and percentages that...

Students experience and participate in "Riding the Water Cycle" with this lesson. They explore, analyze and study the role of reservoirs in maintaining a reliable supply of drinking water. Each student constructs a model of a reservoir.

Pupils, while utilizing a large wall map, experiment recording the annual precipitation for cities on the east and west sides of the Cascade Mountains. They discover that volcanic mountains do not have to erupt to affect the atmosphere.
