This is lesson 3 of 3 in the Goldilocks’ Café Just Right unit. This lesson focuses on systematic investigation on getting a cup of coffee to be the “just right” temperature and turbidity level. Students will use both the temperature probe and turbidity sensor and code using ScratchX during their investigation.

Come sail away with this STEM activity! Students will use hands-on inquiry to find out more about wind and its effect on sails. Through trial and error and based on data collected, students will design, build, and race their own vessel or "sailboat" across the boundless waters of a kiddie pool. Students should gain a better understanding of how moving water and air are sources of energy and can propel objects forward at varying rates of speed.

Type: Lesson Plan

This is a fun science lesson that teaches children about inherited animal behaviors through observation and direct instruction. Students then use their new skills to write a news article explaining what school might be like if teachers or students had different inherited and learned behaviors. This lesson can be integrated into reading and includes an opportunity for writing across the curriculum.

Water is essential for human health, but it can sometimes be contaminated. Water filtration can filter out contaminants and impurities making water much safer to consume. But what is the best way to filter water? Students will participate in a water filtration engineering challenge to try out different combinations of materials to find which works best. This lesson was developed by the Phillip and Patricia Frost Museum of Science with support from the Weo Foundation.

Type: Lesson Plan

In the lessons here, students exercise the observation skills that are essential to writing, visual art, and science. First, they try to use evocative language in describing pictures of birds from the Smithsonian's National Zoo. They go on to record observations and to make hypotheses as they follow the behavior of animals on the National Zoo's live webcams. They can watch the giant pandas, the tigers, the cheetahs, the gorillas, or any of a dozen other species.

Discover the methods scientists use to solve problems, answer questions, and make discoveries in this interactive tutorial.

Type: Original Student Tutorial

Students correlate the weight and water displacement of various balls. They then apply their understanding to an additional situation. The task assesses students' abilities to make simple observations, collect data, make generalized inferences from their observations, and apply their understanding to an additional situation.

This task is designed to take students approximately 45 minutes to complete.

Type: Problem-Solving Task

The webmaster for the ENSI web site (), a popular repository for Nature of Science Lessons, describes some educational philosophy about teaching the Nature of Science, including dispelling some teacher-held misconceptions.

Type: Professional Development

In this unit, students will first do research and study the Law of Conservation of Mass and learn how to form a hypothesis. After they learn how to form a hypothesis, they will use balance beams to measure clay and crayons.

Type: Unit/Lesson Sequence

In this unit, students learn about weathering and erosion (and different types of weathering and erosion) through different models and activities. An engineering design competition asks students to synthesize knowledge about erosion to create an erosion-blocking process/product for the Atlantic Coast.

Type: Unit/Lesson Sequence

In this lesson students will learn about pollution and its effects. They will learn in depth about pesticides and see its harmful effects that they might not have realized at first. The students will simulate a landfill and see what objects will decompose and which objects won't. They will create their own solutions to an oil spill and test to see which solution is the most effective. The students will observe the effects oil has on water birds. Through this they will determine the long term damage done by an oil spill.

Type: Unit/Lesson Sequence

Watch a demonstration of an experiment which tests the effectiveness of two different insulators. The participants will demonstrate their thinking as they run an experiment, identify variables and collect data.
