Students identify that yeast are a single celled fungi that are a great model organism for studying respiration in the classroom. They also fill the bulb of a disposable pipet (eyedropper) with yeast, then submerge the pipet in a test...

Pupils investigate the pH of rain water in this earth science lesson. They collect rain water from their area and explore the pH when lime stone is added, then they will use the data collected to conjecture as to the effect of acid rain...

Learners experiment to determine ways different types of insulation materials work. In this animal adaptation lesson, they make hand coverings from plastic bags, shortening, feathers, and wool. They observe effects of these insulating...

Young scholars locate Lake Mead, then read a news article about Lake Mead drying up and how that would effect water and power supplies to the region. In this current events lesson, the teacher introduces the article with a map and...

Students will explore the animals and people living in the Arctic. In this science activity, students locate Alaska on a globe, discuss its climate and geographical features, and identify common arctic animals. Students complete the...

Students examine bread for microbes. In this mold growth lesson, students compare a slice of bread with saliva, a slice of bread with water and a slice of bread with mayonnaise to see which grows mold first. Students record their results.

Third graders explore the work of Daniel Bernoulli through experiment and background information.  In this Bernoulli lesson, 3rd graders participate in air pressure experiments. Students record their observations of the...

Students analyze data and determine an appropriate concrete mixture. In this technical solutions lesson, students discuss weighted objectives, review sample scenarios, and rate concrete recipes to identify how well water infiltrates....

Students determine the contact angle of water on different surfaces. In this physics lesson, students calculate their percent error using a mathematical formula. They explain the advantages of using non-wetting surface for certain...

Food preparation that supports the concepts of adding fiber and water to the diet. Identify fiber, its sources and functions. National Standard 14.2.1 Identify the function of fiber Identify cellulose - non digestible fiber Discuss the...

Students take a quick examine part of the water cycle, and the combined gas laws. The lesson lead them through the conditions necessary for cloud formation and allow them to create clouds in three different hands-on activities.

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...

Students observe beakers of water that contain different amounts of a mystery chemical. They discuss how each amount of the chemical might affect them if the chemical was beneficial or harmful to their bodies.

Students design and create their own heart valves out of a variety of materials. Their heart valves are one way valves designed for water flowing through a tube representing blood moving through the heart.

Students develop simple observations. They observe bleeding of colored inks with water, to understand mixtures, and to make generalized inferences from their observations.

Students consider that under certain conditions in nature tend to remain the same or move toward a balance. They observe populations and determine the functions (e.g., de-composers, producers, consumers) they serve in an ecosystem. They...

Students view and analyze buoy, satellite, temperature vs depth data to study about ocean circulation and how is related to atmospheric circulation. They read and interpret satellite image data related to: Surface wind speeds, Wave...

Students identify habitat elements. They create a habitat in a backyard, on a balcony, at a workplace, or in a schoolyard and provide the four basic requirements of wildlife survival (food, water, cover, and places to raise young). They...

Students understand the dynamics of acid rain and its impact on the living and non-living environment. They hypothesize how acid rain affects water pH levels in two lake systems with differing watershed features.

In this mixture learning exercise, students fill two test tubes with water and add starch to one and salt to the other. They stir the solutions and observe their appearance. They answer four questions about their mixtures and determine...

Students test the stickiness of natural substances. In this adhesion as a property of matter lesson, students build a tool to test the adhesion of natural "glues" such as honey, peanut butter, flour and water paste, and jelly. Students...

In these discovering if an ice cube and an orange or lemon will float in water worksheets, students conduct the two experiments, record the results, and answer questions. Students write 18 short answers.

Students estimate measurements in real world problem situations. For this estimation lesson, students read the book Pancakes, Pancakes and estimate how many cups equal a pint, quart, and gallon. Students test their estimations by...

Students design and create packaging material for food. In this snack attack lesson, students design a package to protect a food item from heat and water. Students consider costs of materials, design, and test the package to see if it is...
