Students experience and visualize first hand the importance of proper hand washing through a hand washing experiment with different temperatures of water and with a different length of time to wash. They prevent food-borne illness and...

Students explore air pollution. In this ecology and air pollution lesson, students perform an experiment in which a Vaseline coated lid is placed inside and outside the classroom. Students make predictions and then record what they see...

Eleventh graders identify, create and solve word problems involving inverse variation. In this algebra lesson, 11th graders solve problems using direct, inverse and joint variation. They identify problems using these methods.

Students investigate and measure using the metric and customary units. In this math lesson, students investigate which method is used most worldwide, the metric or the customary. They convert from unit to the other.  

Middle schoolers convert U.S. customary measurements into larger or smaller units with the help of conversion charts. They are explained that they are going to use conversion charts in problem solving situations. Pupils use a...

A terrific lesson focused on the design process. It begins with a presentation, "Design: Solve a Problem," which lists the steps of the process and then introduces the specific challenge: to build a device that measures wind speed....

If you need an array of worksheets to augment your science lessons, peruse a collection of assignments that is sure to fit your needs. With topics such as metric conversion, the scientific method, textbook features, research skills,...

Tired of waiting for hot water? Groups of three determine the efficiency of an electric water-heating device. They calculate the amount of energy it takes to heat the water and the theoretical amount of energy required to heat the water....

Which modification is the best? Using the scientific method, pairs determine the effects of each control surface on the distance of a glider's flight. The activity, section 16 in a 22-part unit on aviation, allows pupils to gain a better...

Forget your local meteorologist — build your own barometer and keep track of the weather with an activity that provides directions to build a barometer out of a narrow necked bottle, a glass, and some water. Using their barometer,...

Climb up the staircase of engineering knowledge. After watching a video of a carpenter measuring out steps for a set of stairs, pupils learn about the terminology and regulations involving stairs. They see how to use a rule of thumb when...

Welcome to Biology! Introduce pupils to a subject conceptualized by Aristotle in 300 BC through a presentation and worksheet. It covers the themes of biology, characteristics of life, the scientific method, microscopes, and measurements.

How random is random? Demonstrate the different random sampling methods using a hands-on activity. Pupils use various sampling techniques to choose a random sample of elements from the periodic table. They use the different samples to...

Meet me in the tunnels. Scholars choose a tunnel entrance and mark it on their side of the cardboard. They describe the location to their partners and see if they can guess each other's locations. Punching a hole through the cardboard...

Conduct an experiment to determine the accuracy of pedometers versus pedometer apps. Class members collect data from each device, analyze the data using a hypothesis test, and determine if there is a significant difference...

Give young scientists a new appreciation of fresh, clean drinking water. After learning about the ways astronauts recycle their air and water, your class will work in small groups creating and testing their very own water...

Collections of data represented in stem and leaf plots are organized by young statisticians as they embark some math engaging activities.

Turn up the heat! Young mathematicians develop models to represent different climates and collect temperature data. They analyze the data with regression and residual applications. Using that information, they make conclusions about...

Data distributions can be compared in terms of center, variability, and shape. Two exploratory challenges present data in two different displays to compare. The displays of histograms and box plots require different comparisons based...

What did gender have to do with the survival rates of the Donner Party? Using comparative box plots, classes compare the ages of the survivors and nonsurvivors. Using the same method, individuals make conclusions about the...

In this scientific method worksheet, students read about the steps of the scientific method, ways to measure mass and volume and how to read a meniscus. Students use the scientific method to determine if an object is a liquid or a solid...

In this measuring worksheet, students answer 10 questions about the scientific method, scientific law, hypotheses and data. They also answer 2 questions about biomes and wetlands.

Students study wind speed and collect wind speed data. In this wind speed lesson, students visit a website to learn about the local wind speed forecast for their week. Students discuss wind and wind speed. Students collect wind speed...

Students role several balls of different weights down a ramp and into a paper cup and record how far each ball made the paper cup move. They then answer questions that help them analyze their results and reinforce the idea that energy...
