Too much material will weigh you down. The sixth segment in a series of 22 highlights how weight affects a plane. Pupils learn that engineers take the properties of materials, including weight, when designing something. 

How do you calculate your Body Mass Index, and why is this information a valuable indicator of health? Class members discover not only what BMI is and practice calculating it using the height and weight of six fictitious individuals, but...

How do you convert from one measurement to another? Pupils use unit rates to convert measurements from one unit to another in the 21st segment in a 29-part series. They convert within the same system to solve length, capacity,...

Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

Planning a unit on simple machines? Save some time and energy with this collection of lessons and activities that explores how these devices are used in the real world to make life a little easier. 

High schoolers participate in a qualitative discussion of the distinction between weight and mass, followed by a description of astronaut mass measurements in a zero-g environment.

Beware the falling fruit. Scholars design and build parachutes that can help protect fruit as it falls. They test out their creations, learning about gravity, weight, air resistance, and measurement concepts along the way.

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson plan, scholars explore buoyancy and the properties of air and water. They test cups to see...

What's the moral of this story? Units save lives! Teach measurement conversion through storytelling in a quick math-based lesson. Young scientists learn how one country's decision to swap from imperial to metric standard units caused an...

Students discuss how weight is directly related to gravitational force on a planet. Students then choose Space Traveler as companion and compute how much their guide weighs on various planets, based on each planet's relative surface...

Young scholars see the difference between weight and mass when they examine the method of measuring each of them.

Students use graph paper to construct a graph and determine the slope of a straight line. They determine the weight (mass) of paper clips with a pan balance. Pupils weigh an unknown number of paper clips, and to interpret the graph to...

Learners measure how much mass is worn away during 15-20 minutes of shaking. They shake rocks for 15-20 minutes to simulate stream erosion. Students listen to music as they shake their rocks. They weigh out 100 grams of marble chips....

Applying this metric activity, mathematicians will provide standard metric units of measurement, identify the largest and best way to measure items using the metric system, and convert units using King Henry.

Young scholars observe the 'pouring' of a gas. They compare the masses (weights) and densities of two gases. Pupils define the following terms: matter, mass, and density. Students answer questions after watching the demonstration.

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Young scholars examine how the mass of water can affect sound vibrations.

Third graders complete scientific investigation to determine what volume is and how it is determined by size not by mass. They discuss what they know about volume before proceeding with the demonstration and experimentation. After the...

Clay's as good a material as any to build a boat, right? An introductory instructional activity sets the stage for two activities associated with buoyancy. The first involves building boats out of clay, while the second uses these boats...

Students complete a unit of activities to learn about states of matter and how to measure matter. In this matter instructional activity, students complete 8 lessons to learn about matter, its states, and how to measure matter.

Students experiment in small groups to answer the question, "Is there a relationship between ramps and speed?" They apply a formula to calculate the speed of the cars used in the experiment, complete the associate lab report, and...

Fourth graders conduct a lab activity that measures the factors that change the swing rate of a pendulum. They create a hypothesis and test it during the experiment. They record their observations using the recording sheets and journal...

Pupils examine how the circumference, diameter, and the relationship of Pi of a circle are related. They count the summer rings of a tree to determine its growth.
