Students study the concepts of weight and drag while making paper helicopters. They measure how adding more weight to the helicopter changes the time for the helicopter to fall to the ground. They apply what they examine to the work of...

Students design a structure capabl;e of holding a textbook. They demonstrate that the weight of a textbook is offset by the normal force exerted on the book by the structure.

Students measure the length, width and height of different materials.  In this design instructional activity students complete a lab to see what engineers need to consider when planning a structure.

In this moles activity, students read about mole and learn how to calculate the number of moles in specific mass of compounds. This activity has 14 problems to solve.

Young scholars determine the mass of various objects. In this integrated math and science lesson, students use an arm balance to compare a known object to a combination of washers with a fixed weight. Young scholars record data,...

Using a table, students solve 12 word problems about the weights of various foods at the grocery store. The solve addition and subtraction problems as well as convert kilograms to grams.

Some consider physics the branch of science concerned with using long and complicated formulas to describe how a ball rolls. This presentation, while long, is not complicated, yet it covers rolling, falling, and more. It compares vectors...

Students estimate the measurement in centimeters for common classroom objects. They check their estimations, discuss the differences and write a paragraph summarizing the activity.

Learners explore atomic measurement in the first activity in a series of 36. Through readings, activities, and questions, classes review standard SI units, learn about Avogadro's constant, and use it to help them calculate moles. They...

The Law of Conservation of Matter can be complex for young scientists to fully grasp. Use this experiment to help simplify the process as pupils perform two experiments to determine mass: one that melts a substance and the other that...

Stop and drop what is in your hand! Pupils investigate how form effects drag in the 12th part of a 22-part unit on aviation. Groups create equally weighted objects and determine which one falls the fastest by collecting data.

Get into the swing of things. Pupils use a pendulum to demonstrate the conversion of potential energy to kinetic energy and back. After measuring the speed of a pendulum and compare it to the calculated theoretical speed, they...

Model and explore osmosis using squash and potatoes. Young scientists expose chunks of potatoes to different concentrations of a squash solution. They compare the weights of the chunks before and after exposure to the solution and use...

Students construct the Metric Pyramid from the handout. They use the Metric Pyramid to convert from standard to metric measure and vice versa. They compute their own Body Mass Index.

In this body fat measurement worksheet, students will conduct an experiment to determine how the "under-water weighing" technique of measuring body fat works. Once the experiment is complete, students will complete 1 short answer question.

Students explore the measurements of capacity by constructing a creative project in the shape of a man. The man has body parts that represent different units of measurement and can be used to make conversions. This is highly concrete and...

Learners explore characteristics of mass. In this scientific inquiry about mass lesson, students drop rocks of different weights from various heights and record the depth of the "crater" created.  Learners record their findings on a...

Young scholars review estimation, measurement, fractions, decimals while familiarizing themselves with a new classroom at the beginning of the year.

Students make generalizations about weight and mass by engaging in two hands-on experiments. In this weight and mass lesson, students weigh both an empty beaker and beakers with various amounts of weight inside of them in order to find...

Young scholars calculate their BMI and compare it to a healthy weight chart.  In this health lesson, students compare the perception of overweight with healthy weight charts. Young scholars interpret collected data and evaluate...

Students investigate where a new element would be located on the periodic table. In this isotope instructional activity, students find the mass of a new element, people mass. This number will be entered onto the periodic table of...

For this conversions worksheet, students complete 8 problems where they convert amounts of weight and mass including pounds, tons, ounces, milligrams, and more.

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. 

Third graders explore and identify the tools that can be used to measure length, mass/weight, and volume. They discuss how things are measured using different units, and observe the difference between the English and the Metric systems....
