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.

Mass and density are difficult topics for kids to understand, and even more difficult when you have visual impairments or blindness. Learners will make boxes and fill them with cotton, sand, or crushed paper. They will feel the density...

Learners compare the weight of the students's favorite soft toys directly and then indirectly using beads.

Facilitate learning by using small objects to teach the principles of atomic mass in your science class. Pupils determine the average mass of varying beans as they perform a series of competitive experiments. They gather data and...

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.

Beginning biologists explore passive transport through two demonstrations and a hands-on inquiry. Spray air freshener from one spot in the classroom and have class members raise their hands as the scent reaches them. Also, place a teabag...

Definitions of gravity and weight and the calculations involved with their manipulation are covered here. The equations and resource links will be valuable to show a physics class. Use it as a note-taking support for your lecture on...

In this measurement activity, students identify the units of measurement, the instrument used to measure and the method used to measure weight, mass, density, volume and length. They also answer questions about measurements and find the...

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

Learners estimate and determine the number of cents (pennies) that are needed to equal the mass of a variety of common objects. They develop a process for measuring and explore concepts related to units of measurement.

Challenge your second graders with a worksheet on units of measurement! Not only do they put their measurement skills to the test, but kids practice word problem strategies as well. The second part of the resource prompts students to...

Young scholars 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.

As your scholars become comfortable with liquid mass and volume units, give them these addition and subtraction word problems to help apply the skill. There are no conversion or fraction skills involved. After solving four word problems,...

Start the day with four simple mass problems. These problems have learners determining who weighs more, comparing masses, and computing an amount given a base weight. This presentation would also work nicely at as extra credit.

Conversion immersion — it's measuring mania! A set of four activities teaches scholars to convert between customary and metric units. Resource covers unit conversions in length, temperature, weight/mass, and volume.

Studies show that obesity is now a global problem. But how are researchers measuring obesity? Young scientists investigate the myriad of methods for measuring body fat through a presentation. From hands-on to high-tech, viewers learn...

Obesity is a worldwide concern. Using survey results, learners compare local BMI statistics to celebrity BMI statistics. Scholars create box plots of the data, make observations about the shape and spread of the data, and examine the...

Build a basic understanding of units of measure and create a great foundation for your learners. The lesson gives a complete overview of everything measurement, from types of measurement to rounding to conversions — it has it all! 

Energy is just energy, right? Explain various forms of energy to your young scientists by using an interactive experiment that contains common objects to demonstrate complex concepts. Pupils conduct experiments for radiant, thermal,...

In this measurement worksheet, students determine how gravity affects your weight and mass on a different planet. Students practice converting measurements to different units. This worksheet has 12 problems to solve.

In this gravity worksheet, students will compare the difference between mass and weight and the unit of measurement used for weight and mass. Then students will compare the weight of objects on the Earth and on other planets. This...

Elementary-aged scientists discover that all matter has mass. They are shown the difference between mass and weight, and learn how to calculate mass using the appropriate tools and methods. The scientific method is used while estimating...

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...

Assist your class with correctly calculating the values for force, work, and power as they determine the amount various activities require. They gather data and participate in a group discussion to compare results upon conclusion of the...
