A fun (and delicious!) lesson teaches measurement to your third graders. They work in small groups to first predict, then to measure the weight, circumference, and number of seeds found in a watermelon. Everyone gets to eat watermelon...

Second graders examine The Learning Page Fact Files about ocean life and categorize the data by weight and group. They distinguish between fish, mammals, and invertebrates and which weigh the most and the least. Students record their...

Sixth graders discover their weight relative to the other children in their class. They determine how many calories they burn through exercise and compare it with their classmates. Using the internet, they calculate their body mass index...

In this math worksheet, students compute the range, mean, median and modal weight of candy bars from two machines. Students write a short essay about which machine is using too much chocolate and which is more reliable.

Weight, time, length, cost, and mass are all things we can measure. Learners are introduced to the concepts they'll need to know before embarking on any measurement adventure. They are introduced to each type of measurement and types of...

Love this activity! Learners fill cans with slips of paper to identify positive and negative feelings. They connect negative feelings to weight, and discuss how negativity can get you down. What a wonderfully visual way for learners to...

Students study about perimeter and the units used to measure perimeter using a variety of materials including their hands, feet, rulers, and computer applets. They understand such attributes as length, area, weight, volume, and size of...

First-time physicists experiment with pendulums in this physics lesson. They vary the weight of the bob, record how long each takes to complete ten period swings, and then calculate the time for one period. They repeat the procedure,...

Fourth graders study straight line motion and the forces that affect motion, including the terms force, gravity, and speed. They determine that gravity, weight, and other forces have an effect on speed and motion.

The rides at a theme park always have limits on weight or number of riders. This makes a natural example of the use of inequalities to solve real-world problems. Learners explore intuitive solutions using substitution to solve the...

Here is a math lab that helps young mathematicians understand the real-life meaning for vector addition. By building a model using spring scales and washers as weight, and then calculating the vector addition using two different methods,...

Sixth graders set up a pendulum experiment deciding which variable to manipulate (length of string or weight on the string). They create a hypothesis, collect necessary equipment, and write out each step of their experiment. They then...

Fourth graders discover that distance and obstructions can affect the strength of magnetism. Students work in pairs and follow instructions given to investigate how weight and distance affects the magnetism on certain objects. Students...

Fourth graders explore the earth's gravitational force. They discuss objects in motion and the concepts of pulls and pushes. Students investigate the idea that falling and gravity can be useful in connection with various sports...

Mountain bike riding, zipping up and down dirt trails, flying through the air, the smell of trees all around, the sound of birds chirping, this is idyllic! Yet it is also a lot of hard work. Balance is the key, whether going uphill,...

Students analyze rocks. In this geology lesson, students collect rocks from the schoolyard and sort them according to various characteristics, such as color, size, and weight.

Use this comical slide show with your youngsters to review verb tense and tense shift. A shirtless weight-lifter guides your class through examples on how to correct common errors. There are 22 slides included, and several questions to...

Quiz the class on which unit of measure would be most appropriate when determining the weight, volume, height, or distance of eight different objects. This quiz reviews liters, kilometers, milligrams, and centimeters. 

Hands-on is the best way to play. Learners read a graph that shows the force needed to stretch a rubber band. They do this and then participate in a simple experiment where they create coiled springs with wire. They work to determine how...

Make letter sounds a game for pre-readers using these letter cards. After you demonstrate, learners take turns drawing letters out of a bag. Weight them for the letters they have been practicing most recently. Once they've chosen a...

Learners study product packaging and determine if it is excessive and if it is recyclable.  In this packaging lesson students examine and identify waste reduction techniques. 

Pupils confirm the law of conservation of matter by weighing chewing gum before and after it is chewed.

Students stack several different colored marshmallows-one on top of the other-in the tall cylindrical container. They ct a cardboard disk to fit snugly inside of the container on top of the marshmallow stack using a compass if necessary....

In this fractions activity, students solve 10 short answer problems. Students find items around their home and weigh them. Students convert units from one unit to another in the customary system.
