Students explore the concept of weight and mass and the importance of units. Using a balance, they determine the weight of various objects in the unit of "pebbles" and in grams.

Students view a video and complete experiments with force and motion.  In this force and motion instructional activity, students examine small pieces and how they affect the motion of a toy car.  Students also experiment with...

Young scholars experiment to observe air and its mass.  In this air lesson, students use the scientific method to complete experiments that demonstrate the properties of air. Young scholars view a video as follow-up.

Students perform experiments to see if items will sink or float. In this sink or float lesson, students work in groups to make predictions, and record the results. After the experiments are complete students make a book of the results.

Learners are introduced to how the different types of rocks formed. As a class, they are read a book about rocks and create a list of what they already know about them. Using examples of rocks they find around the school, they discover...

Students identify what mass is and how to measure an object with a balance in gram units. Students identify weight and how to measure with a spring scale in units of force. Students compare the masses of two objects by placing each on...

Learners listen to story, "The 100-Pound Problem," compare their weight with character in story, and weigh different classroom items using nonstandard units and standard units. They experiment with different items that can make scale...

Students explore physics. In this science instructional activity, students discuss physics in their everyday lives. Students complete a physics worksheet.

Students estimate how many children in their class it would take to equal the mass of one adult bear. They then weigh and record their measurement on a chart to check their estimate.
