Making models is always memorable. In this activity, physical science starters examine the structure of hydrocarbons using marshmallows, raisins, and toothpicks. They even act as atoms themselves and link arms to represent covalent...

Students examine distribution of water and minerals. In this surface and groundwater lesson, students conduct an experiment with fresh and salt water making hypothesis and drawing conclusions about minerals. 

Fourth graders, using candy, build models of DNA replication, RNA transcription, and tRNA translation.

Students explore the water cycle. They learn the "Water Cycle Boogie." Students create hats to represent the different parts of the cycle and learn hand motions to go with the words of the song. Students practice singing the song and the...

Students construct a 3-D model of DNA. They demonstrate an awareness of base pairs in written work and in a model. Students model DNA replication using edible materials. They record concluding thoughts in their science notebooks.

Learners explore the concept of molecular modeling and differentiate between saturated and unsaturated compounds. In small groups, they identify molecular formulas, complete a chart comparing alkanes, alkenes, and alkynes, and construct...

Students comprehend the four parameters of water quality. They perform tests for salinity, dissolved oxygen, pH and clarity or turbidity. Students comprehend why scientists and environmental managers monitor water uality and aquatic...
