Germs Experiment

Plants need food to survive, just like any other living organism. Young biologists analyze an experiment performed in 1610 by Jan van Helmont to determine if plant nutrition is obtained through the soil. First, lab groups work together...

Learn about George Washington Carver's important contributions to agriculture by studying the sweet potato. First graders read about the inventor's observations and prepare sweet potato slips for the class garden. Additionally, they...

Help young scientists connect with nature and learn about trees with a fun life science lesson. Heading out into the school yard, children choose a tree to adopt, taking measurements, writing descriptions, and drawing sketches of it in...

Students participate in an experiment to understand how germs grow. In this potato experiment students use their hands to touch a potato and leave it to see what grows on it. Students also observe a disinfected potato piece. Students the...

Second graders make a KWL chart and brainstorm what they need for the project of growing potatoes. They choose one potato and plant it in water or peat moss cups and choose a location in which meets the needs of the plants and make their...

Students use the scientific method to test an idea regarding the structures of a plant as it supports the biological evidence for life. For this growing roots lesson, students use organizing sheets to record their findings. Students...

Mr. Spangler's sons set out to prove that double-dipping (putting a potato chip back into a dip for a second blob on the chip), does indeed rapidly spread germs throughout the entire dip. After viewing this presentation, the next time...

Secondary learners explore food science by conducting an experiment using the scientific method and creating a science fair project based on their findings. They learn about food technology and modern research development. They...

Is there a way to avoid spreading germs to our friends and families? Come along with Jordan and Sydney as they research this topic.

Students design an investigation using yeast. In this environmental engineering lesson, students design an investigation to determine how environmental factors affect the growth of yeast. They will collect quantitative data and discuss...
