For this science worksheet, students find the terms that are related to the concept of the ocean salt and sand. The answers are found by clicking the link at the bottom of the page.
Curated OER
Extraction of DNA from White Onion
Students investigate techniques involved in extracting and isolating DNA. Students extract and observe onion DNA.
Curated OER
How Does Water Cool?
How fast does water cool? First fifth graders will draw a line on a graph that predicts how fast they think water can cool from boiling. Then they plot the actual data on the same graph to see if their estimate was correct.
Curated OER
Ions in the Environment
Students explain the importance of the five main biogeochemical cycles. In this chemistry lesson, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.
Curated OER
A Solution for Moles
Students calculate the concentration of different solutions. In this chemistry lesson, students explain what a solution is. They explain ways to change the concentration of a solution.
