Curated OER
Mixtures
Sixth graders experiment with mixtures. In this chemistry activity, 6th graders determine which mixtures are considered heterogeneous, a suspension, a solution or a colloid. Students create a data sheet of what they discover.
Curated OER
Celebrate The Four Seasons
Students investigate cause and effect and compare and contrast how recurring cycles are evident in multiple aspects of their education. They answer questions in the chosen field. Students model each aspect by interpreting, perceiving and...
Curated OER
Scientist Simulation
Students imagine themselves working as research scientists completing the end-steps of a molecular research project and interpreting the data. They compare the gene sequences of normal and abnormal mice and evaluate the protein product...
Curated OER
Measuring Aquatic pH
Students apply the scientific method and safety rules to aquatic pH. They test unknown solutions for pH levels.
Curated OER
I Need Room to Breathe
Seventh graders explore how exercise affects carbon dioxide levels in exhaled air.
Curated OER
SEPARATION OF A STARCH-GLUCOSE MIXTURE USING GEL FILTRATION
Students make a starch-glucose solution and pour it through gel in order to separate the starch from the glucose. They examine how starch is a larger molecule than glucose and test for the presence of these substances using other...
Curated OER
Separating a Starch-Glucose Mixture Using Gel Filtration
Young scholars experiment using the basic principles of gel filtration. They use the gel filtration technique for testing for the presence of specific substances. Students discover that starch is a larger molecule than glucose.
Curated OER
Vegetables
Third graders evaluate what happens when vegetables are cooking in different solutions. They observe the effect of color change on cooking vegetables.
Curated OER
It's a Crash Test, Dummy
Students use the internet to research air bags in cars and trucks. In groups, they discover air bags history and the safety issues surrounding them. They create their own design of a new air bag and test it using a raw egg in...
Curated OER
The Penny Factory
Fourth graders identify the characteristics of a simple physical and chemical change. They describe objects by the properties of the materials from which they are made and separate or sort items using these properties. Students explain...
