Students investigate major pigments which occur naturally in fruits and vegetables, and to use them to dye a number of items. They study the effects of pH on anthocyanin on pigments.
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
Why do we need Vitamin C in our diet? Or Why do we carry old inactive genes in our genome?
Students explore and explain how mutations in the DNA sequence of a gene may be silent or result in phenotypic change in an organism and in its offspring. They analyze how evolution and biodiversity are the result of genetic changes that...
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...
