Curated OER
Apologia Gen Sci 3 Word Search Puzzle
In this science worksheet, students look for the words that are related to the theme of the worksheet. They also work on the skills of spelling and word recognition.
Curated OER
The Lepidoptera Project
Students are introduced to Scientific Inquiry and discover how to design an experiment that answers critical questions using butterflies as the topic. They design experiments that compare the number of species of butterflies in a vacant,...
Curated OER
Living in Extreme Environments
Students explore the living conditions needed to grow bacteria. They develop an experiment that will test the ability of bacteria to survive various temperature extremes. In addition, they complete a lab reprt to share their results.
Curated OER
A Human-Powered Vehicle for Trans-Glacial Transport
Students practice problem solving skills and experimental design. They build a vehicle that can traverse "glacial" ice capable of carrying a specific load and glide smoothly, creating as little effort as possible for the skier pulling...
Curated OER
Who Needs What?
Learners identify the physical needs of animals and if plants need the same things as animals. They conduct an experiment to see if plants need light and water to grow. They compare the growth of the plants exposed to the different...
Curated OER
Organs to Go...
Students explain the principles of experimental design and reinforce the steps of the scientific method. Each group of students create a "slush" type mixture to store a chicken liver.

Teach Engineering: Does Your Chewing Gum Lose Its Flavor?
In the first part of the activity, each student chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days before weighing it to determine the amount of mass lost. This mass corresponds to the amount...

Teach Engineering: Who Needs What?
The teacher leads a discussion in which young scholars identify the physical needs of animals, and then speculate on the needs of plants. With guidance from the teacher, the students then help design an experiment that can take place in...
