In this interactive demonstration students will make observations of diffusion of a semi permeable membrane and be able to compare these observations to the functions of a cell membrane.

The digestive system is investigated in this learning activity to help participants learn how food is broken down and prepared for absorption, and list the components of the digestive system as well as their functions. Organs investigated include the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus.

This lab activity is a paper fossil dig where students discover skeletal characteristics of humans, primates and hominids and are asked to make a short oral presentation to the class.

Spreadsheets Across the Curriculum module. Students analyze a given data set to understand the "Digital Divide" by means of percentages and the Subtotal tool in Excel.

In this short lab, students observe the movement of an air bubble in a small level, attached to a toy truck, as it is moved from a stop, to a steady speed and back to a stop. This gives a visual to the concepts positive acceleration, zero acceleration and negative acceleration.

Spreadsheets Across the Curriculum module. Students use spreadsheets to help find the difference in percentages of salaries between dirty and clean jobs.

This activity is a field investigation where students will observe three areas with high sensitivity to pollution, and test water quality in two of the locations.

This activity is a guided inquiry on the density of two liquids and salt. Students will then create their own experiment to back their findings.

In this unit, students make regular journal entries about a plant/animal/insect community in the natural area around our school and use this to create a Non-fiction Class Book. They also interview family/resources to discover, record and present stories about human relationships with nature from their culture(s).

This activity is an outside the classroom teaching with data experiment. It allows students to collect and analyze data in ordet to create a distance versus time graph and calculate average velocity from the graph.

This is an investigation where students observe what happens to land after it is mined. Students will create a hypothesis, observe their model, conclude what happens to land after it is mined, and discover the role humans play in land conservation.

Students will become familiar with the properties of magnets. They will design a data collection sheet to show where magnets are hidden in a closed box with their explanation of their findings. They will also design a game or activity using magnets and present their activity to the class.

This lab activity shows students the Law of Conservation of Matter and intermolecular forces by having them dissolve packing peanuts in acetone.

This activity is a field investigation where students find out what makes up soil.

This activity is a field investigation where students find out what makes up soil.

This is a field investigation on diversity of life where students count the number of kinds organisms in two locations. Students report their results on posters and propose reasons why there might be difference in diversity between the locations.

In this physics lab students will investigate whether Ohm's Law applies to common electric devices (incandescent light bulbs and LEDs). This activity is based on a PRISMS activity.

In this assignment, a group of four to five students will select one country that has been ranked in the World Development Indicators of the World Bank, the Human Development Indicators of the United Nations Development Program, and the Happy Planet Indicator of the New Economic Foundation. Using the selected country's political, social, and economic statistics, each group will assess the methodology and validity of the measurements of WDI, HDI, and HPI indicators for the country. Students will compare and contrast the measurement methods, analyze the strengths and weaknesses of each indicator, and propose recommendations to improve these indicators.

This activity is a guided inquiry where students will investigate if water molecules have any space between them.

An in-class demonstration of perception and individual perceptual differences, using optical illusions and visuals.
