Many of the genetic sequences found in the fruit fly genome are similar to those found in humans.

In this activity, learners can create five-layer density columns by employing one of three (or all) methods.

In this activity, learners explore how to stay fit the fun way. Learners participate in three physical activities.

This activity allows learners to explore the scientific method in an open-ended fashion, using the 4-P Approach to Science Inquiry developed by the University of Wisconsin, Beloit.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

This laboratory exercise is designed to show learners how DNA can easily be extracted from lima bean bacteria. This experiment requires the use of a centrifuge (not included in cost of materials).

In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.

In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.

In this lab activity, learners act as fellow scientists and colleagues of Isaac Newton. He has asked them to independently test his ideas on the nature of motion, in particular his 2nd Law.

In this activity, learners will design a way to identify a powder found at a crime scene by comparing it with known powders, with the goal of solving a crime.

In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.

Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.

In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.

In this activity, learners experiment and collect data during a simulation of the fluid shifts experienced by astronauts' bodies in microgravity.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.

This laboratory exercise is designed to show learners how DNA can be extracted from a chunk of thymus (sweetbread) or liver.

In this biology activity, learners use plastic pipettes to cut wells into the solid gel layer of agar in petri dishes and place solutions of simulated antigen and antibody preparations into the wells.

In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.

In this activity, learners add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules.
