Make your lesson on radioactive decay pop with this lab exercise. Using popcorn kernels spread over a tabletop, participants pick up all of those that point toward the back of the room, that is, those that represent decayed atoms. As the...

In this half-life worksheet, students use 100 pennies to simulate radioactive isotopes and half-life. They place the pennies in a box and shake the box. All pennies that turn up tails are removed from the box. They represent the isotopes...

Young scientists use a worksheet to help them perform a lab on the decay of a radioactive element. The worksheet serves as both a task guide and a lab sheet for pairs of learners. This activity requires a calculator and has excellent...

A series of math and science activities feature M&M's® as manipulatives to help kids work through equations. The resource includes exercises on finding averages, percent of compositions, moles in chemical reactions, genotypes and...

In this detailed and comprehensive multi-day activity, budding evolutionary biologists use real data from lizard populations in the Canary Islands to examine evolution and natural selection. 

In this radiation worksheet, students use a data table to determine what kind of radiation is being emitted by unknown sources. This worksheet has 3 problems to solve.

In this radiation worksheet, students compare the effects of shielding on radiation on known isotopes. This worksheet has 2 problems to solve.

In this DNA fingerprinting simulation worksheet, students perform an activity that represents using a gel electrophoresis. Students decide who commits a crime in a forensics style lab.

For this irradiation worksheet, students simulate the effects of irradiation on bacteria growth by using UV light. Then students complete 6 short answer questions.

In this chemistry review worksheet, students answer and solve 95 questions about chemical reactions, hydrocarbons, functional groups, moles, acids and bases and solutions.
