Teacher worksheets for your science classes of all grade levels. Whether you are teaching biology, hydrology, botany, or chemistry, or just studying the lives and work of famous scientists in general, each of the following sets of science worksheets contains multiple individual reading passages for your students. Two separate answer sheets are associated with each passage. One is a multiple choice worksheet and the other is a short-answer worksheet. Instructors may choose to use either or both question sheets (answer keys are provided for all worksheets). You will find a nice helping of reading in the content area sheets here too.

The worksheets span a wide array of science topics. The interesting thing is that we always find a way to cover elementary, middle school, and high school science topics and leveled work.

Acids and Bases

A great look at the middle and high school level of this Acids and Bases.

Animal Anatomy

A look at the function of many different parts in different members of the animal kingdom.

Astronomy

These worksheets explore outer space and the things spinning around it.

Atoms

The fundamental unit of all matter is explored in depth.

Bacteria and Viruses

The super small living things that are almost equally as helpful to humans as they are harmful.

Cells

Discover the basic units of life.

Chemical Reactions

When compounds or mixtures come in contact with one another electron transfer can make a ton of different cool things happen.

Chemistry

We look at the study of matter.

Classification

Giving things proper names insures that we are all studying the same exact thing.

Collecting Data

Data collection is one of the fundamental processes of science. We work on getting it right the first time.

Dinosaurs

These magnificent creatures of the past provide a huge wonder in all of us.

Earth Science

One the four main branch sciences. We need to spend some time on understand the planet we inhabit.

Earth's Tilt and Seasons

Because the Earth axis is tile it has hug consequences for all parts of the planet.

Ecology

We look at how living things interact and share an area.

Electricity

The movement of current along a circuit is complex and can be used to our advantage.

Endangered Animals

We look at animals that are rare in nature and often forced to be in captivity to allow the species to continue on.

Force and Motion

Newton's pesky laws come into play for the first time here.

Forensic Science

A science that was created with a person helps us understand how things went down.

Forms of Reproduction

A look at how different organisms make copies of themselves to keep their species going.

Fossils

A look at layers of the past and what dead organisms and substances can tell us about that past.

Flying Animals

These aren't your everyday birds, in fact, there aren't many birds in here at all. You would be amazed by some of the animals that can take flight.

Genetics

We look at how traits are passed on to offspring.

Oceans

We looked at what lives in the ocean. Now we take a look the dynamics and physics behind oceans. For instance, "Where do waves come from?"

Periodic Table

A breakthrough that shows how elements have likenesses and differences.

Precipitation

This section tries to answer some common questions that many have about the return of water to planet Earth. These are things that we often take for granted like rainbows.
