Free Science Curriculum

4th – 6th Grade:

This curriculum covers a variety of scientific fields and is designed to be hands-on, engaging, and interactive in order to help instill important scientific concepts.

 

Module 1: Introduction to Engineering

Learn about different types of engineers and discover the kinds of work they do.

Fields of Engineering – This is a list of popular fields of engineering. It includes descriptions of each and outlines what they do to help society.

Fields of Engineering Worksheet – helps kids sink it into their brains.

Siphon Experiment – Engineers are always trying to think of ways to solve problems using the items in their environment. This experiment was designed to illustrate that mindset, and to get kids to think in a similar way.

 Balloon Challenge – This experiment is relatively simple, but is great for teaching kids how to think like like engineers, and solve simple problems.

Engineer Spotlight

Take a closer look at civil, aerospace, and chemical engineers.

Aerospace Engineers – Learn about what aerospace engineers do, as well as some of the ideas and concepts that they have to understand in order to make things fly.

Civil Engineers – Discover what a civil engineer is involved in and explore some of the things that they have to think about when designing structures.

Chemical Engineers – Take a look at some of the areas a chemical engineer might work in, as well as the equipment they use.

 

Module 2: Physics

This section contains a brief overview of a few basic principles of physics. Learn about simple machines, forms of energy, and aerodynamics, all while conducting fun experiments!

Simple Machines

Simple Machines Worksheet – This worksheet provides definitions and real world examples of terms having to do with simple machines. It also includes a short questionnaire to help kids remember the terms.

Pulley Tug of War – This fun experiment demonstrates how pulleys can make work easier.

Super Bounce – This is a simple but really cool experiment amazes kids, and demonstrates momentum and conservation of energy.

Lifting with Levers: Levers are a super common simple machine used everyday for all kinds of things. This experiment illustrates how they work.

Inertia and Energy

This unit covers basic information about inertia and different forms of energy.

Tablecloth Pull – This experiment demonstrates inertia by whipping a tablecloth out from underneath a table setting. It’s quick, easy, and a lot of fun.

Inertia and Energy Worksheet – This worksheet covers information on inertia, different forms of energy, and laws of physics.

Surface Tension

This unit provides info and experiments on surface tension and why it works.

Water on a Penny – This simple experiment is a great way to illustrate how surface tension works, and how certain substances can affect the strength of water’s surface tension.

Surface Tension Worksheet – The worksheet provides definitions of terms related to surface tension.

Upside Down Water – This experiment shows how mysterious and fun surface tension can be with only a jar, some screen, and a bit of water.

Balloon Kebabs – Kids are wowed by this fun experiment that seems to accomplish the impossible.

Bountiful Bubbles – Who doesn’t like bubbles? Experiment with bubbles, and learn about how surface tension affects them.

Aerodynamics

This unit provides an overview of some of the basic principles in aerodynamics.

Bernoulli Balls – Learn about how air pressure can affect flight through this experiment that involves just a ping-pong ball and a blow dryer.

Aerodynamics Worksheet – Use this worksheet to learn terms related to aerodynamics.

An Airplanes Three Axes of Movement – Airplanes have three ways of turning: pitch, yaw, and roll. Discover how they turn the plane with this sheet.

Physics Review

View Physic Review PDF  All of the vocabulary words and concepts learned in this section are covered in this document. They are organized as multiple choice questions and can be used as a game-show type contest.  To play, make a set of three index cards labeled ‘A’, ‘B’, and ‘C” — you will need one set per contestant. Select two to four contestants to play the game. Give each child a set of the prepared cards. Read the question and multiple choice answers aloud. Ask the students pick their answer form A, B, or C card set and keep the answer secret. After all the contestants have made their selection, or their time is up, tell them to flip their cards. Who ever has the correct answer gets a point. Kids love this. Have a lot of fun with it, and possibly offer prizes for the winner.

Module 3: Chemistry

This section provides a general outline of chemistry and the basic principles involved. Conduct fun experiments while learning about things such as atoms and molecules, acids and bases, chemical reactions.

Atoms and Molecules

Atoms Molecules Worksheet

Marshmallow Molecules – Use marshmallows and toothpicks to create delicious molecules.

Moving Molecules – In this experiment, use food coloring and water to actually see the movement of molecules.

Acids and Bases

Discover acids and bases, and determine which household substances are acidic or basic.

Acids and Bases Worksheet – This worksheet provides definitions of acids, bases, and other related topics as well as multiple choice questions.

Cabbage Indicator – In this experiment, use red cabbage juice to test whether common substances are acids or bases.

Experiment Sheet – Use this handy sheet as a way to document your results. Write in the name of the substance you are testing, your hypothesis (Will it be an acid or a base?), and the result.

Atomic Structure

This unit provides info on how an atom is structured.

Atomic Cookies – This fun (and tasty) project will help students learn about the structure of atoms.

Atomic Structure Worksheet – Here is a worksheet that explains how the atom is structured.

States of Matter

In this unit, learn about the solid, gas, and liquid stages of matter.

States of Matter Worksheet – Use this worksheet to learn terms relating to states of matter. Then, test your knowledge by answering questions.
