2018 Lesson #4 Light, prisms, rainbow science & kaleidoscopes

Image result for how are rainbows formed

In this lesson we will be learning about PS3 A- Definitions of Energy, PS3 C- Relationship between energy and forces

In class we will be learning of refractions and light and how it is a form of energy. We will be experimenting with prisms, light and rainbows.

Light is made of tiny photons which contain lots of energy. … Light is also called electromagnetic radiation when speaking of light other than visible light. Of all the forms of radiation and light on the electromagnetic spectrum, humans can only visibly see a very small amount of light.

A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multi-colored circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.

2018 Lesson #3 Chemical reactions, oobleck & sink or float activities

Image result for oobleck

This lesson we will be learning about PS2 B Types of interactions, PS2 C Stability and instability in physical systems, PS1 B Chemical reactions.

In class we will be testing different items to see if they sink of float. We will be making oobleck (a non-newtonian fluid) and also experimenting with chemical reactions.

What is a chemical reaction? Think about baking a cake. Each ingredient has a job to do. Flour provides the structure; baking powder and baking soda give the cake its airiness; eggs bind the ingredients; butter and oil tenderize; sugar sweetens; and milk or water provides moisture.

Combining the dry and wet ingredients puts them to work — the proteins in the flour bond and create gluten, giving the cake its flexibility. Eggs hold the mixture together. Baking powder and baking soda each release carbon dioxide, adding bubbles to the batter, helping it expand (Chemical reaction). Baking is a science!

Physical changes result from a changing in the physical state of a substance. The physical change can be melting, evaporation, or boiling. For instance, ice melts into liquid water, and the liquid water can be turned into steam through boiling. The arrangement of the molecules making up the ice and water change into different states, but the molecules still remain water molecules during each change.

chemical change occurs as the result of a chemical reaction. During a chemical reaction, the atoms within a substance are rearranged into different combinations. For example, sugar undergoes a chemical change when it is cooked to make caramel. The heat from the cooking converts sugar molecules into different molecules that give caramel its color and flavor.

Several general types of chemical reactions can occur based on what happens when going from reactants to products. The more common types of chemical reactions are as follows:

  • Combination

  • Decomposition

  • Displacement

  • Combustion

  • Redox

2018 Lesson #2 Chemistry, measuring & density

chemistry-740453_1920

This lesson we will be learning about PS1A- Structure and properties of matter, PS!B- Chemical reactions. I want to familiarize students with different ways of measuring things in a lab.

We will use the triple beam balance and weights, different scales and volumes and learn different ways of how to measure things.  

We will learn about density and what makes some liquids more dense than others and test out our theories.

Density is a word we use to describe how much space an object or substance takes up (its volume) in relation to the amount of matter in that object or substance (its mass). Another way to put it is that density is the amount of mass per unit of volume. If an object is heavy and compact, it has a high density.”

Volume refers to the amount of space the object takes up. In other words, volume is a measure of the size of an object, just like height and width are ways to describe size. If the object is hollow (in other words, empty), volume is the amount of water it can hold.”

We will also build molecules with molecule kits

A molecule is the smallest unit of a substance that has all the properties of that substance. For instance, a water molecule is the smallest unit that is still water. A water molecule can be divided into tiny parts called atoms. This produces two hydrogen atoms and one oxygen atom.”

2018 Lesson #1 Vortex cannon & waves

4 domains of science

I am changing up how I am teaching science this year. I will be teaching the four domains of science according to the NGSS which are: Physical Science, Life Science, Earth & Space Science,  & Engineering/ Tech/ Applications of Science. We will be learning about all of these and how to use the cross- cutting concepts while doing experiments.

This lesson we will be learning about PS4 A: Waves and their applications in science and PS2: Motion and stability

In lab we will be making our own vortex cannons and learning what makes the air move, describing the characteristics of air and all of the different waves. We will look for patterns and also the structure and function of the vortex cannon.

An air vortex cannon works primarily by applying force quickly and efficiently to air molecules contained in a semi-enclosed space. When the stretchy balloon surface at the back of the cannon snaps forward, it collides directly with air molecules, accelerating them towards the opening of the cannon and setting off a chain reaction of high-speed collisions with other air molecules and the sides of the cannon’s barrel. The only way for all of these colliding high-speed air molecules to escape is out through the opening at the end of the barrel. The rapid escape of the air molecules forms a stream, or jet, of air that flows straight out of the cannon. Poof!

It’s going to be awesome! It’s about to get crazy in here. We are “blasting” into a new year full of science experiments- wahoo!!!

Lego your mind and explore (Unit #12 Thomas Edison)

Thomas Edison

“I have not failed. I’ve just found 10,000 ways that won’t work.”~ Thomas Edison

Thomas Alva Edison (February 11, 1847 to October 18, 1931) was an American inventor who is considered one of America’s leading businessmen. Edison rose from humble beginnings to work as an inventor of major technology, including the first commercially viable incandescent light bulb. He is credited today for helping to build America’s economy during the nation’s vulnerable early years.

Inventor Thomas Edison created such great innovations as the practical incandescent electric light bulb and the phonograph. A savvy businessman, he held more than 1,000 patents for his inventions.

“Edison’s inventions and improvements on already invented equipment let people live more comfortably. His inventions provided entertainment. The telegraph let people send messages quickly. In war time or emergencies, telegraphs saved lives. When the Titanic sunk in the Atlantic Ocean, a telegraph alerted rescuers to the disaster. ~ Easy science for kids

The Lorax (Unit #11 Rachel Carson)

Rachel Carson2“Science is part of the reality of living; it is the what, the how, and the why of everything in our experience.” ~Rachel Carson

“One way to open your eyes is to ask yourself, What if I had never seen this before? What if I knew I would never see it again? ~ Rachel Carson

Rachel Louise Carson was an American marine biologist, author, and conservationist whose book Silent Spring and other writings are credited with advancing the global environmental movement. She first alerted the world about the environmental impact of fertilizers and pesticides.

A marine biologist and nature writer, Rachel Carson catalyzed the global environmental movement with her 1962 book Silent Spring. Outlining the dangers of chemical pesticides, the book led to a nationwide ban on DDT and other pesticides and sparked the movement that ultimately led to the creation of the U.S. Environmental Protection Agency (EPA). ~ womenshistory.org

Science in the community (Unit #11 John Muir & Rachel Carson: Botany / Environmental Science)

recycle binsplant a tree

BONUS: Go recycle bottles, paper and other items and drop it off at CMS recycling drop offs OR plant a tree

In class we will be learning all about ecosystems, food webs, pollution, and talking about humans affect on the Earth and what we can do to improve it. We will be learning about the Brianhead fire and its aftermath. The students will participate in an oil spill challenge and some Lorax activities and games.

I love learning about how to help save the planet. It can be in small ways that can make a big impact- like turning off the lights at home, not wasting water and turning it off while we brush our teeth and not watering our lawns when it is super hot outside, recycling, etc. I hope the students know they they can make a difference.
