Science 18/19


4/23  Bridges, bridges and more bridges. 

4/30 Testing Week

5/7 One more day of bridges

5/14  Testing the Bridges

For previous weeks', go to Mary's Science Page

4/16  Bridges, bridges and more bridges. We compared difference between beam, arch and truss bridges. Then started building our own.

4/9  We started our study of bridges.  Learned some basic vocabulary. Experimented with load differences as the span of the supports change.

3/26 We finished our calculations and made the pan flutes.  We also made music with flasks of water!

3/19 We expanded our experience of the visiting musician and symphony visit by learning about the different types of instruments and how they produce sound.  We are using ratios of the octave notes to make our own flutes.

3/12 We had a great time at the symphony. Thank you to Naio and Lily for coming to the science fair to present our class project!

3/5/19  We came to our conclusions and worked on our lab reports & display. Come to the science fair to see what we discovered!

2/26/19  Experiment Day was fun!  Next week, we will write our conclusions and design our class project board.

2/19/19  Students decided on the question they want to try to answer, wrote their hypothesis and designed their experiment.  Next week is Experiment Day!

2/5/19  We started our discovery of motion by making rollers and racing them across the classroom.

1/29  We played Minefield and talked about behaviors that follow and don't follow our 3 agreements: Be Safe, Be Kind & Be Responsible.  We also practiced random acts of kindness

1/8 & 15 Minerals vs Rocks - took a look at the building blocks of rocks...minerals.  Given six unknown minerals, students completed different tasks collecting data to determine the name of each mineral.

12/18 Review the 3 types of rocks by doing a matching activity and playing BINGO

12/11 Metamorphic Rocks

12/4  Sedimentary Rocks

11/27 We watched a video about volcanoes and learned about the Ring of Fire, types of volcanoes, and some of the igneous rocks that are formed.  Students looked at different igneous rocks and used information to identify the names of each.  We then worked more on the volcanoes.

11/13  We started to look at the Rock Cycle and the differences between the different types of rocks. We finished making the volcanoes.

11/6  This week we learned about properties of rocks and started building our volcanoes. Next week, we will start with minerals, the building blocks of rocks.

10/30 We made slime!

10/23 This week we learned that many of the items that we use in our daily lives are made of earth materials.  We discussed that the process of mining materials can be detrimental. Students then modeled mining practices trying to make a profit like a business person but also trying to preserve the earth like an environmentalist.

10/16  This week, we learned about the Loma Prieta Earthquake that rocked Santa Cruz on October 17, 1989.  We looked at videos of the event and modeled different types of plate movement that can occur.  Who knew that molten rock could taste so good? Next week, we will attempt to build structures that can hold up to earthquakes.

10/9  This week, students traveled through a series of stations asking questions relating to geology and what geologists do.  Next week, we will learn about a memorable day in Santa Cruz.


4/24  Physics of Rollercoaster - we continued working on their roller coasters.

5/1 Testing week

4/17  Physics of Rollercoasters - we briefly learned at rollercoasters are safer than they seem.  Wooden and steel roller coasters have different characteristics creating a different kind of ride.  Groups started making a paper coaster.

4/10  We started with a demo making silver and copper precipitate.  We completed a mystery lab by using chemical reaction results to determine each of the chemical reactants. 

3/27 - We continued our discovery of understanding the difference between chemical and physical change.  The Ziplock bag Lab showed us signs of several chemical reactions occurring.  Students then designed their own experiment to determine what they were!

3/20 - We continued our discovery of understanding the difference between chemical and physical properties and change.  We did "What a Gas" Lab to observe the Law of Conservation of Matter.

3/13 - We continued our discovery of understanding the difference between chemical and physical properties and change.  We completed the Paper Lab, took a closer look at the chemical equation represented in the lab, learned about the Law of Conservation of Matter, and balanced some chemical equations!

3/6 - We continued our discovery of understanding the difference between chemical and physical properties and change.  We finished the marshmallow lab. Yum!

2/27 - We finalized the What's a Solution? Lab and found that water is the better solvent.  After a short intro video about Physical & Chemical Properties/Changes, we started the Marshmallow Lab to help us explore these concepts. 

2/20 - We learned about different types of mixtures: heterogenous, solutions & colloids.  What's a Solution? Lab gave students more experience in determining what makes a solution and what doesn't.  We will also determine which is the better solvent: water, alcohol, or oil.

Compounds & Chemical Bonding

1/16  - 2/13  We learned what makes a compound and it's characteristics. Then, we made models from colorful marshmallows.  Ionic and covalent bonds are part of the make-up of compounds.  We completed the Acid/Base Lab using an indicator and more specific pH paper.

1/9  We reviewed the atom structure of the first eighteen elements and looked at the patterns that exist.  We started to look at compounds and hinting about chemical bonding.

12/19  Flame Test 2 looking at spectrometry

12/12  We learned about the patterns of the periodic table and the information that can be determined by knowing the patterns.  We learned about the colors that certain metals emit when heated and cooled.

12/7 worked with positive and negative numbers as they relate to protons and electrons.  Played Race to the End.  Learned about sublimation and properties of dry ice.

11/28 We started with some chemistry puns. Then, reviewed how to use the information from the periodic table to calculate the number of protons, neutrons, and electrons and finished drawing models of the first 18 elements.

11/14 We learned about the structure of the atom and made model candy atoms.  There are 2 homework assignments due by the next class on November 28.  

11/7 We started to learn about the atom structure using POGIL.  Our lab was the Black Box Theory.

10/31 We made slime!

10/24  This week we continued learning about the history of the atom model theory and preparing the slide for sharing information to the class.  Continuing our mission to look deeper into HOW and WHY things work, we explored with a favorite substance, Oobleck, to try to explain what happens at the molecular level when it acts as a liquid vs when it acts like a solid.  Next week, we will look at the answers and students will present the information they gathered about the atom model.

10/17  This week, we started our exploration of the periodic table and the information it contains.  Students were given a name of a scientist to research.  Then, they need to create a slide with pertinent information regarding the theory of the atom model that the scientist discovered.  Next week, we will look at the full History of the Atom Model Theory.

HW:  Finish the slide about the scientist you are researching.  

10/10  This week we looked at the WHY of states of matter.  Next week, we will look at the History of the Atom.

HW:  States of Matter
