Mrs. Savage's AP Physics 2 class using probes to determine the resistivity of Play-Doh. This means they are determining how much a material opposes the flow of electric current through it. #RHSScience @RHSRaiders

Spent this morning with @RHSRaiders #GreenTeam participating in @cityofdentontx #StreamClean It was a great time working with some incredible students making a difference in their community. @dentonisd #DentonISDDelivers

Ms. McDaniel and her Green Team combined forces with the Architecture Club to make repurposed bird houses and feeders for our new RHS Rain Garden area. #Upcycle #Recycle #RHSScience @RHSRaiders @dentonisd

Strawberry DNA Extraction Lab Breaking down the organ, tissue, cell and nuclear membranes to access the molecule before getting it to precipitate out of solution into cold isopropyl alcohol. 🍓 🧬 #RHSScience @RHSRaiders @dentonisd

With the start of our focus on DNA, we transformed ourselves into the individual nucleotides that combine to form the polymer structure. Base pairs, hydrogen bonds, covalent bonds and antiparallel strands all represented. #RHSScience #DNA🧬 @RHSRaiders @dentonisd

Mrs. Woodard’s #Chemistry classes enjoyed the nice weather this last week and took their lesson over Bohr models of atomic structure outside. #RHSScience #BohrModel @RHSRaiders @dentonisd

Focusing on cell membrane structure and transport this week. Getting in some hands on science with a three day #osmosis lab with “naked eggs” in various solutions. 🥚 #RHSScience @RHSRaiders @dentonisd

Finding change in mass and egg circumference after soaking in a hypertonic corn syrup solution for 24-48 hours. Now to explain why and how the change happened before switching the egg to a new solution of distilled water and another 48 hour soak. To be continued… 🥚

We have been living in the land of #Photosynthesis this week reinforcing the process in a variety of ways with diagrams, pictures, demonstrations and even song. 🎵 The second half of my Cellular Energy Song will debut next week. #RHSScience @RHSRaiders @dentonisd

Putting it all together…Understanding the cycle between the two processes and the energy conversions that take place. Hear it, write it, say it, sing it, draw it…understand it! ☀️💧💨🌳🌾🍞⚡️ #Photosynthesis #CellularRespiration #RHSScience @RHSRaiders @dentonisd

Simple demonstration in class showing oxygen as a product of photosynthesis. Pictures are from initial setup, 24 and 48 hours later. Captured bubble of oxygen is visibly growing from elodea plant under funnel.

Mrs. Dennings Honors Chemistry class modeling Ernest Rutherford’s discovery of the atomic structure being mostly empty space with a dense center core. Calculations of their data that hopefully matches his to follow. #RHSScience #HonorsChem @RHSRaiders @dentonisd

Mr. French’s Biology classes working with microscopes to see different types of tissues and cells along with their characteristics. Cell pictures taken by students through microscope. (Canine Esophageal Lining & Water Lily Stem) #RHSScience @RHSRaiders @dentonisd

Spending time in the lab with microscopes in our introduction to eukaryotic cells. Love hearing the “Oh Wow!” and “Look at this!” comments from my students. 🔬 #RHSScience #Microscopes @RHSRaiders @dentonisd

Introducing the concept of enzymes today with a lab focused on bromelain, (found in pineapples) and how it impacts gelatin. 🍍 Great to hear students discovering the concept of denatured enzymes on their own with canned vs fresh. #RHSScience #Enzymes @RHSRaiders @dentonisd

My 5th block determining the “theme of the tub” with our initial biomolecule lesson. Each collection of items will ultimately connect to a specific molecule based on function. #RHSScience #DentonISDDelivers @RHSRaiders @dentonisd

Mr. French’s Biology classes started learning about lipids today and their function in forming the cell membrane. Followed that up with building the membrane on their class wall cell model. Will be fun to see the model grow through the year. #RHSScience @RHSRaiders @dentonisd

Great seeing our science classes getting into the routine. Mrs Savage’s AP Phys investigating speed, Coach Malone’s Anatomy & Physiology classes creating cadavers and my classes digging into the value of data. Let’s Go! #RHSScience @RHSRaiders
