This is an integration of science leaf observations with musical composition for early elementary students.
This activity is a lab where students will design an experiment dealing with one of the five senses. Students will collect data outside of class, write a formal lab write up as well as a group presentation on their findings.
This pathway introduces the design of guide RNAs to disrupt a macrophage gene with the gene editing tool CRISPR-Cas9. Afterwards, a DNA cleavage assay is created to test how well the designed gRNAs work.
These are resources that will provide teachers with further information on the isopods used in the experiments.
This video from Nature offers a description of desirable traits in beef and dairy cattle.
In this activity, students will investigate how much chlorophyll is in olive oil using a Varnier Spectrometer. Students will measure and analyze the visible light absorbance spectra of three standard olive oils obtained from any supermarket: extra virgin, regular, and light.
This activity is a field investigation where students gather population data on bird species. The students will create bar graphs and interpret their findings. Based on their experiences and data, they will write an answer to the guiding question.
This activity combines field exercise soil collection with lab analysis of soil bulk density. Students develop a lab procedure to measure density and analyze data using Microsoft Excel computer software.
In this video segment from Nature, learn about six different breeds of cattle.
In this interactive demonstration students will make observations of diffusion of a semi permeable membrane and be able to compare these observations to the functions of a cell membrane.
This pathway explores the concepts of diffusion and osmosis and the factors, like size, that impact the ability of molecules to diffuse across a membrane. There are several opportunities throughout the pathway to experiment with these concepts through simulations.
In a multi-week experiment, student teams gather biogas data from the mini-anaerobic digesters that they build to break down different types of food waste with microbes. Using plastic soda bottles for the mini-anaerobic digesters and gas measurement devices, they compare methane gas production from decomposing hot dogs, diced vs. whole. They monitor and measure the gas production, then graph and analyze the collected data. Students learn how anaerobic digestion can be used to biorecycle waste (food, poop or yard waste) into valuable resources (nutrients, biogas, energy).
Met deze simulatie kunt u een restrictiedigestie oefenen in een virtuele labomgeving. Restrictie-enzymen worden gebruikt om de DNA-strengen van twee plasmiden te knippen; dit levert DNA-fragmenten op met complementaire kleverige uiteinden, die opnieuw kunnen worden samengevoegd om een recombinant plasmide te creëren.
In questo video, Monique dimostra come eseguire una digestione degli enzimi di restrizione in laboratorio.
In questo video, Monique dimostra come eseguire una digestione degli enzimi di restrizione in laboratorio.
Questa simulazione offre l’opportunità di praticare una digestione da restrizione in un laboratorio virtuale. Gli enzimi di restrizione vengono utilizzati per tagliare i filamenti di DNA di due plasmidi, per produrre frammenti di DNA con estremità coesive complementari che possono essere riassemblati per creare un plasmide ricombinante.
Cette simulation permet de s’entraîner à réaliser une digestion par restriction dans un environnement de laboratoire virtuel. Les enzymes de restriction sont utilisés pour couper les brins d’ADN de deux plasmides, en produisant des fragments d’ADN dotés d’extrémités collantes complémentaires pouvant être réassemblées pour créer un plasmide recombinant.
The digestive system is investigated in this learning activity to help participants learn how food is broken down and prepared for absorption, and list the components of the digestive system as well as their functions. Organs investigated include the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus.
En este video, Monique demuestra cómo realizar una digestión con enzimas de restricción en el laboratorio.
Esta simulación ofrece la oportunidad de practicar una digestión de restricción en un laboratorio virtual. Las enzimas de restricción se utilizan para cortar las cadenas de ADN de dos plásmidos, lo que produce fragmentos de ADN con extremos cohesivos complementarios que pueden volver a ensamblarse para crear un plásmido recombinante.
